A heterogeneous service function chain forwarding protocol and method in an intelligent identification network

Abstract

The present invention provides a heterogeneous service function chain forwarding protocol and method in an intelligent financial identification network. The method includes: parsing a user input data packet, matching the data packet with a group identifier FID according to user requirements, encapsulating the Sinet_nsh packet header field, and outputting the data packet to the network component layer; the edge gateway in the network component layer is based on the user source IP of the Sinet_nsh data packet. , Destination IP and FID triple input data fill in the content of the Sinet_nsh header, and transmit the packet encapsulated with the Sinet_nsh header to the forwarding switching node; the forwarding switching node matches the next-hop network function attribute in the Sinet_nsh header and the status of the transfer context service function chain After receiving the data packet, the last hop network function forwarding switch node converts the data packet into an ipv4 data packet and outputs it. The present invention designs a modular heterogeneous service function chain based on micro-services, thereby optimizing the heterogeneous SFC framework and realizing multi-dimensional integration of heterogeneous network resources.

Description

technical field [0001] The present invention relates to the technical field of network heterogeneous service deployment, in particular to a heterogeneous service function chain forwarding protocol and method in an intelligent identification network. Background technique [0002] The ever-increasing business traffic and diversified business types have put forward higher requirements on the service model and service capability of the network. The network not only needs to provide flexible and customizable service content for different services, but also needs to ensure service quality and transmission efficiency according to service requirements. Based on "three layers" and "three domains", Zhirong Identification Network proposes a new type of intelligent routing and switching system, in which the resource adaptation layer deploys the service functions to the network component layer, enabling them to realize the corresponding service functions and link them in sequence to form...

Problems solved by technology

[0005] The disadvantages of the first heterogeneous service function chain deployment method in the above prior art are: although this method can support business diversification and flexibility, efficiently support third-party business innovation, provide high security, and support automatic deployment and operation dimension, but the virtualization method it adopts is relatively limited, and there are few considerations for the application scenarios of the service function chain

Although virtual machines and docker containers have relatively flexible deployment capabilities, the service function chain built by them has a large bottleneck in performance, and it is difficult to support services with high QoS requirements

[0006] The second deployment method of the heterogeneous service function chain in the prior art includes: With the continuous expansion of the user scale and the continuous extension of the application field, the existing Internet presents a "static" and "rigid" situation due to the lack of original design, It is difficult to support the on-demand supply and flexible networking of personalized services. This method proposes a smart identification network architecture. Through the intelligent integration of multi-space and multi-dimensional resources in the entire network, the service level is vertically associated with the network level. The horizontal decoupling of service space and network space realizes the separation of control management and function execution, aiming to provide on-demand supply of personalized services and flexible networking

[0007] The disadvantage of the second method of deploying heterogeneous service function chains in the prior art is that although this method can provide efficient and flexible differentiated , Customized communication network services, but still in the research stage, and did not make full use of the characteristics of various network components in the network component layer, the support method for the service function chain is still relatively simple, and it is difficult to support services that require high service quality
