What is the ClearFog's acheiveable net badwidth?

Hi,
I wanted to know how much BW was acheiveble if I were to use a ClearFog LX2160A as a network equipment changing just the IP header (actually it would be a IPv4<–>IPv6 transform) ?

I have reached out to the developer that has been optimizing this for another product. He should be able to give you a ballpark figure.

Well if you have the exact figure it will be useful one day no doubt. For the application I have in mind, just knowing that the throughptu can be over 100Gbps would be great news. Ideally if you tell me it can reach 120Gbps or beyond I’d probably order 2 of these within a day I get the news :slight_smile:
An article on Fedora Magazine said the IP Accelerator could handle 160Gbps in theory so I’m optimistic.

Hi,
We reached wire speed on the 100Gbit port using DPDK (with a Mellanox NIC), with ~1500B packets.
Reaching 120Gbps is not possible, since this is a 100Gbit port.
You could use the additional 4 10G ports to reach more than 100Gbps (the performance with this setup hasn’t been tested).

All the figures refer to simple transmission of packets, no changes in the IP headers.

Indeed I was thinking of 100Gbps + 2 10Gpbs ports of course.
I’ll try changing the headers as needed and setup a testbench on the board I have (4x10Gbps only). And if the CPU remains low enough I’ll move on. Thanks :slight_smile:
