Many of this structure's members follow RFC 793 section 3.2, "Terminology". Where applicable, the original name used in the RFC is indicated. Users are referred to RFC 793 for more information on these variables.

Members

• ntTcpSockDesc

  Socket descriptor.

• ntTcpBytesInRecvQ

  Data in the receive queue, in bytes.

• ntTcpBytesInSendQ

  Data in the send queue, in bytes.

• ntTcpRecvQSize

  Size of the receive queue, in bytes.

• ntTcpSendQSize

  Size of the send queue, in bytes.

• ntTcpLocalSockAddr

  Local address, port and protocol family information of the socket.

• ntTcpOwnerCount

  Owner count of the socket.

• ntTcpPeerSockAddr

  Peer's address, port and protocol family information of the socket.

• ntTcpFlags

  TCP flags.

• ntTcpRto

  Retransmission timeout.

• ntTcpReXmitCnt

  number of retransmitted segments.

• ntTcpSndUna

  Send Sequence Variables: SND.UNA - send unacknowledged.

• ntTcpIss

  Send Sequence Variables: ISS - initial send sequence number.

• ntTcpSndNxt

  Send Sequence Variables: SND.NXT - send next.

• ntTcpMaxSndNxt

  Highest sequence number sent (used because of retransmit).

• ntTcpIrs

  Receive Sequence Variables:IRS - initial receive sequence number.

• ntTcpSndWL1

  Send Sequence Variables: SND.WL1 - segment sequence number used for last window update SND.

• ntTcpSndWL2

  Send Sequence Variables: SND.WL2 - segment acknowledgment number used for last window update.

• ntTcpMaxSndWnd

  Maximum send window seen so far.

• ntTcpRcvNxt

  Receive Sequence VariablesRCV.NXT - receive next.

• ntTcpRcvWnd

  Receive Sequence Variables:RCV.WND - receive window.

• ntTcpRcvAdv

  Sequence number of right edge of advertized window. (Could be smaller than Rcv.Nxt+Rcv.Wnd to avoid silly window syndrome. Also used to prevent shrinkage of our receive window.)

• ntTcpCwnd

  Send congestion window.

• ntTcpSsthresh

  Send slow start threshold size.

• ntTcpBackLog

  Back logs.

• ntTcpDupAck

  Duplicate ACK's.

• ntTcpAcksAfterRexmit

  Number of non duplicate ACK's after duplicate ACK(s).

• ntTcpState

  One of the following:

• TM_NT_TCPS_CLOSED
• TM_NT_TCPS_LISTEN
• TM_NT_TCPS_SYN_SENT
• TM_NT_TCPS_SYN_RECEIVED
• TM_NT_TCPS_ESTABLISHED
• TM_NT_TCPS_CLOSE_WAIT
