Transformation of Campus Network Based on GLBP and PBR

This paper reconstructs a campus network based on GLBP and PBR to meet the needs of campus network users. Two new Internet operator export links are added, which not only increase the campus network exit bandwidth, but also diversify the campus network exit link. Two high performance Cisco 7206 routers are deployed in the campus network core layer and the gateway load balancing protocol works between them. The test results show that the network transformation not only realizes the redundancy of the three-tier gateway and the balance of the traffic load, but also enables the campus network users to access the packets of Internet resources, which can be forwarded according to the optimal path strategy formulated by the network manager in advance.
