Abstract
Connection admission control to an ATM network from a plurality of sources sharing a common virtual channel connection in which information packets are carried in cells is effected by determining whether that connection requires the transmission of a single packet per cell, partially filled cells containing more than one packet or fully filled cells. Where a single packet is to be transmitted per cell, the bandwidth requirement is calculated via a first algorithm. Where fully filled cells are to be transmitted, the bandwidth requirement is calculated via a second algorithm. Where partially filled cells containing more than one packet are to be transmitted the bandwidth requirement is calculated via an interpolation between the two algorithms. This provides a more accurate measure of equivalent bandwidth and thus facilitates efficient use of network resources.
