- *Abstract
-
Voice packet delivery over the Internet still relies on the best effort service model, in which quality of service cannot be guaranteed. In terms of end-to-end delay, as a significant parameter of voice quality, the Internet causes large variable delay. Proposed network-oriented solutions for reducing end-to-end delay are the reservation protocol and differentiated service. But, these solutions have deployment problems that hinder practical implementation in today's network environment. For a given scenario, like today's Internet, it is possible that the end systems can play a role in improving end-to-end delay. Since voice encoders generate their output at a constant rate, the delivered quality of voice packet transmission is often degraded due to inadequate available bandwidth from network congestion. The proposed solution enables the sender to adaptively transmit voice packets, using any constant rate voice encoder. Thereby, the sender can avoid network congestion and reduce (even, minimize) end-to-end delay.Non Provisional Patent Application Filed
