Weave – The Docker Network
I hope all of these Docker overlay networks start using the in-kernel overlay network technologies soon. User-space promiscuous capture is obscenely slow.Take a look at GRE and/or VXLAN and the kernels multiple routing table support. (This is precisely why network namespaces are so badass btw). Feel free to ping me if you are working on one of these and want some pointers on how to go about integrating more deeply with the kernel.It's worth mentioning these protocols also have reasonable hardware offload support, unlike custom protocols implemented on UDP/TCP.
