Parameters

QuicVersion

The QUIC version negotiated for the new incoming connection.

LocalAddress

This field indicates the local address of the new incoming connection.

RemoteAddress

This field indicates the remote address of the new incoming connection.

CryptoBufferLength

This field indicates the length of the crypto buffer.

ClientAlpnListLength

This field indicates the total bytes of the client ALPN list.

ServerNameLength

This field indicates the length of the server name (SNI).

NegotiatedAlpnLength

This field indicates the length of the negotiated ALPN.

CryptoBuffer

This pointer indicates the crypto buffer for the new incoming connection.

ClientAlpnList

This pointer indicates the sent ALPN list from the client via the new incoming connection.

NegotiatedAlpn

This pointer indicates the negotiated ALPN between server and client.

ServerName

This pointer indicates the server name (SNI) of the new incoming connection.

Note: this buffer comes directly from the TLS ClientHello, and its format is governed by TLS. From RFC 6066:

"HostName" contains the fully qualified DNS hostname of the server, as understood by the client. The hostname is represented as a byte string using ASCII encoding without a trailing dot. This allows the support of internationalized domain names through the use of A-labels defined in [RFC5890]. DNS hostnames are case-insensitive. The algorithm to compare hostnames is described in [RFC5890, Section 2.3.2.4].
