1. European FP6 Project: Satellite Access Technologies: Leading Improvements For Europe (SATLIFE) Project IPv6 Activities Dan He Haitham Cruickshank Zhili Sun 09 June 2004

2. Agenda Project Overview Satlife Consortium Project Objective Current Satellite Architectures Project Key Issues Contributions to Standards SATLIFE plan for ipv6 inter-domain multicast SATLIFE plans for transition from IPv4 to IPv6

3. SATLIFE Consortium(13 partners) EMS(UK) UNIS(UK) Alcatel (FR) Thales B&M (FR) Hispasat(ES) ALCATEL SP(ES) Telefonica(ES) DIT-UPM(ES) INDRA(ES) NERA(N) SHIRON(Israel) TELEMAR(Brazil) Telefonica R&D(Brazil) Project Workload 85PY in total

4. Project Objective Development of low cost access network DVB-RCS systems for transparent and regenerative satellite solutions in order to ensure the availability of broadband for all. Launch mid-2004 High Quality Multimedia Interactive Services Four spots: North America, South America, Brazil and Europe Amazonas Satellite: 1 st multimedia OBP

5. Current Satellite Systems Access Network Architectures DVB-RCS architecture: 2-way multimedia IP based DVB-S forward link MF-TDMA return link MPEG segmentation Packet based DAMA Regenerative Satellite architecture (RSA): Multi-Gateway Mesh: direct ST-to-ST On-board switching DVB-S downlink DVB-RCS uplink

6. Project Key Issues QoS issues in regenerative satellites: Only pure physical/access layer standards (DVB-RCS). DVB-RCS is based on IPv4 and the project has dedicated this issue No QoS support definition for satellite system. IPsec issues: Problems with Performance Enhancing Proxies (PEP), multicast and NAT Interworking issues in satellite/terrestrial integration. Multicast issues over DiffServ/MPLS. Network management issues: No MIB definitions

7. Contributions to standards Contributions to ESA SATLAB: Interoperability, ODU, IDU, installation Contributions to DVB Standard: DVB-S2, DVB-RCS,DVB-TM, DVB-CM, DVB- IPI Contributions to ETSI-TC-SES/BSM: Multicast, IP, QoS, services, Addressing

8. SATLIFE plan for IPv6 inter- domain multicast For SATLIFE project, IPv6 and multicast remain areas of on-going research ( IETF: draft-savola- v6ops-multicast-issues-03.txt ). Due to multi-domain nature of satellite systems, global IPv6 inter-domain multicast is impossible. There is no way to convey information about sources between PIM- SM RPs. Source-Specific Multicast could be a solution without RPs and can be communicated out-of-band. SSM is far from being generally implemented, much less deployed

9. SATLIFE plans for transition from IPv4 to IPv6 The transition from IPv4 to IPv6 and co-existence of IPv4 and IPv6 is a subject of much debate (IETF: draft-savola-v6ops-transarch- 03.txt ): Currently we are at the early stages of the transition Deployment models for IP nodes can be: IPv4-only Dual-stack with only IPv4 connectivity Dual-stack with IPv4/6 connectivity Dual-stack with only IPv6 connectivity IPv6-only SATLIFE project will continue to monitor the IPv6 deployment in Europe: A study will be conducted on the IPv4/IPv6 transition and interworking.
