IP Routing 3

TCP Statistics

The Transmission Control Protocol (TCP) provides highly reliable host-to-host connections in packet-switched networks, and is used in conjunction with IP to support a wide variety of Internet protocols.

 

Table 3-21 TCP Statistics

Parameter

Description

 

 

Segments Received

The total number of segments received, including those received in error.

 

This count includes segments received on currently established

 

connections.

Segments Sent

The total number of segments sent, including those on current

 

connections but excluding those containing only retransmitted octets.

Active Opens

The number of times TCP connections have made a direct transition to the

 

SYN-SENT state from the CLOSED state.

Failed Connection Attempts

The number of times TCP connections have made a direct transition to the

 

CLOSED state from either the SYN-SENT state or the SYN-RCVD state,

 

plus the number of times TCP connections have made a direct transition

 

to the LISTEN state from the SYN-RCVD state.

Current Connections

The number of TCP connections for which the current state is either

 

ESTABLISHED or CLOSE- WAIT.

Receive Errors

The total number of segments received in error (e.g., bad TCP

 

checksums).

Segments Retransmitted

The total number of segments retransmitted - that is, the number of TCP

 

segments transmitted containing one or more previously transmitted

 

octets.

Passive Opens

The number of times TCP connections have made a direct transition to the

 

SYN-RCVD state from the LISTEN state.

Reset Connections

The number of times TCP connections have made a direct transition to the

 

CLOSED state from either the ESTABLISHED state or the CLOSE-WAIT

 

state.
