Simple Network Framework

Open Source project for network discovery protocols.

Why not twisted, Tornado and etc?
- This framework purpose is to be lightweight and use the minimum external dependencies as possible
Protocols planned for implementation:
- UPnP / SSDP - Done
- mDNS - TODO
- SLP - TODO

#SSDP Discovery

Running with playground.py * Test & learning sample *
