Re: [Detnet] Available ISP topologies in academic work

Hi Antoine,
What do you think of Internet topology zoo (http://www.topology-zoo.org/)?

We may try Boston University Representative Internet Topology Generator 
(http://www.cs.bu.edu/brite/)
(/I have not used it myself for quite sometime because it is no longer 
supported by its developers. But General questions on using BRITE can be 
asked at brite-users@cs.bu.edu. You may subscribe to this list by sending /
/a blank email to brite-users-request@cs.bu.edu with the body of the 
email containing "subscribe" (without the quotes). You may also browse 
the list archives here <http://www.cs.bu.edu/lists/brite-users/>.). It 
is used by Denissa Ghrita in her research and Ph.D thesis on practical 
network tomography (circa 2012).

I recall a Telefonica presentation in IETF 114 about "*Exposure of 
Telefonica network topology through ALTO for integration with Telefonica 
CDN*" (5G transport network benchmarking <draft-contreras-bmwg-5g-00> 
(ietf.org) 
<https://datatracker.ietf.org/meeting/114/materials/slides-114-mops-exposure-of-telefonica-network-topology-through-alto-for-integration-with-telefonica-cdn-00>)

I have seen recent research on network tomography.  Examples include:
1) Traffic rate network tomography with higher-order cumulants 
(https://onlinelibrary.wiley.com/doi/pdfdirect/10.1002/net.22127?download=true). 
Published in Oct 2022.
2) A QoS-aware Mechanism for Reducing TCP Retransmission Timeouts using 
Network Tomography ((IJACSA) International Journal of Advanced Computer 
Science and Applications,
Vol. 14, No. 9, 2023)
3) A Boolean Network Tomography based Method for Deterministic 
Multi-point Fault Detection | IEEE Conference Publication | IEEE Xplore 
<https://ieeexplore.ieee.org/document/9685704> (Globecom 2021). This one 
is applicable to TSN.
4) PAINT: Path Aware Iterative Network Tomography for Link Metric 
Inference (PAINT_XUE_DOA30072022_AFV.pdf (ed.ac.uk) 
<https://www.pure.ed.ac.uk/ws/portalfiles/portal/306414237/PAINT_XUE_DOA30072022_AFV.pdf>)
5) ... there are other papers ....

Comments?

    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,

    Antoine Fressancourt
