What is a Session Boarder Controler?
A Session Boarder Control (SBC) allows for peering between IP networks allowing customer traffic to pass through many different parts of a network in order to connect to its final destination. SBCs help at the network border connections (where one network “meets” another) to manage the sessions for security and quality control, translate protocols (SIP, MGCP, SCCP, IAX) and provide seamless service connections.
VoIP Service Sector Growth Fueling the Need For Session Boarder Controlers
According to a recent Frost & Sullivan report, World Session Border Controller Markets, the Session Boarder Control had market revenues of $123 million in 2006 and estimates this to reach $163 million in 2013, after first peaking at $220 million in 2009. This is huge growth for a sector of the VoIP hardware market that is extremely important to service provider performance, yet never really publicized.
