I am requesting some help from those with networking experience with bridges. Our current engineering network is growing rapidly (400 plus nodes) and we feel it is time to isolate some of the traffic. We think that bridges will help solve some of the high traffic problems we are seeing which we think leads to large delays and constant jams. We also have two networks which we need to bridge together. One is a secure network(has been isolated physically from the engineering network and supports the XNS proto
col family) and the other is the tcp/ip engineering network previously mentioned.
Question 1 - What name brand bridges should we consider for dividing the tcp/ip network up into smaller segments? Our current engineering network runs steady at around 20% of the bandwidth with peaks of 60% with no bridges. Packet rates average around 1000 packets/sec but do go higher at peak times.
Question 2 - What bridge would be recommended for the secure net to engineering net problem. The secure net does not have a great deal of traffic but it most important to restrict access into the secure network. Does the fact that the sec ure network runs the XNS protocol suite and the engineering network runs a combination of tcp/ip and XNS make a difference?
Any suggestions or help based on your own experience will be greatly appreciated
We have installed a Retix model 2200 to help in one area ofthe engineering network as of yesterday. Is this a good start? Has anyone had experience with this product?
Thanks in advance......... Charlie Dobbins (cdobbins@Columbia.NCR.COM)
