We've also been looking at Web prefetching, using server-side

References are listed on our Web pages:


	"Defining 'High Speed Protocols, Five Challenges & and Example
	That Survives the Challenges," J. Touch, IEEE JSAC Special
	Issue on Applications Enabling Gigabit Networks, Vol.  13, No.
	5, June 1995, pp.  828-835.

	"An Experiment in Latency Reduction,", J. Touch and D. Farber
	IEEE Infocom 1994.

We found that server speculation would decrease latency by 2/3, to 0.7
RTT (yes, below the speed of light) by increasing the BW by 7x. Note
that this RTT is an average per page - it still takes 1 RTT for the
first page...
