<p><strong>Slow start threshold.</strong> The current values for the slow-start

threshold and the congestion window are indirect indicators of the flow of data
|

through a TCP connection. These values are used by TCP as part of a congestion
|
||
|
|
control algorithm. This algorithm ensures that this system sends data at a slow
|
||
|
|
rate at first. After the first data has been successfully sent, the rate in
|
||
|
|
which data is sent increases. This change is made in a controlled manner that
|
||
|
|
is dependent on the amount of congestion in the network. Congestion control
|
||
|
|
occurs both at connection start time and when congestion is detected. The
|

|
|
values used for the slow-start threshold and the congestion window are

determined by TCP and cannot be set by the user.</p>

<p><strong>Slow start threshold.</strong> The current values for the slow-start

through a TCP connection. These values are used by TCP as part of a congestion

control algorithm. This algorithm ensures that this system sends data at a slow

rate at first. After the first data has been successfully sent, the rate in
|

|
|
which data is sent increases. This change is made in a controlled manner that

is dependent on the amount of congestion in the network. Congestion control
|

occurs both at connection start time and when congestion is detected. The
