The Concept of Session Border Controllers

Posted by PARTIK on December 29th, 2015

In the past developers tried to resolve the issues in IP communications using the VoIP system. However it soon became evident that the VoIP calls would have problems moving through the firewalls. It also got problems in moving to different networks like the SIP as well as the H.323. To address these problems the concept of session border controllers was developed. This also made the security and management easier with access control systems.

IMS Compliant Session Border Controller

A recent development in the field is that of IMS compliant as well as decomposed border controllers that would work giving a FMC solution providing service optimization and total security. With regulatory compliances the app also optimizes revenue and profit protections in respect of IP interactive communications. Thus the controllers can now be used as decomposed solution with software configurations accordingly.

SBC Software Configuration

SBC in its decomposed format will have separate session control and border gateway and similarly separate signaling as well as media control systems for the SIP sessions. They also are compatible to different hardware platforms such as the Net-Net 4000 as well as the 9000 series platforms. In result the control system is able to deliver interconnect border control function of I-BCF conveniently. Other functions that are enabled due to such software configuration are core gateway border functions and also the service based policy decision functions.

Importance of SBC

SBC is considered to be one of the most important elements in networking process including the IP PBX system. Today many large companies and establishments in private and public sectors are turning their heads towards SBC for setting up effective IP PBX in their organizations. Accordingly many SBC vendors are also appearing on the scenario and they are offering products as well services for their clients.

SBC Packages from Vendors

Many clients prefer to have packages instead of going for the individual SBC from the vendors. Catering to such demands and requirements of the buyers the vendors are also coming up with different packages including the VoIP, IMS services as well as the fixed mobile convergences or FMC in one package based on border control functionalities. The process makes the implementation of technologies involved easier and convenient for the end users. On their part these applications rely largely on SBC functionalities for their performances.

SBC Technology as Complementary

Some of the major companies are now considering SBC as complementary to their existing product lines. They are also focusing largely on the PSTN-VoIP network connectivity. That is why one can see large numbers of VoIP islands on both operator as well as the enterprise sides.

Not the Easiest of Tasks to Accomplish

However the connectivity is not one of the simplest of the tasks to accomplish. There is necessity of something that would guarantee traversal of the signals through networks and also the firewalls. Up to the 7th layer the networks may not use the same protocol for signaling.
