assigning unique strings/names to network interfaces in a simulation.

[hardik soni]

Hi All,

I want to assign unique names/strings to the network interfaces in a simulator process.

ns-3 assigns name/string to interface unique within a node.

For example,

if a simulation script has 2 nodes have 2 network interfaces each.

Both nodes would have interfaces named sim1 and sim2.

I want sim1, sim2 to interfaces of one node and sim3,sim4 to interfaces of another node. 

I want to assign unique string across the simulation not across the interfaces in one particular node.

It will help me in debugging my scenario in ns-3.

Thanks,
Hardik Soni

Hi,

it's a problem of name assignments I guess. I'd suggest to use a string composition in the main loop, and to assign names from there.

I can't help more if I don't see how you actually build the various nodes and their interfaces, but it's definitely possible.

Cheers,

T.

Thanks.

I was searching for an API to set the name of NetDevice object directly.

But, "ns3::NetDevice::SetIfIndex" may help me to achieve the same. need to check.

Yo,

check this: "examples/naming/object-names.cc"

It does what you want (more or less).

Cheers,

T.

Hi,

I am not doing anything special to build nodes and interfaces, yet.

below is the code snippet.

------------------------------------------

CsmaHelper csma;
devices = csma.Install (NodeContainer (nodes.Get (0), nodes.Get (1), nodes.Get (4)));

NetDeviceContainer dev14 = csma.Install (NodeContainer (nodes.Get (1), nodes.Get (4)));
NetDeviceContainer dev12 = csma.Install (NodeContainer (nodes.Get (1), nodes.Get (2)));
NetDeviceContainer dev43 = csma.Install (NodeContainer (nodes.Get (4), nodes.Get (3)));

------------------------------------------

I am looking for some API to set name of the NetDevice object. In my case it is CSMANetDevice object.

Ultimately everything comes from the "Object" class, so somewhere it should have facility to associate name of the object with its instance.

Thanks,
Hardik Soni
