Abstract
A method, a network access point and a communication system are disclosed for admitting data flows corresponding to new service requests to a multiple access network. The method includes the steps of receiving a service request having Quality of Service (QoS) requirements from a network node (410), calculating the effective bandwidth required by a data flow corresponding to the service request based on an average packet size of the data flow (420), determining the maximum capacity of the network (430), and admitting the data flow corresponding to the service request (445) if the network has sufficient capacity to accommodate the effective bandwidth required by the data flow. The average packet size of a data flow corresponding to the service request can be determined from the service request for calculating the effective bandwidth required by the data flow. The maximum capacity of the network can be determined based on the number of transmitting nodes in the network. If the transmission rate of the service request is less than the maximum transmission rate of the network, the effective bandwidth required by the new data flow can be adjusted.
