Bias-Free Language

The documentation set for this product strives to use bias-free language. 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.

With this release, the TCP parameters are modified to reduce buffer overflow.	21.14.10
First introduced.	Pre 21.2

Feature Changes

Previous Behavior: In releases earlier to 21.14.x, the TCP slow start after idle time does not transfer the data from the buffer, thereby causing a buffer overflow.

New Behavior: From this release onwards, the TCP slow start is implemented only for the first TCP transfer. The TCP parameters are modified to reduce buffer overflow.
