Performance IssuesActive Measurement Project: PC-based
machines in ~50 campus research LANs“Upper bound” results based on UDP: about
80Mbps with east/west endpoints on 100Mbps LANs
Off-the-shelf TCP performs poorly: about 6Mbps with east/west endpoints on 100Mbps LANs
Campus engineering, endpoint device tuning or engineering, and applications engineering still need lots of work!

What Do We Think? Solutions for local loop problems (availability and cost)
have been found in most cases Have finally reached a critical mass of connected sites Don’t yet have as much information about Abilene as we
do about vBNS Penetration of backbone services/functions into campus
network environments has been very limited Science-enabling performance and functionality has a
ways to go; applications stories are unclear Inter-Directorate interests are growing: telescopes, digital
libraries, biological instrumentation, Doppler radars

Opinions/ChallengesWe need much more
work at the top of the protocol stack.
Campuses need to do much more than connect.
We must not overlook the needs of network researchers.
