Patent ID: 7586923

Claim:
A method comprising: determining a frame relay data rate R FR for a Voice over Internet Protocol (VoIP) call based on a packetization time interval T S and its associated sample data size B S for a particular coder-decoder (CODEC), a size B HT of at least one of a frame relay header and a frame relay trailer, and a size B IP of at least one header in an IP packet for the VoIP call; determining a number of VoIP calls NUM VOIP that can be supported by a frame relay access link based on a bandwidth of the frame relay access link that is to be allocated to VoIP traffic and the frame relay data rate R FR , wherein the bandwidth of the frame relay access link that is to be allocated to VoIP traffic is a product of a bandwidth B RF of the frame relay access link and a predetermned fraction R P of the bandwidth of the frame relay access link that is to be allocated to VoIP traffic; determining at least one network parameter based on NUM VOIP ; and allocating bandwidth in an asynchronous transfer mode (ATM) network for the VoIP traffic based on the at least one network parameter.
