● The Crocodile SDK provides an easy to use API enabling rapid development of real-time communication applications
● The only thing that limits what you can do is your imagination
● The Crocodile SDK interacts with our web-service and wraps a SIP client stack, XMPP client stack, and MSRP client stack.
The Crocodile SDK
<html><script src="http://www.example.com/jquery.crocsdk.js"></script><script>$(document).ready(function(){ var croc = $.croc({ apiKey: "1dsku21#459821wks8=", });
var session = croc.media.connect("sip:bob@example.com"); session.remoteAudioElement = $('#audio');})</script>
<body> <audio id="audio" /></body></html>
Code Example
● The Web Service provides a json API for provisioning and management.
● The Crocodile SDK uses the Web Service● Third-party websites can interact directly with
the Web Service● All access is over HTTPS
The Crocodile Network (Web Service)
● SIP Edge Proxy, XMPP Connection Manager, MSRP Relay, TURN Server
● All traffic from the SDK uses WSS● WSS connections are authenticated● Hosted traffic is routed into the Network Core
– We can host domains
● Remote traffic is routed to the remote network it belongs to– We are just another interconnect
The Crocodile Network (Network Edge)
● SIP Proxy/Registrar● XMPP Server● Pre-Pay Application Server● Billing Server
● Traffic must come from the Network Edge
The Crocodile Network (Network Core)
● All traffic connecting to the network is secure (HTTPS and WSS)
● The MSRP Relay and TURN Server use ephemeral credentials
● Amazon AWS Multi A-Z Deployment– EC2 servers with RDS database
– SES for email and Route 53 for DNS
– Elastic Beanstalk for web-services
– ElastiCache, Redshift, and DynamoDB
Security, scalability, and reliability
● John Parr and Peter Dunkley will be at “WebRTC Conference and Expo”, Atlanta, 25 – 27 June 2013– Peter Dunkley participating in the “Making the Right
Signalling Choices” session
