Abstract:
1. A method for supporting congestion management in a congestion exposure-enabled network, comprising: sending flows of packets over network paths between sending hosts and receiving hosts via one or more intermediate routers; and upon detecting congestion, marking packets of said flows as congestion packets by including congestion information, wherein congestion is indicated to the sending hosts by means of 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, wherein aggregated congestion is determined on the basis of congestion information included in packets that are sent over said network paths between said sending hosts and said receiving hosts, wherein a path congestion prediction regarding the expected congestion level on a path is derived from said aggregated congestion, wherein network-generated hints are provided, said hints including said path congestion prediction, wherein said network-generated hints are disseminated to network elements and/or end hosts, and wherein said network-generated hints are employed for assisting said end hosts in events of mobility.
