uva-rp2's Introduction

SOCKS over TURN

UvA / SNE/OS3 / RP2

ICE: complete framework for NAT traversal
STUN (RFC 5389): request / response of reflexive transport address (public host:port of client after NAT)
TURN (RFC 5766): relay data when direct p2p is unavailable
TURN Allocation: port on server for use by client, 10min refresh
TURN Permissions: server allowed peer, 5min refresh
TURN Send/Data: basic send/recv
TURN Channel: low overhead version of Send/Data, 10min refresh
TURN TCP: uses separate control / data connections for tcp, same refresh

client uses STUN to find it's publicly reachable address from a STUN server
client uses TURN to request an Allocation on a TURN server (with authentication)
client keeps the allocation using Refresh (default 10min), and deletes when done (Refresh 0s)
