Feedback form is now closed.
This talk will seek the method to build VM networking infrastructure through eBPF. Traditional networking datapath and several limitations of it will be reviewed first . Then eBPF based method will be introduced: eBPF based filtering allows a user configurable high speed packet filtering solution like virtio-net filter for vhost; eBPF based packet steering allows userspace to inject its own steering policy like RSS; eBPF/XDP based host datapth acceleration allow userspace to build a flexible and efficient datapath on host; eBPF offloading allow guest to offload eBPF tasks like XDP and tc_cls to host for a native packet processing on host. At the end, the performance numbers, challenges and future work will be also discussed.
