Abstract
Abstract A method, apparatus and system of network congestion notification is disclosed. A source node sends a destination node a data packet. Upon receipt of the data packet if network congestion is detected, the destination node introduces a congestion indication into a data packet. The data packet, including the congestion indication, is sent to the source node.
