Passing a list of addresses to an Application

[Ivan Antoniv]

Hello,

I am relatively new to working with ns-3 so please bear with me if there is an obvious solution that I am not aware of.

I would like to pass a list of addresses (as opposed to simply one address as in most example I have found) to an application. If it is more convenient I can also pass an Ipv4InterfaceContainer.

note: I have looked around this board, but I could not find an answer :(

The closest discussion to this that I found was https://groups.google.com/forum/#!msg/ns-3-users/wvbUlng9Fo0/ehhnnweHORwJ but this thread did not end in a resolution :(

Thank You!

Hi,

it depends on if you need to have an Attribute holding these addresses, or you want to use a "normal" function to Set/Get them.

Normal Set/Get functions can safely use a container like a list, vector, map or whatever.

If you need attributes, then the link you found is the right starting place. Normally ObjectVectorValues are used to retrieve attributes, tho. I should study a but about how to use them to set values.

Hi,

Just one comment on this. It has been discussed previously (https://groups.google.com/d/msg/ns-3-users/rvdfvLVDowE/jLVHshUutaEJ); you can not SET vector variables with the attribute system.
You need to use a Set method after the object you want to set it to is initialized.

That sounds reasonable. Thank You! I actually tried doing something like this, but I was unsure of how to access the "Application object" (presumably from the helper I use to install the application) on which I wanted to call the Set function.

From the Node smart pointer you can get the applications that are installed on it.

(dynamic_cast<PkiMeshNode&> (*(m_hubNodes.Get(hubNum)->GetApplication(0))) ).setMeshAddresses(mesh_addresses)

Does this look like the right approach (PkiMeshNode is the name of the application I am building)?
