Suman,

As far as I know: You can't round robin TCP packets from a single
source IP - UNLESS the connection times out, i.e. you could reduce the
timeouts?
UDP has an OPS (one packet scheduler) - But it makes no sense for TCP.

Hi Malcolm,
Thanks for your prompt reply,
I have tried with keeping 5 seconds timeout value for TCP connection, but no improvement.
Command tried: ipvsadm --set 5 5 0
Do you think I missed something here? do you know any other algorithm which works with TCP?

Thanks in advance.

Regards,
Suman

Suman,

Are you testing with multiple clients?
If you only have one then - IF the single connection closes, then the
next one will just hit the same empty server.
Round Robin will work when you have more than one connection but
testing with a single client can be confusing.

Hi Malcolm,

I had tried with multiple client which works fine. i.e. LVS load balanced the packets between multiple real server if packet received from multiple clients.
But based on requirement LVS will get packets from a single client(same source IP and Port). Is there any tuning will help?
Thanks in advance

Regards,
Suman

Hi Suman,

I'm afraid not, it would be required that the three-way handshake
happens against one server with TCP traffic and then data is sent.

As such one client must talk to one server for a single ESTABLISHED
TCP connection.

UDP is different, it's stateless so no handshake so you can use
OPS(One Packet Scheduling) to spray packets in a round robin fashion,
another trick with UDP when not using OPS is setting the timeout for
UDP to 1 sec which can give you a pseudo OPS when it's not available.

No, new connections from one client will always terminate on the same real
server while at least one connection from that client to a real server is
open.

If you need real round robin forwarding of tcp connections from one client
to multiple real servers, have a look at haproxy in tcp mode.

Hi Thomas & Aaron,

Thanks for the explanation.
One question, does haproxy supports SIP over TCP?

Thanks & Regards,
Suman Pandit

HAProxy, although primarily a HTTP(S) proxy and loadbalancer, supports plain
TCP load balancing, too. As such, support for any protocol over TCP is
implied.

See http://cbonte.github.io/haproxy-dconv/1.8/intro.html#3.1

Thanks a lot guys for helping me to understand lvs internals.

Thanks & Regards,

No, new connections from one client will always terminate on the same real server while at least one connection from that client to a real server is open.

If you need real round robin forwarding of tcp connections from one client to multiple real servers, have a look at haproxy in tcp mode.
