9.4. TCP
The TCP Statistics screen provides statistical information about packets/connections using a TCP
protocol. Definitions and descriptions of each parameter are described below:
RtoAlgorithm :
Specifies the retransmission time-out (RTO) algorithm in use. The Retransmission Algorithm can
have one of the following values.
0 : CONSTANT - Constant Time-out
1: RSRE - MIL-STD-1778 Appendix B
2: VANJ - Van Jacobson' s Algorithm
3: OTHER – Other
RtoMin :
Specifies the minimum retransmission time-out value in milliseconds.
RtoMax :
Specifies the maximum retransmission time-out value in milliseconds.
MaxConn :
Specifies the maximum number of connections. If the maximum number is set to -1, the maximum
number of connections are dynamic.
ActiveOpens :
Specifies the number of active opens. In an active open, the client is initiating a connection with
the server.
