Abstract

For Internet telephony to be a viable alternative to the public switch telephone network (PSTN), efficient and high quality communications are required. This paper proposes an optimization algorithm that selects parameters like the coding scheme, packet loss bound, and maximum link utilization level in a voice over IP (VoIP) network The goal is to deliver guaranteed quality of service (for voice) while maximizing the number of users served. A VoIP architecture is also discussed that could use optimization algorithms to dynamically provision VoIP networks.
