Quantifying Improvements from Refinements in a VoIP Teleconference System

In a VoIP (voice over Internet protocol) telephone system, we face the significant challenge of providing a teleconference feature that can support a large-scale teleconference without using excessive network bandwidth. This paper examines a new, bandwidth-efficient way of implementing a real-time VoIP teleconference system, and we present measurements of the improvements that we gained by refining our original concept. Our newly refined teleconference technique provides all of the features that previous teleconference systems provide, but our new approach consumes considerably less data bandwidth than previous systems require. The new system allows a network with a given capacity to accommodate nearly double the number of conference participants that an existing system would allow.
