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. 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

7. 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

8. 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

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.

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 Mbps downstream
typically 128 kbps upstream
volume-based, time-based usage limits
Service take-up in some regions in Europe e.g. Belgium
30% % 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
