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.

Upstream Trello: https://trello.com/c/DMLsrLfq/9-snat-decentralized-ovs-nat-based NetVirt spec: https://git.opendaylight.org/gerrit/#/c/49029/ 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). It fails on HA setup https://bugzilla.redhat.com/show_bug.cgi?id=1505835 Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA. For information on the advisory, and where to find the updated files, follow the link below. If the solution does not work for you, open a new bug report. https://access.redhat.com/errata/RHEA-2017:3462 |
