Hi:

In current DVR design, SNAT is north/south direction, but packets have
to go west/east through the network node. If every compute node is
assigned a public ip, is it technically able to improve SNAT packets
w/o going through the network node ?

SNAT versus floating ips, can save tons of public ips, in trade of
introducing a single failure point, and limiting the bandwidth of the
network node. If the SNAT performance problem can be solved, I'll
encourage people to use SNAT over floating ips. unless the VM is
serving a public service
