Based on the analysis of basic operation process of the IS-IS(Intermediate System to Intermediate System)protocol, the paper provides a LSP (Link State Packet) diffusion model of the IS-IS protocol with the GSPN(generalized stochastic petri nets).And the simulation results show that the router's load becomes heavier significantly if the network structure's variation is greater.And also from the simulation, it is indicated that the inter-area router's load is the major load of all the routers.So the LSP(Link State Packets)diffusion timeconsuming can be reduced by improving the performance of the inter-area router in order to guarantee the fast convergence of the protocol routing computation.
