Performance management method and device for service function chain system

Abstract

The invention discloses a performance management method and device for a service function chain system and relates to the field of communication. The method comprises the steps that a monitoring module of a service function chain controller receives performance index data of the service function chain system; the monitoring module receives node performance data sent by monitoring agent modules of service nodes; and the service function chain controller selects the service nodes to establish a service function chain based on the performance index data and the node performance data and monitors and manages function nodes in the service function chain. According to the performance management method and device for the service function chain system provided by the invention, a service function chain performance management monitoring mechanism is increased; the service function chain controller can monitor the performance of the service nodes in real time; the service function chain system can satisfy special performance demands of user or third party service; the service function chain with performance guarantee is established for a customer; the service nodes in the operated service function chain can be timely replaced; the reliability of the service function chain system is increased; and the utilization efficiency of the service function nodes is improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a performance management method and device for a service chain system. Background technique [0002] With the continuous application of virtualization concepts and technologies such as SDN (Software Defined Network, Software Defined Network) and NFV (Network Function Virtualization, Network Function Virtualization), traditional networks are also evolving and developing in the direction of virtualization. Service Function Chain (Service Function Chain) technology defines the corresponding service chain processing mode in the business service node by adding the service chain header, so that the flexible processing of the service node can be easily realized, and the flexible and changeable service chain configuration requirements can be simplified. Improve the processing efficiency of business nodes. At present, the typical networking structure and component types of SFC (Se...

exist figure 1 In the typical structure of the service chain, the SFC controller only issues rule attributes such as the forwarding policy table and flow classification table to each network element node in the service chain system, but lacks information on the relevant nodes of the service chain, especially the service processing and Monitoring of performance indicators of SF service nodes

This lack makes the service chain system unable to meet the performance-specific requirements of users of different levels for the same kind of SF service nodes in the service chain network. Moreover, when the working SF service node has an alarm of insufficient performance, it cannot be switched quickly, so that the service The reliability of the chain system has dropped significantly
