IP routing on logical address group

Abstract

In principle, more than one routers are intervened between different IP subnets. IETF RFC1577 "Classical IP and ARP over ATM", which is specified to provide IP services on an ATM network, also requires that the router be used between different logical IP subnet (LISs). However, the intervention of the router is not always an effective solution on an ATM network. If there is a direct virtual channel connection between two endpoints on the ATM network, they can exchange their information directly without the help of routers. Actually, some groups of the IETF and ATM Forum are working on such tasks. As a result, the Next Hop Resolution Protocol (NHRP) or MultiProtocol Over ATM (MPOA) is being drafted. However, since those protocols are too heavy and complicated, they are not easy to implement. We propose a simple efficient solution for inter-LIS communication-LIS Information Protocol. Our solution is exactly compatible with RFC1577. We describe how RFC1577 can be used to provide inter-LIS communications and introduce our prototype systems and test-bed network.
