Abstract

The invention discloses a switch system based on a service function chain. For the problems that a switch node data plane is fixed, the function expansibility is bad and the resource is over-configured, a flexible network processing function is provided for a data packet in a network function pool way by separating a non-general function from a line card. The data packet is divided into differenttypes by a classifier through a matching rule, for the data packet needing the non-general network function processing, the network function instance (non-general network function) needing to be processed is found in a network function instance list of a flow table according to a data packet matching domain, and the processing is performed by a service function chain composed of corresponding different network functions in the network function pool. Compared with the traditional switch system, P4 architecture and like existing research techniques, the switch system disclosed by the invention has the following advantages: the high-level network function is supported, the data traffic processing rule can be flexibly extended, the change is dynamic, the resource utilization efficiency is improved, and the capital expenditure and the operation cost are reduced.

Description

technical field [0001] The invention belongs to the technical field of network switching equipment, and more specifically relates to a switching system based on a service function chain. Background technique [0002] 1. Development history of switches [0003] With the continuous expansion of the Internet scale and the diversification of network application services, the design concepts and architecture of switches in traditional networks have increasingly exposed their shortcomings. First of all, traditional switches are designed as closed "black boxes" by major manufacturers, and their openness, scalability and interoperability are poor, resulting in slow network updates and complicated equipment management; The processing mode of Pipeline) has problems such as poor scalability of line card functions and waste of resources caused by "over-configuration" of processing capabilities; finally, the diversified requirements of network services require that switches should not o...
