In TCP connections implementing ABC, you can specify the rate of increase of the congestion window during the slow start phase. This limit enables you to improve TCP performance.
About this task
- You can increase the congestion window's limit only when ABC is used in TCP congestion control.
- In an HA pair, you must set the same value in both the nodes.
- The default value of this option is set to 2.
- If the rate at which the packets are dropped is increased, probably due to network congestion, then you should set the limit value to 1.
Step
- To specify the limit for increasing the congestion window, enter the following command:
options ip.tcp.abc.l_limit {1|2} 1—This is the value for a conservative increase of the congestion window.
