4 Introduction to QUIC Flow Control
5 ---------------------------------
7 QUIC flow control acts at both connection and stream levels. At any time,
8 transmission of stream data could be prevented by connection-level flow control,
9 by stream-level flow control, or both. Flow control uses a credit-based model in
10 which the relevant flow control limit is expressed as the maximum number of
14 It is important to note that both connection and stream-level flow control
15 relate only to the transmission of QUIC stream data. QUIC flow control at stream
18 again, this still only counts as one byte for the purposes of flow control. Note

16 - As packets can be received before application calls SSL_read() to read
18 - The application should be able to set the limit on how much data should
19 be stored. The flow controller should be used to limit the peer to not send
20 more data. Without the flow control limit a rogue peer could trigger
21 a DoS via unlimited flow of incoming stream data frames.
22 - After the data is passed via SSL_read() to the application the stored
23 data can be released and flow control limit can be raised.
24 - As the peer can recreate stream data frames when resending them, the
