  1. PacketCable Project Terry D. Shaw, Ph. D. CableLabs 303-661-3811 t.shaw@cablelabs.com

  2. Overview • Service concept • Project structure and timeline • Interoperability Testing

  3. Characteristics of Cable’s High-Speed Data Service • Always on / Always connected • Speed scales depending upon need • High speed > e.g. Internet Access • Low speed > e.g. Telemetry • Medium speed > e.g. Telephony • Streaming / Isochronous more difficult

  4. Integrated Services Network DATA VIDEO Downstream • Analog & Digital Broadcast • Video on Demand • Other Video Control Upstream DATA

  5. Voice Telephony Local LEC Bypass Long Distance Video Telephony Other Services Over “Telco Circuit” PBX Extension Fax PLUS Service Concept Initial Services: Subsequent:

  7. PacketCable™ Concept • Packet-based applications running over nationwide mesh of cable and backbone IP networks • Hop off data network to PSTN only as last resort

  8. PacketCable™ Concept (cont’d) Applications Specification effort focuses on applications layer software and hardware components Network Transport Physical

  9. Project Objectives • Develop overlay packet network for cable systems • Support broad family of services • Open, interoperable standards for North American cable market • Initial focus on IP telephony and video • Described in Product Definition Statement

  10. Project Overview • Four focused areas of effort • Product definition • Technical specification/reference architecture • Product testing • Information sharing

  11. Product Specification Working Group Objectives • Translate product definition statement into functional/technical requirements • Develop reference architecture/technical specification necessary for implementation • Identify timeline for phased approach • Communicate functional requirements of industry to vendor community • Build on existing standards

  12. Product Evaluation • Goal: Laboratory testing of IP products • Performance across cable systems • Technology validation • Identify and specify key quality parameters • Interoperability • Timeline: • Experiential: November 1997 - June 1998 • Interoperability: March 1998 - December 1998

  13. Fast-Track Performance Validation • Basic system operations: “Does it work?” • Validation of protocol interoperability • Test key parameters under stressed conditions • Traffic loading and latency issues • Network integrity • Quality of Service (QoS)
