Inter-AS intra-AS routing test

[Nirmala Shenoy]

Hello I would like to set up several AS with a maximum of 15 nodes and then connect 7 of these ASes. This would take 105 nodes. is it possible to reserve this many nodes in a slice?

Would it be more reasonable to reserve for each AS in a site and then connect them.

We plan to conduct some performance studies of inter-AS and intra-AS communications.

At least in my experience you are not likely to succeed getting a single slice this large in one shot. One of two things is a better approach:

1. Build separate slices (if you are using FABNetv4 or FABNetv4Ext it is easy to get them all to communicate with each other)
2. Build up a single slice by growing it via ‘modify’ (if a modify fails on a given site because it is out of resources, you move on to the next to get more nodes)

I am not sure (2) is worth the trouble for what you are describing.

I have this artifact notebook that shows how to do (2), but again, for your example I wouldn’t worry about this

Thanks Ilya.

Any jupyter examples that I can use to test option 1?

 

thanks

I think this example creates multiple slices to test MTU between sites
