Abstract
A frame relay data rate RFR for a VoIP call is determined based on a particular packetization time interval TS and its associated sample data size BS for a particular CODEC, a size BHT of at least one of a frame relay header and a frame relay trailer, and a size BIP of an IP header. A number of VoIP calls NUMVOIP that can be supported by a frame relay access link is determined based on a bandwidth of the frame relay access link that is to be allocated to VoIP traffic, and the frame relay data rate RFR. At least one network parameter is determined based on NUMVOIP. Bandwidth in an asynchronous transfer mode (ATM) network is allocated for the VoIP traffic based on the at least one network parameter.
