“Embedded Switching System”: Requirements • • • Scalability of System Size Linear Scalability of Cost with Number of Ports No Cost Offset Scalability of Service Architecture Decentralised Signalling and Switch Control “Graceful Degradation” Behaviour in Case of Faults Philips Research Aspen Technology Summit-21. 05. 98 Page: 7 P

Functional Partitioning 1/3 Port. Function Switch Function Port. Function Control & Man. -Function Observations: • The Port Function is becoming increasingly complex (z. B. by ABR) • Traditional Switch Concepts have too little Flexibility to support additional new services (e. g. Processor Speed problems) • Switches are optimised on Throughput and not on Network operation Philips Research Aspen Technology Summit-21. 05. 98 Page: 8 P

Conclusion • Low Cost ATM is not only feasible but already available (CMC concept) • The distributed CMC-Concept allows the extension to WATM • The building block approach of the CMC concept supports the stepwise extension towards full AD-HOC WATM systems • A first CMC based WATM demonstrator has been implemented (10 Mb/s) • First application will be in the office environment • The final goal to support IHDN is in reach Philips Research Aspen Technology Summit-21. 05. 98 Page: 25 P
