Detailed Description

This is an implementation of various Transmission Control Protocol flavors.

Each TCP flavors is studied to match a specific environment, and they differ mainly in the congestion control algorithms used.

See RFC 793 and others.

Typedef Documentation

typedef void(* ns3::TcpSocketState::TcpCongStatesTracedValueCallback) (const TcpCongState_t oldValue, const TcpCongState_t newValue)

TracedValue Callback signature for TcpCongState_t.

Parameters

[in]	oldValue	original value of the traced variable
[in]	newValue	new value of the traced variable

Definition at line 163 of file tcp-socket-base.h.

typedef void(* ns3::TcpCongStatesTracedValueCallback) (const TcpSocketState::TcpCongState_t oldValue, const TcpSocketState::TcpCongState_t newValue)

TracedValue Callback signature for TcpCongState_t.

Parameters

[in]	oldValue	original value of the traced variable
[in]	newValue	new value of the traced variable

Definition at line 1257 of file tcp-socket-base.h.

typedef void(* ns3::TcpStatesTracedValueCallback) (const TcpSocket::TcpStates_t oldValue, const TcpSocket::TcpStates_t newValue)

TracedValue Callback signature for TcpStates_t.

Parameters

[in]	oldValue	original value of the traced variable
[in]	newValue	new value of the traced variable

Definition at line 262 of file tcp-socket.h.

TCP flag field values.

Definition at line 279 of file tcp-header.h.

The option Kind, as defined in the respective RFCs.

Enumerator
END	END.
NOP	NOP.
MSS	MSS.
WINSCALE	WINSCALE.
SACKPERMITTED	SACKPERMITTED.
SACK	SACK.
TS	TS.
UNKNOWN	not a standardized value; for unknown recv'd options

Definition at line 53 of file tcp-option.h.

Names of the 11 TCP states.

Enumerator
CLOSED	Socket is finished.
LISTEN	Listening for a connection.
SYN_SENT	Sent a connection request, waiting for ack.
SYN_RCVD	Received a connection request, sent ack, waiting for final ack in three-way handshake.
ESTABLISHED	Connection established.
CLOSE_WAIT	Remote side has shutdown and is waiting for us to finish writing our data and to shutdown (we have to close() to move on to LAST_ACK)
LAST_ACK	Our side has shutdown after remote has shutdown. There may still be data in our buffer that we have to finish sending
FIN_WAIT_1	Our side has shutdown, waiting to complete transmission of remaining buffered data.
FIN_WAIT_2	All buffered data sent, waiting for remote to shutdown.
CLOSING	Both sides have shutdown but we still have data we have to finish sending.
TIME_WAIT	Timeout to catch resent junk before entering closed, can only be entered from FIN_WAIT2 or CLOSING. Required because the other end may not have gotten our last ACK causing it to retransmit the data packet (which we ignore)
LAST_STATE	Last state, used only in debug messages.
