Abstract

A method of operating a packet dropper 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, wherein congestion is indicated to the sending hosts by way 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, thereby producing either conformant flows or non-conformant flows, depending on whether the amount of congestion response packets is balanced with the indicated congestion level or not, is characterized in that the packet dropper carries out in succession a series of traffic analyzing steps for identifying the non-conformant flows. Furthermore, a corresponding packet dropper for use in a congestion exposure-enabled network is described.
