技术领域Technical field

本发明涉及通信技术，尤其涉及一种网元间链路弹性处理方法及装置。The present invention relates to communications technologies, and in particular, to a link elastic processing method and apparatus between network elements.

背景技术Background technique

网络运营商的传统网络是通过大型的不断增长的专属硬件设备来部署的，具体地，网络运营商的网络是一个数量众多的网元组合起来的非常复杂的网络，网元间的通信一般是通过链路承载。一项新网络服务的推出，通常需要对整个网络的硬件部署以及承载进行大的调整。除此之外，能耗在增加，资本投入存在挑战，又缺少必要的技巧来设计、整合和操作日趋复杂的硬件设备。于是，运营商联盟提出了网络功能虚拟化(Network Function Virtualization，简称NFV)，希望通过标准的信息技术(Information Technology，简称IT)虚拟化技术，把网络设备统一到工业化标准的高性能、大容量的服务器、交换机和存储平台上，该平台可以位于数据中心、网络节点及用户驻地网等。The traditional network of the network operator is deployed through a large and growing number of dedicated hardware devices. Specifically, the network of the network operator is a very complex network composed of a large number of network elements. The communication between the network elements is generally Hosted by the link. The introduction of a new network service usually requires major adjustments to the hardware deployment and bearer of the entire network. In addition, energy consumption is increasing, capital investment is challenging, and the necessary skills are lacking to design, integrate, and operate increasingly complex hardware devices. Therefore, the Carrier Alliance proposed Network Function Virtualization (NFV), hoping to unify network equipment to industrialized standards with high performance and large capacity through standard information technology (IT) virtualization technology. On servers, switches, and storage platforms, the platform can be located in data centers, network nodes, and customer premises networks.

基于NFV技术实现的网络中，每个网元的资源(例如虚拟机个数)是可变的，但是，现有技术中，网元间的链路是在网络设计时规划的，然后在网络部署时由网管手动配置建立，如果要改变链路的数量，必须要重新进行网络规划。In the network implemented by the NFV technology, the resources of each network element (for example, the number of virtual machines) are variable. However, in the prior art, the links between network elements are planned during network design, and then in the network. It is manually configured by the network management system during deployment. If you want to change the number of links, you must re-plan the network.

采用现有技术的话，随着网元的资源变化，可能会造成链路缺失、或者某些链路被闲置而导致资源浪费等问题。With the prior art, as the resources of the network element change, the link may be missing, or some links may be idle, resulting in waste of resources.

图2为本发明提供的网元间链路弹性处理方法实施例一的流程示意图，如图2所示，该方法包括：2 is a schematic flowchart of Embodiment 1 of a method for processing link flexibility between network elements according to the present invention. As shown in FIG. 2, the method includes:

S201、第一网元检测该第一网元的链路负荷参数。S201. The first network element detects a link load parameter of the first network element.

第一网元和第二网元都可以是网络中的任一网元，本实施例中以第一网元为请求方进行撰写，实际实现时，第一网元和第二网元的操作可以互换，只要某个网元有链路弹性变化的需求都可以发起链路弹性变化请求。The first network element and the second network element may be any network element in the network. In this embodiment, the first network element is used as the requesting party for writing. In actual implementation, the operations of the first network element and the second network element are performed. It can be interchanged. As long as a network element has a link elastic change requirement, it can initiate a link elastic change request.

上述链路负荷参数可以包括下述任一项或其组合：链路占用率、链路处理的中央处理器(Central Processing Unit，简称CPU)占用率、链路处理的内存占用率、是否接收到链路弹性变化的业务诉求等。The link load parameter may include any one of the following or a combination thereof: link occupancy rate, central processing unit (CPU) occupancy rate of the link processing, memory usage of the link processing, and whether it is received.

S202、第一网元在上述第一网元的链路负荷参数满足预设条件时，在第一链路上向第二网元发送链路弹性变化请求，用于与该第二网元协商弹性变化该第一网元和第二网元之间的链路。 S202. The first network element sends a link elastic change request to the second network element to negotiate with the second network element, when the link load parameter of the first network element meets the preset condition. The link between the first network element and the second network element is elastically changed.

第一网元或者MANO会根据链路负荷参数所体现的链路实际情况，触发第一网元与第二网元协商增加或减少链路数量。第一网元和第二网元通过链路弹性变化请求协商弹性变化该第一网元和第二网元之间的链路。The first network element or the MANO triggers the first network element to negotiate with the second network element to increase or decrease the number of links according to the actual link condition reflected by the link load parameter. The first network element and the second network element elastically change the link between the first network element and the second network element by using a link elastic change request negotiation.

S203、第二网元根据该链路弹性变化请求确定同意该链路弹性变化请求，并在上述第一链路上向第一网元发送链路弹性变化响应。S203. The second network element determines to agree to the link elastic change request according to the link elastic change request, and sends a link elastic change response to the first network element on the first link.

第二网元接收到链路弹性变化请求后，先判断该链路弹性变化请求是否合法，例如判断该请求的消息格式是否合法，请求中携带的相关信息是否合法等，如果不合法，则向第一网元回复响应，在响应中携带响应失败标识(NOK)；如果合法，则第二网元确定同意上述链路弹性变化请求，在上述第一链路上向第一网元发送链路弹性变化响应，表示第一网元与第二网元协商成功，执行S204，进行实际的链路弹性变化操作，即完成链路的增加或减少，这些弹性变化的链路均为业务链路。After receiving the link elastic change request, the second network element first determines whether the link elastic change request is legal, for example, determining whether the requested message format is legal, whether the related information carried in the request is legal, and the like, if not, The first network element replies with a response, and carries a response failure identifier (NOK) in the response; if it is legal, the second network element determines to agree to the link elastic change request, and sends a link to the first network element on the first link. The elastic change response indicates that the first network element and the second network element negotiate successfully, and S204 is performed to perform an actual link elastic change operation, that is, the link is increased or decreased, and the elastically changed links are all service links.

S204、第一网元接收第二网元在上述第一链路上发送的链路弹性变化响应，并根据该链路弹性变化响应向第二网元发起链路弹性变化操作请求，以完成第一网元和第二网元之间的链路弹性变化。S204: The first network element receives a link elastic change response sent by the second network element on the first link, and initiates a link elastic change operation request to the second network element according to the link elastic change response, to complete the The link elasticity between a network element and the second network element changes.

具体地，第一网元接收到第二网元在上述第一链路上发送的链路弹性变化响应，说明协商成功，则开始实际的增加或减少链路的操作，即发起链路弹性变化操作请求，第二网元响应该链路弹性变化操作请求，与第一网元一起进行链路弹性变化操作。Specifically, the first network element receives the link elastic change response sent by the second network element on the first link, indicating that the negotiation succeeds, and then actually increases or decreases the link operation, that is, initiates the link elastic change. The operation request, the second network element responds to the link elastic change operation request, and performs a link elastic change operation together with the first network element.

本实施例中，第一网元在上述第一网元的链路负荷参数满足预设条件时，在第一链路上向第二网元发送链路弹性变化请求，与该第二网元协商弹性变化该第一网元和第二网元之间的链路，第二网元如果同意链路弹性变化请求，则发送链路弹性变化响应，表示协商成功，则第一网元和第二网元进一步完成链路弹性变化操作，实现第一网元和第二网元之间的链路弹性变化，从而实现了网元之间的链路可以根据实际需要弹性变化，避免由于网元的资源变化而导致链路资源的缺乏或浪费的问题。In this embodiment, when the link load parameter of the first network element meets the preset condition, the first network element sends a link elastic change request to the second network element on the first link, and the second network element The negotiation elastically changes the link between the first network element and the second network element. If the second network element agrees to the link elastic change request, the second network element sends a link elastic change response, indicating that the negotiation succeeds, and the first network element and the first network element The second network element further completes the link elastic change operation, and implements the link elastic change between the first network element and the second network element, so that the link between the network elements can be flexibly changed according to actual needs, and the network element is avoided. The problem of resource loss leads to the lack or waste of link resources.

具体实施过程中，上述第一链路可以是专用的链路管理通道，该链路管理通道专用于第一网元和第二网元进行链路弹性变化的协商。链路管理通道可以是在网络设计时就部署好的，具体实施时有管理员手动添加，也可以是图1中的Orchestrator在构建网络服务(Network Service)过程中建立网元时，直接增加网元间的链路管理通道，但并不以此为限。In a specific implementation, the foregoing first link may be a dedicated link management channel, and the link management channel is dedicated to the first network element and the second network element to perform link elastic change negotiation. The link management channel can be deployed at the time of network design. In the specific implementation, an administrator manually adds it, or the Orchestrator in Figure 1 directly adds a network when establishing a network element in the process of constructing a network service (Network Service). Link management channel between meta-, but not limited to this.

具体实现过程中，也可以在第一网元和MANO之间建立链路管理通道，并在第二网元和MANO之间建立链路管理通道，由MANO作为第一网元和第二网元之间的中转站，即第一网元和第二网元协商过程中的消息都先发给MANO，由MANO为双方转发。In the specific implementation process, a link management channel may be established between the first network element and the MANO, and a link management channel is established between the second network element and the MANO, and the MANO is used as the first network element and the second network element. The transfer station between the first network element and the second network element is sent to MANO first, and MANO forwards it to both parties.

另一实施例中，第一链路也可以为已有的业务承载链路。In another embodiment, the first link may also be an existing service bearer link.

需要说明的是，一种情况下：上述第一网元在上述第一网元的链路负荷参数满足预设条件时，在第一链路上向第二网元发送链路弹性变化请求，可以是：第一网元自己判断第一网元的链路负荷参数是否满足预设条件，若满足，则在第一链路上向第二网元发送链路弹性变化请求。It should be noted that, in one case, the link load parameter of the first network element in the first network element meets a preset. If the condition is met, the first network element determines whether the link load parameter of the first network element meets the preset condition, and if yes, the first network element determines whether the link load parameter of the first network element meets the preset condition. A link elastic change request is sent to the second network element on the first link.

另一种情况下，上述第一网元在上述第一网元的链路负荷参数满足预设条件时，在第一链路上向第二网元发送链路弹性变化请求，可以是：第一网元将上述第一网元的链路负荷参数发送给MANO，MANO在第一网元的链路负荷参数满足预设条件时向第一网元发送链路弹性变化指示，第一网元根据链路弹性变化指示在第一链路上向第二网元发送链路弹性变化请求，即第一网元根据链路弹性变化指示与第二网元协商进行链路弹性变化。In another case, when the link load parameter of the first network element meets the preset condition, the first network element sends a link elastic change request to the second network element on the first link, which may be: A network element sends the link load parameter of the first network element to the MANO, and the MANO sends a link elastic change indication to the first network element when the link load parameter of the first network element meets the preset condition, and the first network element The link elastic change request is sent to the second network element according to the link elastic change indication, that is, the first network element negotiates with the second network element to perform link elastic change according to the link elastic change indication.

At the same time, the same identifier is carried in the response, and then the requested network element can receive a response to which request is made when the response is received. If the number of links to be built is not included in the link setup request, the default number is 1, but not limited to this.

If the link establishment request is legally determined, the second network is established for the link establishment. The device also needs to apply for a resource to the NFVI, that is, to apply for a virtual machine, an IP address, a port number, and the like. After the application is successful, a link establishment response is sent to the first network element on the first link.

If you do not agree, you can only carry the transaction identifier and rejection identifier (NOK) used to identify the current link request in the response. Other embodiments can be performed as such.
