TITLE: Repairing the Internet: The Case for Detour
DATE: Tuesday, November 3, 1998
TIME: 3:30 pm
PLACE: 134 Sieg Hall
HOST: Alan Borning
ABSTRACT:
Despite its obvious success, robustness, and scalability, the Internet
suffers from a number of end-to-end performance and availability
problems, including long and unpredictable latencies for short
connections, high drop rates, low throughput for long transfers even
when
there is ample link bandwidth, poor route selection, and periods of
unavailability despite the existence of redundant paths. These problems
are not easy to fix in the current Internet; indeed, they are likely to
get significantly worse over the next 3-5 years as we increase link
bandwidth, add buffering, add links, and add load. In the Detour
project, we are attacking problems in the existing Internet by using
intelligent routers spread at key access and interchange points to
"tunnel" traffic through the Internet. These intelligent tunnels can
improve performance and availability by aggregating traffic information,
shaping bursty traffic flows, and using more efficient routes. In this
talk, we attempt to quantify the inefficiencies in the existing Internet
to argue that Detour offers the potential of an order of magnitude
improvement in latency, bandwidth, packet loss rates, availability, and
predictability relative to today's physical Internet.
Refreshments to follow.
