A stable network for application 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/NORDUnet
Where and how http//drift.uninett.no/kartg/last
/uninett/norden Backbone STM1 to STM16 in near
future.
5
A separate test bed for network technology
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 RD, FFI).

6
Areas 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

7
Project activities.

• UNINETT, IPv6 backbone.
• To study backbone construction and management
• UNINETT, Lab.
• To study applications and network services.

8
UNINETT, IPv6 backbone.

• 4 Cisco 4700 router running latest IOS IPv6 Beta
  based on IOS 12.1.
• BGP4 tunnel peering with 6bone and NTT.
• Native peering with QTPv6.
• Interopability tests.

9
UNINETT, lab.

• Tunnel Broker, lets anyone connect workstations
  via tunnels. Some 30 tunnels
• 6to4, automatic tunnels
• DNS (bind 9.0.0), IPv6 enabled, A6 and DNAME rec.
• Web Cache, accelerator
• OpenLDAP
• IPv6 enabled workstations
• Multihoming
• Wireless LAN

10
QTPv6

• Quantum Test Program, test bed network on TEN-155
• IPv6 addressing policies
• Multihoming
• DNS
• Applications
• Interoperability
• Initial report delivered

11
IPv6 Host plattforms

• IPv6 Solaris 7 and 8
• Redhat 6.x
• FreeBSD 3.4 and 4.0
• Windows NT and 2000
• Compaq IPv6 stack for Alpha/Tru64
• IBM AIX 4.3

12
IPv6 Router plattforms

• Telebit TBC2000
• Cisco IOS 12.1
• FreeBSD 4.0 (KAME stack)
• Zebra (GNU router project)
• 3Com Netbuilder II, software v11.3
• Hitachi NR60 (Gated)

13
IPv6 Applications

• Apache web serve
• MSIE web browser
• plus Mozilla and Lynx
• Sendmail 8.10
• IRC, Mbone tools, INN, ...
• Quake

14
IPv6 Addressing

• IPv6 addressing scheme
• -20010620/35 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?

15
IPv6 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

16
IPv6 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

17
IPv6 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

18
IPv6 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

19
Transition/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, ...

20
Project activities, cont.

• UiTo, computer science department.
• Native IPv6 only lab.
• IPv6 DNS, FTP proxy etc. (KAME)
• IPv6 NAT.
• Native IPv6 only lab. PASTA, different aspects of
  private machines in distributed systems, in
  cooperation with Univ. of Pisa.
• Vermicelli (VERy MobiLe Clients Enhanced for Link
  Level Interaction ). Integration of mobile
  machines into a static IPv6 infrastructure.

21
Projects, UiTo PASTA
22
Project activities, cont.

• NTNU
• IPv6 enabled test network on campus.
• UNIK
• Distributed Multimedia Systems
• FFI
• NATO related experiments.
• NR
• IMIS, Infrastructure for Multimedia Applications
  in seamless Networks.

23
Project activities, cont.

• UiO
• MMCL Multimedia Communication Lab.
• Wireless Mobile IPv6, (Weman).

24
Conclusion - 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

25
Conclusion - 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

26
Other activities.

• Quantum Test Program Diffserv by TEN-155.
• BOF on testbeds Friday 1600 room 24.
