Hi,

I am building the router based on linux kernel.

The hardware details are below,
2 - 64 bit quad core processor (3Ghz core).
RAM- ?24GB RAM.
PCI express slot- connected with Quad Port 100Mbps Ethernet adapter -2. (so total 8 ethernet interfaces)


I just want to calculate the maximum traffic the ?router can handle..?.

The maximum traffic could be, also 8 ?ports(100Mbps) * 2 directions = 1600Mbps.

Can this system(kernel + hardware) handle this much traffic. (Assume the best case)?

Yes, it can. I have seen a benchmark which basically said that a single quad
core cpu with ~3GHz was enough for about 4 links with 10 *gigabit* each.

What is the packet size ?

It was ~10 million packets per second with 500 bytes packet size, if I
remember correctly. The speed is highly depending on packet size. Actually
packets per second is actually a better unit than (k/m/g)bits per second. I
mostly care about the 500 bytes packet size values in benchmarks because
this is what I think is a good approximate for the average size in most
networks. However, the 64 byte packet size values might also be interesting
when dealing with "weird" applications or DoS attacks.
