Supporting distributed multimedia quality of service in IP routers

Abstract

newlineIncreasing demands by multimedia applications have posed newlinechallenges on the Internet for Quality of Service QoS However the Internet newlineand the Internet Protocol IP are designed to offer equal treatment to all types newlineof traffic and provides only Best Effort service As a result there emerges a newlinestrong urge for research in network design and management to provide QoS newlineThe QoS requirements of inelastic multimedia traffic such as voice newlineand video include throughput delay jitter and packet loss This work focuses newlineon providing Quality of service to distributed multimedia applications through newlineIP router design The QoS parameters taken are packet loss and jitter The newlinedesign of the QoS architecture includes queue management and scheduling at newlinethe IP routers without any need to replace the existing IP infrastructure The newlineunified scheme with the active queue management algorithm Gentle newlineFlow based Proactive Queuing GFPQ and the scheduler Jitter Guaranteed newlineTime stamp Scheduler JGTS form the novel QoS architecture The design newlinealso leads to an innovative Internet Service Model newline
