  1. Status update on IPv6 in CanadaCairns, 6 July 2004 René.Hatem@canarie.ca Chief Engineer

  2. CA*net 4 Objectives • provide and operate a high performance IP network in support of research and education amongst higher education institutions, government research labs, schools, etc. • provide a lightpath “customer empowered networking infrastructure” which will enable end-users to control the routing of their own wavelengths • end-users buy, establish, and tear-down their own optical links • using OON concepts • complement innovation performed in industry, as opposed to duplicate or compete

  3. CA*net 4 IP backbone, RANs, and int’l exchange points

  4. CANARIE and IPv6 • Operates CA*net4, a nation-wide layer 1 and 3 (hybrid) network • Layer 3 network piece supports native IPv6 connections to provincial R&E networks and to 6TAP since operational in July 2002 • IPv6 is a peer protocl to IPv4 in all respects • tunnels to end-users or institutions supported if native is impossible • CANARIE has co-funded a number of IPv6 projects led by Hexago (Viagénie) including creation of 6TAP and freenet6. • Hexago develops IPv6 migration broker • encourages migration of applications to IPv6, e.g. v6NNTP

  5. IPv6 value proposition • why do it? • for end users: • re-establish end-end principle of the Internet • provide more address space • eliminate need for NATs due to address exhaustion • for backbones: • dramatically aggregate BGP table • simplify address allocation and routing policy implementation

  6. IPv6 multihoming workshop • held IPv6 multihoming workshop in Montréal in May 2003, attended by • Tony Hain (Cisco) • Michel Py (IETF v6 wgs) • Jeff Doyle (Juniper) • Marc Blanchet (Viagénie / Hexago) • Guy Almes, Rick Summerhill (Internet2) • Caren Litvanyi (StarLight) • Bill St-Arnaud, ... (CANARIE) • Luc Desrosiers, Yves Boudreau (RISQ)

  7. IPv6 multihoming workshop conclusions • http://www.canarie.ca/canet4/library/ipv6.html • IPv6 hierarchical address allocation will not work in multihoming world • result: IPv6 routing à la IPv4

  8. IPv6 value proposition • why do it? • for end users: • re-establish end-end model • other solutions (hacks) • provide more address space • not yet a concern in Canada • eliminate need for NATs due to address exhaustion • but is address exhaustion main reason NATs are used? • for backbones: • dramatically aggregate BGP table • simplify address allocation and routing policy implementation • not in a multihomed world • assuming unique IP addressing for all hosts, fundamentally there is little IPv6 brings to applicationlayer that IPv4 cannot deliver

  9. status today • today in Canada, IPv6 brings little benefits , but significant costs to institutions and carriers an ISPs • progress is extremely slow • need to convince end institutions and researchers of the value • need to find value proposition for carriers and ISPs • need to get more application support • accepting all IPv6 routes in same way as IPv4 • IPv6 à la IPv4 • CA*net 4 accepts all commercial routes until such time as commercial providers offer IPv6 services commensurate with IPv4 offerings • CA*net 4 will support IPv6 multicast by end of 2004 • waiting to see what happens ...
