Communication node, a receiving node and methods therein

摘要

A method in a communication node for handling a packet to a destination node in a communications network, and associated nodes. The communication node associates the packet with a remaining value, with the remaining value being a packet value reduced by a threshold value of an outgoing link from the communication node towards the destination node. The threshold value corresponds to a congestion level of the outgoing link. The communication node further handles the packet based on the remaining value, the handling including determining whether to drop or to transmit the packet along the outgoing link based on the remaining value.

1. A method, in a communication node, for handling a packet to a destination node in a communications network, the method comprising:
associating the packet with a remaining value, the remaining value being a packet value reduced by a threshold value of an outgoing link from the communication node towards the destination node, the threshold value corresponding to a congestion level of the outgoing link; and handling the packet based on the remaining value, the handling comprising determining whether to drop or to transmit the packet along the outgoing link based on the remaining value; receiving a first packet of feedback, over the outgoing link and from another communication node, indicating a second threshold value; and adding the threshold value to the first packet of feedback and forwarding the first packet of feedback over an incoming link.
