Status Review
3NML Weekly SeminarSchool of Info. and Mech., Networked Media Lab., Dong-Hoon Yi
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
