What is the full form of SBC?

Answer: A session border controller is the full form of SBC. Some features of SBC are:

1. SIP-based voice over Internet Protocol (VoIP) networks are protected by the SBC, which is a network component.
2. In a peering scenario, SBCs were originally deployed at the intersections of two service provider networks. A Session Border Controller (SBC) is a network function that secures voice over IP (VoIP) infrastructures while allowing incompatible signalling communications and media flows (sessions) from end devices or server software to communicate with each other. Enterprise infrastructures or any carrier network supplying commercial home, business, fixed-line, or mobile VoIP services use SBCs. They are commonly installed at the network edge as well as at carrier interconnects, which serve as segmentation points (borders) between customers and other service providers.
3. By acting as a back-to-back user agent, an SBC protects a core SIP network and cloud infrastructure while also providing client/server interworking (B2BUA). It does so by essentially terminating and re-establishing each session, operating as both a user agent server (UAS) and a user agent client (UAC) at the same time. By acting as a back-to-back user agent, an SBC encrypts a core SIP connection and application servers while also providing client/server interworking (B2BUA). An SBC can granularly regulate a communications session by effectively terminating and re-establishing each session, functioning as both a user agent server (UAS) or user agent client (UAC) for every signalling message on each call leg.
4. To counter DDOS assaults, SBCs use thorough entrance Access Control Lists (ACLs) and rate restrictions, as well as analyse each communication to prevent distorted packet exploits. Complex rules can be applied to message elements and enable interworking by parsing each SIP header and payload, such as the Session Description Protocol (SDP). While Session Border Controllers were once only available as specialised hardware appliances, they are now available as pure software components running on x86 commercial off the shelf (COTS) server platforms.
