WebRTC

WebRTC (Web Real-Time Communication) is an API definition drafted by the World Wide Web Consortium (W3C) that supports browser-to-browser applications for voice calling, video chat, and P2P file sharing without the need for either internal or external plugins. Enables browser to browser media streaming over secure RTP profile Standardization, on an API level at the W3C and at the protocol level at the IETF. Enables web browsers with Real-Time Communications (RTC) capabilities written in c++ and javascript BSD style license free, open project available in all major browsers

WebRTC Stack Architecture and Layers

WebRTC offers web application developers the ability to write rich, realtime multimedia applications (think video chat) on the web, without requiring plugins, downloads or installs. It's purpose is to help build a strong RTC platform that works across multiple web browsers, across multiple platforms.

IMS , the revolution ahead

vision : To make a model that separates the services offered by fixed-line (traditional telcos),                mobile (traditional cellular),            and            converged service providers (cable companies and others who provide triple-play — voice,  video, and data — services) from the access networks used to receive those services. … Continue reading IMS , the revolution ahead

Telecommunications convergence – VoIP, PBX and IMS

The signalling protocols migration like from signalling system 7 (SS7) to session initial protocol (SIP) have been taking place in Telco-Industry. Similarly nodes of legacy network like signal transfer point (STP) of legacy network are being migrated to call session control function (CSCF) of IMS that allows the rapid development and deployment of enhanced, revenue-generating multimedia services for fixed, mobile and cable operators. IMS architecture enables operators to seamlessly run a plethora of next-generation converged services over their fixed, mobile and cable networks, achieve a faster time-to-market for new services and have fewer performance bottlenecks.

Service Broker 1

Service broker is a service abstraction layer between the network and application layer in  telecom environment. SB( Service Broker ) enables us to make use of existing applications and services from Intelligent Network’s SCP ( Service control Point ) , IMS’s Application Server as well as other sources  in a harmonized manner .
