- Abstract
- PNNI (private network network interface) routing establishes the connection between end-to-end users based on topology database by source routing and can efficiently use network resources by dynamic routing. Also, PNNI can be used at large networks by organizing hierarchical networks based on peer group. The methods for topology aggregation such as star, full-mesh, and spanning-tree have been studied. Presently, the method for considering various parameters has been studied. This paper compares and analyzes the above methods of topology aggregation in PNNI. For performance test of the above methods, we developed the simulator based on PNNI 1.0 specification. Our simulator is based on ATM PNNI Routing Protocol Simulator (APRoPS) of National Institute of Standards and Technology. APRoPS is developed for the test of ATM routing efficiency and the analysis of ATM routing protocols according to PNNI 1.0. Using APRoPS, NIST has studied the stability test and scalability of PNNI routing protocol. In this paper, using our simulator, we simulate the above methods that can aggregate topology considering various parameters. An efficient topology aggregation algorithm has a great influence on network efficiency and scalability in PNNI network.
