Network service type
Every time you add a physical machine, you must choose its rack and specify the network service type (NST) its network interfaces are connected to.

There are three different kind of networks:
Private: Bound to the virtual datacenter (VDC) they were created in.
The VLAN network tag is taken from the VLAN network tag pool of a rack automatically, bounding the network workload to it.External: Bound to a datacenter and a cloud tenant (enterprise).
This means that the network VLAN tag has the same meaning for all racks in the datacenter.Public: Bound to a datacenter only.
They are similar to external networks, but more than one enterprise may use them.
Private networks are bound to the rack they were defined in, and their VLAN network tags have no meaning outside this rack. This means that VDCs are bound to the rack their private networks are defined in.
External and public networks can be used in all racks in a datacenter. Their VLAN network tags must be defined in the infrastructure before you define them inside Abiquo.
