业务信息处理方法、装置及***Business information processing method, device and system

技术领域Technical field

本公开涉及通信技术领域，例如涉及一种业务信息处理方法、装置及***。The present disclosure relates to the field of communications technologies, and, for example, to a service information processing method, apparatus, and system.

背景技术Background technique

互联网的业务正向着多元化，高品质的方向发展，尤其随着移动网络和物联网的发展，对传统互联网提出了更高的要求。传统互联网主要是提供信息和内容，在互联网的发展趋势下，传统互联网有必要进行变革。软件定义网络(Software Defined Network，SDN)是一种新型网络创新架构，是网络虚拟化的一种实现方式。SDN可以将网络设备控制面与数据面分离开来，从而实现网络流量的灵活控制，使网络作为管道变得更加智能。网络功能虚拟化(Network Function Virtualization，NFV)可以通过使用通用性硬件以及虚拟化技术，承载更多功能的软件处理，从而降低昂贵的网络设备成本，还可以通过软硬件解耦及功能抽象，使网络设备功能不依赖于专用硬件，资源可以充分灵活共享，实现新业务的快速开发和部署，并可以基于实际业务需求进行自动部署、弹性伸缩、故障隔离和自愈等。将SDN和NFV技术与互联网的业务结合起来，能够提供更好的服务，但对网络也提出更高的要求。The Internet business is diversified and high-quality development, especially with the development of mobile networks and the Internet of Things, which puts higher demands on the traditional Internet. The traditional Internet mainly provides information and content. Under the development trend of the Internet, the traditional Internet needs to be changed. Software Defined Network (SDN) is a new type of network innovation architecture, which is an implementation of network virtualization. SDN can separate the control plane of the network device from the data plane, thereby achieving flexible control of network traffic and making the network more intelligent as a pipeline. Network Function Virtualization (NFV) can reduce the cost of expensive network equipment by using versatile hardware and virtualization technology to carry more functional software processing. It can also be decoupled by hardware and software and functional abstraction. The function of the network device does not depend on the dedicated hardware. The resources can be fully flexibly shared, and the rapid development and deployment of new services can be realized. The automatic deployment, elastic scaling, fault isolation, and self-healing can be performed based on actual service requirements. Combining SDN and NFV technologies with the Internet's services can provide better services, but it also places higher demands on the network.

网络传输技术通常有IPv4、IPv6、多协议标签交换(Multi-Protocol Label Switch，MPLS)、光交换以及位索引显式复制(Bit Index Explicit Replication，BIER)等。随着网络的发展，同样的网络通常可以支持多种网络传输技术，多种传输技术的调度使用也是当前网络管理和控制的一大难题。当不同业务需要使用不同的传输技术时，需要进行复杂的配置，业务灵活性很差，而且效果往往达不到要求。Network transmission technologies generally include IPv4, IPv6, Multi-Protocol Label Switch (MPLS), optical switching, and Bit Index Explicit Replication (BIER). With the development of the network, the same network can usually support multiple network transmission technologies, and the scheduling and use of multiple transmission technologies is also a major problem in current network management and control. When different business needs When using different transmission technologies, complex configurations are required, business flexibility is poor, and the effects are often not met.

网络可以提供业务的传送服务，因此路由协议是最重要的组成部分。网络的内部路由协议包括内部网关协议(Interior Gateway Protocol，IGP)协议，IGP包括开放式最短路径优先(OSPF Open Shortest Path First，OSPF)和中间***到中间***(Intermediate System-to-Intermediate System，ISIS)协议等。边界网关协议(Border Gateway Protocol，BGP)是用来处理域间路由的路由协议，能够支持因特网级的路由量。随着网络的变化，BGP技术也在不断地适应和发展。BGP链路状态(BGP-Link-State，BGP-LS)技术用于将网络中的具体链路等信息传递给各种应用层控制器，该控制器可以为虚拟的控制模块，例如包括应用层流量优化(Application-Layer Traffic Optimization，ALTO)模块和链路计算单元(Path Computation Elements，PCE)等，以使控制层可以掌握整个网络的链路信息，能够更好的规划业务数据报文的传送。The network can provide the delivery service of the service, so the routing protocol is the most important component. The internal routing protocols of the network include the Interior Gateway Protocol (IGP) protocol. The IGP includes OSPF Open Shortest Path First (OSPF) and Intermediate System-to-Intermediate System (ISIS). ) Agreement, etc. The Border Gateway Protocol (BGP) is a routing protocol used to handle inter-domain routing and can support Internet-level routing. As the network changes, BGP technology is constantly adapting and developing. The BGP-Link-State (BGP-LS) technology is used to transmit information such as specific links in the network to various application layer controllers. The controller can be a virtual control module, for example, including an application layer. Application-Layer Traffic Optimization (ALTO) module and Link Computation Elements (PCE), etc., so that the control layer can grasp the link information of the entire network, and can better plan the transmission of service data packets. .

然而，控制器还不能实现统一管理业务数据报文传输，业务数据报文传输安全性低，控制器的控制能力低，且网络资源的调度不灵活。However, the controller cannot implement unified management of service data packet transmission, the security of service data packet transmission is low, the control capability of the controller is low, and the scheduling of network resources is not flexible.

图4是本实施例提供的网络架构示意图，由中间节点和边缘节点组成。因为SDN或NFV技术的发展，通过控制器来实现集中化控制，可以提高网络的安全性和可靠性，提高网络的利用率。对于网络传送的业务信息，通常只能够采取在边缘节点之间的交互方式，由边缘节点对业务信息进行管理和交互，并进行相应的处理，并没有渠道发送给控制器，导致控制器不能对业务信息进行管理。FIG. 4 is a schematic diagram of a network architecture provided by the embodiment, which is composed of an intermediate node and an edge node. Because of the development of SDN or NFV technology, centralized control through the controller can improve the security and reliability of the network and improve the utilization of the network. For the service information transmitted by the network, it is usually only possible to adopt an interaction mode between the edge nodes, and the edge node manages and interacts with the service information, and performs corresponding processing, and no channel is sent to the controller, so that the controller cannot Business information is managed.

边缘节点之间的信息交互，通常建立在边缘节点的全连接基础上，但这种全连接的方式，在边缘节点数量较多的情况下，会导致资源被大量消耗，信息交互的效率也较低。BGP协议中引入了路由反射机制来实现路由信息的反射功能，但因为反射的原理可能会导致部分路由信息丢失，使得反射节点本身成为性能瓶颈。业务信息的交互通过BGP反射功能来实现也不符合网络的分层原则。The information interaction between the edge nodes is usually based on the full connection of the edge nodes. However, in the case of a large number of edge nodes, the full connection method leads to a large consumption of resources and the efficiency of information interaction. low. The route reflection mechanism is introduced in the BGP protocol to implement the reflection function of the routing information. However, because the reflection principle may cause partial routing information to be lost, the reflection node itself becomes a performance bottleneck. The interaction of service information is implemented by the BGP reflection function and does not conform to the layering principle of the network.

本实施例可以实现建立边缘节点与控制器之间的业务信息通讯机制，将业务信息传递给控制器，实现业务的发布与订阅，使得边缘节点之间无需进行业务信息的交互，而是由控制器来控制业务的发布与订阅，能够更好的实现业务的控制，网络安全性更高，网络资源调度更智能，也更符合网络的发展趋势。In this embodiment, the service information communication mechanism between the edge node and the controller is established, and the service information is transmitted to the controller to implement the service advertisement and subscription, so that the edge nodes do not need to exchange business information, but are controlled by To control the release and subscription of services, it is better to achieve business control, network security is higher, network resource scheduling is more intelligent, and it is more in line with the development trend of the network.

其中，控制器可以是实体的设备，也可以是虚拟控制模块或者虚拟控制设备，本实施例对此不作限定，以下统一简写为控制器。The controller may be a physical device, or may be a virtual control module or a virtual control device. This embodiment is not limited thereto, and is hereinafter abbreviated as a controller.

将业务的发布与订阅信息通过BGP扩展传递给控制器时，可以根据业务的特点来进行扩展定义。对于不同的业务，进行不同的类型区别。其中，取消订阅和取消业务的发布也可以采用与业务的发布与订阅同样的处理方式。When the service release and subscription information is transmitted to the controller through the BGP extension, the extension definition can be performed according to the characteristics of the service. Different types of differences are made for different services. Among them, the unsubscribe and cancel business release can also be handled in the same way as the business release and subscription.

图5是本实施例提供的一种业务处理流程图，如图5所示，该流程可以包括以下步骤： FIG. 5 is a flowchart of a service process provided by this embodiment. As shown in FIG. 5, the process may include the following steps:

在步骤502中，业务发布者和业务订阅者分别与控制器建立BGP连接。In step 502, the service publisher and the service subscriber establish a BGP connection with the controller, respectively.

其中，上述连接可以为链接的形式。Wherein, the above connection may be in the form of a link.

在步骤504中，BGP连接建立成功后，业务发布者通过BGP扩展将业务发布信息发送给控制器，业务订阅者通过BGP扩展将业务订阅信息发送给控制器。In step 504, after the BGP connection is successfully established, the service publisher sends the service release information to the controller through the BGP extension, and the service subscriber sends the service subscription information to the controller through the BGP extension.

在步骤506中，控制器将业务信息进行处理后，进行业务关联。In step 506, after the controller processes the service information, the service association is performed.

其中，网络中的节点可以作为业务发布者，也可以作为业务订阅者，在有多个节点发布相同的业务信息时，控制器可以根据管理策略进行业务信息处理，选择一个业务发布者为所有的业务订阅者服务；也可以将不同的业务订阅者分配给不同的业务发布者。The node in the network can serve as a service publisher or a service subscriber. When multiple nodes publish the same service information, the controller can process the service information according to the management policy, and select a service publisher for all. Service subscriber service; different service subscribers can also be assigned to different service publishers.

在步骤508中，控制器将订阅者信息发送给业务发布者。In step 508, the controller sends the subscriber information to the service publisher.

在步骤510中，业务发布者根据控制器下发的订阅者信息，向业务订阅者发送业务相关数据流量。In step 510, the service publisher sends the service-related data traffic to the service subscriber according to the subscriber information sent by the controller.

图6是本实施例提供的一种有性能测量等需求的业务处理流程图，如图6所示，该流程可以包括以下步骤：FIG. 6 is a flowchart of a service process required for performance measurement and the like according to the embodiment. As shown in FIG. 6, the process may include the following steps:

在步骤602中，业务发布者和业务订阅者分别与控制器建立BGP连接。In step 602, the service publisher and the service subscriber establish a BGP connection with the controller, respectively.

在步骤604中，BGP连接建立成功后，业务发布者通过BGP扩展形式将业务发布信息发送给控制器，业务订阅者通过BGP扩展形式将业务订阅信息发送给控制器。In step 604, after the BGP connection is successfully established, the service publisher sends the service release information to the controller through the BGP extension form, and the service subscriber sends the service subscription information to the controller through the BGP extension form.

其中，业务订阅消息中可以包括性能测量信息，即业务订阅者在发送业务订阅信息的时，声明自己有性能测量等需求。The service subscription message may include performance measurement information, that is, when the service subscriber sends the service subscription information, it declares that it has performance measurement requirements.

在步骤606中，控制器将业务信息进行处理后，将业务发布者与业务订阅者进行业务关联，当业务订阅者有性能测量等需求时，控制器可以向业务订阅者发送业务发布者的信息。In step 606, after the controller processes the service information, the service publisher associates the service with the service subscriber. When the service subscriber has performance measurement requirements, the controller can subscribe to the service. Send the information of the business publisher.

在步骤608中，控制器将订阅者信息发送给业务发布者，将发布者信息发送给业务订阅者。In step 608, the controller sends the subscriber information to the service publisher and the publisher information to the service subscriber.

在步骤610中，业务发布者根据控制器下发的订阅者信息，向业务订阅者发送业务相关数据流量，并在数据流量中标明自身的业务发布者信息。In step 610, the service publisher sends the service-related data traffic to the service subscriber according to the subscriber information sent by the controller, and indicates its own service publisher information in the data traffic.

其中，业务发布者信息可以是业务发布者的IP地址，或者是其他形式的用于与其他业务发布节点相区别的标识信息。The service publisher information may be an IP address of the service publisher, or other forms of identification information used to distinguish from other service publishing nodes.

图7是本实施例提供的另一种业务处理流程图，如图7所示，该流程包括以下步骤：FIG. 7 is another flow chart of service processing provided by this embodiment. As shown in FIG. 7, the process includes the following steps:

在步骤702中，业务发布者和业务订阅者分别与控制器建立BGP连接。In step 702, the service publisher and the service subscriber respectively establish a BGP connection with the controller.

在步骤704中，BGP连接建立成功后，业务发布者通过BGP扩展形式将业务发布信息发送给控制器，业务订阅者通过BGP扩展形式将业务订阅信息发送给控制器。In step 704, after the BGP connection is successfully established, the service publisher sends the service release information to the controller through the BGP extension form, and the service subscriber sends the service subscription information to the controller through the BGP extension form.

在步骤706中，控制器将业务信息进行处理后，将业务发布者和业务订阅者进行业务关联，判断业务信息是否为有特别要求的业务，比如安全要求较高的业务，或者是建立特定隧道来保障业务信息传输的业务。In step 706, after the controller processes the service information, the service publisher and the service subscriber are associated with each other to determine whether the service information is a service with special requirements, such as a service with high security requirements, or a specific tunnel is established. To protect the business of business information transmission.

在步骤708中，如果是安全要求较高的业务，则控制器将订阅者信息发送给业务发布者，同时控制器发送密钥信息给业务订阅者。如果是需要建立特定隧道来保障业务信息传输的业务，则控制器将订阅者信息发布给业务发布者，并将发布者信息发送给业务订阅者，同时将隧道建立的信息发送给业务发布者和业务订阅者，业务发布者和订阅者将进行隧道信息的交互，从而建立隧道来保障业务传输。In step 708, if it is a service with higher security requirements, the controller sends the subscriber information to the service publisher, and the controller sends the key information to the service subscriber. If it is a service that needs to establish a specific tunnel to ensure the transmission of service information, the controller issues the subscriber information to the service publisher, and sends the publisher information to the service subscriber, and simultaneously sends the tunnel establishment information to the service publisher and Service subscribers, service publishers, and subscribers will interact with tunnel information to establish tunnels to secure service transmission.

其中，业务发布者和业务订阅者还可以进行密钥协商，确保所传输的数据安全可靠。不同的业务订阅者还可能有不同的加密或者隧道建立需求，控制器可以下发不同的密钥和隧道建立需求给业务发布者，实现业务数据流量的精细化管理。Among them, the service publisher and the service subscriber can also perform key negotiation to ensure the transmitted data. Safe and reliable. Different service subscribers may also have different encryption or tunnel establishment requirements. The controller may issue different keys and tunnels to establish requirements for service publishers to implement fine-grained management of service data traffic.

在步骤710中，如果是安全要求较高的业务，业务发布者可以直接使用控制器下发的密钥，对业务相关数据流量进行加密后，发送给业务订阅者，或者业务发布者使用与业务订阅者协商后的密钥，对业务相关数据流量进行加密后，发送给业务订阅者。In step 710, if the service is a service with a high security requirement, the service publisher can directly use the key sent by the controller to encrypt the service-related data traffic, and then send it to the service subscriber, or the service publisher uses the service. After the subscriber negotiates the key, the service-related data traffic is encrypted and sent to the service subscriber.

如果是需要建立特定隧道来保障业务信息传输的业务，则业务发布者使用与订阅者建立的隧道进行业务相关数据流量的传输。If it is a service that needs to establish a specific tunnel to ensure the transmission of service information, the service publisher uses the tunnel established by the subscriber to transmit the service-related data traffic.

在上述实施例提供的几种处理流程中，如果使用BGP-LS扩展来传输业务信息，则业务发布者和订阅者与控制器建立BGP-LS连接，不用再建立单独的BGP连接。其他的步骤与BGP连接时相同。In the process flow provided by the foregoing embodiment, if the BGP-LS extension is used to transmit the service information, the service publisher and the subscriber establish a BGP-LS connection with the controller, and no separate BGP connection is established. The other steps are the same as when connecting to BGP.

在上述实施例提供的几种处理流程中，控制器还可以根据业务需求，下发业务数据报文的网络传输方式，使得业务发布者可以以特定的网络传输方式传输业务相关数据流量，其中，上述网络传输方式包括但不限于IPv4、IPv6、BIER、MPLS和多种隧道传输方式等。In the processing flow provided by the foregoing embodiment, the controller may also deliver the network transmission mode of the service data packet according to the service requirement, so that the service publisher can transmit the service-related data traffic in a specific network transmission manner, where The above network transmission methods include, but are not limited to, IPv4, IPv6, BIER, MPLS, and various tunnel transmission methods.

本实施例中的业务发布信息和业务订阅信息前后顺序并不固定，并非一定要先有业务发布信息，后有业务订阅信息，控制器可以在接收到业务发布信息或业务订阅信息后进行存储以用于后续处理。The order of the service release information and the service subscription information in this embodiment is not fixed. The service release information does not have to be first, and the service subscription information is used. The controller can store the service release information or the service subscription information after receiving the service release information. Used for subsequent processing.

图8是本实施例提供的业务订阅撤销的处理流程图，如图8所示，该流程可以包括以下步骤：FIG. 8 is a flowchart of processing a service subscription revocation provided in this embodiment. As shown in FIG. 8, the process may include the following steps:

在步骤802中，业务订阅者不再需要一业务相关数据流量时，发送业务订阅撤销信息给控制器。 In step 802, when the service subscriber no longer needs a service related data traffic, the service subscription revocation information is sent to the controller.

在步骤804中，控制器对业务订阅撤销信息进行处理后，如果还有其他的业务订阅者存在，则发送更新后的业务订阅者信息给业务发布者。如果没有其他的业务订阅者存在，则发送空的订阅者信息给业务发布者，使得业务发布者不再发送该业务相关数据流量。In step 804, after the controller processes the service subscription revocation information, if there are other service subscribers, the updated service subscriber information is sent to the service publisher. If no other service subscribers exist, the empty subscriber information is sent to the service publisher, so that the service publisher no longer sends the service related data traffic.

其中，从多个业务订阅者信息中除去发送业务订阅撤销信息的业务订阅者之后可以得到上述更新后的业务订阅者信息。如果在业务发布者和业务订阅者之间建立了特殊隧道或者加密通道，则控制器还可以通知业务发布者和业务订阅者拆除已建立的特殊隧道或者加密通道。The updated service subscriber information may be obtained after the service subscriber that sends the service subscription revocation information is removed from the plurality of service subscriber information. If a special tunnel or encrypted channel is established between the service publisher and the service subscriber, the controller can also notify the service publisher and the service subscriber to tear down the established special tunnel or encrypted channel.

在步骤806中，如果还有其他的业务订阅者存在，业务发布者将继续传输业务相关数据流量给更新后的业务订阅者。如果没有其他订阅者存在，业务发布者不再传输业务相关数据流量。In step 806, if there are other service subscribers present, the service publisher will continue to transmit service related data traffic to the updated service subscriber. If no other subscribers exist, the business publisher no longer transmits business-related data traffic.

其中，如果拆除业务发布者和订阅者之间的特殊隧道或者加密通道，则业务发布者和业务订阅者进行相应的拆除工作。If the special tunnel or encrypted channel between the service publisher and the subscriber is removed, the service publisher and the service subscriber perform corresponding demolition work.

图9是本实施例提供的业务发布撤销处理流程图，如图9所示，该流程可以包括以下步骤：FIG. 9 is a flowchart of a service release revocation process provided by this embodiment. As shown in FIG. 9, the process may include the following steps:

在步骤902中，业务发布者无法发送一业务相关数据流量时，发送业务订阅撤销信息给控制器。In step 902, when the service publisher cannot send a service related data traffic, the service subscription revocation information is sent to the controller.

在步骤904中，控制器进行业务订阅撤销信息处理后，如果没有其他发布者存在，则控制器可以发送业务撤销信息给业务订阅者。In step 904, after the controller performs the service subscription revocation information processing, if no other publisher exists, the controller may send the service revocation information to the service subscriber.

其中，如果业务发布者和订阅者之间建立了特殊隧道或者加密通道，则控制器将通知业务发布者和订阅者拆除已建立的特殊隧道或者加密通道。Wherein, if a special tunnel or an encrypted channel is established between the service publisher and the subscriber, the controller will notify the service publisher and the subscriber to tear down the established special tunnel or encrypted channel.

在步骤906中，如果有发布相同业务的其他业务发布者存在，控制器发送更新后的订阅者信息给新的业务发布者。 In step 906, if there are other service publishers that publish the same service, the controller sends the updated subscriber information to the new service publisher.

例如，业务发布者A向业务订阅者A发送业务流量数据，业务发布者B向业务订阅者B发送业务流量数据，之后业务发布者A向控制器发送了业务撤销信息，则控制器可以将业务订阅者A和业务订阅者B作为更新后的业务订阅者信息发送给业务发布者B，使得业务发布者B为业务订阅者A提供业务流量数据，保证业务订阅者A能够正常接收业务流量数据。其中，控制器还可以发送提示信息给业务订阅者，通知业务订阅者业务发布者的变化信息。For example, the service publisher A sends the service traffic data to the service subscriber A, the service publisher B sends the service traffic data to the service subscriber B, and then the service publisher A sends the service revocation information to the controller, and the controller can send the service. The subscriber A and the service subscriber B are sent to the service publisher B as the updated service subscriber information, so that the service publisher B provides the service subscriber A with service traffic data, and ensures that the service subscriber A can receive the service traffic data normally. The controller may also send a prompt message to the service subscriber to notify the service subscriber of the change information of the service publisher.

其中，如果业务发布者和更新后的业务订阅者需要建立新的特殊隧道或者加密通道，则控制器通知业务发布者和业务订阅者建立新的特殊隧道或者加密通道。If the service publisher and the updated service subscriber need to establish a new special tunnel or an encrypted channel, the controller notifies the service publisher and the service subscriber to establish a new special tunnel or encrypted channel.

在步骤908中，新的业务发布者发送业务相关数据流量给业务订阅者。In step 908, the new service publisher sends the service related data traffic to the service subscriber.

以下实施例是业务发布者、业务订阅者与控制器之间进行交互时交互信息的格式示例，这里以TLV的格式来进行说明，实际上也可以是其他协议扩展发布形式。The following embodiment is an example of the format of the interaction information when the service publisher, the service subscriber, and the controller interact with each other.

The format of other types of service subscriber information may be in an information format defined in the service release process, and the format may be adaptively adjusted, and is not described here.

图22是本实施例提供的业务订阅者信息的格式示意图，如图22所示，因为控制要求，控制器不会直接将业务订阅者的信息发送给业务发布者，而是直接下发基于业务流量的流量信息(flow info)，可以包括业务类型和业务流量的转发策略(forwarding policy)。业务发布者根据该转发策略来进行业务相关数据流量的发送。多种业务类型可采用业务发布流程中定义的信息格式，格式可适应性调整，这里不再累述。Figure 22 is a schematic diagram of the format of the service subscriber information provided in this embodiment. As shown in Figure 22, the controller does not directly send the information of the service subscriber to the service publisher, but directly delivers the service based on the service. The traffic information of the traffic (flow info) can include the forwarding policy of the service type and service traffic. The service publisher transmits the service-related data traffic according to the forwarding policy.

图23是本实施例提供的网络结构示意图，如图23所示，边缘节点可以来自不同的互联网服务提供商(Internet Service Provider，ISP)，例如，节点1属于ISP1，节点2和3属于ISP2，节点4和5属于ISP4，节点6属于ISP3。不同ISP之间通过一个控制器设备来进行业务的管理。，不同的节点也可以来自不同的域，本实施例对此不作限定。FIG. 23 is a schematic diagram of the network structure provided by this embodiment. As shown in FIG. 23, the edge nodes may be from different Internet Service Providers (ISPs). For example, node 1 belongs to ISP1, and nodes 2 and 3 belong to ISP2. Nodes 4 and 5 belong to ISP4, and node 6 belongs to ISP3. Business management is performed by a controller device between different ISPs. Different nodes can also come from no The same domain is not limited in this embodiment.

例如，节点1和节点4都有同一IPTV业务发布的资格，两个节点与控制器建立BGP连接后，可以通过BGP扩展进行IPTV相关业务信息的发布。节点3和节点6有订阅IPTV业务的需求，两者在与控制器建立BGP连接后，可以将IPTV业务订阅需求发送给控制器。控制器在进行IPTV业务的处理时，根据节点3和6的需求信息，可以选择节点1作为业务发布者，将节点3和节点6的信息作为业务订阅者信息发送给节点1。节点1可以根据从控制器收到的IPTV业务订阅者信息，发送该IPTV相关的业务数据流量给节点3和节点6。For example, both the node 1 and the node 4 are eligible for the same IPTV service. After the two nodes establish a BGP connection with the controller, the BGP extension can be used to advertise the IPTV-related service information. Node 3 and Node 6 have the requirement to subscribe to the IPTV service. After establishing a BGP connection with the controller, the two can send the IPTV service subscription requirement to the controller. When the controller performs the processing of the IPTV service, according to the demand information of the nodes 3 and 6, the node 1 can be selected as the service publisher, and the information of the node 3 and the node 6 is sent to the node 1 as the service subscriber information. The node 1 can send the IPTV-related service data traffic to the node 3 and the node 6 according to the IPTV service subscriber information received from the controller.

再例如，假设节点1发布的业务信息带有高清特性，节点4发布的业务信息没有高清特性，节点3的订阅信息带有高清特性要求，节点6发布的订阅信息没有高清特性要求，则控制器可以根据业务订阅者的不同需求，发送包括节点3的信息的订阅者信息给节点1，发送包括节点6的信息的订阅者信息给节点4，由此可以实现对特性不同的相同业务进行区分服务。如果有不同的业务加密信息和隧道要求信息，也可以采用类似的方式实现服务。For example, suppose that the service information advertised by node 1 has high-definition characteristics, the service information advertised by node 4 has no high-definition characteristics, the subscription information of node 3 has high-definition characteristics, and the subscription information advertised by node 6 does not have high-definition characteristics, and the controller The subscriber information including the information of the node 3 can be sent to the node 1 according to the different needs of the service subscriber, and the subscriber information including the information of the node 6 is sent to the node 4, thereby realizing the differentiated service for the same service with different characteristics. . If there are different service encryption information and tunneling requirements, the service can be implemented in a similar manner.

当多个节点发布发布相同特性的同一业务信息时，控制器可以根据网络链路的负担情况，让多个业务发布者同时发布服务给不同的业务订阅者，可以实现充分利用网络资源，保障服务质量。When multiple nodes advertise the same service information of the same feature, the controller can allow multiple service publishers to simultaneously publish services to different service subscribers according to the burden of the network link, so that network resources can be fully utilized and services can be guaranteed. quality.

控制器为实现安全控制，也可以不直接下发业务相关信息给业务发布者或业务订阅者，而是下发流量转发策略给业务发布者或业务订阅者，业务发布者直接根据流量转发策略完成业务相关数据流量的转发，同样订阅者直接根据流量转发策略收到相应的业务数据流量。The controller implements the security control, and may not directly deliver the service-related information to the service publisher or the service subscriber, but deliver the traffic forwarding policy to the service publisher or the service subscriber, and the service publisher directly completes the traffic forwarding policy. The forwarding of service-related data traffic, the same subscriber directly receives the corresponding service data traffic according to the traffic forwarding policy.

图24是本实施例提供的多域汇聚的网络结构示意图，如图24所示，边缘节点可以来自不同的域，域之间的通讯安全要求较高。可以由一个高级别的控制器来控制通讯。假设多个域之间有进行加密的多方语音通话的需求。FIG. 24 is a schematic structural diagram of a multi-domain aggregation network according to the embodiment. As shown in FIG. 24, edge nodes may be from different domains, and communication security requirements between domains are high. Can be controlled by a high level Controller to control communication. Assume that there is a need for multi-party voice calls for encryption between multiple domains.

业务处理时，每一个边缘节点与控制器建立BGP连接；When the service is processed, each edge node establishes a BGP connection with the controller;

每一个边缘节点发布语音业务信息给控制器，并且语音业务信息中携带相同的业务编号；每一个边缘节点向控制器订阅该语音业务，并且在业务订阅信息中附带安全加密需求；控制器收集到发布的语音业务信息和业务订阅信息后，进行业务的处理以及业务关联，对每个发布业务的节点发送包含其他节点信息的订阅者信息。比如发送给节点1的相应语音业务订阅者信息中，可以包含边缘节点2到边缘节点6的信息，还可以包括安全密钥信息。同样，发送给节点2的相应语音业务订阅者信息中，可以包含边缘节点1、边缘节点3到边缘节点6的信息，也可以包含安全密钥信息。以此类推，最终所有的边缘节点都能够接收包含其他所有节点信息的订阅者信息，以及安全密钥信息，由此多个边缘节点之间可以进行安全的加密的多方语音通话。Each edge node issues voice service information to the controller, and the voice service information carries the same service number; each edge node subscribes the voice service to the controller, and the security encryption request is included in the service subscription information; the controller collects After the published voice service information and the service subscription information, the service processing and the service association are performed, and the subscriber information including the other node information is sent to each node that publishes the service. For example, the corresponding voice service subscriber information sent to the node 1 may include information of the edge node 2 to the edge node 6, and may also include security key information. Similarly, the corresponding voice service subscriber information sent to the node 2 may include information of the edge node 1, the edge node 3 to the edge node 6, and may also include security key information. By analogy, all edge nodes are finally able to receive subscriber information containing all other node information, as well as security key information, whereby a secure encrypted multi-party voice call can be made between multiple edge nodes.

假设这个网络的多个边缘节点之间通过建立特定的隧道来保障加密语音通话，则内一个边缘节点还可以发送隧道及需要保障的带宽信息给控制器，控制器在下发订阅者信息给每一个边缘节点时，同时发送需要建立的隧道及带宽需求的信息。Assuming that a plurality of edge nodes of the network establish a specific tunnel to secure the encrypted voice call, the inner edge node can also send the tunnel and the bandwidth information to be guaranteed to the controller, and the controller sends the subscriber information to each one. At the edge of the node, the information about the tunnel and bandwidth requirements that need to be established is sent at the same time.

在每一个边缘节点收到订阅者信息以及密钥和隧道要求后，进行符合带宽要求的隧道建立，隧道建立完成后，即可将相关的加密语音流量在特定的隧道上进行交互，由此实现高控制性的安全的多方互通的语音业务信息的传送。After each edge node receives the subscriber information and the key and tunnel requirements, the tunnel is established according to the bandwidth requirement. After the tunnel is established, the related encrypted voice traffic can be exchanged on a specific tunnel. Highly controllable secure multi-party interworking voice service information transmission.

图25是本实施例提供的另一网络结构的示意图，在图25中，节点1所连接网络中有提供DNS业务的服务器设备，如DNS服务器，节点5和节点6所连接的网络有需要DNS业务的用户。25 is a schematic diagram of another network structure provided by this embodiment. In FIG. 25, a server device that provides DNS service, such as a DNS server, is connected to the network connected to the node 1, and the network connected to the node 5 and the node 6 needs a DNS. Business users.

在进行业务处理时，节点1，节点5和节点6分别与控制器建立BGP连接。节点1发布DNS业务信息给控制器，节点5和节点6也分别发送DNS业务订阅信息给控制器。控制器收集到这些业务相关信息后，进行分析处理和业务关联；控制器下发包含节点5和节点6的信息的订阅者信息给节点1，下发包含节点1的信息的业务发布者信息给节点5和节点6。节点5和节点6根据所提供的DNS业务发布信息使用DNS业务。在DNS业务使用过程中，可能有设备对DNS服务器发起了攻击，或者因为安全策略的需要，DNS服务器不能再以之前的地址继续提供DNS服务，而是需要进行跳变，则节点1发布包含跳变地址信息的业务信息给控制器，控制器根据业务关联信息，将DNS服务器跳变地址发送给节点5和节点6，即控制器发送给节点5和节点6的业务发布者信息包含跳变后的DNS服务器地址。使节点5和节点6将根据新的业务发布者信息来使用DNS业务。When performing business processing, node 1, node 5, and node 6 establish a BGP connection with the controller, respectively. Node 1 issues DNS service information to the controller, and node 5 and node 6 also send DNS service subscription information to the controller, respectively. The controller collects the information about the service and performs the analysis processing and the service association. The controller sends the subscriber information including the information of the node 5 and the node 6 to the node 1, and delivers the service publisher information including the information of the node 1. Node 5 and Node 6. The node 5 and the node 6 use the DNS service according to the provided DNS service distribution information. During the use of the DNS service, there may be a device that attacks the DNS server, or because the security policy requires the DNS server to continue to provide the DNS service at the previous address, but needs to perform a jump. Transmitting the service information of the address information to the controller, and the controller sends the DNS server hopping address to the node 5 and the node 6 according to the service association information, that is, the service publisher information sent by the controller to the node 5 and the node 6 includes the hopping DNS server address. Let node 5 and node 6 use the DNS service based on the new service publisher information.

图26是本实施例提供的MVPN业务的网络结构示意图，节点1和节点2所连网络分别为MVPN1和MVPN2，MVPN1和MVPN2均可以提供直播业务。节点4，节点5和节点6所连网络分别有需要MVPN中的直播业务的用户。FIG. 26 is a schematic diagram of the network structure of the MVPN service provided by the embodiment. The network connected to the node 1 and the node 2 are respectively MVPN1 and MVPN2, and both MVPN1 and MVPN2 can provide live broadcast services. The network connected to node 4, node 5, and node 6 respectively has users who need live broadcast services in MVPN.

在业务处理中，每一个节点可以与控制器之间建立BGP-LS连接。节点1和节点2可以向控制器发送直播业务的相关发布信息，可以包括业务所属的MVPN信息，以及包含的直播节目内容等。节点4，节点5和节点6可以向控制器发送MVPN的直播业务订阅信息。控制器收集到这些信息后，进行业务关联，由于对直播业务的质量需求，控制器可以要求网络提供相应的带宽保障，在控制器下发订阅者信息以及发布者信息给每一个节点时，可以携带点到多点隧道的建立需求信息。In service processing, each node can establish a BGP-LS connection with the controller. The node 1 and the node 2 may send related release information of the live broadcast service to the controller, and may include MVPN information to which the service belongs, and the content of the live program included. Node 4, Node 5 and Node 6 can send MVPN live broadcast subscription information to the controller. After the controller collects the information, the service association is performed. Due to the quality requirements of the live broadcast service, the controller can request the network to provide corresponding bandwidth guarantee. When the controller sends the subscriber information and the publisher information to each node, Carrying demand-building information for point-to-multipoint tunnels.

每一个节点在收到控制器下发的信息后，节点1将会获知节点5和节点6需要相应的直播业务，则节点1直接发送点到多点隧道建立请求到节点5和节点6，然后节点5与节点6根据隧道信息，与节点1建立点到多点隧道。同样，节点2能够获知节点4订阅节点2的直播业务，因此节点2与节点4之间建立点到点的隧道。在隧道建立完成后，节点1使用点到多点隧道，以及节点2使用点到点隧道传递直播业务。After each node receives the information sent by the controller, node 1 will know that node 5 and node 6 need the corresponding live service, and node 1 directly sends the point-to-multipoint tunnel establishment request to node 5 and the node. Point 6, then node 5 and node 6 establish a point-to-multipoint tunnel with node 1 based on the tunnel information. Similarly, node 2 can know that node 4 subscribes to the live traffic of node 2, so node 2 and node 4 establish a point-to-point tunnel. After the tunnel is established, node 1 uses a point-to-multipoint tunnel, and node 2 uses a point-to-point tunnel to deliver live traffic.

假设节点3也订阅MVPN2的直播业务，节点3向控制器发起订阅请求后，控制器进行业务关联，并通知相关节点订阅者信息和发布者信息。例如，节点2获知直播业务的订阅者包括节点3和节点4，则节点2发起点到多点隧道的建立请求给节点3和节点4，建立点到多点隧道，在新的点到多点隧道建立完成前，业务仍然通过之前建立的隧道发送。在新的隧道建立完成之后，节点2通过点到多点隧道发送业务信息给节点3和节点4。It is assumed that the node 3 also subscribes to the live broadcast service of the MVPN2. After the node 3 initiates a subscription request to the controller, the controller performs service association and notifies the relevant node of the subscriber information and the publisher information. For example, if node 2 knows that the subscriber of the live broadcast service includes node 3 and node 4, node 2 initiates a point-to-multipoint tunnel setup request to node 3 and node 4, establishing a point-to-multipoint tunnel, at a new point-to-multipoint point. Before the tunnel is established, the service is still sent through the previously established tunnel. After the new tunnel is established, node 2 sends service information to node 3 and node 4 through a point-to-multipoint tunnel.

如果在隧道建立过程中因为带宽不够或者一些原因导致隧道建立不成功，节点通知业务不成功的消息给控制器，控制器接收到的业务不成功的消息对业务关联进行调整。一般的网络中，支持多种传输技术的网络的拓扑结构不同，控制器可以据此调整新的业务信息的传输策略，比如控制器可以通知节点2，节点3和节点4使用位索引显示复制(Bit Indexed Explicit Replication，BIER)技术进行业务相关数据流量传递，由此实现节点2对节点3和节点4发布直播业务。If the tunnel establishment is unsuccessful due to insufficient bandwidth or some reasons during the tunnel establishment process, the node notifies the controller of the unsuccessful service message, and the service unsuccessful message received by the controller adjusts the service association. In a general network, the topology of the network supporting multiple transmission technologies is different, and the controller can adjust the transmission strategy of the new service information according to this, for example, the controller can notify node 2, and node 3 and node 4 use the bit index to display the replication ( The Bit Indexed Explicit Replication (BIER) technology performs service-related data traffic delivery, thereby enabling Node 2 to issue live broadcast services to Node 3 and Node 4.

其中，MVPN网络也可以是VPN网络，包括三层VPN(Layer 3 VPN，L3VPN)和两层VPN(Layer 2 VPN，L2VPN)。The MVPN network can also be a VPN network, including Layer 3 VPN (L3VPN) and Layer 2 VPN (L2VPN).

其中，网络使用的技术可以包括IPv4，IPv6，MPLS(Multi-Protocol Label Switch，多协议标签交换)、光交换网络、BIER(Bit Index Explicit Replication)等各种类型的网络，这里并不作限定。The technologies used by the network may include various types of networks, such as IPv4, IPv6, MPLS (Multi-Protocol Label Switch), optical switching network, and BIER (Bit Index Explicit Replication), which are not limited herein.

图27为本实施例提供的又一网络结构示意图，节点3是用于连接互联网 (Internet)的出口路由器，节点2的用户有访问Internet的需求，通常将节点3作为业务发布者，节点2作为业务订阅者即可实现通讯。为了达到更好控制网络的结果，可以使用服务链(Service Function Chaining，SFC)技术来实现对业务数据流量的精细化控制，并且提供多类业务的设备并不集中在一台设备或者一个局域网络内部。FIG. 27 is a schematic diagram of another network structure provided by the embodiment, where the node 3 is used to connect to the Internet (Internet) egress router, the user of node 2 has the need to access the Internet. Usually, node 3 is used as a service publisher, and node 2 is used as a service subscriber to implement communication. In order to achieve better control of the network results, Service Function Chaining (SFC) technology can be used to achieve fine control of service data traffic, and devices providing multiple types of services are not centralized in one device or one local area network. internal.

如图27所示，节点1所连网络可以提供网络地址转换(Network Address Translation，NAT)功能，节点4可以提供防火墙功能，节点5可以提供认证功能，假设节点2的用户访问因特网的流量，需要经过认证，通过认证后，再经过NAT地址转换，才能发往节点3从而访问因特网网络，则由节点1发布NAT业务给控制器，节点4发布防火墙业务给控制器，节点5发布认证业务给控制器，节点3发布因特网访问业务给控制器。节点2也与控制器进行通讯，节点2除订阅因特网业务外，还发送认证需求和NAT业务需求。As shown in FIG. 27, the network connected to the node 1 can provide a network address translation (NAT) function, the node 4 can provide a firewall function, and the node 5 can provide an authentication function, and it is required that the user of the node 2 accesses the Internet traffic. After being authenticated, after passing the authentication, the NAT address translation can be sent to the node 3 to access the Internet network. Then, the node 1 issues the NAT service to the controller, the node 4 issues the firewall service to the controller, and the node 5 issues the authentication service to the control. Node 3 issues Internet access services to the controller. Node 2 also communicates with the controller. In addition to subscribing to Internet services, Node 2 also sends authentication requirements and NAT service requirements.

控制器进行业务信息处理与关联后，通知节点2的业务信息中，除了节点3的因特网访问出口信息外，还携带节点1的NAT业务信息与节点5认证业务信息，由节点2生成所订阅的业务的业务链，业务链为经过节点5的认证业务，再经过节点1的NAT业务，最后再发往节点3的因特网业务。控制器也可以直接下发编排好的业务链信息给节点2，使节点2根据下发的业务链发送相关数据流量。After the controller performs service information processing and association, the service information of the notification node 2, in addition to the Internet access exit information of the node 3, carries the NAT service information of the node 1 and the node 5 authentication service information, and the node 2 generates the subscribed The service chain of the service, the service chain is the authentication service passing through the node 5, and then passes through the NAT service of the node 1, and finally is sent to the Internet service of the node 3. The controller can also directly send the arranged service chain information to the node 2, so that the node 2 sends the relevant data traffic according to the delivered service chain.
