Satellite specific protocol issues – Network layer protocols
Header compression (HC)Problems with HC as specified in RFC 1144 (does only support IP/TCP traffic)
IPv6 support in HC as specified in RFC 2507 and ROHC (RFC 3095)
IP MulticastPIM-DM and PIM-SM (revised version) support IPv6
SSM, DVMRP, MOSPF, BGP-4+, and BGMP support IPv6
Proprietary multicast relay solutions for networks without multicast support often do not support IPv6 (e.g. OmniCast)
IPv6 MultihomingLarge global IPv6 address space
Mobile IPv6 and HIP (Host Identity Protocol) support IP addresschange during ongoing sessions
IPv6 Multihoming can be done more efficient

Satellite specific protocol issues – Transport layer
Enhanced TCPEnhanced TCP protocols like TCP Tahoe, TCP Reno, TCP Vegas, TCP New Reno and TCP Santa Cruz operate above IPv4 and IPv6
PEPProtocol Enhancing Proxies (PEPs) are standardized in IETF for both, IPv4 and IPv6
Some PEPs (TCP splitting) break end-2-end transparency:
" IPv6 assumes end-2-end transparency
" IPsec support mandatory in IPv6
" Hence, IPv6 could be affected more severe
PEP devices available mostly do not support IPv6, and hence, TCPover IPv6 traffic mostly cannot be enhanced

IPv6 support in MIBs:DVB-RCS-MIB: Several objects of type IpAddress (32 bit)Proprietary MIBs use IpAddress type: e.g. Harmonic and SkyStream

Modified service offerings – End-to-end IP addressing
Issue in IPv4:Not enough global unique IPv4 addresses availableDeployment of NAT boxes (Network Address Translation) Deployment of Application Level Gateways (ALGs)
Problem with NAT boxes and ALGs:Break of end-to-end connectivity (principle of the Internet)NAT and ALG represent a single point of failureAny application with IP address info in the payload requires an ALGALGs cannot access payload when encrypted (IPsec)NAPT has no information about related sessions (VoIP)

such as aircrafts, ships, trains, vehicles

• Allows for node authentication without key infrastructure (e.g. satellite terminals)

IPv6 audio (RAT) and video (VIC) conferencing worked fine via
satellite
Mobile IPv6 and IPsec worked fine via satellite (even together)
The Mobile IPv6 handoff time has been increased by the satellite
link in the middle (from around 3s to around 5s)
RAT and VIC both worked via an IPsec secured satellite link
VIC also has been successfully demonstrated together with Mobile
IPv6 over satellite
RAT didn‘t run on the Linux kernel version required by Mobile IPv6

IPv6 runs quite stable in SILK
Integration with existing IPv4 service had been possible withoutany problems
Training of administrator staff and user community is absolutelyrequired (mainly on ULE and IPv6 in general)
Cross-trapping service between EurasiaSat-1 East and West beam is difficult to negotiate with satellite operator
Support of 8PSK for DVB-S sender and receiver would have been appreciated
Lack of sufficient management possibilities / separation of IPv4and IPv6 management is a burden
Valuable experience has been collected due to involvement of a real, large user community

Lessons learnt
Satellite specific protocol issues
MPE encapsulation lacks native IPv6 support
IPv6 stateless address autoconfiguration won‘t work on many satellite architectures (UDLR could help here)
Proprietary functionality like PEP often lacks IPv6 support
Mandatory IPsec support could conflict with some PEP scenarios
Management functionality for most satellite equipment often lacks IPv6 support
Modified service offerings
Mandatory IPsec support allow for encryption of satellite link from hub to terminal (less conflicting with PEPs)
Larger deployment of VoIP over satellite in Asia / Middle East

Transition scenarios
Introduction of IPv6 should be done in a dual-stack way
Non IPv6 ready parts (e.g. DVB-S links) should be tunnelled
Finally missing IPv6 functionality should be added by manufacturer
Demonstration
Setting up ODG based ULE encapsulator worked straightforward
Setting up Pent@Value based ULE receiver is sensitive to Linux system configuration
Pent@Value solution doesn‘t support 8PSK (however, ULE is now part of Linux kernel and should therefore work with more DVB-S receiving cards)
Once configured, ODG and Pent@Value receiver run stable
Advanced IPv6 functionality like security and mobility support runs smoothly over satellite (increased handoff delay)
Lessons learnt – continued

Recommendations – Product enhancement
Add missing functionality to satellite products
ULE support for DVB-S sender and receiver, alternatively extension of MPE to support IPv6
IPv6 support for management systems
IPv6 support for PEPs
Thinking the future

Recommendations – Standardisation
IETF ipdvb WG
Finally standardize ULE
Work on more dynamic address resolution mechanisms (for IPv4 andIPv6)
ETSI DVB
Clarify the distinction of IPv4 and IPv6 packets carried in MPE without using LLC/SNAP
ETSI DVB-RCS
Push / investigate the combination of forward and return link into one logical interface
Add full IPv6 support to DVB-RCS MIB
Thinking the future

Recommendations – Deployment
Deployment in R&D projects
ESA „IPv6 over Satellite“
EC „SATIP6“
NATO „INSC“
Deployment in „pre-commercial“ projects
SILK project
WIDE project
Offering of commercial services
Service offering on Teleports
It’s time to start with “IPv6 over Satellite” deployment
