An implementation of Interactive Connectivity Establishment (RFC 5245)
Project description
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.
Example
#!/usr/bin/env python
import asyncio
import aioice
async def connect_using_ice():
connection = aioice.Connection(ice_controlling=True)
# gather local candidates
await connection.gather_candidates()
# send your information to the remote party using your signaling method
send_local_info(
connection.local_candidates,
connection.local_username,
connection.local_password)
# receive remote information using your signaling method
remote_candidates, remote_username, remote_password = get_remote_info()
# perform ICE handshake
for candidate in remote_candidates:
await connection.add_remote_candidate(candidate)
await connection.add_remote_candidate(None)
connection.remote_username = remote_username
connection.remote_password = remote_password
await connection.connect()
# send and receive data
await connection.sendto(b'1234', 1)
data, component = await connection.recvfrom()
# close connection
await connection.close()
asyncio.get_event_loop().run_until_complete(connect_using_ice())License
aioice is released under the BSD license.
