SBC (Session Border Controller)

SBC (Session Border Controller)

SBC connects any IP phone to any next-generation Internet-based network. SBC provides an excellent interface point between enterprise premises and large area networks. It also includes integrated E-SBC functions to accommodate signaling adaptations. Two Ethernet interfaces provide a physical connection between LAN and WLAN.

What does Session Border Controller refer to?

To understand what an SBC is and does, it's best to break the terminology down into simple terms.

A"session" Communication between two people, usually a telephone call. Two streams make up each call. The first stream is composed of one or more signaling messages exchanges that control the call. One or more call media streams carry audio, video, and data during the call. They also provide statistics and information about the exchange. These streams together make up a session. Each call session is supported by the SBC, which controls and monitors its data flows.

A"Border" is The boundary that separates one network from the other. This border allows data, calls, and other media to flow through the internet into a network while maintaining security and filtering regulations. The SBC is responsible for managing data flows across borders.

Finally, "Controller" is the section of the SBC that influences and controls data streams and sessions as they travel over borders and between parts of a network. The SBC regulates and controls all communication via the internet or any connection to your network.

What are the advantages of an SBC to businesses?

Security

Session Border Controls are used in businesses for security reasons. SBC protects against hackers, cyber-attacks, and any other bad influence from outside of the network. The SBC is essentially more efficient and secure. An SBC is designed to protect your network and replace the firewall used for general systems and networks. The SBC encrypts signaling, data, and media to prevent outside interference from monitoring your activity and information.

SIP communications

SBCs enable different components of a network to communicate with one another and share data. An SBC's primary role is to facilitate SIP communication between devices, systems, and gateways that use or speak differently. The SBC modifies or normalizes SIP signaling and messaging to ensure that everything is correctly communicated.

Service quality

The SBC implements the Quality of Service or QoS policy that measures the performance of a service or network. The SBC regulates the flow of data into and out of the network and prioritizes traffic control, rate policing, and call admission control.

Media Services

The SBC's latest version regulates real-time communications, especially media services. This includes support for voice and video calls, data interworking, and media transcoding. The SBC converts between codecs through media transcoding. Codecs are used to convert video and voice signals into digital transmission. Transcoding can be used to translate the signals into digital transmission. This results in higher sound quality and reduced network bandwidth. This results in better calls for clients and colleagues.

Key Benefits of SBC

Session Border Controller Solution (SBC) supports QoS (quality of service) and Scalable Solutions which benefits the VoIP network of the businesses. The SBC usually implements the QoS policy for a network and prioritizes flows. This can include traffic policing and resource allocation as well as rate-limiting and call admission control.
