Next hop resolution using classical IP over ATM

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 ATM network, also requires that the router be used between different LISs (Logical IP subnet). However, the intervention of the router is not always an effective solution on ATM network. If there is a direct virtual channel connection between two endpoints on ATM network, they can exchange their information directly without the help of routers. Actually, some groups of IETF and ATM Forum are looking on such tasks. As the results, NHRP (Next Hop Resolution Protocol) or MPOA (Multi-Protocol Over ATM) are being drafted. However, since those protocols are too heavy and complicate, it is not easy to implement. In this paper, we propose a simple efficient solution for inter-LIS communication. 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.
