[comp.dcom.telecom] Real Useability of Applications over Slower Communications

dap@compsci.aberystwyth.ac.uk (Dave Price) (03/04/90)

I am interested in gathering experiences/references of people's
reactions of the useability of applications over slower networks. In
particular I wish to consider the types of applications we all happily
use over fast LANs, but running over (say) 4800 bits/sec through 64 K
bits/sec upto a couple of megabits/sec.

For instance, we know we can use file access protocols,(e.g. Sun NFS)
over SLIP. What data is available though concerning how really useable
it is ??  For instance, a compiler on a PC might pick up its source
files over a 9600 line.  The compiler only reads source for a small
proportion of its execution and so that might give very acceptable
performance.

I am really trying to think forward(?) to the emerging ISDN facilities
that are becoming available. What will really make sense on 64
Kbits/sec lines ??

I am trying to collect data myself. I am running some applications
over varying speed SLIP lines and recording the results. I am
considering coding a 'packet driver' that will run between two MITEL
ISDN cards that I have (I also have student projects designing and
building cards, simple exchange, terminal adaptors etc).

Anyway, all input that people have will be very gratefully
received....

Thanks Folks,

	Dave Price
