Video-Conferencing Support

The Oracle® Enterprise Session Border Controller (ESBC) supports H323 video-conferencing environments using the H239 Procotol for video-conferencing. The ESBC provides critical control functions to enable high quality interactive communication—voice, video and multimedia sessions—across IP network borders.

For additional information about the H323 Protocol, see the ACLI Configuration GuideACLI Configuration Guide.

The ESBC architecture supports both voice and video applications. It uses Codec Media Profiles to determine the proper amount of bandwidth allocated for a given session, distinguishing between G.711 or G729 voice and H.263/264 video requirements. By supporting video transmission as well as voice over the IP Multi-protocol label switching (MPLS) core, the ESBC allows you to roll out new services to your enterprise customers such as video/audio conferencing.

Note:

IP MPLS is a packet-switched network that uses the Internet Protocol (TCP/IP) enhanced with the Multi-protocol label switching (MPLS) standard.

The ESBC allows for aggregate bandwidth policies to be configured for each realm. As the ESBC processes call requests to and from a particular realm, the bandwidth consumed for the call is decremented from the bandwidth pool for that realm. The ESBC determines the required bandwidth from the SDP/H.245 information. Any request that would cause the bandwidth constraint to be exceeded is rejected with a SIP “503 Service Unavailable” or an H.323 Release Complete.

To alleviate the bandwidth demands of high-definition video streams, the ESBC offers a 2 or 4 Gigabit PHY card option.
