‎Multiple streams within connections

Similar to SCTP, SSH and HTTP/2, QUIC features separate logical streams withinthe physical connections. A number of parallel streams that can transfer datasimultaneously over a single connection without affecting the other streams.

A connection is a negotiated setup between two end-points similar to how a TCPconnection works. A QUIC connection is made to a UDP port and IP address, butonce established the connection is associated by its “connection ID”.

Over an established connection, either side can create streams and send datato the other end. Streams are delivered in-order and they are reliable, butdifferent streams may be delivered out-of-order.

QUIC offers flow control on both connection and streams.
