At an Edge Node, a method of handling data packets in order to mark the packets with respective packet values indicative of a level of importance. The method comprises implementing a variable rate token bucket to determine an estimated arrival rate of a flow of packets. The method comprises receiving a data packet, updating the estimated arrival rate to an updated arrival rate based on a token level of the token bucket and generating a random or pseudo-random number within a range with a limit determined by the updated arrival rate. The method further comprises identifying an operator policy which determines a level of service associated with the flow of packets, and a Throughput Value Function (TVF) associated with said policy, and then applying the TVF to the random number to calculate a packet value. The packet value is included in a header of the packet.

Probabilistic packet marking with fast adaptation mechanisms

A method, in a first node, for handling one or more jobs, wherein said first node receives a job over an incoming link, which job comprises a job value, wherein said method comprises the steps of determining, by said first node, a deviation of a queuing delay of the first communication node from a target queuing delay value, and using, by said first node, said deviation as an error value to determine a dropping probability which is used to determine a threshold value, wherein said threshold value corresponds to or is associated with a congestion level of a queue of the job, comparing, by said first node, the job value with the threshold value and establishing that said job value is below said threshold value, dropping, by said first node, said job based on said comparison.
