Overview of IPTV Service Applications

IPTV and multimedia service sessions are typically established in multiple phases that require changes to installed policies and authorized bandwidth while the service session remains active. To support IPTV sessions, the SAE allows changes to active service sessions. These changes include:

You can integrate IP servers into an SRC-managed network so that the SRC software can receive network resource requests from IPTV applications to perform admission control and install policies. The SRC software can also set up and manage the initial label-switched paths (LSPs) between the video servers and the edge routers.

When the SAE activates a service session, it authorizes the session with authorization plug-ins; it may use the SRC Admission Control Plug-in (SRC-ACP) application to perform call admission control (CAC) and allocate bandwidth; and it installs the policy required for the service on a router interface.

To support IPTV services, we provide a sample IPTV application that uses the extended capabilities of SRC-ACP and the SAE. You can use SRC-ACP to initialize and execute applications that are attached to congestion points. You can use the SAE router driver to set up and manage LSPs.
