  • Introduction

  • Evolution of cable communication systems in European cable networks

  • Experience with Euro-DOCSIS

  • MSO requirements for future service provision

  • 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

Euro docsis versions l.jpg

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

Euro docsis standardisation l.jpg

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

Euro packetcable l.jpg


  • 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.

  • Specifications based on PacketCable developed by CableLabs

  • Differences for Europe

    • Handset interfaces

    • Class features

    • SS7 differences

    • V5.2

    • Electronic surveillance

    • Root Certificate Authority

Euro docsis large scale deployment l.jpg

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

  • First commercial deployments and plans for commercial deployments

    • Switzerland

    • Sweden

    • Belgium

    • Germany

    • others

  • Trials in various European countries

View into the future l.jpg

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

View into the future cont l.jpg

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

Summary l.jpg


  • 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
