RESOURCE ALLOCATION DEVICE AND METHOD TO MULTIPLE ACCESS NETWORKS ACCORDING TO A NETWORK CONDITION OF EACH

摘要

Resource allocation device for allocating resources of a transport medium shared by multiple access networks, comprising: an estimating unit to estimate for each access network an internal network condition, said internal network condition being representative for internal resources which are available within the respective access network, such as a traffic latency; a traffic weight calculating unit to calculate for each access network a traffic weight based on the respective estimated internal network condition, a higher traffic weight being representative for more internal resources being available and a lower traffic weight being representative for less internal resources being available; a resource allocation unit to allocate resources of the transport medium to each access network, based on the calculated traffic weight of the respective access network, more resources being allocated to an access network with a higher traffic weight and less resources being allocated to an access network with a lower traffic weight. The resource allocation may be carried out by means of weighted fair queuing algorithm, and considerations of the traffic class or QoS of the traffic are a secondary criterion after taking into account the network condition of the access network from where the traffic is received.
