Abstract
A system and method is provided for sending congestion notification messages through L3 networks and implementation of QCN in L3 switches. For example, according to this system and method, an L3 switch receives one or more data packets, and determines, based on the received one or more data packets, whether the L3 switch is congested. If the L3 switch is congested, it generates a congestion notification message, the congestion notification message including an Internet Protocol (IP) header, the IP header identifying a source of the one or more received data packets as its destination. The L3 switch sends the congestion notification message to the source of the one or more received data packets using information in the IP header.
