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. -Michi -- programing a layer 3+4 network protocol for mesh networks see http://michaelblizek.twilightparadox.com
