  1. Architecture of the Flexinet ForCES-based Control Point Robert Haas, IBM Research, Zurich Research Lab, rha@zurich.ibm.com Toshiaki Suzuki, Hitachi, Central Research Laboratory, toshiaki@crl.hitachi.co.jp IETF ForCES WG meeting, Paris, Aug 1, 2005.

  2. FlexiNET: Overview • STREP @ “Broadband for all” (Specific Targeted Research Projects) • Started March 01, 2004, duration 2 years • www.ist-flexinet.org • 8 partners • Main objective:to accelerate the introduction of next-generation marketable services, and increase competitiveness in the telecom field by facilitating the broadening of current business models for services provisioning and exploitation. • Get data out of the Network elements (Data Interface and SAN) • Use a service-centric architecture for new applications (Applications Interface) • Move services and switching management towards the network edges (GW) • Add service programmability

  5. FlexiNET: FWAN FWAN CE Extensible Function Block Basic Function Block (PC) Host PC CPU RAM(Table) CE FE 100Base-TX (NP Development Kit) I/O RAM(Buffer) Bridge CE PCI NP FE Core CPU RAM (Buffer) Micro Engine Micro Engine GbE Switch RAM (Table) GbE I/O I/O I/O I/O WLAN AP To Generic Application Interface Router To Internet GbE: Gigabit Ethernet

  6. FWAN ForCEG requirements • ForCEG maintains NE-wide consistency while various services configure the FEs. • Services declare their consistency req’s • Checking is done at LFB, FE, and NE levels. • ForCEG demultiplexes responses to the originating service QoS AAA Proxy ForCEG CE CE FE FE FE

  7. FWAN ForCEG architecture • MCP are services such as AAA Proxy, QoS, etc.

  8. Implementation • Dynamic Service Deployment implementation (in progress) based on • OSGi for remote code starting/stopping • Webservices for flexible loose coupling with services • GT4 Resource Discovery • Matchmaking algorithm for optimal resource allocation • ForCEG implementation in Java (in progress) • ForCES CE implementation in Java (in progress)

  9. End

  10. FWAN ForCEG adaptability • ForCEG offers Service API modules that match Service requirements AND underlying FE capabilities. QoS AAA Proxy API API ForCEG CE CE FE FE FE
