1. 1 Service Architecture Design for Converged Networks Blue Team Pete Broadwell, Weidong Cui, Yitao Duan, Ling Huang, Thinh Nguyen CS294-3 Spring 2002

2. 2 Motivation Characteristics of future converged networks –Heterogeneous accesses and equipments –Integrated voice/video/data services –Mobility Desired properties of new service architecture –All-IP –Interoperable –QoS guaranteed –Scalable –Flexible –Reliable –Security

3. 3 Service Architecture Application Applications supporting heterogeneous equipments and accesses across wide area Service Mechanisms needed for wide-area distributed applications Distributed Processing Control Functionalities needed for uniform communications and computations across wide area Transport End-to-end connectivity

4. 4 Service Architecture Transport Distributed Processing Control Service Application Video Conferencing Universal Mailbox AAA Composition Mapping QoS Manager Resilient Routing Gateway Measurement Discovery Resource Allocation Object Communication Online Games Scientific Computing
