Advent of Emerging Apps Need Quality of Service

QoS Technologies Actually linked with the bandwidth management

problem and requires a careful design of control mechanisms so that they cover all time-scales

Cost-effective bandwidth management, Need an integrated framework in which these

mechanisms sophisticatedly co-operation with each other

Goal: design and develop a bandwidth management model for efficient utilization of a given network bandwidth and QoS guarantee in QoS-aware IP network

Design focus: high bandwidth utilization and QoS guarantee, Balanced optimization and scalability issues
