A Framework of Flow Control in High-speed Atm Wide Area Networks

In this paper, we propose a two-layer framework of jlow control in high-speed A TM wide area networks. At the upper layer of network level, we classify trafic into two categories, delaysensitive and delay-insensitive. With the advancement of perVC queueing in ATM switch design, we propose peak-rate allocation and therefore no jlow control for delay-sensitive traffic, and hop-by-hop credit-based j70w control for delay-insensitive trafic. At the lower layer of node level, we introduce a cell scheduling algorithm which has the capability of multiplexing two types of trafic and satisfying diverse delay and loss requirements from the upper layer,
