Amendment 13: Congestion Notification

Approved 25 March 2010

Abstract: This amendment specifies protocols, procedures and managed objects that support congestion management of long-lived data flows within network domains of limited bandwidth-delay product. This is achieved by enabling bridges to signal congestion to end stations capable of transmission rate limiting to avoid frame loss.
Keywords: congestion, congestion notification, LANs, local area networks, MAC Bridges, transparent bridging, VLANs
