IMPROVED RESOURCE ALLOCATION PLAN IN A NETWORK

摘要

A method and Resource Allocation Manager Entity for obtaining an improved resource allocation plan for the network. Traffic requests currently exist in a network, each of which having a source, a destination and at least one Quality of Service (QoS) requirement being represented by a QoS value. For each traffic request, at least one potential path consisting of a plurality of links is computed. An iteration matrix is generated having the potential path on first axis, the links on second axis and the QoS requirement on third axis. The iteration matrix is filled by, for each of potential path, distributing the QoS value of the QoS requirement over the links for enabling a gradient space calculation method on the iteration matrix. The gradient space calculation method is applied to the iteration matrix until an iteration marker thereof indicates that the iteration matrix contains the improved resource allocation plan.
