A stable network for application A stable network for application research.research.

UNINETT is the network provider for the academic and research network in Norway. A stable production network. A stable research network for application research

with extra capacity, less than 30% load, to major institutions (about 30).

UNINETT/NORDUnetUNINETT/NORDUnetWhere and how:

Backbone STM1 to STM16 in near future.

A separate A separate test bedtest bed for network for network technology researchtechnology research

An IPv6 backbone based on ATM PVPs sponsored by Telenor Net, 10 - 25 Mbps. Will be replaced by STM-1. 4 native IPv6 backbone nodes:

Tromsø (UiTo); Trondheim (NTNU and

UNINETT); Oslo (UiO, NR, Thompson CSF); Kjeller (UNIK, Telenor R&D, FFI).

Areas of InterestAreas of Interest

Promote network research at the institutions IPv6 and Diffserv Deployment

studying practical issues Research

looking for Ipv6/Diffserv benefits to existing work looking for new IPv6-powered solutions

IPv6 AddressingIPv6 Addressing

IPv6 addressing scheme-2001:0620::/35 assign to ISP

though it is really a /29 allocation

- registries want only 8K routes in DFZ How to assign to HE Institutions?

- One /48 per site?- Implies 65K networks at (K ites- but "small customer" can get a /48?

IPv6 MultihomingIPv6 Multihoming

Will be more common in IPv6 Host sees Router Advertisements

- auto-configures prefix from each router May have multiple IP addresses

- so may the target host Need to choose src/dst address pair Interfaces may also (dis)appear

IPv6 RenumberingIPv6 Renumbering

Wish to switch ISP- need to use different IP prefix

Router renumbering protocol- in relative infancy- new DNS methods to support it- need to avoid hard-coded IP addresses- may also be used to deprecate a link

IPv6 DNSIPv6 DNS

Running BIND 8.x- DNS lookups IPv4 transport only- IPv6 records are AAAA records

Running BIND 9.0.0. - native IPv6 transport support- A6 and AAAA records for IPv6 DNAME

IPv6 Quality of ServiceIPv6 Quality of Service

20-bit flow label, 8-bit traffic class RSVP

- QoS per connection- e.g. Lancaster media client/server

DiffServ- QoS by packet type/tag- e.g. Thomson IP edge device

Transition/integration toolsTransition/integration tools

Ipv4/IPv6 interwoeking- NAT/PT and Ultima (BT)- Dual stack

easier if you have enough IPv4 addresses- Proxy methods

Also available- DSTM, 6to4, ...

Conclusion - technicalConclusion - technical

Ipv6 core specs are done Host and router support hardening fast

- Microsoft, Cisco and Sun on board Interoperability problems less common Interesting stuff is on the way

- IPv6 Multicast, IPsec, QoS

- IPv6 in wireless applications

Conclusion - operationalConclusion - operational

Address allocation policies important- Multihoming will offer benefits

- Renumbering has potential Auto-configuration is powerful 3GPP may provide the IPv6 kick-start Key IPv6 benefit may be scalability
