Constants

const DefaultAckDelayExponent = 3

DefaultAckDelayExponent is the default ack delay exponent

const DefaultActiveConnectionIDLimit = 2

DefaultActiveConnectionIDLimit is the default active connection ID limit

const DefaultMaxAckDelay = 25 * time.Millisecond

DefaultMaxAckDelay is the default max_ack_delay

const InvalidPacketLimitAES = 1 << 52

InvalidPacketLimitAES is the maximum number of packets that we can fail to decrypt when using AEAD_AES_128_GCM or AEAD_AES_265_GCM.

const InvalidPacketLimitChaCha = 1 << 36

InvalidPacketLimitChaCha is the maximum number of packets that we can fail to decrypt when using AEAD_CHACHA20_POLY1305.

const MaxAckDelayExponent = 20

MaxAckDelayExponent is the maximum ack delay exponent

const MaxByteCount = ByteCount(1<<62 - 1)

MaxByteCount is the maximum value of a ByteCount

const MaxConnIDLen = 20

MaxConnIDLen is the maximum length of the connection ID

const MaxLargePacketBufferSize = 20 * 1024

MaxLargePacketBufferSize is used when using GSO

const MaxMaxAckDelay = (1<<14 - 1) * time.Millisecond

MaxMaxAckDelay is the maximum max_ack_delay

const MaxPacketBufferSize = 1452

MaxPacketBufferSize maximum packet size of any QUIC packet, based on ethernet's max size, minus the IP and UDP headers. IPv6 has a 40 byte header, UDP adds an additional 8 bytes. This is a total overhead of 48 bytes. Ethernet's max packet size is 1500 bytes, 1500 - 48 = 1452.

const MinConnectionIDLenInitial = 8

MinConnectionIDLenInitial is the minimum length of the destination connection ID on an Initial packet.

const MinInitialPacketSize = 1200

MinInitialPacketSize is the minimum size an Initial packet is required to have.

const MinStatelessResetSize = 1 + 20 + 4 + 1 + 16 /* token */

MinStatelessResetSize is the minimum size of a stateless reset packet that we send

const MinUnknownVersionPacketSize = MinInitialPacketSize

MinUnknownVersionPacketSize is the minimum size a packet with an unknown version needs to have in order to trigger a Version Negotiation packet.
