I am converting a network of approx 300 PCs and MACs from an XNS based NOS to
TCP/IP, on ethernet (the NOS is Net/One PC). I would like to assess what
impact the conversion will have on network traffic. I believe that the major
impact on the network will be from differences in broadcast packet patterns.
If you are running a similarly sized network with file sharing and TCP/IP,
please see if you can easily furnish me with the following:
. brief description of typical applications, number and types of
nodes on the network
. % of network utilization
. what percent of what's utilized is due to broadcast packets
. what applications are most significantly responsible for the
broadcasts (i.e. dynamic routing, RARP, SNMP...)
Here's some more information about why I'm doing this (for those who are
interested):
Currently, this network is completely bridged, but uses bridges that can be
programmed with XNS "network" numbers to isolate broadcasts (I'm not an XNS
expert, so forgive if I have stated this with incorrect terminology). There are
4 of these "subnets". Once the conversion to TCP/IP is done, the bridges will
pass all broadcasts throughout the network. My assessment is being done to aid
in making a decision about going to a subnetted network with routers as part of
the conversion, as opposed to moving to subnetting in approx 1 year.
Thanks for any measurements or empirical descriptions you can offer,
Heather Burris
