I am working on a network comprised of approx 25 subnets seperated by cisco routers. several routers have bridging options set for LAT and XNS protocols. Each subnet has a mixed bag of equipment ie. suns, vaxes, hp`s, pc's, etc.... Typical utilization on the subnets which have a majority of VAX / PCs are in the 3 to 5 percent range.. The PC's are running novell The Vaxes are running Decnet Phase IV and TCP/IP. On the subnets with a majority of Sun workstations: We are seeing average utilizations of 30 to 40 % during working hours and 25 to 30 percent during off hours. Depending on who you talk to this is normal or very high... I would like to hear from people who have a large number of suns on their network to find out what they believe is a normal range for baseband ethernet utilization.... I am using a Network General sniffer to watch average network utilization . I capture all protocols and all mac (ethernet) addresses. We have no diskless nodes on the subnets. Each subnet has its own server. There are approx 25 suns on each subnet which are also mixed between 3/60s, 4/60s, and 4/280 as servers. The network is used by engineering groups who require access to files on other subnets . There is considerable hard and soft mounting between the different subnets. The reason I bring this up is that I am having trouble with 10BaseT equipment being linked by fiber lines. The 10BaseT equipment doesn't see or recognize collisions and due to the high utilization collisions are inherant to OUR / ANY network..... /-----------------------------------------------------------------------------/ / Success is staying one step ahead of OBSOLESCENSE / / / / INTERNET: fpb@mlb.semi.harris.com / / Forrest P.
