1
The State of High Performance R&E Networks
Aug 4th, 2001 Steven Wallace Indiana University
2
Good News (US) Internet2/Abilene connecting over 200 institutions
2.4 Gb/s backbone, still relatively underutilized Well connected to other networks (currently carrying ~5% of world-wide routes) Offering ITN service
4
Good News ((US) cont.) Production advanced services (IP multicast, QoS?, IPv6) Change in conditions of use to allow K-20, libraries, etc. Emerging Federal Lab routing policy (connection friendly, but not for inter-lab traffic)
5
Good News ((US) cont.) New Core Node in Chicago to participate in STARLight Explicit recognition of End-to-End (E2E) performance challenges (I2 spending over $1M) Expect to see upgrades to OC192 (10Gb/s) in some areas
6
Continuing Challenges
E2E performance still not solid (E2E visibility difficult) Advanced service coordination among networks difficult Getting good planning information QoS (not soup yet)
7
European News Similar to US, currently leap frog to 10Gb/s (also benefiting from fiber glut) Slightly different model (a single network provides all Internet connectivity) Key funding provided by EU (former US model) Well organized
8
Transatlantic News Dante recently offered a tender for transatlantic connectivity Wavelength based services (2.4Gb/s & 10Gb/s) Less StarTap centric 2.4Gb/s transatlantic for less $1M Euros/yr 10Gb/s transatlantic for a couple/few $M Euros/yr
9
Asia Pacific News Much more complicated
Nothing really equivalent to Dante/GEANT Internet2/Abilene More focus on IPv6 Still capacity challenged
10
Transpacific News Wavelength based services coming soon
2.5Gb/s relatively affordable (still quite a bit more than US-Europe) Less effective at coordinating transpacific purchases (still prestigious to have your own US connection)
11
GTRN (original talk) Good story for US and Europe, emerging story for Asia Pacific Great story for trans-pacific/atlantic capacity What’s missing? Global coordination of advanced services Global capacity planning Global purchasing coordination
12
What’s Needed? An inter-connecting network and organization focusing on: Global coordination of advanced services Global capacity planning Global purchasing coordination
