摘要： Various exemplary embodiments relate to a method and related network node including one or more of the following: receiving, at the network node, a packet belonging to a flow, the packet including a marking used to identify a quality of service (QoS) required for the packet; assigning a compression context identifier to the packet; queuing the packet in a queue selected from a plurality of queues based on the marking in the packet; identifying a period of congestion and, in response, blocking the packet; when the period of congestion has ended and the packet is dequeued, determining whether the QoS associated with the packet is the same as a QoS stored in a context identifier storage; and when the QoS associated with the packet is not the same as the QoS stored in the context identifier storage, determining that the flow has expired and discarding the packet.
