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

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

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

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.
