Hi Klaus,

Thank you for the quick information...

I already read the documentation, so the topology reader comes from NS-3 environment.
Not from ndnSIM/utils/topology.

Could you help me to provides some examples on how to convert it?

Since there are no examples to run the function in a proper way.

Thank You,
Best Regards,
Adi Paramartha

First you download the rocketfuel data from

It comes in two formats:

1. "ISP Maps (SIGCOMM 2002)" in .cch format.

These can be used with the
RocketfuelTopologyReader::GenerateFromMapsFile() function

2. "Backbone topologies annotated with inferred weights and link
latencies (IMW2002)" which come in a "weights.intra" and "latency.intra"

You can read these with RocketfuelTopologyReader::GenerateFromWeightsFile().

I think you want the second option for the 6 rocketfuel topologies that
everyone uses (Exodus, Ebone, Telstra, Abovenet, Tiscali, and Sprint).
The first option are vastly larger topologies (thousands of nodes) and
less commonly used.

Also consider that GenerateFromWeightsFile() only supports reading the
link weights/metrics, but not the link latency or bandwidth. Thus, you
need to set those values manually.

Best regards,
