Abstract

Compared to the overdimensioned designs of the past, current interconnection networks operate closer to the point of saturation and run a higher risk of congestion. Among proposed strategies for congestion management, only the Regional Explicit Congestion Notification (RECN) mechanism achieves both the required efficiency and the scalability that emerging systems demand.
