Method and an arrangement in a first network node for managing congestion

摘要

A method and an arrangement (400) for managing congestion of outgoing data of at least one link in a telecommunications signalling network protocol stack, comprising a first and second layer and an interface there-between, are provided. The first network node comprises multiple processing modules (430). The first network node (110) determines (210) a congestion level between the first and second layers. The first network node (110) receives (220), from the first layer, any existing first layer congestion level indication, indicating congestion between the first layer of the first network node and the first layer of the second network node. The first network node (110) generates (230) a simulated first layer congestion level indication based on the determined congestion level. The first network node (110) generates (240) a total first layer congestion level indication based on the simulated first layer congestion level indication and said any existing first layer congestion level indication.

1. A method in a first network node for managing congestion of outgoing data of a link, wherein said link interconnects the first network node and a second network node, the first network node comprises a first protocol stack comprising a first layer, a second layer, and an interface between the first layer and the second layer, the second network node comprises a second protocol stack comprising a first layer, a second layer, and an interface between the first layer and the second layer, the method comprising:
determining a congestion level between the first and second layers of the first network node, receiving, from the first layer of the first network node, an existing first layer congestion level indication indicating congestion between the first layer of the first network node and the first layer of the second network node, generating a simulated first layer congestion level indication based on the determined congestion level between the first and the second layers of the first network node, and generating a total first layer congestion level indication based on the simulated first layer congestion level indication and said existing first layer congestion level indication.
