  1. Full Service Deployment via TV Broadband Networks -System Evolution Based on MSO Experiences and Requirements Malcolm Taylor (ECB)Luc Martens (tComLabs)Dirk Jaeger (ECCA) draft version

  2. Outline • Introduction • Evolution of cable communication systems in European cable networks • Experience with Euro-DOCSIS • MSO requirements for future service provision

  3. Introduction EuroCableLabs Migration tComLabs ECCA Technical Committee Euro-Cable Certification Board cooperation European Cable MSOs Certification of cable communication equipment (Euro-DOCSIS, Euro-PacketCable, ...) Certification testing on behalf of Certification Board Emerging technologies and standardisation

  4. Euro-DOCSIS & DOCSIS • DOCSIS: Data Over Cable Service Interface Specifications • Standards • DOCSIS 1.0: Data service over cable • DOCSIS 1.1: QoS for multimedia services • Euro-DOCSIS 1.x: European derivative • Uniform, consistent, open, non-proprietary, multi-vendor interoperable basis • SCTE maintains DOCSIS 1.0 standard • Access platform for other CableLabs standards • PacketCable for Multimedia services • OpenCable for iDTV services

  5. Adaptation to • Physical properties of European CATV networks • European frequency allocations • Downstream Annex A of ITU-T J83 Adapt DOCSIS to Euro-DOCSIS American standard: DOCSIS DataOverCable Service Interface Specification European standard: Euro-DOCSIS

  7. Euro-DOCSIS versions • Euro-DOCSIS 1.0 • Lightweight standard for best-effort internet • Euro-DOCSIS 1.1 • Offers QoS + enhanced security • Uses SNMPv3 for management (security + authentication) • Uses PKI (Public Key Infrastructure) for authentication and security • Basis for packet-based services such as VoIP over cable • Euro-DOCSIS 2.0 • Advanced physical layer using Advanced-TDMA and S-CDMA

  8. Euro-DOCSIS standardisation • Euro-DOCSIS 1.0, 1.1, and 2.0are official annexes to the CableLabs DOCSIS 1.0, 1.1, and 2.0 specifications • (Euro-)DOCSIS specification has been published as ETSI (European Telecommunications Standards Institute) and ITU specifications

  9. Euro-PacketCable • Goals of Euro-PacketCable - IPCablecom*: • Provide packet-based voice, video and other high-speed multimedia services over the HFC network. • Build on the QoS capabilities of Euro-DOCSIS. • Design architecture that allows multiple vendors to rapidly develop low-cost interoperable solutions to meet time-to-market requirements. • Scalable network for millions of subscribers. • Use approved and widely adopted protocol standards. * ITU name for PacketCable and Euro-PacketCable.

  10. Euro-PacketCable • Specifications based on PacketCable developed by CableLabs • Differences for Europe • Handset interfaces • Class features • SS7 differences • V5.2 • Electronic surveillance • Root Certificate Authority

  12. Euro-DOCSIS -Large scale deployment • Capacity supported by today’s systems: • 38 Mbps downstream • 10.2 Mbps (v 1.1), 40.9 Mbps (v 2.0) upstream • Service tiers provided by MSOs • 64 kbps ... 4 Mbps downstream • typically 128 kbps upstream • volume-based, time-based usage limits • Service take-up in some regions in Europe e.g. Belgium • 30% ... 40% of households with cable connection

  13. Euro-PacketCable -Telephony over cable • First commercial deployments and plans for commercial deployments • Switzerland • Sweden • Belgium • Germany • others • Trials in various European countries

  14. View into the future • (Euro-)DOCSIS service tiers offered today are not sufficient for midterm service planning • 3–5 years requirements for downstream bandwidth per user: 10 Mbps • IP service penetration forecast • 20 – 50 % medium term • almost 100 % long term

  15. View into the future (cont.) • TVoIP for VoD and video streaming • will stimulate bandwidths demand • will occupy the major portion of IP bandwidth • Traffic characteristic will change • new statistical traffic models required for maximum channel utilisation

  16. Summary • Euro-DOCSIS cable communication systems have been evolved to support requirements of European cable MSOs • Robust system with large scale deployments • Higher layer protocols for VoIP, etc. due to commercially rolled out on top of Euro-DOCSIS • Further evolution of system required to satisfy MSO demands future service provision
