Please read the SS7 documentation from 2.0.0.BETA1 http://code.google.com/p/jss7/wiki/Downloads?tm=2

The sctp create association specifies how you can pass additional IP's

Hello Amit

i did it as the doc say by using comma (,)

sctp association create STPHLR2 CLIENT 10.1.3.66 2905 10.1.3.83 2905 ---> working fine 

sctp association create STPHLR3 CLIENT 10.1.3.27,10.1.3.155 2905 10.1.3.83 2906  --> not working

another Q why it say:- No AS found for routing message TransferMessage:

13:06:46,867 ERROR [AssociationImpl] Error while initiating a connection

Hello!

>sctp association create STPHLR3 CLIENT 10.1.3.27,10.1.3.155 2905 10.1.3.83 2906

If 10.1.3.27,10.1.3.155 are two local addresses try this:
sctp association create STPHLR3 CLIENT 10.1.3.83 2906 10.1.3.27,10.1.3.155 2905

[Loay Mohammed]

Hello  Sergey 

they are not local addresses,

I have 4 HLR's :

HLR1 (1 IP), HLR2 (1 IP), HLR3 (2 IP's), HLR4 (2 IP's)

1st problem: Association  up only  if i connect to HLR which have 1 IP

second problem: HLR 3 and HLR 4 has 2 IP's when i try to multi-home it is notworking

I need the Association up to all HLR's

Hello!

Can you give me which ID addresses are local for Mobicents, which are remote and which "sctp association create" command do you use.

Hello!

> sctp association create STPHLR3 CLIENT 10.1.3.27,10.1.3.155 2905 10.1.3.83 2906

AFAIK you can leave the one of two HLR's addresses, for example
sctp association create STPHLR3 CLIENT 10.1.3.27 2905 10.1.3.83 2906
or
sctp association create STPHLR3 CLIENT 10.1.3.155 2905 10.1.3.83 2906

HLR itself when configuring SCTP defines both local addresses (10.1.3.27 and 10.1.3.155) for usage by SCTP.

But if you have two IP addresses at Mobicents side you must define both of them (if there addresses for example 10.1.3.83 and 10.1.3.84):
sctp association create STPHLR3 CLIENT 10.1.3.27 2905 10.1.3.83,10.1.3.84 2906

Hi all,

          I really don't get it :) , I have the same problem. My HLR has 2 IP addresses and when it falls back to the second one this happens:

16:49:55,745 WARN  [AssociationHandler] (Thread-17) Peer Address changed to=/10.100.63.19:46603 for Association=assoc1

...the primary being 10.100.63.3 which I have defined in the association.

an then :

 

16:50:33,266 ERROR [AssociationImpl] (Thread-17) IOException while trying to write to underlying socket for Association=assoc1 IOError count=1

java.net.BindException: Cannot assign requested address

        at org.mobicents.protocols.sctp.SelectorThread.run(SelectorThread.java:151)

        at java.lang.Thread.run(Thread.java:722)

So how do I define the second IP: 10.100.63.19 in the association ? :) 

My association:

mobicents(10.117.1.246:3435)>sctp association show

ASSOCIATION SCTP name=assoc1 started=true peerIp=10.100.63.3 peerPort=2998 server=add type=SERVER

This says that multihoming is configured propely and Association tried to switch to the second address.

16:50:33,266 ERROR [AssociationImpl] (Thread-17) IOException while trying to write to underlying socket for Association=assoc1 IOError count=1

This was the bug that has been fixed:

Hi, thank you for the answer.

The thing is that I haven't configured multihoming, I understood that I need to configure multihoming if I have 2 IP interfaces on my mobicents server. But I have 2 IP addresses on my HLR which conects to my mobicents server, and the HLR switches from 10.100.63.3 to 10.100.63.19. And when it does this, my mobicents server dosen't know about that second address. That's the issue. 

[Sergey Vetyutnev]

Hello!

For HLR multihoming (two IP addresses at HLR side): you should configure it at HLR side.
At Mobicents side you configure one of HLR addresses. AFAIK SCTP protocol itself gives info to the Mobicents Association that HLR has two IP addresses.
If Mobicents have two IP addresses you should specially configure this.

Hi Sergey,

I'm facing a similar problem.  

Let say if the network of the peer address (HLR's primary address) specified in the Mobicents Client Association is down, how could the HLR inform Mobicents about the other IP address?  The association has not been established yet.

Thanks.
