Hello,


 I would like to test Sctp multihoming with the simulator and mobicents server.

The simulator is the client, it initiate the connection and the mobicents is the server

The use case that i would like to test is the following 


The mobicents has 2 IP =>  IP A and IP B the two adresses bind on port 2905
The client has  2 IP too => IP C and IP D  the two adresses bind also on port 2905

The association must start with IP C= >IPA and if there is a problem with this link switch with IP D => IP B.

My question is about the different command in mobicents ss7 cli  to declare :

sctp server create mbc1 IP A,IP B 2905 
sctp server start mbc1
sctp association create assmbc1 SERVER mbc1 IPC,IPD 2905

Is my configuration for  the server side ok ( IP A will be associate to IP C and IPB with with IPD)?

for the simulator side can we simulate multi homing with one simulator with 2 adresses or   need we two instances?

Thanks in advance,

Best Regards,

Mehdi

Hello,

You need to specify for home routing extra addresse only for host side, not for peer side.

So for server side:
sctp server create mbc1 IPA,IPB 2905 
sctp server start mbc1
sctp association create assmbc1 SERVER mbc1 IPC 2905

In SS7 Simulator:
SCTP local host: IPC
SCTP extra host addresses: IPD

Hello Sergey ,

Thank you for you answer :)

I tried but i think i forgot something in the configuration because i had these error :

2015-01-22 09:11:58,134 WARN  [org.mobicents.protocols.sctp.SelectorThread] (Thread-23) Received connect request from non provisioned 192.168.194.140:2905 address. Closing Channel :S

If you have any idea ?


Thanks in advance.

Best Regards.

Mehdi
