METHOD AND SYSTEM FOR MANAGING ADMISSION TO A NETWORK

A method and system for managing admission to a network considers the packet delay of the network in making an admission decision. The packet delay of the network is periodically probed. To avoid disturbing or impairing the traffic of the network, a sequence of probing packets is sent to the network at an irregular interval. Responses to the probing packets are analyzed to obtain delay information of the network. If the delay information is insufficient to make an admission decision, then the packet loss rate of the network is measured and considered.
