End-to-End Congestion Control for System Area Networks

Overview System Area Networks (SANs) using link-level flow control experience congestion spreading, where one bottleneck link causes traffic to block throughout the network. In this paper, an end-to-end congestion control scheme is proposed that avoids congestion spreading, delivers high throughput, and prevents flow starvation. It couples a simple switch-based ECN packet marking mechanism appropriate for typical SAN switches with small input buffers, together with hybrid window and rate control at end-devices.
