2 France Télécom R&D © France Télécom - D2 - 23/02/2014 Presentation Overview è VTHD project project objectives, applications VTHD network è Introduction of IPv6 in VTHD phase 1 deployment IPV6 roadmap è The Evolution of VTHD IPV6 IPV6 in VTHD++
3 France Télécom R&D © France Télécom - D3 - 23/02/2014 è Project objectives To experiment optical internetworking To develop new applications and to ensure that they can be put in use in the broader global Internet. to assess scalable capacity upgrading techniques to assess traffic management tools necessary to operate a QoS capable test-bed To deploy and operate a high performance network that provides high capacity interconnection facilities among laboratories at the IP level. VTHD Project è Project framework Partially french government funded project (initiative for research on networking technologies) : RNRT (Réseau National de la Recherche en Télécommunications). Partners from the academic world. European extensions/connections through IST projects were fostered. The VTHD project ended in december Follow-up VTHD++ project will cover years 2002 and 2003.

11 France Télécom R&D © France Télécom - D /02/2014 VTHDv6: IPv6 roadmap Phase 1: Q2-Q4 2001: Was only a first step of IPv6 connectivity service (IPv6 edge router / tunnelling interconnection (MPLS or IPv4)) Phase 2: Q Q2 2002: Start of introduction of IPv6 in VTHD backbone: dual stack approach on some gigarouters: toward an IPv6 capacity of 800 Mbit/s. Tunnelling: Efficient IPv6inIPv4 tunnelling (to bypass non IPv6 gigarouter) Study of IPv6 over MPLS without overheads (Cisco 6PE, …) Phase 3 : VTHD++ (follow-up of VTHD) Q …: availability of IPv6 links (dual stack) up to 2,5 Gigabit/s IPv6 over MPLS (6PE, …)

13 France Télécom R&D © France Télécom - D /02/2014 VTHDv6 recap Phase 1 to 3 are focusing only on IPv6 connectivity service (with high speed aspects) Future work will treat other aspects: IPv6 services should be (almost) equal to IPv4 services Multicast, VPN, CoS,… Or more IPv6 specific services: Transition services, DNSsec,… Before the end of VTHD++ (December 2003): VTHD IPv6 network topology should be the same as IPv4 network (dual stack for all the nodes).
14 France Télécom R&D © France Télécom - D /02/2014 VTHD++ IPv6 WG: objectives / partners VTHD++: follow-up of VTHD ( ) agreed by RNRT Working-Group 3: IPv6 trials Objectives: getting an experiment of sharing an infrastructure (VTHD) for IPv4/IPv6 networks offer new services to (with) our partners (particulary involved in IPv6 developments: research, standardization) run new IPv6 applications (which require bandwidth) on a nation-wide IPv6 network getting an experiment of a high-speed (beyond 155 Mbit/s) IPv6 network deploying a RNRT platform useful for future mobile service trials Partnership of this WG: ENST, ENST-Bretagne, INRIA, FT R&D (leader of WG) and the new partner IMAG ( M athematical high engineering school in Grenoble)
