Methods and apparatus for shared buffer allocation in a transport node

Abstract:

A method (200) for controlling shared buffer capacity in a packet switched network is disclosed, the packet switched network comprising a plurality of transport nodes, each node comprising a shared buffer capacity which may be allocated to interfaces of the transport node. The method comprises obtaining a configuration of traffic flows within the network (210). The method further comprises, for a transport node, determining, on the basis of traffic flows within the network, an allocation of the transport node's shared buffer capacity between interfaces of the transport node to limit overall packet latency for the transport node (220), and causing the determined allocation of shared buffer capacity to be applied in the transport node (230). Also disclosed are an apparatus (600, 800) and a transport node (700, 900) in a packet switched network and a computer program product configured to carry out methods in a packet switched network and a transport node.
