Method and equipment for processing congestion notification message

The invention provides a method and equipment for processing a CNM (Congestion Notification Message). The method comprises the following steps: acquiring the source routing information from the CNM, which results in the CNM from the CNM; reversely searching a routing list item in a routing list, which corresponds to the source routing information; and sending the CNM to an MAC (Media Access control) address in the routing list item corresponding to the source routing information. The source routing information is acquired from the CNM, and the MAC address of original data sending equipment is found out according to the source routing information, so that the problem that the CNM generated after a message is forwarded can not be forwarded to the original data sending equipment is solved, the CN (Congestion Notification) function can still take effects, and the CNM is utilized to notify the original data sending equipment to regulate the data sending rate in case of congestion in an FCOE (Fiber Channel Over Ethernet) network or a three-layer IP (Internet Protocol) network, so as to eliminate network congestion.
