Greetings,
This is not exactly TCP/IP, but related. We are looking for
some design information for Fiber Optic Ethernet equipments. One
feature that we have seen that has a great deal of appeal is
Collision Avert whereby two packets arriving at the star simultaneously
do not annihilate each other. With this feature, the first packet
always gets out, all other transmitted packets get the standard
collision signal. With this feature, supposedly, the Ethernet will
not saturate at the usual 40-62% of 10Mb/s throughput.
We would like to get in touch with everyone on this list who has
had experience with any/all equipments that use Collision Avert on
a Fiber Optic Ethernet. We are particularly interested in the results
of any controlled studies that measure performance, both with CA and
without CA. And, if statistics are available that provide for
predicting overall throughput as the load increases.
Also, we would like the names of companies whose equipments
provide for the Collision Avert feature.
Thanks in advance. And, if there is interest, I can summarize
for the list.
Respectfully,
Ted Calkins ( ted@NADC.ARPA )
