to date, all Ethernet LAN's at this location have been modest: 2 or 3 systems
connected for some development project. we're about to connect these up
to make a 15 node network. several folk (don't laugh, now) are scared this
will already be saturation. they're comparing it to a disk drive with a
10 Mbits/sec bandwidth and how many users it will support. i've argued (from
gut feel) that the traffic patterns are totally different.
what i haven't said yet in these arguments is that 10 Mbits/sec is never
really reached in an Ethernet LAN. real throughput seems to flatten out
out a much lower rate, like 3 or 4 Mbits/sec (my recall on what i've read
is a big foggy). if i say that, it'll really frighten 'em.
could someone with genuine experience with TCP/IP or XNS LAN's tell me what
the practical number of nodes is on a LAN in an engineering organization?
also, can anyone point to papers/studies which discuss the experienced
throughput limitations of Ethernet? thanks!
