Hi Tom, Well that's where I disagree. And where I am looking for clarification. We were NOT using systems with Buses limited to 32bit/33Mhz or Basic PCI. The routers that we used for testing were using the Intel 7501 chipset, spec'd at allowing 3GB of throughput, and PCI-X Bus. There are

1GB Fiber is typically using Packet over SONET. I have typically seen over 500 mbps on these links, even from Telcove/L3. But the distance is usually a factor. Running from NoLa to ATL on a long-haul, single hop 1GB fiber run introduces lots of regen issues, so 500 mbps would be a blessing.

Jeff, The solution is simply a hardware upgrade for starters. A 32-bit/33 MHz bus will top out around 200 Mbps. If you look for a bus with higher speed slots, you can triple your throughput without adjusting ANYTHING in your Linux kernel. Well thats where I disagree. And where I am looking

Gigabit Ethernet, can pass 1 gbps when it uses greater than a 9600 MTU frame. But with a 1500MTU frame, it can barely pass 200 mbps. The problem is that most Internet and subscriber traffic is using a 1500MTU or smaller frame. So in theory, its would be just as efficient and fast to bond two

Tom, How are the big boys doing it? Surely ATT and others are transporting more than 200Mbps across their 1GB fiber links. Travis Microserv Tom DeReggi wrote: Gigabit Ethernet, can pass 1 gbps when it uses greater than a 9600 MTU frame. But with a 1500MTU frame, it can barely pass 200
