This project is developing Service Discovery API emulation library. Service Discovery means a browser discovers local web services automatically under IP multicast technology such as UPnP and mDNS. To realize IP multicast communication via udp in current browser, utilizing chrome extension's raw socket api (experimental feature).

Demo

The library (now developing UPnP support only...) enables "Networked Service Discovery and Messaging" proposed by Opera and CableLabs. To enable IP Multicast in current browser, installing chrome extension is required.

The extension is depends on Raw Socket API (Chrome Extension's API). Because using this api, currently this extension only works under Chromium (I found that r148782 works well). Please note that this api doesn't work current Google Canary channel and Dev channel, I guess this is due to moving chrome.experimental.socket to chrome.socket.

• Navigate to chrome://flags/ in Canary, and enable 'Experimental Extension APIs'
• Navigate to chrome://chrome/extensions/ and enable Developer Mode.
• Download the packed extension
• Drag and drop the file into chrome://chrome/extensions and follow the prompt to install (if required).

With extension, including this library enables service discovery features in your site.

Please note that this library is quite experimental, you shouldn't use it in productive purpose.
