Session Border Controllers

Session Border Controllers (SBC) are devices or applications that are used to control real-time session traffic at the signaling, call control, and packet layers as they cross borders between IP networks or between network segments. They admit sessions and, where necessary, reject sessions in order to protect the network from 'denial of service' (DoS) attacks and sudden spikes in congestion. A session is any real-time voice, video, presence, instant messaging or multimedia collaboration session using IP session-layer signaling protocols, such as SIP or H.323. In addition, SBCs may also be used to perform a range of call-control functions that help to reduce the load on other devices within the IP environment, these might include; Quality of Service (QoS) functions, policy-based routing and signaling protocol interworking.

SBC monitoring provides System Administrators easy access to see the status of each SBC device in the environment together with details of the real-time session traffic that is being processed. At present the following SBC vendor devices are supported:

  • Oracle SBCs

  • Avaya Session Border Controller for Enterprise

  • Cisco Unified Border Element (CUBE) SBCs

  • Ribbon devices

  • AudioCodes Mediant SBC models.
