[Abstract]:The Internet has penetrated into all aspects of social life, and the number of users and the scale of the network have increased explosively, which has exposed the problems of poor security and difficult deployment of the new routing system. More and more scholars at home and abroad pay attention to the research of network architecture and key technologies in the future. The National Engineering Laboratory of next Generation Internet Interconnection equipment of Beijing Jiaotong University, the National 973 Project "basic Research on the Theory of Intelligent Cooperative Network", puts forward the intelligent cooperative network architecture of dynamic adaptation of resources. According to its design concept, a prototype system of intelligent cooperative network, CoLoR, is built to verify the feasibility of intelligent cooperative network. CoLoR allows different autonomous domains to run different routing systems in the network and supports heterogeneous networks. In this paper, we combine the routing mechanism of Segment routing with CoLoR, and make SR network support CoLoR, forming SR-CoLoR domain, which is an important part of CoLoR prototype system. Therefore, the work of this paper not only makes an important contribution to the construction of CoLoR prototype system, but also has important significance to verify the correctness and usability of intelligent collaborative network system. The main work of this paper is as follows: firstly, the background, significance and related theoretical basis of this paper are briefly introduced, including CoLoR SR and so on. Secondly, by analyzing the key components of SR and CoLoR, the SR-CoLoR system is designed and divided into control plane subsystem and data plane subsystem. The control plane subsystem is mainly responsible for routing computing, service resolution and service registration, while the data plane subsystem is responsible for the adaptation of the SR mechanism and the extraterritorial CoLoR mechanism in the domain and the forwarding of the data. At the same time, the module of the system is designed. Thirdly, the SR-CoLoR system is implemented based on ClickRouter software routing platform. The control plane subsystem includes a PCE controller and a resource manager, wherein, the PCE controller includes a SR-TE path calculation module, a SL optimization module, a Sid tag management module, a aware message module, and a resource manager RM including service registration. Service parsing CoLoR packet processing module SR packet processing module four main modules. The data plane subsystem includes a boundary router, an access router and an in-domain SR router. The boundary router comprises a packet classification module, a CoLoR data packet processing module, a sensing message processing module, and a PCEP session processing module. The access router includes packet classification module get / REG packet processing module and data packet processing module. Finally, the CoLoR prototype system is deployed to verify the function and test the performance of the SR-CoLoR system. Function verification includes path calculation module of control plane subsystem, service resolution module and verification of each router of data plane subsystem. The performance test includes the implementation of the CPU occupancy rate of the control plane subsystem and the implementation of the traffic engineering mechanism. The compatibility of the intelligent collaborative network prototype system with SR is verified, and the traffic engineering mechanism in the CoLoR network is realized by SR. CoLoR in favor of the deployment in the large network.
