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

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

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
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)
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
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
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 ...
