DSR TCP Window Size in All Messages Remains Very Low

(Doc ID 2406004.1)

Last updated on JUNE 04, 2018

Applies to:

Oracle Communications Diameter Signaling Router (DSR) - Version DSR 5.0 and later
Tekelec

Goal

Investigating why the Advertised Receive Window for TCP SWm is 7813.

Is the DSR broadcasting an advertised receive window of 7813 to be expected? This is fairly small considering the TCP default connection Socket Buffer in the platform is 1,000,000 bytes.
