CRUD |
Create, read, update, and
delete (CRUD) are the basic functions of
persistent storage in computer
programming. |
entity |
Any piece of hardware or
software that can connect to the network
services provided by OpenStack Networking.
An entity can use OpenStack Networking
services by implementing a VIF. |
IPAM |
Internet Protocol Address
Management (IPAM) is a means of planning,
tracking, and managing the Internet
Protocol (IP) address space that is used
in a network. |
layer-2 network |
A virtual Ethernet network
that is managed by the OpenStack
Networking service. Currently, OpenStack
Networking manages only Ethernet networks.
|
network |
An isolated virtual layer-2
broadcast domain that is typically
reserved for the tenant who created it
unless the network is configured to be
shared. Tenants can create multiple
networks until they reach the thresholds
specified by per-tenant quotas. |
plug-in |
A software component that
implements Networking API v2.0. |
port |
A virtual switch port on a
logical network switch. Virtual instances
attach their interfaces into ports. The
logical port also defines the MAC address
and the IP addresses to be assigned to the
interfaces plugged into them. When IP
addresses are associated to a port, this
also implies the port is associated with a
subnet, as the IP address was taken from
the allocation pool for a specific subnet.
|
subnet |
An IP address block that can
be used to assign IP addresses to virtual
instances. Each subnet must have a CIDR
and must be associated with a network. IPs
can be either selected from the whole
subnet CIDR or from allocation pools that
can be specified by the user. |
VM |
A virtual machine (VM) is a
completely isolated guest operating system
installation within a normal host
operating system. |
