Research On The Deployment Mechanism Of Functional Chain Of Service Offloading In Smart Integration Identifier Networking

At present,the traditional architecture of the network has some design flaws.With the rapid and high-quality development of the Internet,the traditional network architecture is no longer able to support the scale of the Internet,exposing many problems.In order to solve the problems exposed by traditional networks,Intelligent Identity Network has introduced a new concept of network structure design: hierarchical and domain wise integration,in order to solve the problems existing in traditional network architecture.Zhirong Identification Network is committed to the implementation of heterogeneous network collaboration,by fully utilizing rich network resources,and ultimately achieving intelligent integration of heterogeneous resources,as well as collaborative scheduling that adapts to different types of service requirements.With the development of virtualization of various network services and the invention and development of hardware for implementing virtual network functions,the use of different types of service resources and improving resource utilization have become a research hotspot for network researchers.Therefore,this article focuses on the offloading scheme of programmable switches’ network functions in the smart identity network,The aim is to solve the problem of traditional service function chains not fully utilizing switch service resources,and improve the overall utilization rate of network resources.This article designs and implements a function chain deployment mechanism based on service offloading in the intelligent integration identification network.This service combines in band network telemetry,network function deployment,and programmable data plane to achieve network function deployment.Based on this,network function offloading is implemented based on network state.The main work of this article is as follows:Firstly,this article designs a service implementation based on a programmable data plane,and implements modules such as service management module,data storage module,and adaptive deployment module.By addressing the issue of incomplete collection of switch specific information by existing network state information collection tools,which makes it difficult to model it uniformly with container resource conditions,it is proposed to use in band network telemetry to better perceive network state information,which can then be modeled uniformly from a latency perspective,and the information can be collected and transmitted to the corresponding server’s data storage module.Secondly,this article explores the issue of existing network function deployment algorithms not taking into account switch service resources,and develops corresponding network function offloading schemes.Then,this article designed the algorithm for unloading,provided a specific design idea on the data plane,as well as the data items for in band network telemetry collection and the specific implementation of the adaptation algorithm.Finally,this article established an experimental topology and conducted functional and performance tests on the designed in band network telemetry information collection and network function offloading scheme.The test results showed that the network function offloading scheme proposed in this article can more effectively utilize network bandwidth and service resources.
