Does routing on Linux have any hardware acceleration for IP packets?
- pak9rabid 7mo agoYes. You can take advantage of Netfilter's flowtable infrastructure and if you have the right hardware (NVIDIA/Mellanox ConnectX-5 or MediaTekMT7621) it will actually offload the processing of these packets to the NIC hardware. This only applies to established connections, however, but that typically accounts for like 95% of the traffic passing through.
- brcmthrowaway 7mo agoAwesome. I wonder if packet processing can be GPU accelerated
- pak9rabid 7mo agoIt looks like it can. Check out GPUDirect RDMA.
