具体实施方式detailed description
本实施例中，宽带网络业务可以包括家庭用户和企业用户的互联网(Internet)接入、企业互联、视频优化和安全等业务。用户可以根据需要动态选择和变更业务，每种业务可以由多个物理的或虚拟的网络功能实现。In this embodiment, the broadband network service may include Internet (Internet) access, enterprise interconnection, video optimization, and security services of home users and enterprise users. Users can dynamically select and change services as needed, each of which can be implemented by multiple physical or virtual network functions.
业务链SFC包含一组业务功能(Service Function，SF)并有一定排序关系。最简单的情况下，业务链包含一个SF。在用户报文或流量进入业务链管理域时，为该用户报文或流量指定业务转发路径(Service Forwarding Path，SFP)， SFP可以是严格位置指定的路径，也可以是部分位置指定的路径。严格位置指定的路径是指确定了每个SF的具体实例的位置。SFC架构定义了业务分类功能(Service Classification Function，SCF)，用于对用户报文或流量进行分类，并在用户报文中携带的网络业务报头(Network Service Header，NSH)中包含有指定的NFP ID。控制器(Controller)可以为SCF和为业务功能提供转发的业务功能转发器(Service Function Forwarder，SFF)下发NFP ID路由表及下一跳的SF转发信息(即外层封装信息)。The service chain SFC contains a set of Service Functions (SF) and has a certain ordering relationship. In the simplest case, the business chain contains an SF. When a user packet or traffic enters the service chain management domain, a service forwarding path (SFP) is specified for the user packet or traffic. The SFP can be a path specified by a strict location or a path specified by a partial location. The path specified by the strict location refers to the location of the specific instance of each SF. The SFC architecture defines a service classification function (SCF), which is used to classify user packets or traffic, and includes a specified NFP in the Network Service Header (NSH) carried in the user packet. ID. The controller (Controller) can deliver the NFP ID routing table and the SF forwarding information of the next hop (ie, the outer package information) for the SCF and the service function forwarder (SFF) that provides the service function forwarding.
网络功能虚拟化编排器NFVO定义了网络业务，网络业务包含VNF、PNF及VNF转发表(Virtual Network Function Forwarding Graph，VNFFG)，VNFFG可以表示NFVO管理域内的VNF转发图、以及PNF和VNF的转发序列。一个网络业务可以有多个VNFFG，如管理面的VNFFG、控制面的VNFFG和数据面的VNFFG等。一个VNFFG可以描述一个网络业务或部分网络业务的一种拓扑，一个VNFFG由VNF的连接点(connection point，CP)和业务接入点(service access points，SAP)的池(pool)组成，CP和SAP分别与组成网络业务的VNF、PNF和虚拟链路(Virtual Link，VL)相连。一个VNFFG包含一个或多个网络转发路径NFP。The network function virtualization orchestrator NFVO defines the network service. The network service includes the VNF, PNF and VNF FW forwarding table (VNFFG). The VNFFG can represent the VNF forwarding map in the NFVO management domain and the forwarding sequence of the PNF and VNF. . A network service can have multiple VNFFGs, such as the VNFFG of the management plane, the VNFFG of the control plane, and the VNFFG of the data plane. A VNFFG can describe a topology of a network service or part of a network service. A VNFFG consists of a connection point (CP) of a VNF and a pool of service access points (SAP), CP and SAP is connected to the VNF, PNF, and Virtual Link (VL) that make up the network service. A VNFFG contains one or more network forwarding paths NFP.
对于宽带网络业务而言，NFVO中定义的网络业务并不是特定用户的宽带业务，而是NMS为宽带网络运营所部署网络资源层的网络业务。宽带网络业务可以有多个NFP，NFP为指定了严格路径的NFV域内的SFP。在宽带网络运维里，严格位置指定路径有助于准确管理。For broadband network services, the network service defined in NFVO is not the broadband service of a specific user, but the network service in which the NMS deploys the network resource layer of the broadband network operation. The broadband network service can have multiple NFPs, and the NFP is an SFP in the NFV domain that specifies a strict path. In broadband network operation and maintenance, strict location specified paths help to accurately manage.
宽带网络业务可以包含NFVO域内的宽带网络业务和物理网络域的网络业务。宽带网络业务可以包含：用户接入网关、网络地址转换(Network Address Translation，NAT)、家长控制、防火墙(FW)和视频优化等业务。宽带网络业务可以进行全部虚拟化，全部位于NFVO域，也可以部分网络业务位于NFVO域 内进行部分虚拟化。宽带网络业务的业务链可以包括NFVO域的单个或多个NFP，还可以包含位于NFVO域外的物理网络的业务链SFP。The broadband network service may include broadband network services in the NFVO domain and network services in the physical network domain. Broadband network services can include: user access gateways, network address translation (NAT), parental control, firewall (FW), and video optimization. Broadband network services can be fully virtualized, all located in the NFVO domain, or part of the network traffic in the NFVO domain. Partially virtualized inside. The service chain of the broadband network service may include a single or multiple NFPs of the NFVO domain, and may also include a service chain SFP of the physical network located outside the NFVO domain.

The NFVO may create a broadband network service related vBRAS or VNF according to the request of the NMS, and may create a VNFFG and a corresponding NFP for the corresponding network service.
本实施例提供一种网络架构如图7所示，客户终端设备(Customer Premise Equipment，CPE)与转发器通信，转发器在vBRAS的控制下通过不同的业务链，如SFCO、SFC1、SFC2、SFC3和SFC4，转发用户流量。This embodiment provides a network architecture. As shown in FIG. 7, a Customer Premise Equipment (CPE) communicates with a repeater, and the repeater passes different service chains under the control of the vBRAS, such as SFCO, SFC1, SFC2, and SFC3. And SFC4, forward user traffic.
本实施例中，用户接入时的宽带业务控制流程可以包括如下步骤：In this embodiment, the broadband service control process when the user accesses may include the following steps:
在步骤a1中，宽带网络的NMS定义宽带用户业务及用于用户签约的业务链；In step a1, the NMS of the broadband network defines a broadband user service and a service chain for user subscription;
如图7所示，本实施例中NMS定义了宽带用户的网络业务，该网络业务可以包含四个业务链：用于宽带用户接入控制的业务链SFCO、用于互联网接入的业务链SFC1、用于家长控制的业务链SFC2、以及用于视频优化的业务链SFC3。其中，SFC1包含转发器和虚拟化路由器(virtual Router，vRouter)等功能；SFC2包含转发器、家长控制、防火墙及vRouter等功能；SFC3包含有转发器、视频优化和vRouter等功能。其中，vRouter连接城域路由器(MR)，MR是指连 接到互联网(Internet)的路由器。As shown in FIG. 7, in this embodiment, the NMS defines a network service of a broadband user, and the network service may include four service chains: a service chain SFCO for broadband user access control, and a service chain SFC1 for Internet access. , business chain SFC2 for parental control, and business chain SFC3 for video optimization. Among them, SFC1 includes functions such as a repeater and a virtual router (vRouter); SFC2 includes functions such as a repeater, parental control, firewall, and vRouter; SFC3 includes functions such as a forwarder, video optimization, and vRouter. Among them, vRouter is connected to the Metropolitan Area Router (MR), and MR is the connection. A router that receives an Internet connection.
如果用户申请SFC1到SFC3的业务，创建签约关系并保存到AAA***。If the user applies for the service from SFC1 to SFC3, create a contractual relationship and save it to the AAA system.
NMS可以通过NFVO动态创建SFC相关的vBRAS、家长控制、防火墙、视频优化或vRouter VNF(即支持网络地址翻译(Network Address Translation，NAT)功能的虚拟化路由器)，每种VNF可以有一个或多个实例，部署SFCO到SFC3对应的VNFFG，VNFFG可以包含多个NFP，NFP可以通过控制器创建或由NMS直接创建。NMS can dynamically create SFC-related vBRAS, parental control, firewall, video optimization or vRouter VNF (that is, a virtualized router supporting Network Address Translation (NAT) function) through NFVO. Each VNF can have one or more. For example, the SFCO is deployed to the VNFFG corresponding to the SFC3, and the VNFFG may include multiple NFPs, which may be created by the controller or directly created by the NMS.
NMS在申请创建NFP时，可以同时下发SFC ID，控制器收到NFP创建请求之后，建立并保存SFC ID和NFP ID之间的映射关系。例如，NMS在申请创建SFCO对应的NFP时，多个转发器和其对应的vBRAS业务路径可以同时指定NFP流量规则为用户控制面报文类型，如增加动态主机配置协议(Dynamic Host Configuration Protocol，DHCP)或以太网上点对点协议(PPP over Ethernet，PPPoE)的控制报文的报头字段，以便识别报文类型为控制面报文。控制器接收到SFCO对应的NFP创建请求之后，建立并保存SFC ID和NFP ID的映射关系和NFP流量规则，并将所述NFP流量规则下发给转发器。When the NMS is configured to create an NFP, the NMS can send the SFC ID at the same time. After receiving the NFP creation request, the NMS establishes and saves the mapping between the SFC ID and the NFP ID. For example, when the NMS is applied to create the NFP corresponding to the SFCO, the multiple forwarders and their corresponding vBRAS service paths can simultaneously specify the NFP traffic rule as the user control plane packet type, such as adding the Dynamic Host Configuration Protocol (DHCP). Or the header field of the control packet of the PPP over Ethernet (PPPoE) on the Ethernet to identify the packet type as the control plane packet. After receiving the NFP creation request corresponding to the SFCO, the controller establishes and saves the mapping relationship between the SFC ID and the NFP ID and the NFP traffic rule, and delivers the NFP traffic rule to the forwarder.
在步骤a2中，转发器收到用户接入控制面报文，在用户接入控制面报文的报头增加NSH，NSH中SFP指向vBRAS实例，并在NSH的元数据(metadata)部分携带有用户接入端口、逻辑端口以及转发器的信息。In step a2, the forwarder receives the user access control plane message, and adds an NSH to the header of the user access control plane message. The SFP points to the vBRAS instance in the NSH, and carries the user in the metadata part of the NSH. Information about access ports, logical ports, and repeaters.
NSH是用于业务链转发的信息，可以在原有的用户IP报头之外添加NSH。为了灵活控制NSH报文转发，可以采用IP in IP方式添加NSH，使得NSH内层是用户的IP，外层是用于为用户IP报文提供业务的IP。可以通过虚拟可扩展局域网(Virtual Extensible LAN，VXLAN)，或者通用路由封装(Generic Routing Encapsulation，GRE)的封装方式实现上述IP in IP。 NSH is information used for service chain forwarding. You can add NSH in addition to the original user IP header. To flexibly control the forwarding of NSH packets, you can use the IP in IP method to add the NSH so that the inner layer of the NSH is the IP address of the user and the outer layer is the IP used to provide services for the user IP packets. The above IP in IP can be implemented by a virtual Extensible LAN (VXLAN) or a Generic Routing Encapsulation (GRE) encapsulation.
所述转发器还可以为SFC分类器。所述用户接入控制面报文可以包括PPPoE报文、DHCP报文和地址解析协议(Address Reso lution Protocol，ARP)报文等。The repeater can also be an SFC classifier. The user access control plane packet may include a PPPoE packet, a DHCP packet, and an Address Reso Protocol (ARP) packet.
在步骤a3中，用户接入控制面报文通过SFCO到达vBRAS，vBRAS的协议处理模块处理NSH、以太网上点对点协议PPPoE报头或动态主机配置协议DHCP报头，触发用于认证计费的AAA模块与AAA服务器进行通信并发起认证。In step a3, the user access control plane message arrives at the vBRAS through the SFCO, and the protocol processing module of the vBRAS processes the NSH, the peer-to-peer protocol PPPoE header or the dynamic host configuration protocol DHCP header on the Ethernet, and triggers the AAA module and AAA for authentication charging. The server communicates and initiates authentication.
在步骤a4中，AAA服务器认证完成后，vBRAS的协议处理模块响应PPPoE和DHCP等报文完成控制流程。In step a4, after the AAA server is authenticated, the protocol processing module of the vBRAS completes the control flow in response to the packets such as PPPoE and DHCP.
在步骤a5中，控制流程完成后，vBRAS的用户管理模块保存上述步骤中收到的用户互联网协议(Internet Protocol，IP)地址、媒体访问控制(Media Access Control，MAC)地址和PPP会话ID(PPP-Session-ID)等用户信息、用户相关的SFC ID(如SFC1为普通互联网业务，SFC2为家长控制业务，SFC3为视频优化业务)、签约策略(如带宽分配和QoS等信息)以及NSH携带的用户接入端口、逻辑端口以及转发器的信息等。In step a5, after the control flow is completed, the user management module of the vBRAS saves the user's Internet Protocol (IP) address, media access control (MAC) address, and PPP session ID (PPP) received in the above steps. -Session-ID) and other user information, user-related SFC ID (such as SFC1 for common Internet services, SFC2 for parental control services, SFC3 for video optimization services), subscription policies (such as bandwidth allocation and QoS), and NSH User access port, logical port, and information about the repeater.
在步骤a6中，vBRAS的路径管理模块向vBRAS的业务链管理模块查询SFC ID对应的NFP ID及NFP ID的外层封装信息，以将用户流量重定向到二层或三层的外层封装。In step a6, the path management module of the vBRAS queries the service chain management module of the vBRAS for the outer package information of the NFP ID and the NFP ID corresponding to the SFC ID to redirect the user traffic to the outer layer encapsulation of the second or third layer.
vBRAS的业务链管理模块可以通过如下方式获取和维护SFC ID和NFP ID的映射关系：The service chain management module of the vBRAS can obtain and maintain the mapping relationship between the SFC ID and the NFP ID in the following manner:
1)一种方式是，vBRAS和NMS交互，获取SFC ID和NFP ID之间的映射关系，NFP更新时NMS下发通知给vBRAS；1) The method is that the vBRAS and the NMS interact to obtain a mapping relationship between the SFC ID and the NFP ID, and the NMS sends a notification to the vBRAS when the NFP is updated;
2)另一种方式是，vBRAS向控制器查询SFC ID关联的NFP ID及分类器信息。当NFP发生变化时，控制器会将更新后的NEP推送给vBRAS的业务链管理 模块。例如，控制器可以通过NFVO创建NFP时携带SFC ID，从而建立SFC ID和NFP ID的映射关系，也可以通过NMS下发NFP创建请求时，携带SFC ID，从而建立SFC ID和NFP ID的映射关系。再例如，NMS将SFC ID下发给NFVO，NFVO触发控制器创建NFP ID，并建立NFD ID与SFC ID之间的映射关系。或者NMS直接触发控制器创建SFC ID对应的NFP，并配置NFP ID与SFC ID之间的映射关系。2) Another way is that the vBRAS queries the controller for the NFP ID and classifier information associated with the SFC ID. When the NFP changes, the controller will push the updated NEP to the vBRAS service chain management. Module. For example, the controller can carry the SFC ID when the NFP is created by the NFVO, so as to establish the mapping relationship between the SFC ID and the NFP ID, and the SFC ID can be carried by the NMS when the NFP creates the request. . For example, the NMS sends the SFC ID to the NFVO, and the NFVO trigger controller creates an NFP ID and establishes a mapping relationship between the NFD ID and the SFC ID. Or the NMS directly triggers the controller to create an NFP corresponding to the SFC ID and configures a mapping between the NFP ID and the SFC ID.
在步骤a7中，vBRAS的路径管理模块向转发器下发NFP流量规则(rule)和NFP ID，所述NFP流量规则可以包含接入接口、逻辑接口、源MAC地址、IP地址、PPP会话(session)、和VXLAN网络标识(VXLAN Network ldentifier，VNI)中的至少一种信息，用于进行规则匹配。这里，NFP流量规则用于识别用户流量信息，如签约用户、用户设备或用户应用等，外层封装信息包括将用户流量转至下一跳SF的转发信息。在转发器依据NFP流量规则对用户流量进行识别后，可以在用户流量的报文中增加相应的外层封装信息，并转发至下一跳路由，此处的外层封装信息可以包括NFP ID。In step a7, the path management module of the vBRAS sends an NFP traffic rule (rule) and an NFP ID to the forwarder. The NFP traffic rule may include an access interface, a logical interface, a source MAC address, an IP address, and a PPP session. And at least one of VXLAN Network Identifier (VNI) for performing rule matching. Here, the NFP traffic rule is used to identify user traffic information, such as a subscription user, a user equipment, or a user application, and the outer package information includes forwarding information for transferring user traffic to the next hop. After the forwarder identifies the user traffic according to the NFP traffic rule, the outer layer encapsulation information may be added to the packet of the user traffic and forwarded to the next hop route. The outer encapsulation information may include the NFP ID.
在步骤a中，转发器在接收到用户数据面报文之后，根据所述NFP流量规则和NFP ID将所述用户数据面报文转发至已签约的，SFC ID映射的不同NFP。In step a, after receiving the user data plane message, the forwarder forwards the user data plane message to the subscribed, different NFP mapped by the SFC ID according to the NFP traffic rule and the NFP ID.
其中，用户数据报文为用户流量，在与用户签约时，可以为用户分配相应的用户ID和密码，并将该用户所签约的SFD ID等签约信息与该用户进行关联，当用户根据用户ID和密码上线时，PPPoE报文可以携带用户ID和密码对用户进行认证，认证通过后，可以确定用户的IP地址，触发NFP流量规则的下发，使得转发器根据NFP流量规则和NFP ID将用户流量转发至已签约的SFC ID映射的NFP，实现用户流量的转发。The user data packet is user traffic. When signing with the user, the user ID and password can be assigned to the user, and the subscription information such as the SFD ID signed by the user is associated with the user, when the user is based on the user ID. When the password is online, the PPPoE packet can carry the user ID and password to authenticate the user. After the authentication is passed, the user can determine the IP address of the user and trigger the delivery of the NFP traffic rule. The user forwards the user according to the NFP traffic rule and the NFP ID. The traffic is forwarded to the NFP of the contracted SFC ID to forward the user traffic.
本实施例还提供一种网络架构，如图8所示，CPE通过接入网与转发器通信， 转发器通过DC/WAN与自助缴费服务器(自助缴费VNF)通信，转发器在vBRAS的控制下通过不同的业务链，如SFCO、SFC1、SFC2、SFC3和SFC4转发用户流量，vBRAS与AAA***之间具有通信连接，其中，AAA***中包含AAA服务器，自助缴费VNF与为用户提供网上服务的网上营业厅***之间具有通信连接，AAA***分别与支付***和网上营业厅***之间具有通信连接。SFC1向家长控制服务器转发用户流量，转发器通过SFC2向虚拟化路由器转发用户流量，家长控制服务器与虚拟化路由器分别接入因特网。This embodiment further provides a network architecture. As shown in FIG. 8, the CPE communicates with the forwarder through the access network. The repeater communicates with the self-service payment server (self-service payment VNF) through DC/WAN. The forwarder forwards user traffic through different service chains, such as SFCO, SFC1, SFC2, SFC3 and SFC4, under vBRAS control, between vBRAS and AAA system. There is a communication connection, wherein the AAA system includes an AAA server, the self-service payment VNF has a communication connection with the online business hall system for providing online services to the user, and the AAA system has a communication connection with the payment system and the online business hall system respectively.

The NMS applies to the NFVO to dynamically create a self-service payment VNF, and creates a VNFFG corresponding to the SFC4 and an NFP, which may include a path between one or more repeaters and one or more self-service payment VNFs. Among them, the business chain strategy of users who are in arrears will be modified to SFC4.

The vBRAS sends the user information for AAA authentication, and the AAA server returns the user authorization and the SFC ID information related to the service chain policy. The user information may include a MAC address, an IP address, a session ID, or other information carried by the operator in the header of the user packet to prevent fraud, such as an access device ID.
在步骤b3中，vBRAS向控制器查询SFC4对应的NFP ID及外层封装信息。In step b3, the vBRAS queries the controller for the NFP ID and outer package information corresponding to the SFC4.
其中，所述外层封装信息可以是第二层隧道协议(Layer 2 Tunneling Protocol，L2TP)隧道封装的信息。The outer layer encapsulation information may be information encapsulated by a Layer 2 Tunneling Protocol (L2TP) tunnel.
