#define KP_DEFAULT_PER_CPU_STICKY_BUCKETS 1 << 10

kp-plugin implements a MagLev-like load balancer.

http://research.google.com/pubs/pub44824.html

It hasn't been tested for interoperability with the original MagLev but intends to provide similar functionality. The kube-proxy receives traffic destined to VIP (Virtual IP) addresses from one or multiple(ECMP) routers. The kube-proxy tunnels the traffic toward many application servers ensuring session stickyness (i.e. that a single sessions is tunneled towards a single application server).
