Context-aware quality of service control in session based IP networks

Context-aware QoS control in session-based IP networks is proposed. This work proposed the basic architecture and algorithm of context-aware SIP-QoS server that can control QoS for each session or media stream, based on context information including IP flow information, media type, user presence, and user preference. QoS applications with context-aware QoS control in session based networks are also proposed.
