Some initial numbers for my isdn

[David Farber <farber@central.cis.upenn.edu>]

Some experiences are now in order . First works like a charm, I am seeing
trivial retransmits.


My Quadra is hooked up as follows:


Quadra via ethernet (10base2) to a conversion hub then ethernet (10baseT)
to a CombiNet 150 (does some compression) connected to the NT1 ISDN. The
other line in the same CO at our New Boulton Vet School near by, has a
Combinet 400 (filtering bridge) connected to the NBC ethernet. This
ethernet is bridged to a T1 which connects to our campus LAN in Philly and
then to our CIS complex and then to a big sparc.


FTP connections yield a delivered data rate to the host of 14.5 kilobytes
per second in either direction


Not bad at all.
