The “One Network” project first upgrades and transforms the campus core network, increasing the backbone bandwidth of the core network from 80 to 200G, deploying SDN controllers, and enabling multi-purpose use of the network for intelligent business deployment. The project interconnects the cores of various campuses through F5G’s optical transmission technology OTN equipment to construct an OTN ring network. The school deploys 100G OTN optical transmission equipment in the core computer room, forming a 50 ms rapid switchover protection ring network.
