Abstract
A method for supporting congestion management in a congestion exposure-enabled network, wherein sending hosts and receiving hosts communicate with each other by sending flows of packets over network paths via intermediate routers, which, upon detecting congestion, mark packets of the flows as congestion packets by including congestion information, wherein congestion is indicated to the sending hosts via a congestion feedback mechanism, and wherein the sending hosts, upon receiving congestion indications, declare a subset of the packets they send as congestion response packets by including congestion information, depending on whether the amount of congestion response packets is balanced with the indicated congestion level or not is characterized in that aggregated congestion is determined on the basis of congestion information included in packets that are sent over the network paths between the sending hosts and the receiving hosts. Furthermore, a corresponding congestion exposure-enabled network system and a corresponding intermediate router are disclosed.
