[Detnet] Available ISP topologies in academic work

[Antoine FRESSANCOURT <[e-mail]>]

Hello,

Bouncing on the call for topologies to evaluate large scale DetNet proposals, I reminded some topologies I have been using during my PhD time, a few years ago. Unfortunately, some Internet tomography projects have stopped since then, and given the growing criticality of the Internet infrastructure, it seems that publicly available ISP-level topologies are difficult to get.

The reference project people go to when looking for ISP-level topologies is Rocketfuel (https://research.cs.washington.edu/networking/rocketfuel/). It is old but topologies extracted from this dataset are still used for routing mechanism evaluation.

Some specific ISP topologies have been refined and complemented with demands from flows in DEFO (https://sites.uclouvain.be/defo/). DEFO uses both real topologies from Rocketfuel and synthetic topologies generated with iGen (https://informatique.umons.ac.be/networks/igen/). The missing aspect in DEFO's augmented topologies is the lack of latency bounds or Jitter bounds for flows, inter-arrival times etc. . Maybe we can augment those topologies to fit with what we need as a group to evaluate large scale detnet options ?

Best regards,
