An implementation of Interactive Connectivity Establishment (RFC 5245)
What is aioice?
aioice is a library for Interactive Connectivity Establishment (RFC 5245) in Python. It is built on top of asyncio, Python’s standard asynchronous I/O framework.
Interactive Connectivity Establishment (ICE) is useful for applications that establish peer-to-peer UDP data streams, as it facilitates NAT traversal. Typical usecases include SIP and WebRTC.
To learn more about aioice please read the documentation.

aioice is released under the BSD license.
