target = "https://www.rfc-editor.org/rfc/rfc9000#section-5.1.1" [[exception]] quote = ''' If an endpoint provided fewer connection IDs than the peer's active_connection_id_limit, it MAY supply a new connection ID when it receives a packet with a previously unused connection ID. ''' reason = ''' s2n-quic proactively supplies connection IDs up to the minimum of the peer's active_connection_id_limit and a hardcoded MAX_ACTIVE_CONNECTION_ID_LIMIT, so the maximum amount of connection IDs will already be issued by the time a peer uses them. ''' [[exception]] quote = ''' An endpoint MAY limit the total number of connection IDs issued for each connection to avoid the risk of running out of connection IDs; see Section 10.3.2. ''' reason = ''' s2n-quic requires connection ID providers to provide connection IDs of at least 4 bytes in length, which allows for at least 4 billion possible connection IDs. s2n-quic allows limits the number of concurrent connection IDs issued, as well as their minimum lifetime, so the risk of running out of connection IDs is sufficiently mitigated.
