TFX platform

So I haven’t written anything worthy in a while , just published some posts that were lying around in my drafts . Here I write about the main thing . some thing awesome that I was trying to accomplish in the last quarter .

<< TFX is now live in chrome store , open and free for public use . No signin or account required , no advertisements   : https://chrome.google.com/webstore/detail/tfx-sessions/aochimdcllmgleokpnlabijehdlmkdga >>

TFX Sessions is a plug and play platform for VoIP ( voice over IP ) scenarios.  Intrinsically it  is a very lightweight API package and shipped in form of a Chrome Extension . It is a turn-key solution when parties want instant audio/audio communication without any sign-in ,plugin installation or additional downloads  . Additionally TFX Sessions is packaged with some interesting plugins which enable the communicating parties to get the interactive and immersive experience as in a face to face meeting.

There is a market requirement of making a utterly simple WebRTC API  that has everything needed to build bigger aggregate projects but the available solutions are either just to basic or much too complex . So I initially started writing my own getuserMedia APIs, but left it midway and picked up simplewebrtc API instead for want of time .Then I focused on the main crux  of the project which was the widget API and ease of integration.

How Does TFX Sessions Work ?

  • Signalling channel establishes the session using Offer- Answer Model
  • Browser’s  media API’s , like getUserMedia and Peerconnection are used for media flow
  • Media only flows peer to peer

A Widget is essentially any web project that wants communication over webrtc channel . Once the platform is ready I have core APIs , widgets and signalling server. Then came up the subject of enterprise internet blocking my communication stream . Time for TURN ( Coturn in my case ).

Components of TFX

Client Side Components of tangoFX :

broplug API
Inhouse master library for TangoFX. Makes the TFX sessions platform .Masks the low level webrtc and socketio functions .
Provides simple to use handles for interesting plugins development in platform .
simplewebrtc
performs webrtc support , peer configuration , wildemitter , utils , event emitters , JSON formatter , websocket , socket namespace , transport , XHR more like so
socket.io.js
exports and listener for real time event based bidirectional communication
Jquerry
JS library for client side scripting
Bootstrap
HTML and CSS-based design templates for typography, forms, buttons, navigation and other interface components.

Server Side components

Signalling Server -signal master
socket.io server for webrtc signalling
TURN -Coturn
TURN protocol based media traversal for connecting media across restricting domains ie firewalls, network policies etc .
redis Data structure to maintain current and lost sessions

Architecture

So here is the final architecture of TFX chrome extension widget based platform .

  • The client side contains widgets , chore extension APIs , chrome’s WebRTC API’s , socket.io client for signalling , HTML5 , Jquerry , Javascript , and CSS for styling.
  • The Server Side of the solution contains socket.io server for signalling , manuals and other help/support materials , HTTPS certificate and TURN server implementation for NAT .

Salient Features

  • The underlying technology of TangoFX is  webrtc with socket based signalling  . Also it adheres to the latest standards of W3C , IETF and ITU on internet telephony .
  • TangoFX sessions is extremely scalable and flexible due to the abstraction between communication and service development. This make it a piece of  cake for any web developer using  TangoFX interface to add his/ her own service easily and quickly without diving into the nitty gritties .
  • TangoFX is currently packaged in a chrome extension supported on chrome browser on desktop operating system like window , mac , linux etc .
  • The call is private to both the parties as it is peer-to-peer meaning that the media / information exchanged by the parties over TangoFX does not pass through an intervening server as in other existing internet calling solutions.
  • TangoFX is very adaptive to slow internet and can be used across all kinds of networks such as corporate to public without being affected by firewall or restricting policies  .

TFX Widget Screens

Alright so that’s there . Tada the platform is alive and kicking . Right now in beta stage however . Intensive testing going on here . However here are some screenshots that are from my own developer version .
