Abstract
A method and apparatus are provided for communicating congestions that area detected in a communications network. According to the method and apparatus, a first Ethernet frame encapsulating a first PDU is transmitted across an Ethernet network. Congestion in the network is then detected, and an indication of the congestion is inserted in a predetermined header field of the first Ethernet frame. Once the first Ethernet frame is received by an endpoint in the network, the indication of congestion is transferred into a second PDU that is associated with the first PDU. The second PDU is then encapsulated in a second Ethernet frame and transmitted towards the sender of the first PDU.
