(Ruijie Networks joined hands with xx University to upgrade the 10G campus network: the backbone network was upgraded to a 10G network. Any important area of ??the school to the service area group and egress routers are all 10 Gigabit links; multi-core, conical backbone network design. There is only one-hop route from any important area of ??the school to the server group and the egress; four-tier architecture, dual-homing design for regional aggregation. The architecture fully guarantees the stability and reliability of the network; unified identity authentication for the entire network. User management based on SAM system, and a large number of secondary development in line with school characteristics. In the reconstruction of the backbone network, three core switches RG-S8610 were added in Huashan, East District, and the five groups to form a 10G ring network and undertake the core network of South China Agricultural University. At the same time, the three core switches and the egress router Cisco C7606 formed a conical In the network framework, the 10G backbone data flow is accumulated on the egress router. The upgrade of the 10 Gigabit backbone has caused a sharp increase in intra-campus traffic, and the intra-campus bandwidth bottleneck has been well resolved, and it has also brought new adjustments to the egress network. There are nearly 40,000 information points on the campus network of South China Agricultural University. Such dense information points have had a strong impact on the export of South China Agricultural University. The egress bandwidth utilization rate is close to 100%, and the egress bandwidth is extremely tight (the egress line status of South China Agricultural University in 2007 is: 1000M for education network, 100M for telecommunications), teachers and students generally report that Internet access is often slow, affecting office, teaching, and life. development of online usage.)
