One possible solution would be to buy SmartBits test set ($17000 for the box with 20 slots, $1500 each 10BT card, $4000 - S/W). Another solution could be to use 2 FreeBSD PCs w/4..5 Ethernet cards, depending on the number of free (PCI) slots. Suppose we could group the cards as following: PC1 PC2 +----+ +----+ | E1 |-subnet1-| E1 | | E2 |-subnet2-| E2 | | E3 |-subnet3-| E3 | | E4 |-subnet4-| E4 | +----+ +----+ Now we would connect: subnet1 - bridge1 - subnet2 subnet3 - bridge2 - subnet4 The obvious problem is to force FreeBSD to send packets through the interface cards even though both sender and receiver cards are located on the same PC. My questions are: 1. Is it possible? (I'm really very new to this field) 2. Can it be done easily (I'd prefer not to hack the kernel). 3. Did anyone hear of a similar application (in other words can I steal the code:) 4. What S/W can I use to obtain performance statistics (lost packets, throughput etc). Any help is greatly appreciated, Thanks, -Edward PS. They have standardized here on Intel EtherExpress 10/100. Will Pentium 200 w/32 Mb RAM handle 4/5 of these?
