Description

The present invention relates to the field of communications, and in particular to a service processing method and apparatus between service nodes. BACKGROUND With the large-scale popularization of broadband networks, the rapid growth of Internet service types, and the continuous improvement of service quality, the demand for user bandwidth is increasing rapidly, and the broadband access network of telecom operators is facing increasing load pressure. The bandwidth expansion speed of operators has gradually failed to keep up with the growth rate of broadband users. At the same time, the diversity of users' usage habits, work schedules, etc. has become more and more obvious. The traditional method of expanding the number of new users is huge, and it is impossible to Meet the needs of network development. The development of broadband networks relies on a wider range of resource sharing to achieve efficient use of resources rather than blind physical bandwidth resources. In the traditional broadband network, the network bandwidth is planned to realize the sharing of bandwidth resources at the cell level and the small office according to the number of users, including the line bandwidth resources and the service node bandwidth resources. From the current network development speed, the line bandwidth resources are relatively The bandwidth of the service node is relatively sufficient, and the latter has obviously encountered a large resource dilemma. A very representative problem is that most users cannot enjoy the maximum bandwidth promised by the operator during the peak hours. During this time, most of the users are concentrated in the residential area of the city. The bandwidth of the service nodes in the residential area is extremely high, and the service nodes in the urban office area are generally in a low usage rate or even idle state. On the contrary, the resource utilization rate of broadband network equipment in urban residential areas during working hours is much lower than that in the evening peak hours. How to solve the problem of resource utilization efficiency of broadband networks, and thus maximize the utilization of existing network resources, reduce the frequency of expansion, and reduce the investment in network costs, which is one of the major problems faced by global telecom operators. In the field of broadband access, the resource utilization of service nodes (ie, broadband access servers, service routers, etc.) is the main requirement. The current mainstream technical solution in the industry is a pooling solution for service nodes. Through a wider range of service node resource sharing, rational utilization of broadband resources in all-weather and large-scale areas is realized, and peak-time valleys in different regions are realized under limited resources. The resources are complementary and the resources of different types of users are shared. In terms of the resource pool grouping technical solution of the service node, the user information and the network information sharing between different service nodes are first realized. The current mainstream solution is distributed negotiation between service nodes, so-called Full Mesh (fully interconnected) The way to achieve full sharing of information between business nodes. At the same time, as the types of user services become more and more diverse, different types and levels of services have different requirements for service quality and high reliability. It is becoming more and more important to provide different levels of quality assurance requirements for different services. Business needs to meet the needs of providing users with differences The need for service, while also saving network resources. However, with the increasing scale of resource sharing, this method will inevitably lead to a huge number of connections and difficult to manage.

After receiving the online user information, the preferred backup service node stores the user information on the device control plane and/or sends it to the device forwarding plane. Step S806: When the status of the user service node is abnormal, the pool grouping control device designates the preferred backup service node as the new active service node, and selects one of the other backup service nodes to become the new preferred backup service node. When the status of the primary service node is abnormal, the pooled control device notifies the preferred backup service node and the access network device, and sends the data packet of the user group affected by the abnormal state to the preferred backup service node.
