Outline Introduction Evolution of cable communication systems in European cable networks Experience with Euro-DOCSIS MSO requirements for future service provision 03.06.2004

Introduction EuroCableLabs Migration tComLabs Euro-Cable Certification Board ECCA Technical Committee cooperation European Cable MSOs Certification of cable communication equipment (Euro-DOCSIS, Euro-PacketCable, ...) Certification testing on behalf of Certification Board Emerging technologies and standardisation 03.06.2004

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

Adapt DOCSIS to Euro-DOCSIS American standard: DOCSIS Data Over Cable Service Interface Specification Adaptation to Physical properties of European CATV networks European frequency allocations Downstream Annex A of ITU-T J83 European standard: Euro-DOCSIS 03.06.2004

Euro-DOCSIS versions Euro-DOCSIS 1.0 Euro-DOCSIS 1.1 Euro-DOCSIS 2.0 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 03.06.2004

Euro-DOCSIS standardisation Euro-DOCSIS 1.0, 1.1, and 2.0 are 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 03.06.2004

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. 03.06.2004

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 03.06.2004

Euro-PacketCable - Telephony over cable First commercial deployments and plans for commercial deployments Switzerland Sweden Belgium Germany others Trials in various European countries 03.06.2004

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 03.06.2004

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 03.06.2004

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 03.06.2004
