Definitions

• This invention pertains to a system and method for session border gateway functions using distributed virtualized computing and communications resources.
• a session border gateway can be logically split into two entities, namely a signaling path function and a data path function. This split provides clarity when trying to narrow the functions addressed by different SBG types. These two functions may co-reside within the same physical element or may be separated with a protocol acting as the interface between them.
• SBCs session border controllers
• IP- DSLAM Internet protocol based Digital Subscriber Line Access Multiplexer
• SBG features and functions can be found in, for example, MSF Session Border Gateway Requirements specification that is available at http://www.msforum.org/techinfo/approved/MSF-PS-SBG-001.00-FINAL.pdf.

• Certain drawbacks of utilizing infrastructure element-based implementation of SBG features and functions include:
• the present invention addresses these issues and, for example, enables service providers to allocate their budget for computing, communications, and control infrastructure development rather than creating and installing silos of computing and networking gears which very often either remain underutilized or become obsolete before reaching the full potential (or providing the full return on investment).
• a method that includes obtaining resource blocks for a signaling part of a session border gateway from a variety of networked resources, wherein the resource blocks are integrated into a pool and a unified view is presented to applications and services communicating with the signaling part of the session border gateway; controlling allocation of resources from a media part of the session border gateway via instructions over virtual private network links; obtaining resource blocks for the media part of the session border gateway from a variety of networked resources, wherein the resource blocks are integrated into a pool and a unified view is presented to the signaling part of the session border gateway; and using the resource blocks for the applications and services for a duration of time.

• FIG. 2 illustrates a Cloud-Based SBG implementation model.
• SBG functions dedicated computing, memory, and communications resources are required. These resources need to be integrated with the network infrastructure and operated in a harmonious way both in terms of traffic management and privacy/authentication/security administration.
• Cloud-Based SBG (CB-SBG) implementation overcomes the aforementioned drawbacks of traditional SBG implementation because there is no need to pre-allocate computing, memory, and communications resources— either stand-alone or n the infrastructure network elements— for the purpose of supporting the SBG features/functions. Instead, the resources are obtained from public, private, or community networks through open application and resource programming interfaces (APIs and RPIs).

It is notable that these APIs/RPIs not only simplify access to the desired resources, but also guarantee rapid integration and interoperability with the existing network/infrastructure, security, availability, service continuity, and the like. This is due to the fact that the desired SBG features/functions are obtained by selectively searching the available networked resources through open APIs/RPIs and fetching them so that they can be utilized per the requirements of the applications and services for the
