Problems solved by technology

The more processing units and service boards used for backup, the greater the redundancy and reliability; however, the more complex the business load switching or switching strategy when a failure occurs at the same time, the higher the implementation cost, which may reduce the system reliability

Embodiment Construction

[0023] Next, specific implementations of the packet switching device and the method for managing user services in the present invention will be described in detail with reference to the accompanying drawings.

[0024] attached figure 1 Shown is a schematic structural diagram of the packet switching device in this specific embodiment, including: multiple identical service resource groups, represented by service resource groups 11 , 12 and 13 in this embodiment, a router 14 and a control module 15 . Each service resource group includes multiple service modules. In this embodiment, service resource group 11 includes service modules 111 , 112 and 113 , and service resource group 12 and service resource group 13 also include multiple service modules. The business resource groups 11, 12 and 13 are completely identical to each other, and the business modules in the business resource groups are also identical to each other. Service modules and service resource groups can be deployed ...

Abstract

The invention relates to packet switching equipment and a method for managing customer service. The packet switching equipment comprises a plurality of same service resource groups, a router and a control module, wherein each service resource group comprises a plurality of service modules the same to one another, the service resource groups are all connected with the router and switch customer service messages to the router, the control module is connected with a plurality of service resources and is responsible for managing the user context information on the service resource groups so that the user contexts among the service modules in every service resource group are synchronized. Through the invention, the user service flow on the service module is quickly switched to another service module of the same group or switch back to the recovered module by distributing the service resource group to the service module when one service module is out of order or recovered from the failure.

Description

technical field [0001] The invention relates to the field of communication and computer technology, in particular to a packet switching device and a method for managing user services. Background technique [0002] In the field of communication, with the development of multimedia services, the bandwidth used by user services is gradually increasing, and the application of real-time multimedia services is becoming more and more extensive. This puts forward higher and higher requirements for the processing capability and reliability of packet switching equipment. These devices are required not only to have high business throughput, but also to have extremely high reliability and fast fault recovery capabilities. [0003] Reliability is generally reflected in the business processing unit or board with 1+1 backup capability, or N+1 load sharing capability. When a processing unit fails, the original business load on this unit can be quickly taken over by other processing units, m...
