학회: 2021 IEEE 9th International Conference on Information, Communication and Networks (ICICN)

the basic concepts of OSPF routing protocol and SDN mechanism are illuminated, single area OSPF protocol will generate a large scale of LSDB data about network devices and affect the normal operation of the network. On the contrary, the multi area OSPF protocol will reduce the size of LSDB and alleviate the load of the network. What’s more, the network deployed by SDN can overcome the complex disadvantages of multi area OSPF network. The network model based on SDN and multi area OSPF is proposed. After carrying out simulation experiment successfully, a campus network of a single OSPF area is reconstructed based on SDN and multi area OSPF, the performance of the new network has achieved satisfactory results.
