To extend the widespread use of HIPPI as a networking solutions for high-speed communications, the 25-meter distance limitation must be solved. Three options available for alleviating the problem of distance limitation of HIPPI networks are SerialHIPPI, HIPPI/SONET mapping or HIPPI-ATM mapping, and IP Routing. SerialHIPPI, HIPPI/SONET mapping and HIPPI-ATM mapping provide extended HIPPI connectivities at the physical layer, while IP Routing forwards data between HIPPI networks and other networks at the network layer. In this paper, we study two feasible solutions of this problem, HIPPI Tunneling (HIPPI-ATM mapping) and IP Routing. We compare these two schemes in terms of network connectivities, protocol overhead, and flow control. The performance evaluation of one implementation of the HIPPI tunneling and IP Routing is presented. Experimental performance suggests that a high degree of bandwidth utilization was achieved by both HIPPI Tunneling and IP Routing in this implementation.
