Hello Ravitez,
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.

Hello Bogdan,
Good Day,
Congestion happens on the receive Q of opensips(UAS ->
opensips) when UAS tries to send ~3000 messages in one second.
and i see multiple tcp_connections being created to the
same destination (SBC) but based on the logic only the recent or the
last connection is
being used,when tcp_async is used i see readQ
(USA->opensips) not being read (still see n number of bytes).
Thank you.

Hello Ravitez,
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 ?

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

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 ? Best regards,

Hello,
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.
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?.
eg :
Each child having a TCP connection to the same
destination.
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.
please share your thoughts.
