The Growing Importance of Session Border Controllers!

When Session Border Controllers or SBCs were first launched in the late 90’s their function was simple – become the equivalent of a firewall for voice over IP (VoIP) services.   A critical element of deploying VoIP networks, the SBC ensured that networks were secured against fraud and malicious attacks.  But during this same period of time, something else was taking place in the rollout of SIP-based (Session Initiation Protocol) VoIP networks.  Competing VoIP equipment vendors were taking advantage of the flexibility afforded by SIP technology and extending it to create differentiated products in non-consistent ways.   The result was a series of VoIP “islands” that worked well within their own, single-vendor environments, but could not deliver the same set of services across their borders into different environments.  It was up to the SBC to provide the interworking, protocol conversion, IP Interconnect, IP Exchange (IPX), repairs and normalization points between these disparate networks.  SBCs have now become a very critical component of the IP communications network.  According to Infonetics Research, the SBC market is expected to grow from $310 million in 2011 to $775 million in 2016.

In a recent white paper GENBAND examined the opportunities and challenges facing today’s communications companies -- and how a new generation of session border control technology is allowing them to exploit these opportunities and address these challenges.  Read the whitepaper here
