General Internet Service
• The General Internet Service is the connectivity between the
Nordic research networks and the General Internet.
• NORDUnet provides it in two ways
– Peering with IP providers, mainly in Stockholm (20% of traffic)
– Purchase of IP Transit from IP providers (80% of traffic)
• Earlier, NORDUnet connected to IP providers in USA and
used its own transatlantic links, but in 2001 it was changed to
a local connection in Stockholm to KPNQwest’s IP network,
because
– it was cheaper, being at the beginning of a dramatic price
decrease of IP transit services
– it was technically safer, because of more physical redundancy in
the networks
NORDUnet 2003 8
but …….
• it turned out to be extremely unsafe because of the lack of
viability of the provider
• On 31 May 2002 KPNQwest filed for bankruptcy and the fate of
the 2Gbit/s service became uncertain
• However, NORDUnet was lucky because a 2.5G backup connection
under implementation to KPNQwest in Copenhagen could be
connected to Sprint International in Copenhagen within a few days
and became operational on 30 May 2002 as the KPNQwest
troubles were anticipated some time before the bankruptcy
• and on 6 June another 2.5G connection was set up to Telia in
Stockholm with the local loop delivered in 7 days
• As a result continuity of service was assured, and NORDUnet
could use the rest of the year to normalise the service situation
by issuing a new call for tender
NORDUnet 2003 9
and today …..
• NORDUnet has learned the lesson and has two providers of
IP transit service, each connected over two 2.5G ports (3
ports in Stockholm and 1 port in Copenhagen)
• The arrangement gives local and global physical redundancy,
as well as fall-back options in case of commercial trouble
NORDUnet 2003 10
Connection to USA research
• October 1988: 56 Kbit/s satellite link to Princeton
• 1991-1997: NSF ICM programme
– From 128K to 50M
• 1999-2003: NSF HPIIS programme
– Separate commercial and research connectivity
– Connect to Startap
• August 2003: Terminate NORDUnet’s own 622M link to
USA and use GÉANT for the services, because
– GÉANT has become well connected to USA networks
– Abilene provides intercontinental transit
– service is embedded in GÉANT subscription fee
• A big Thank You from NORDUnet to NSF, Abilene, ESnet,
vBNS, Canarie and SINET, for this long-lasting direct
connection
NORDUnet 2003 11
Forskningsnet
• Upgrading from 622Mbit/s to a 2.5 Gbit/s ring structure:
– Copenhagen-Odense-Århus-Aalborgand back via Göteborg to Copenhagen
• Network research
– setting up a Danish national IPv6 activity
– dark fibre through the country
• GE channels
• experimental equipment for 10GE channels
• No central funding in 2003
NORDUnet 2003 12
FUNET
• Business as usual (upgraded to 2.5G already at previous
conference begin 2002)
• Accesses upgraded form 155M to 622M and GE
• Upgrading backbone routers to 10G capability
NORDUnet 2003 13
RHnet
• GE ring in the Reykjavik area and 10-100M links to outside
• NORDUnet connection over CANTAT-3 sea cable upgraded
to 155M in Jan 2003
• No back up of NORDUnet connection
• RHnet back as Iceland member of Terena
• No central funding
NORDUnet 2003 14
UNINETT
• Network upgraded to 2.5G between major universities, based on a
15 year IRU with cost based further upgrades
• FEIDE middleware project progress towards a common electronic
identity towards different services. Collaborate with the Nordic
GNOMIS initiative
• UNINETT is expanding to more services and organisations:
– UNINETT and NTNU collaborate in centre of excellence: “Centre for
Quantifiable Quality of Service in Communications Systems” (Q2S). 35
scientists for next 10 years.
– A subsidiary, UNINETT ABC, has been tasked by government to define
strategy and architecture and operational solutions for networking schools
in Norway
– UNINETT and SINTEF will set up a national centre for Information
Security
NORDUnet 2003 15
SUNET
• 10G resilient nationwide network since Nov 2002
– all 32 universities have 2.5G access
• End-to-end performance between GE ports over production IP
networks :
– 960Mbit/s over 1000 km SUNET in Sweden
– 970Mbit/s over 14600 km SUNET-Sprintlink between SUNET and
Sprint at San Jose
• Production type support for netbased meetings
• Active participation in SweGrid, Swedish Grid Initiative
• Launched extensive study of actual usages of SUNET
– user interviews
– technical measurements

Upgrade to 10 Gbit/s
• Why 10G now?
–

–
–
SUNET backbone is 10G
Other Nordic networks are upgrading
GÉANT is 10G
NORDUnet must not be a bottleneck
GRIDs are coming
• But …..
– 10G equipment is expensive
– Cost includes one time investment that puts high demands on
NORDUnet’s cash flow
• So …..
– Spread the upgrade over 2 years to alleviate effect on cash flow
– Backup at 5G only to reduce new equipment cost

NORDUnet “lambda” actions
• Events
– StarLight and NetherLight developments with European
participation by SURFnet, CERN, CSnet, UKERNA
– GARDEN project proposal
– GRID users’ demands
• NORDUnet (alias Nordic network research) wants to
participate in developing this technology, and NORDUnet
will
– build a Nordic “lambda” infrastructure
– connect it to NetherLight in Amsterdam
– use it for 6NET and GARDEN, too

Trends
• Research networking:
– build for peak load
– use GÉANT for intercontinental connectivity
• Network development:
– increase activities
– act as Nordic platform
• General Internet connectivity:
– beware of provision stability
– traffic growth flattening out?
Prepare for the GRID
