Description

虚拟网络业务的提供方法及***Method and system for providing virtual network service 技术领域Technical field
本发明涉及通信领域，具体而言，涉及一种虚拟网络业务的提供方法及***。The present invention relates to the field of communications, and in particular to a method and system for providing virtual network services.
背景技术Background technique
在数据中心中，如何提供虚拟网络(Virtual Network，简称为VN)一直都是一个热门的话题，涉及到网络的虚拟化等众多方面，引起设备供应商和运营商的多方关注。例如，在互联网工程任务组(Internet Engineering Task Force，简称为IETF)中专门成立了一个工作组的基于层三的网络虚拟化(Network Virtualization OverL3，简称为NVO3)对其进行研究。虽然，经过2年多的讨论，对具体如何实现VN的提供，虽然有一些讨论，以及大致的方向，如图1所示，NVO3确定了虚拟网络提供的架构。In the data center, how to provide a virtual network (Virtual Network, VN for short) has always been a hot topic, involving many aspects such as virtualization of the network, causing concern from equipment suppliers and operators. For example, in the Internet Engineering Task Force (IETF), a working group's Network Virtualization OverL3 (NVO3) was established. Although, after more than two years of discussion, there are some discussions and general directions on how to implement VN. As shown in Figure 1, NVO3 determines the architecture provided by the virtual network.
图1是相关技术中NVO3的体系结构网络示意图，如图1所示，有一个集中的网络虚拟化控制设备(Network Virtualization Authority，简称为NVA)，实现对业务提供的控制，VN中的多个虚拟机(Virtual Machine，简称为VM)连接到网络虚拟化边缘(Network Virtualization Edge，简称为NVE)，并进一步与NVE中的该VN的虚拟路由转发(Virtual Route Forwarding，简称为VRF)进行关联，多个不同NVE中的同一VN的不同的VRF，通过NVE直接的重叠网络隧道实现连接，从而实现VN。当然，VN可以通过NVE(一般驻留在数据中心网关)和互联网实现连接。图1中并没有显示。FIG. 1 is a schematic diagram of an architecture network of NVO3 in the related art. As shown in FIG. 1 , a centralized network virtualization control device (NVA) is implemented to implement control of service provision, and multiple in the VN. A virtual machine (Virtual Machine, referred to as a VM) is connected to a Network Virtualization Edge (NVE), and is further associated with a Virtual Route Forwarding (VRF) of the VN in the NVE. Different VRFs of the same VN in a plurality of different NVEs are connected through an NVE direct overlapping network tunnel, thereby implementing VN. Of course, the VN can be connected via NVE (typically residing in the data center gateway) and the Internet. It is not shown in Figure 1.
但对具体的解决方案，现有技术中并没有提出统一的技术方案，虽然有部分厂家也提出了解决思路，但是，其存在缺陷非常明显，在技术选择方面，也存在很多问题。However, for the specific solution, the prior art does not propose a unified technical solution. Although some manufacturers have also proposed solutions, the defects are very obvious, and there are also many problems in technology selection.
并且，现有技术中，目前的讨论主要还是基于手工配置的实现：一般是通过人工收集VN用户的需求，并由网络管理员将给需求分解映射到相关的虚拟机监督/管理程序(Virtual Machine Monitor，简称为VMM)和NVE设备，再通过配置这个设备，从而实现VN业务的提供。Moreover, in the prior art, the current discussion is mainly based on the implementation of manual configuration: generally by manually collecting the requirements of the VN user, and the network administrator will map the demand decomposition to the relevant virtual machine supervision/management program (Virtual Machine) Monitor, referred to as VMM) and NVE devices, and then configure this device to provide VN services.
现有技术中也已经进一步使用门户网站来收集VN用户的需求，这样减少了人工的干预，提高了效率。在收集完需求后，其还是需要网络管理员根据这个需求，来进行手工配置，完成业务的提供。 The portal has also been further used in the prior art to collect the needs of VN users, which reduces manual intervention and improves efficiency. After collecting the requirements, it still needs the network administrator to manually configure and complete the service according to this requirement.
针对相关技术中，对于VN业务需求进行手工配置而导致的工作量大、耗时长以及容易出错的问题，尚未提出有效的解决方案。In the related art, an effective solution has not been proposed for the problem of large workload, long time, and error prone caused by manual configuration of VN service requirements.

为了更加全面详细的理解本发明实施例以及优选实施例中的技术方案，以下结合优选实施例进行说明：In order to more fully understand the technical solutions in the embodiments of the present invention and the preferred embodiments, the following description is described in conjunction with the preferred embodiments:
优选实施例一 Preferred embodiment 1
在本优选实施例一中，模拟现有网络管理配置机制的自动部署方案In the preferred embodiment 1, an automatic deployment scheme simulating an existing network management configuration mechanism
图8为根据本发明优选实施例一的VN业务需求的自动提供示意图，如图8所示：FIG. 8 is a schematic diagram of automatic provisioning of VN service requirements according to a preferred embodiment of the present invention, as shown in FIG. 8:
本发明优选实施例一的基本的实现思路是，根据VN的站点分布，连接带宽，VM的能力指标，等等VN的需求信息，根据网络资源的可用情况，以及部署是否合理等因素，综合考虑实现VN需求到运营商承载网/基础结构设施的映射，即运营商如何选择一组相关的NVE和VM来实现该VN。The basic implementation idea of the preferred embodiment 1 of the present invention is to comprehensively consider the VN site information, the connection bandwidth, the VM capability index, and the VN requirement information according to the availability of the network resources and whether the deployment is reasonable. The mapping of the VN requirements to the carrier bearer network/infrastructure facilities is implemented, that is, how the operator selects a group of related NVEs and VMs to implement the VN.
对于如何确定VN的具体映射，需要自动地将实现VN的有关的配置管理命令及相关的参数信息等，发送给有关VMM/VM协同***和NVE，VMM/VM协同***和NVE执行这些配置管理命令，从而实现VN的自动提供。For how to determine the specific mapping of the VN, it is necessary to automatically send the relevant configuration management commands and related parameter information for implementing the VN to the VMM/VM collaborative system and the NVE, and the VMM/VM collaborative system and the NVE execute these configuration management commands. In order to achieve automatic provision of VN.
需要进一步说明的是，对NVA直接发送给VM协同***的命令，可能与直接发送给VMM的命令是不一样的，例如包括VN中的VM的个数，VM的性能参数和组成VN所需要的有关参数，例如接入NVE的位置等等，VM协同***根据VN的需求信息和现有可用资源的情况，发送进一步的命令到VMM、具体的部署VM，相关的VMM在部署好VM后，将部署结果反馈给VM协同***，在VM协同***完成了VN的所有VM部署后，将部署的结果信息，包括：VM的个数，位置，和接口配置等信息反馈给NVA，由NVA进一步协调确定最终的VN部署，即各VM和NVE的具***置和有关参数，以及最终的部署完成。而由NVA直接发送给VMM的命令，是已经确定了具体的VM的位置了的，就不需要有关的位置信息。 It should be further noted that the command sent directly to the VM cooperative system by the NVA may be different from the command sent directly to the VMM, for example, including the number of VMs in the VN, performance parameters of the VM, and required components constituting the VN. Related parameters, such as the location of accessing the NVE, etc., the VM collaboration system sends further commands to the VMM and the specific deployment VM according to the VN requirement information and the existing available resources. After the VM is deployed, the relevant VMM will The result of the deployment is fed back to the VM collaboration system. After the VM collaboration system completes all VM deployments of the VN, the result information of the deployment, including the number of VMs, location, and interface configuration, is fed back to the NVA, which is further coordinated by the NVA. The final VN deployment, ie the specific location and associated parameters of each VM and NVE, and the final deployment is complete. The command sent directly by the NVA to the VMM is that the location of the specific VM has been determined, and no relevant location information is needed.
需要说明的是，VM协同***也可以使用其专有协议，将所述VN的VM需要发送给具体部署VM的VMM，从而实现VM部署。It should be noted that the VM collaboration system can also use its proprietary protocol to send the VM of the VN to the VMM of the specific deployment VM, thereby implementing VM deployment.
当然，发送给VM协同***的命令也可以是向单独发送给VMM一样，是一些独立的VM配置管理命令。Of course, the commands sent to the VM collaboration system can also be sent to the VMM separately, as are some separate VM configuration management commands.
需要说明的是，目前的VMM和NVE设备，还不能通过SNMP或者NETCONF等协议机制，自动实现VN的部署，即还需要通过对这些管理协议进行接口的标准化，才能实现，而这个工作是一个非常复杂的过程，在必要的情况下，其还会需要一个时间非常长的标准定义过程，从而会严重影响VN业务的开展。It should be noted that the current VMM and NVE devices cannot automatically implement VN deployment through protocol mechanisms such as SNMP or NETCONF. That is, it is necessary to standardize the interfaces of these management protocols, and this work is very The complex process, if necessary, will also require a very long standard definition process, which will seriously affect the development of the VN business.
综上所述，本发明实施例是针对VN的自动提供的技术方案，设计一个针对NVE/VMM/VM协同***和NVA之间的接口协议，实现具体针对VN提供的有关命令和协议，在具体实施过程中，能够相对简单的实现VN业务自动提供。In summary, the embodiment of the present invention is directed to an automatic solution of the VN, and designs an interface protocol between the NVE/VMM/VM collaborative system and the NVA, and implements specific commands and protocols specific to the VN. During the implementation process, the VN service can be automatically provided relatively simply.
具体的，上述实施例中的接口协议可以是VNTP协议(如图9所示)，通过该协议的报头信息中的命令/操作码字段定义有关与VN自动提供有关的命令，并通过VNTP报文的数据部分定义相关配置管理命令的有关参数信息，从而可以实现VN的自动提供。Specifically, the interface protocol in the foregoing embodiment may be a VNTP protocol (as shown in FIG. 9), and the command/opcode field in the header information of the protocol defines a command related to automatic provisioning of the VN, and the VNTP message is passed. The data part defines the relevant parameter information of the relevant configuration management command, so that the automatic provision of the VN can be realized.
图9是VNTP的命令格式，可以通过TCP，UDP，或者直接通过IP等多种协议进行传输。具体的配置管理命令由操作码字段进行定义。需要说明的是，这些字段的名称只是一种表示，并不影响本发明的实质内容，例如操作码字段，也可以命名为命令字段。进一步需要说明的是，图9只是显示了一些必要的字段，还可以进行有关字段的扩展，例如增加更多的字段，根据业务开展的需要，例如可以在操作码字段前增加一个版本字段，用于指示VNTP协议的版本，因为VNTP协议本身也可能在不断的发展过程中，需要由新的版本号，来指示协议本身的演进和具有不同的特征。Figure 9 shows the VNTP command format, which can be transmitted over TCP, UDP, or directly over multiple protocols such as IP. The specific configuration management commands are defined by the opcode field. It should be noted that the names of these fields are only a representation and do not affect the essence of the present invention, such as an opcode field, and may also be named as a command field. It should be further noted that FIG. 9 only shows some necessary fields, and can also expand related fields, for example, adding more fields. For example, a version field may be added before the opcode field according to the needs of the business development. Indicating the version of the VNTP protocol, because the VNTP protocol itself may be in the process of continuous development, a new version number is required to indicate the evolution of the protocol itself and have different characteristics.
在本发明实施例中，还可以执行以下技术方案：NVA向特定VN的所有NVE发送有关的配置管理命令。具体的，包括：VN生成/产生命令及有关VN上下文context信息，NVE在收到该命令后，自动在NVE中生成对应的VN，有关的参数信息或者context信息，包括VN的VRF，VN-ID，VN名称，或者包括有关隧道封装信息等。In the embodiment of the present invention, the following technical solution may also be implemented: the NVA sends relevant configuration management commands to all NVEs of a specific VN. Specifically, the VN generates/generates a command and the context information about the VN context. After receiving the command, the NVE automatically generates a corresponding VN in the NVE, and the related parameter information or context information, including the VN of the VN, and the VN-ID. , VN name, or include information about tunnel encapsulation.
上述配置管理命令还可以包括VN删除命令，在VN结束提供，或者VN的配置发生改变时，例如迁移到其他NVE，删除NVE中的VN信息。 The configuration management command may also include a VN deletion command, and when the VN is terminated, or when the configuration of the VN is changed, for example, to another NVE, the VN information in the NVE is deleted.
为了实现VN的自动提供，上述配置管理命令还可以包括：VN修改命令，用于增加VN的接口，或者VN相关的其他信息，其中，上述修改命令，可以用于修改VN的接口的QoS设置，以及如果接口上运行路由协议，可以修改路由参数等。进一步，上述配置管理命令中还可以进一步支持更多的功能，例如，可以启动NVE中与VN的功能有关的功能，例如对VN的私有IP地址转换成可以访问公共网络的公用IP地址的NAT功能。或者配置防火墙，或者负载均衡器等功能，和配置有关的参数等。In order to implement the automatic provisioning of the VN, the configuration management command may further include: a VN modification command, which is used to add an interface of the VN, or other information related to the VN, where the modification command may be used to modify the QoS setting of the interface of the VN. And if the routing protocol is running on the interface, you can modify the routing parameters and so on. Further, the above configuration management command may further support more functions, for example, functions related to the function of the VN in the NVE, for example, converting the private IP address of the VN into a NAT function capable of accessing the public IP address of the public network. . Or configure the firewall, or load balancer and other functions, and configuration related parameters.
需要说明的是，执行完相关的命令后，NVE返回结果给NVA。这个也是通过VNTP的特定命令实现。It should be noted that after executing the relevant commands, the NVE returns the result to the NVA. This is also done through specific commands of VNTP.
当然，为保证业务提供的安全性，NVE需要对NVA的命令进行认证，一种可以实现的方法是每个这样的命令报文，都携带支持双向认证的消息。这个是现有技术，只需要NVTP的报文，提供相关的信息承载支持即可。Of course, in order to ensure the security of the service, the NVE needs to authenticate the NVA commands. One method that can be implemented is that each such command message carries a message supporting the two-way authentication. This is a prior art technology. Only NVTP packets are required, and related information bearer support is provided.
需要进一步说明的是，一般情况下VN都包括若干VM通过一个或者多个NVE组成的网络，但是也有特殊的VN，它不需要VM，只需要将不同的站点网络连接在一起，在这种情况下，本发明的方法也可以实现该类VN的自动部署，而且相对比较简单，只需将VN的需求映射到有关的NVE即可，而不涉及VM的映射，并进一步通过前述的过程实现具体NVE的配置，从而实现VN的自动部署。It should be further noted that in general, a VN includes a network of several VMs through one or more NVEs, but there is also a special VN that does not require a VM and only needs to connect different site networks together. The method of the present invention can also implement automatic deployment of the VN of the type, and is relatively simple, and only needs to map the requirements of the VN to the relevant NVE, without involving the mapping of the VM, and further implements the specific process by the foregoing process. NVE configuration, which enables automatic deployment of VN.
优选实施例二Preferred embodiment two
基于NVE自动发现协议的自动部署方案Automatic deployment scheme based on NVE automatic discovery protocol
NVA在获得VN需求后，首先获得VM的详细的需求信息，上述需求信息包括VM的个数，VM的性能指标等参数，并将对VM的详细需求信息发送给VM协同***。由VM协同***完成所有相关的VM到具体的VMM的分布和部署。其中VM的部署，需要包括对NVE自动发现协议的支持，同时，可以规定在VM准备就绪后，自动触发NVE自动发现协议的执行。当然，也可以通过NVA发送显式的VM开始运行NVE自动发现协议命令，触发VM的NVE自动发现协议的运行。After obtaining the VN requirement, the NVA first obtains the detailed requirement information of the VM. The foregoing requirement information includes parameters such as the number of VMs, the performance indicators of the VM, and the detailed requirement information of the VM is sent to the VM collaboration system. The distribution and deployment of all relevant VMs to specific VMMs is done by the VM collaboration system. The deployment of the VM needs to include support for the NVE auto-discovery protocol. At the same time, it can be specified to automatically trigger the execution of the NVE auto-discovery protocol after the VM is ready. Of course, the NVE automatic discovery protocol command can also be started by sending an explicit VM through the NVA, triggering the operation of the VM's NVE automatic discovery protocol.
需要说明的是，本实施例的有关VM的部署，如果不使用VM协同***，NVA也可以直接将VN需求的VM映射到具体的VMM，根据VMM的资源情况以及和NVE的连接位置等信息。具体的配置管理命令和有关参数的传递情况，使用前述类似/相同的机制。 It should be noted that, in the deployment of the VM in this embodiment, if the VM collaboration system is not used, the NVA can directly map the VMs required by the VN to a specific VMM, according to information about the resources of the VMM and the connection location of the NVE. The specific configuration management commands and the transfer of related parameters use the similar/identical mechanism described above.
上述VM的自动发现NVE协议的执行，触发一系列事件，包括：VM自动发送NVE自动报文，以发现NVE，在确认为其服务的NVE后，由NVE自动发送VM的VN身份认证，在身份认证通过后，获得VM所在VN的context信息，并返回给NVE；上述NVE自动配置生成VN context，上述配置工作，包括但不限于：生成VRF和/或生成VRF的有关表项。上述VRF表项包括但不限于：IP/MAC地址，接口，VN-ID，NVE地址之一或者多个。在上述NVE生成VN context后，或者进一步生成新的VRF表项信息后，自动发送VN更新信息，使得VN的路由信息的同步。The automatic discovery of the NVE protocol of the VM triggers a series of events, including: the VM automatically sends an NVE automatic message to discover the NVE. After confirming the NVE served by the NVE, the NVE automatically sends the VN identity authentication of the VM. After the authentication is passed, the context information of the VN of the VM is obtained and returned to the NVE. The NVE automatically configures the VN context to generate the VN context. The foregoing configuration includes, but is not limited to, generating a VRF and/or generating a VRF related entry. The above VRF entries include, but are not limited to, one or more of an IP/MAC address, an interface, a VN-ID, and an NVE address. After the VVE context is generated by the NVE, or after the VRF entry information is further generated, the VN update information is automatically sent to synchronize the routing information of the VN.
需要说明的是，在本实施例的具体环境中，并不假设NVE已经获得了NVA的地址。即在一般的情况下，NVE并不自动拥有NVA的地址信息，需要通过某种方法来获得，一种方法是通过手工配置NVA的地址。但是，这个并不符合业务自动提供的宗旨。而且，NVE的数量一般都比较庞大，要进行手工配置是一个耗时的工作。因此，需要有自动发现的方案，支持VN的自动提供，对于该技术方案，优选实施例三提供了详细的技术方案。It should be noted that, in the specific environment of the embodiment, it is not assumed that the NVE has obtained the address of the NVA. That is, in the general case, the NVE does not automatically own the address information of the NVA, and needs to be obtained by some method. One method is to manually configure the address of the NVA. However, this does not meet the purpose of the business automatically provided. Moreover, the number of NVEs is generally large, and manual configuration is a time consuming task. Therefore, there is a need for an automatic discovery scheme to support automatic provisioning of the VN. For the technical solution, the preferred embodiment 3 provides a detailed technical solution.
图10为根据本发明优选实施例二的VN自动提供流程图，如图10所示：FIG. 10 is a flow chart of automatically providing a VN according to a preferred embodiment of the present invention, as shown in FIG.
需要说明的是，图10中的AAA是认证授权计费(Authentication、Authorization and Accounting)的简称。It should be noted that the AAA in FIG. 10 is an abbreviation of Authentication, Authorization and Accounting.
步骤S902：准备VN的VM，以及其所属的VN信息。具体的是，通过门户***获得VN的需求并将VN需求发送给NVA，或者通过网络管理员将VN的需求配置进NVA，由NVA进一步将VN需求映射到有关相关的NVE和VMM/VM协同***，并由VM协同***准备好各VM，所述VM支持NVE自动发现协议；Step S902: Prepare the VM of the VN, and the VN information to which it belongs. Specifically, the VN requirement is obtained through the portal system and the VN requirement is sent to the NVA, or the VN requirement is configured into the NVA through the network administrator, and the VN requirement is further mapped by the NVA to the relevant NVE and VMM/VM collaborative system. And each VM is prepared by the VM collaboration system, and the VM supports the NVE automatic discovery protocol;
步骤S904：VM就绪后，或者通过显示命令触发VM运行VN自动发现协议；Step S904: After the VM is ready, or by triggering the display command to trigger the VM to run the VN automatic discovery protocol;
步骤S906：VM发送NVE发现广播报文；Step S906: The VM sends an NVE discovery broadcast message.
步骤S908：NVE返回应答存在信息；Step S908: The NVE returns the response existence information.
步骤S910：VM发送NVE请求报文；Step S910: The VM sends an NVE request message.
步骤S912：NVE返回确认信息；Step S912: The NVE returns confirmation information.
步骤S914：NVE自动发现NVA，并通过NVA实现对VM接入VN的身份认证，可选地获取VM的IP地址； Step S914: The NVE automatically discovers the NVA, and implements identity authentication for accessing the VN by the NVA, and optionally obtains an IP address of the VM.
步骤S916：NVA/AAA向NVE返回VN的相关信息，所述相关信息是VN context的部分，或者全部组成信息。其中包括所述VN是层2(L2)的，还是层3(L3)网络信息。Step S916: The NVA/AAA returns information about the VN to the NVE, where the related information is part of the VN context, or all of the composition information. This includes whether the VN is Layer 2 (L2) or Layer 3 (L3) network information.
步骤S918：NVE向VM返回VN-ID信息；Step S918: The NVE returns VN-ID information to the VM;
步骤S920：NVE形成对应VN转发表的VM对应的表项；VRF表项包括但不限于：IP/MAC地址，接口，虚拟网络号/标识。Step S920: The NVE forms an entry corresponding to the VM corresponding to the VN forwarding table. The VRF entry includes but is not limited to: an IP/MAC address, an interface, and a virtual network number/identification.
步骤S922：NVE通过NVE-NVA协议进行VN信息同步；具体的，NVE可以通过VNTP协议自动地同步VN的其他NVE的路由信息。即将本地的路由信息，或者是新更新的路由信息，通过NVA同步到VN中的其他所有NVE中。而不同VN的路由信息的通告，通过VN-ID来进行区分，从而不至于发生不同VN之间的路由更新发生错误。Step S922: The NVE performs VN information synchronization through the NVE-NVA protocol. Specifically, the NVE can automatically synchronize routing information of other NVEs of the VN through the VNTP protocol. The local routing information or the newly updated routing information is synchronized to all other NVEs in the VN through the NVA. The advertisement of the routing information of different VNs is distinguished by the VN-ID, so that the routing update between different VNs does not occur.
步骤S924：VM发送报文；报文封装可选的使用VN-ID，或者进一步通过指定的L2协议进行封装，例如包括VLAN封装，或者Q-in-Q封装等。Step S924: The VM sends a message; the packet encapsulation is optionally using a VN-ID, or further encapsulated by using a specified L2 protocol, for example, including VLAN encapsulation, or Q-in-Q encapsulation.
步骤S926：NVE发送报文到其他NVE；一般通过VN-ID进行封装区分不同的VN。Step S926: The NVE sends the message to the other NVEs; generally, the VN-ID is encapsulated to distinguish different VNs.
步骤S928：目的VNE发送报文给所属VN的VM；Step S928: The destination VNE sends a message to the VM of the VN to which it belongs.
步骤S930：可以作为目的端NVE从其他NVE接收报文。Step S930: The message can be received from other NVEs as the destination end NVE.
对上述步骤，有关报文转发，进一步描述如下，VM发送报文，一般包括VLAN信息。而NVE通过设定的VLAN接口接收该报文，并和相关的VN进行对应，具体的是根据报文的目的IP地址查找VRF的有关表项，获得目的地址的所对应的NVE地址，对原IP报文，用NVE的IP地址作为源地址，目的NVE的IP地址作为目的地址，并进一步使用VN-ID对原IP报文进行封装并发送。即实现重叠网络的报文传送。在该报文到达目的NVE后，目的NVE根据VN-ID信息，将上述报文交由上述VN的VRF进行处理，具体的，是根据目的IP地址查找VRF表项，获得对应的接口，并将该报文发送到该接口上去，一般而言，需要进行L2层封装，目的VM接收经过L2封装的报文，并解封装出原来的IP报文。从而实现通信。从而实现了VN。For the above steps, the packet forwarding is further described as follows. The VM sends a packet, which generally includes VLAN information. The NVE receives the packet through the set VLAN interface and corresponds to the related VN. Specifically, the VRF entry is searched according to the destination IP address of the packet, and the corresponding NVE address of the destination address is obtained. For the IP packet, the IP address of the NVE is used as the source address, and the IP address of the destination NVE is used as the destination address. The original IP packet is further encapsulated and sent by using the VN-ID. That is, the message transmission of the overlapping network is realized. After the packet arrives at the destination NVE, the destination NVE processes the packet to the VRF of the VN according to the VN-ID information. Specifically, the VRF entry is searched according to the destination IP address, and the corresponding interface is obtained. The packet is sent to the interface. In general, the L2 layer encapsulation is required. The destination VM receives the L2 encapsulated packet and decapsulates the original IP packet. Thereby achieving communication. Thereby achieving VN.
而本实施例的步骤S914的自动发现方法，见优选实施例三。 For the automatic discovery method of step S914 of this embodiment, see the third embodiment.
优选实施例三Preferred embodiment three
NVE的NVA自动发现的实现方法NVE NVA automatic discovery implementation method
对于NVA的自动发现，由于网络中的NVA数量一般都比较有限，例如逻辑上只有一个NVA，或者少数的几个NVA，因此，一种NVE自动发现NVA实现方法，是：在NVA发送给VMM/VM协同***或者NVE的配置信息中，包括NVA的地址信息，或者针对NVE自动发现协议，即优选实施案例二的情况，是从VM的NVE自动发现协议消息中获得NVA信息，包括NVA的地址信息，而该信息进一步是有最初的NVA准备VM的命令中提供的。For the automatic discovery of NVA, since the number of NVAs in the network is generally limited, for example, there is only one NVA logically, or a few NVAs, an NVE automatic discovery NVA implementation method is: sending to the VMM/ in the NVA. The configuration information of the VM collaboration system or the NVE, including the address information of the NVA, or the NVE automatic discovery protocol, that is, the case of the preferred implementation case 2, is to obtain the NVA information, including the address information of the NVA, from the NVE automatic discovery protocol message of the VM. And the information is further provided in the initial NVA preparation VM command.
这样，就可以免除需要对每一个NVE配置NVA信息。In this way, it is possible to dispense with the need to configure NVA information for each NVE.
由于可能支持VN客户漫游的情况，即可能存在多个不同的运营商的NVA，因此NVA的信息，可能不是一个NVA的IP地址，而是一组NVA IP地址，表示有多个NVA。而且NVE可以进一步根据NVA地址的不同运营商属性，在具体的VN提供过程中进行选择。Since the VN client roaming may be supported, that is, there may be multiple NVAs of different operators, the NVA information may not be an NVA IP address, but a set of NVA IP addresses, indicating that there are multiple NVAs. Moreover, the NVE can further select in a specific VN providing process according to different operator attributes of the NVA address.
在NVE的操作中，可以根据VN客户的属性，选择一个适合于VN的NVA。当然，在这种情况下，NVE使用NVA时，首先需要通过NVA的认证，对漫游用户需要和其归属的NVA进行进一步的通信并获得认证通过，才可以获得业务提供。In the operation of the NVE, an NVA suitable for the VN can be selected according to the attributes of the VN client. Of course, in this case, when the NVE uses the NVA, it first needs to be authenticated by the NVA, and the roaming user needs to further communicate with the NVA to which it belongs and obtain the authentication pass before the service provision can be obtained.
本实施例的另外一种实现方案是NVE可以通过SLP协议发现NVA，或者NVA也可以使用SLP自动发现NVE。Another implementation of this embodiment is that the NVE can discover the NVA through the SLP protocol, or the NVA can also automatically discover the NVE using the SLP.
具体的实现方案是：SLP协议主要包括UA(用户代理)，SA(服务代理)，和DA(目录代理)等几个部分，UA通过SA或者/和DA获得业务的具***置。在本实施例的应用中，SA和/或者DA中保存的是NVA和/或者NVE的地址，NVA或者NVE通过SLP协议获得NVE或者NVA的地址。具体的，在网络中部署一个SA和/或DA目录服务器，所有有关的NVE等可以提供VN支持的设备，在加电后或者在SLP协议启动后，向上述SA和/或DA服务目录服务器注册。并且，SA和/或DA服务目录服务器，可以接受对目录服务的查询，这样NVA/NVE就是通过这样的机制，来实现NVE/NVA的自动发现。The specific implementation scheme is that the SLP protocol mainly includes UA (User Agent), SA (Service Agent), and DA (Directory Agent), and the UA obtains the specific location of the service through the SA or/and the DA. In the application of this embodiment, the addresses of the NVA and/or the NVE are stored in the SA and/or the DA, and the NVA or NVE obtains the address of the NVE or the NVA through the SLP protocol. Specifically, an SA and/or DA directory server is deployed in the network, and all related NVEs and the like can provide VN-supported devices, and register with the SA and/or DA service directory server after power-on or after the SLP protocol is started. . Moreover, the SA and/or DA service directory server can accept queries for the directory service, so that NVA/NVE implements automatic discovery of NVE/NVA through such a mechanism.
