Simulation and Research of OSPFv3 Performance

OSPFv3 is an interior gateway routing protocol, which is widely used in IPV6 environment. It is the realization of OSPFv2 for IPV4 in the IPV6 environment. They are the same in the basic principles. The paper uses the OPNET network simulation software to simulate and analyze the performance of OSPFv3, and found that both the convergence period is the same roughly, the flow is concentrated in the first few seconds. But they also have many different aspects, a change in the packet format, and the type of LSA. There is no address information in OSPFv3 and the main LSAs. Router LSA is only 83% of OSPFv2. Router ID does not have any practical significance. Although IPV6 address is 4 times the IPV4 address, both are the same roughly in the memory and running time. And there are many improvements.
