The S60 also has 1.25GB of deep packet buffering
"The fix for congestion is not necessarily to move to 10 Gigabit switches, according to Force10, but rather to push line rates in a Gigabit switch and give the device ultra-deep buffering to cope with those momentary rogue waves on the network."
"The S60 also has 1.25GB of deep packet buffering"
I'm assuming this means gigabytes, as written, and not gigabits.
Can someone explain why such large buffers are needed? My previous understanding was that excessively large buffers in routers could be detrimental because it doesn't do anything to actually increase the transmitting speed, but will accumulate a large backlog of packets that ultimately causes significant latency.
Consider a 1gbps generator and a 100mbps consumer, what's the net benefit of keeping an enormous buffer in the middle?
Sliding window TCP implementations would ensure the buffer remains full (since the packets are not being dropped) which happens to be the worst case for latency.
I'll admit this is not my domain, so anyone who knows better feel free to let me know.
