Abstract

This paper investigates the performance implications of several end-to-end flow-control schemes based on the ServerNetR systemarea network. The static window (SW), packet pair (PP), and the simplified packet pair (SPP) flow control schemes are studied. Additionally, the alternating static window (ASW) flow control is defined and evaluated. Previously, it has been proven that the packet-pair scheme is stable for store-and-forward networks based on Rate Allocation Servers. The applicability of a PP flow control to wormhole-routing networks is studied and evaluated through simulation. It is shown that if high throughput is desired, ASW is the best method for controlling the average latency. On the other hand, if low throughput is acceptable, SPP can be applied to maintain low latencies.
