For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Enabling TCP Congestion Avoidance on SX500 Series Stackable Switches

Objective

TCP Congestion Avoidance is a technique which includes additive increase or multiplicative decrease and slow start schemes to avoid congestion in the network. When a TCP session is established, it is highly possible that network congestion can result between the TCP end points, which results in the loss of segments transmitted. Flow control does not address congestion problems, to address these problems a set of congestion avoidance algorithms are introduced. These algorithms allow TCP to better prioritize important packets which helps avoid congestion.

The objective of this document is to explain how to enable TCP congestion avoidance on Sx500 Series Stackable Switches.

Applicable Devices

• Sx500 Series Stackable Switches

Software Version
