[openstack-dev] [neutron]Should segments become a default service plugin?

2016-08-31 Thread Hong Hui Xiao
Hi all. Before routed network, functions in [1] are used to manage network segment. Routed network introduces a plugin [2] to manage network segment. So, now there are 2 code paths to do the same job. Except in ml2, the segments plugin will be used to manage network segments. Patch [3] [4] will

Hi all. I was working on this bug [1] (ML2 doesn't return fixed_ips on a port update with binding) I think it should be a DB issue, and I put some investigation result at [2]. I even made up some code change [3] to resolve the bug. But, I don't know the actual root cause for the problem. And w

I update [1] to auto delete dhcp port if there is no other ports. But after the dhcp port is deleted, the dhcp service is not usable. I can resume the dhcp service by adding another subnet, but I don't think it is a good way. Do we need to consider bind dhcp port to another segment when deletin

We need to provide the integration between the service plugin that provides the segments endpoint with ML2 to

Hi all. I did some investigation recently. And I think we can start some discussion now. All below thinking is based on the current implementation of neutron. With routed network, a subnet will be considered as a L2 domain. Things might change. I think routed network in OVN can implement in this

Hi, Can we just add "availability_zones" as one Column in Network? And update it when "NetworkDhcpAgentBinding" updates. The code will be a bit more complex, but it can save the time when retrieving Network resource. From: Hirofumi Ichihara To: "OpenStack Development Mailing L
