public Interface VersionNegotiationPacket

extends LongHeaderPacket
Known Direct Implementers
jdk.internal.net.http.quic.packets.QuicPacketDecoder.IncomingVersionNegotiationPacket, jdk.internal.net.http.quic.packets.QuicPacketEncoder.OutgoingVersionNegotiationPacket
This class models Quic Version Negotiation Packets, as defined by RFC 9000, Section 17.2.1: 
A Version Negotiation packet is inherently not version-specific.
   Upon receipt by a client, it will be identified as a Version
   Negotiation packet based on the Version field having a value of 0.

   The Version Negotiation packet is a response to a client packet that
   contains a version that is not supported by the server, and is only
   sent by servers.

   The layout of a Version Negotiation packet is:

   Version Negotiation Packet {
     Header Form (1) = 1,
     Unused (7),
     Version (32) = 0,
     Destination Connection ID Length (8),
     Destination Connection ID (0..2040),
     Source Connection ID Length (8),
     Source Connection ID (0..2040),
     Supported Version (32) ...,
   }
