Kube-proxy, as the load balancer for k8s, is one of the most important components for container networking.

The kernel mode(ipvs, iptables) implementation is flexible but with poor performance.
This presentation will introduce a pure userspace implementation by using DPDK + Layer4 load-balancer, which shows high performance and keeps flexibility.

It includes below key elements:
1) Implement a k8s service proxy, including load balancer, including FNAT, DNAT
2) Different schedule algorithm like RR, WLC, WRR, etc.
3) SNAT mode for Internet access from the internal network.
4) User-space Lite IP stack (IPv4, Routing, ARP, ICMP ...)
5) Integration of K8s and DPVS(dpdk-lvs).
