An Enhanced Framing Strategy for Jitter Management

The Internet protocol´s best-effort service is ill- suited for delivering real-time, interactive applications such as voice. Additional management is needed to maintain quality at satisfactory levels throughout the duration of the call. A new framework at network management, the value-based utility model, uses the knowledge of user satisfaction levels in order to allocate resources more efficiently. Our research applies the value-based utility model to jitter management and demonstrate that performance improvements can be achieved by enhancing on the frame-based scheduling algorithm Stop-and-Go. Our results show that Stop-and-Go with utility can achieve a tighter jitter bound of T, where T is the frame length, which is half of the original bound of 2T offered by Stop-and-Go alone.
