<tt>Hello Ravitez,<br>
<br>
OK, so you see data being pending for reading from UAS - are you
sure the outbound TCP is the bottleneck ? have you tried to set
some thresholds on the script to see what the slowest part ? Maybe
it is not TCP related.<br>
<br>
Best regards,<br>

<br>
yes, there will be only one connection between
OpenSIPS and SBC, which will be shared between all
the SIP workers. In OpenSIPS TCP, there is no
concept of "connection per child". Still, what is
the kind of congestion you are experience ? could
you provide here some more details ?<br>

<div> Thank you for reaching out.</div>
<div> Considering the below example,though we have
multiple UAC</div>
<div> opensips creates only one tcp connection to
SBC which is valid because it only sees the SBC</div>
<div> but this creates congestion and in few
scenarios opensips creates too many tcp connections(bug).</div>
<div> in order to solve this i was thinking if we
can have 1 tcp connection per child.</div>
<div> Please share your thoughts.</div>

<div bgcolor="#FFFFFF" text="#000000"> <tt>Hi Ravitez,
OpenSIPS is doing connection reusage, so, if there IP
destination is the same, the existing connection will be
used.
Why do you want to change this ?

<div> I have been using opensips 1.11.5 as a proxy between
the application server and clients,things were fine as each
client had a dedicated tcp connection to opensips.</div>
<div> once i introduced SBC ,opensips has only one TCP
connection to SBC .would it be possible to create multiple TCP
connections to the same destination?.</div>
<div> eg :</div>
<div> Each child having a TCP connection to the same

<div>
</div>
<div> from what i understand is if a tcp connection exists
to a destination opensips passes on the fd to a requesting
child to send data.</div>
