Congestion control in HPR
J. Martin, A. Nilsson · 2002
High performance routing (HPR) is an enhancement to IBM's advanced peer to peer networking (APPN/sup TM/) protocol that improves its performance and reliability. In an HPR network, the rapid transport protocol (RTP) is used for end-to-end data transfer. RTP provides a reliable, in-order delivery service using a selective repeat protocol as the end-to-end error recovery mechanism. Additionally, RTP provides an end-to-end, adaptive rate-based (ARB) flow/congestion control mechanism that is designed to avoid congestion and maximize network stability. This paper describes the ARB algorithm. Simulation results are presented illustrating the behavior and the stability of the algorithm.
