General Internet Service : 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
but ……. : 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
and today ….. : 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
Connection to USA research : 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
Forskningsnet : Forskningsnet
Upgrading from 622Mbit/s to a 2.5 Gbit/s ring structure:
Copenhagen-Odense-Århus-Aalborg-
and 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
FUNET : 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
RHnet : 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
UNINETT : 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
SUNET : 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
IPv6 - 6NET : IPv6 - 6NET Europe 6NET backbone
155 Mbit/s
Upgrade to 10 Gbit/s : 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
Current 2.5Gbit/s system : UiO Oslo Copenhagen Espoo Helsinki KTH Östra Vasa Cent Oslo SUNET Current 2.5Gbit/s system

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
