Doc Text:
The new conntrack-based SNAT implementation, enabled by default, uses the Linux netfilter framework to do the NAPT (Network Address Port Translation) and track the connection. The first packet in a traffic is passed to the netfilter to be translated with the external IP. The following packets will use the netfilter for further inbound and outbound translation. In the netfilter, the Router ID will be used as the Zone ID. Each zone tracks the connection in its own table. The rest of the implementation remains the same. The conntrack mode also enables the new High Availability logic that newly considers the weight associated with each switch. Also, the switch will always keep one designated NAPT port open, which improves the performance.

Description Nir Yechiel 2017-01-18 08:36:49 EST 
Description of problem:

In Source Network Address Translation (SNAT), the NAT router modifies the IP address of the sender in IP packets. SNAT is commonly used to enable VMs with private addresses to communicate with servers on the public Internet, when floating IPs (1:1 NAT) are not used.
Comment 2 Nir Yechiel 2017-01-18 09:11:46 EST 
Assuming we go with a conntrack-based solution (which is currently being developed for Crabon) - we need to pay attention for differences between OVS and OVS-DPDK (as the first uses the kernel based conttrack implementation, and second the DPDK/user-space one).
