[OpenSIPStack] OSBC - load balancing

Hello,
I saw in some descriptions for OpenSBC that this can be configured to load balance sessions across
other instances. Each instance may be run on separate servers.
For example: I have 2 instances of OpenSBC. Every of them runs on a PC.
How can I configure this 2 instances to make load balancing?

Regards,
Costin Bularca

You can configure OpenSBC as a load balancer. You are going to need to
run the load balancer instance in one of your two boxes. The load
balancer should be configured to run in ProxyOnlyMode. Then in Relay
Routes, you can specify the address of the other two instances of opensbc

Example:

[*] sip:opensbcipaddress_1:5080 | sip:opensbcipaddress_2:5060

Re: [OpenSIPStack] OSBC - load balancing

Hi,

How is load balancing accomplished with the newer versions of OpenSBC?

I have 2 (OpenSBC)servers which should communicate with with 1(OpenSBC) Load Balancing instance .

In the newer versions i dont see the relay routes. In Proxy-Rela-Routes i see seperate fields. The information filled in this menu is not enough to get the load balancer do "load balancing".

Regards,

Imran

You can use the OpenSBCGroomer under Tools/OpenSBCGroomer to do the
load balancing for you. It goes with a sample XML file to demonstrate
routing.

Re: [OpenSIPStack] OSBC - load balancing

Hi,

Thanks for such a fast answer.
I'm using the RC1 of OpenSBC. There isnt such file file under Tools. Under Tools there is: SBCLaunchPad SQPlus Tail. Is it a feature coming with the cvs?

Re: [OpenSIPStack] OSBC - load balancing

Hi,

I installed the CVS version of OpenSBC.
However, I did not manage to get Load balancing work with the osbcgroomer.

I used the XML example (which came with the OpenSBCGroomer) and adjusted wioth my own IP's. I put the file in the same directory as the ossgroomer (obj_linnux_d)
I start it in the shell with "./osbcgroomer -r route.xml -i sip:ip.x.x.x:5060 " where the IP is the server.
I get a notification "Enable to load Route File" (where I believe the developer meant unable?)

If my set up is

Internet -> OpenSBC_Load_Balancer -> (OpenSBCserver1 | OpenSBCserver2)

How will I let the LB communicate in load balancing way with either server1 or 2?
I'm new into the OpenSBC project and did not find any trail to do Load balancing with OpenSBC.
If there is any document regarding this I'm very interested in it.

One other point:
http://www.opensourcesip.org:8080/clearspacex/docs/DOC-1031 I came across this document, but its for the older version of OpenSBC. Is there such document for the 1.1.5 version of OpenSBC? Is it possible to do Load balancing within the GUI of OpenSBC?

Any help would be apreciated.

regards,
Imran

Re: [OpenSIPStack] OSBC - load balancing

Hi,

I tried much today to get the OpenSBC do load balancing. I did not succeed.
I would appreciate help if one knows:

How to make xml such way that the servers1 and 2 will accept calls from LB
Where to put these scripts? (how could they be started?) The startup procedure?

TiA.

Imran
