Hi,

The current implementation of Neutron L3 agent allows us to scale
virtual routers on multiple agents but does not provide High
Availability on :
- namespaces, virtual interfaces (both in north and south)
- established connections between external & internal network.

The idea here is to start a discussion about a new design that we could
implement in the next release.
Since there exists some conversations on this topic, I want to share my
ideas with a public document we wrote [1] with my team.

Table of contents:
- Abstract about current implementation
- Current Architecture
- Proposal #1: Health-check (which is not my final solution, but just an
existing way).
- Proposal #2: VRRP + conntrackd (new backends for improving L3 agent)
- Design session proposal for next Summit


Feel free to bring your thoughts.
After the discussion, maybe could we write new blueprints.

Note: the document is public and you are allowed to comment. If you need
more access, I can of course grant you write rights.
