Speed limitations and NIC compatibility
2 posts · Closed
Hello,
What are the speed limitations of this Connection Emulator (if any)? Will it work correctly with a dual (bridged) 10G NIC? What about 25G or 40G dual port NICs, and 2.5G/5G too?
Primarily, I am looking for a solution to emulate additional latency due to distance in the path of two switches, and would want to do this now using 10G (and perhaps 1G if only a single device under test) for a one-off consultancy project. But future needs might include 25G or 40/50G, maybe way off yet, but I would like to understand anyway. I know some of these higher speeds may seem excessive now.
Many thanks.
In general, our software can't handle more than 1 Gbps due to the implementation of packet processing in user mode. I am not aware of any tools that support latency emulation at such high speeds. It would require some highly specialised purpose-built hardware, so it is unlikely that there is any software in existence that can do it.
