3.6.1 About the application manager
The Application Manager supports default and add-on network services, and enables installing,
upgrading, enabling (starting), disabling (stopping), and uninstalling SDN applications.
Application manager and controller teams
When controllers are operating in a team, actions performed on one controller are propagated
to the other controllers in the team. Actions you select in the Applications window for one controller,
such as Install, Enable, and Disable, are propagated to the other controllers.
Embedded applications
The following applications are embedded in the controller and are installed when you install the
controller:
• Link Manager
• Node Manager
• Path Daemon
• Path Diagnostics
• Topology Manager
• Topology Viewer
For more information about the embedded applications, see “Understanding the embedded
applications” (page 10).
Prerequisites for installing an application
Any application to be installed on the controller must meet the following requirements:
• It must be in a zip format.
• The zip file must be on the same system as the controller.
• It must contain an application descriptor file containing key value pairs of the attributes
associated with the application, including all mandatory attributes.
Applications you purchase from HP or the HP SDN App Store meet these requirements.
For information about developing applications that meet these requirements, see the HP VAN SDN
Controller Programming Guide.
