Network Engineering to Support the Bandwidth Manager Architecture

Network-level behaviors can impact the determinism of call admission control decisions for a particular bandwidth management deployment. However, different network routing and forwarding models can have different impacts when used in conjunction with the bandwidth manager. We examine these models, considering their ability to provide the deterministic admission control capabilities available within the public switched telephone network (PSTN).

VoIP Introduction

VoIP uses internet protocol data packets to transfer voice, fax, and other data over the shared network, rather than the traditional public switched telephone network (PSTN), which is based on copper wires carrying analog voice data over the dedicated circuits. VoIP, in contrast to PSTN, uses what is called packet-switched telephony, whereby the voice information travels to its destination in individual network packets across the Internet that are assembled and then converted to voice.
