Value-Based Utility Broker for Jitter Management of Voice on IP Networks 2.0 Researcher

Internet Protocol (IP) is a best-effort technology that does not provide any guarantees on service quality. Data can arrive at the receiver delayed, out of sequence or not at all. This lack of reliability in service poses a great challenge for delivering real-time, interactive applications. In particular, voice has certain requirements that make it highly sensitive to packet loss, delay, and variation in delay (jitter). In order to offer Voice over IP (VoIP), a management scheme must be employed in order to maintain the quality at satisfactory levels throughout the duration of the call. This scheme should give preferential treatment to voice traffic without greatly penalizing the other applications. A new framework at network management, the Value-Based Utility (VBU) model, uses the knowledge of user satisfaction levels in order to allocate resources more efficiently. This research aims to design a Value-Based utility broker that can manage voice calls on local and single-hop IP networks. Using the value-based utility model, the broker will optimize perceived jitter of voice packets without sacrificing the performance of the other non-voice traffic
