The dichotomy • Networking is simple - all users know what they want. (Fast, reliable, ubiquitous, lots of good services, and cheap) • It is only making this happen (internationally) which is hard
My two favourite themes (in this context) • The engineering costs of under-ocean bandwidth are inherently high. The distances are long, the engineering is much more complex than for over-land lines, and there are far fewer fibres on any given route. The engineering costs are 10-20x higher than overland. This ratio is staying constant as the technologies advance. • We have no sensible and/or serious mechanism in place for managing the upgrades of “public interconnects” (routing default traffic).
Defining the community • The perceived quality of a network depends closely on the community that is trying to use it. Such as:- • universities, research organisations of all types, molecular biologists, schools, homes, commerce, …. • Until you define your community, and the geographic scope, you don’t know what you want to optimise. • National definitions vary.
Access to fibre • All the signs are that serious progress on the GIBN (Global Interconnectivity of Broadband Network) front will depend on global access to fibre. • If we are serious we should make a credible presentation to a few fibre owners, asking for very cheap fibre world-wide for ~5 years. Project Oxygen, Global Crossing, and Worldcom MCI might be good places to start, but we should talk to any serious supplier willing to talk to us.
In the meantime….(for Europe) • Europe should especially foster collaborations with countries and/or regions who have interesting technologies and/or understand what cost-sharing means • 155 Mbps shared by Europe to Canada could/would be very interesting • And Europe needs to improve its connectivity to Japan, where cable connections going “directly” rather than via the USA should now be viable.
Things are not perfect (yet!) • Lots of good connectivity exists • And lots of very poor connectivity (even in the USA/N America) • Support efforts to measure and understand the Internet better • Let’s be honest about some of the packet loss and jittery delay that users see!
Fermi to Brown (15 April to 25 August) ?? Packet loss 16.15% in April, 0.05% in July. They changed their ISP!!
Routed via Washington, Dallas, Washington, NY(EUnet), NY(Qwest), Denver
Finally • Are we serious?? • If not, let’s not waste time • If we are, let’s start investing seriously in people and money for GIBN activities. Providing what the users know that they want is far harder than we are sometimes prepared to admit. • The problem is not with the technology, but finding enough effort to organise the politics and economics of international collaboration.
