OpenJDK 27 · jdk.internal.net.http.quic.packets.OneRttPacket

This class models Quic 1-RTT packets, as defined by RFC 9000, Section 17.3.1:

A 1-RTT packet uses a short packet header. It is used after the
   version and 1-RTT keys are negotiated.

   1-RTT Packet {
     Header Form (1) = 0,
     Fixed Bit (1) = 1,
     Spin Bit (1),
     Reserved Bits (2),         # Protected
     Key Phase (1),             # Protected
     Packet Number Length (2),  # Protected
     Destination Connection ID (0..160),
     Packet Number (8..32),     # Protected
     # Protected Packet Payload:
     Protected Payload (0..24), # Skipped Part
     Protected Payload (128),   # Sampled Part
     Protected Payload (..),    # Remainder
   }

Subclasses of this class may be used to model packets exchanged with either Quic Version 1 or Quic Version 2. Quic Version 2 uses the same 1-RTT packet structure than Quic Version 1.

See [QUIC-TLS] for details. This bit is protected using header protection; see Section 5.4 of [QUIC-TLS].` Returns:int the packet's Key Phase Bit See Also RFC 9001, [QUIC-TLS], RFC 9001, Section 5.4, [QUIC-TLS]
