I'll appreciate very much if somebody could point me to references
(RFCs, conference papers, journal papers, tech reports, etc) which
support the following observations:
(Of course, these observation were made on this bboard in some or the
other context, but I was not able to keep track of references.)
1. Network protocols, such as TCP/IP are integrated in operating
systems in such way that the maximum achievable throughput out of these
protocols is less than 1 Mb/sec. In other words, even in a loopback
situation, the maximum throughput is limited to a number like 1
Mb/sec.
2. Given a very high speed communication subnetwork (of the order of
100 Mb/sec) and applications which can use such high bandwidths, it is
not clear if TCP/IP architecture would be appropriate for such an
environment.
3. How much of "less than optimistic" performance of today's INTERNET
can be attributed to the fact that it has
a. links which still operate at low speeds, such as 9600 baud
b. multiply connected subnetworks
Thanks!

Dear Sir/Madam: I am looking for discussions/references that happened approximately 1 - 3 years ago that debated the pros and cons of using a fixed Vs variable packet length in high speed packet switches. In particular I am interested in their effect on switch to switch synchronization and also the implications on queue/buffer sizes. References or text including those debates would be greatly appreciated.
