[ndnSIM] Rocketfuel Topologies

[mdparamartha95 at students.itb.ac.id]

Hi Klaus and Alex 

Thank you for the reference on Github Klaus. However, the example seems like not working for me. 
But thank you at all, 

Alex gives me .txt file which can be imported instantly into annotated-topology-reader. 

Thank you to Alex too, 

However Alex, I got another question after I ran the simulation using --vis or NetAnim, the topology looks very complex, is that the old.txt based file not out of date to simulate the NDN? 

Thank you, 

Best Regards, 
Adi Paramartha

There are simpler ways of working with rocketfuel topologies. Check this old repository https://github.com/cawka/ndnSIM-sample-topologies 

It may not compile with the latest versions ndnSIM, but you can simply borrow the converted topologies. See the readme regarding what has been changed/inferred in the topologies.

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? 



Here is an example from ns-3: 
https://github.com/nsnam/ns-3-dev-git/blob/master/src/topology-read/test/rocketfuel-topology-reader-test-suite.cc 


BQ_BEGIN

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

Thank You,

Adi Paramartha

First you download the rocketfuel data from 
https://research.cs.washington.edu/networking/rocketfuel/ 

It comes in two formats: 

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

These can be used with the 
RocketfuelTopologyReader::GenerateFromMapsFile() function 
(https://www.nsnam.org/doxygen/classns3_1_1_rocketfuel_topology_reader.html) 


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

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, 
Klaus

Hello ndnSIM users, 

I would like to simulate the replacement scenario on a bigger scale, 
I found Rocketfuel topologies map reader in ndnSIM module, but there are 
no examples related to it... 

Could somebody give me some advice to start with Rocketfuel topology reader? 

Thank You
