Abstract:
Aimed at the high demand for interdomain campus network in management, maintenance and scalability, the interdomain campus network has been constructed using the technique of BGP/MPLS (Border Gateway Protocol/Multi-Protocol Label Switching) VPN (Virtual Private Network). With the OPNET simulation software, the interdomain campus network which contains the three school ranges across the region, divides VPN service in accordance with business system and network configuration realizes the communication in the school range through the same VPN service. The network property is analyzed. The expanding interdomain campus network which adds a VPN service in each school range has been constructed. By comparing to the simulated result of the network property of two scenarios, we conclude: CPU utilization of the P and PE (Provider Edge) devices before and after the services expansion, is relatively stable, no greater impact; The expanded network latency and load compared to the original network did not show a monotonically increasing trend, network delay actually decrease the load increases, but the change is relatively stable. In summary, the interdomain campus network in the BGP/MPLS VPN technology has good scalability.
Key words: simulation analysis, network scalability, inter-domain campus network
