Hello. I am looking for suggestions on how to improve/increase the the capibility of my wide area network and distributed applications. Here is what my current setup looks like: Sun Workstations running 4.0.1 | | | | | +---+ +---+ | |--| X |============================| Y |------| | +---+ 6.0A MCP/IR link +---+ | | | | | | +---+ | | | Z |------| | +---+ | | | | | ethernet A ethernet B The internet link is limited to 32 to 128 kbps. There are actually a pair of MUX's (that I haven't drawn) in this link also. I have two classes of applications that exchange data between the A and B ethernets: 1) applications with large data transfers that swamp the link's bandwidth 2) interactive applications that send small bursts of data. My problem is: when the link speed is low, the class 1 applications ruin the interactive nature of the class 2 applications. The MCP board will support up to 4 loadsharing sunchannels, but how can I link an application with a specific subchannel. I don't think this one is possible, but I might be missing something obvious. What about connecting one point-to-point link to Y and a second point-to-point link to Z? Will this work at all? Will packets destined for B.Y and B.Z be routed on the different links? If this works, I could run all class 1 applications on Y and class 2 applications on Z. Are their any other approaches? Any suggestions would be appreciated. Basically what I want is to be able to assign priorities to the IP packets. Linn -- Linn Hower lh1@INEL.GOV Phone: 208-526-9353 at the Idaho National Engineering Laboratory, Idaho Falls, ID
