uspControllerUseTcpOffload

Value Type

keyword-list

Accepted Values

yes | no

Default Value

yes

Description

Determines the TCP stack used in the USP Controller’s communications. If this value is set to yes, CDRouter’s USP Controller will use the Linux TCP stack for all communication with the USP Agent. For WebSocket this applies to both connections the USP Agent makes to the Controller and connections the Controller makes to the USP Agent.

The Linux TCP stack offers improved performance but requires Linux kernels 2.6.35 or newer. Previous versions of CDRouter and systems using kernels older than 2.6.35 will continue to use CDRouter’s native TCP stack.

CDRouter’s native TCP stack can also be forced, regardless of the kernel installed, by setting this testvar to a value of no.

This testvar was added in CDRouter 15.4
