OpenStack Networking
|
|
====================
|
|
|
|
OpenStack Networking (neutron) allows you to create and attach interface
|
|
devices managed by other OpenStack services to networks. Plug-ins can be
|
|
implemented to accommodate different networking equipment and software,
|
|
providing flexibility to OpenStack architecture and deployment.
|
|
|
|
It includes the following components:
|
|
|
|
neutron-server
|
|
Accepts and routes API requests to the appropriate OpenStack
|
|
Networking plug-in for action.
|
|
|
|
OpenStack Networking plug-ins and agents
|
|
Plugs and unplugs ports, creates networks or subnets, and provides
|
|
IP addressing. These plug-ins and agents differ depending on the
|
|
vendor and technologies used in the particular cloud. OpenStack
|
|
Networking ships with plug-ins and agents for Cisco virtual and
|
|
physical switches, NEC OpenFlow products, Open vSwitch, Linux
|
|
bridging, and the VMware NSX product.
|
|
|
|
The common agents are L3 (layer 3), DHCP (dynamic host IP
|
|
addressing), and a plug-in agent.
|
|
|
|
Messaging queue
|
|
Used by most OpenStack Networking installations to route information
|
|
between the neutron-server and various agents. Also acts as a database
|
|
to store networking state for particular plug-ins.
|
|
|
|
OpenStack Networking mainly interacts with OpenStack Compute to provide
|
|
networks and connectivity for its instances.
