Session Border Controller: First To Third Generation
The Session Border Controller was invented almost a decade ago. It has witnessed many major changes
in its offered functionality and features. If we say specifically, then there are 3 generations of SBC
solutions based on the major changes made in it.
The very first generation of the Session Border Controller were mostly a hardware based solution
which used to get installed on the border of the network and control the call traffic in it. It had been
used for the PSTN (Public Switched Telephonic Network) initially. In a simple language, it was
working like a simple firewall. This system was adding the hefty cost to the security budget of the
organizations. Moreover, the SBC solutions of the first generation were only performing NAT traversal
and topology hiding to make the network secure.
The second generation of Session border controller solutions were software. It made it more popular
because of the ease of use involved. Moreover, the SBC solutions of these generations were not only a
software which filter the traffic coming and going out of the network border, but also offered additional
features. It was performing this job and also had additional features such as media transcoding, support
for more complex flow of calls, etc. Moreover, it was also capable of handling the video calls. The
second generation Session Border Controller solution was offered advanced security features along
with the NAT traversal and topology hiding. These features include:
Denial of Service Attack prevention
IPSEC Support and monitoring
And many more
Currently, there is a third generation of Session Border Controller solution in use. It has advanced
mechanism of security. Along with the security, it also offers additional features such as QoS.
Moreover, today's SBC solution comes as a virtual solution which can be installed on client's server or
