"""Hold aggregate metadata for a collection of networks.
|
|
|
|
This object holds aggregate information for a collection of neutron
|
|
networks. There are two types of network collections we care about and use
|
|
this for: the collection of networks configured or requested for a guest
|
|
and the collection of networks available to a host. We want this
|
|
information to allow us to map a given neutron network to the logical NICs
|
|
it does or will use (or, rather, to identify the NUMA affinity of those
|
|
NICs and therefore the networks). Given that there are potentially tens of
|
|
thousands of neutron networks accessible from a given host and tens or
|
|
hundreds of networks configured for an instance, we need a way to group
|
|
networks by some common attribute that would identify the logical NIC it
|
|
would use. For L2 networks, this is the physnet attribute (e.g.
|
|
``provider:physical_network=provider1``), which is an arbitrary string used
|
|
to distinguish between multiple physical (in the sense of physical wiring)
|
|
networks. For L3 (tunneled) networks, this is merely the fact that they are
|
|
L3 networks (e.g. ``provider:network_type=vxlan``) because, in neutron,
|
|
*all* L3 networks must use the same logical NIC.
