Hi Leonadro,

I'm adding some relevant OPS-related lists, FWIW:

  *   OPSAWG as this is our main OPS entry point
  *   IPPM/BMWG: on the methodology for aggregating metrics and calculating=
 quality scores

Cheers,
Med (OPS Area Director)

Objet : [Int-area] Enhancing traceroute with contextual per-hop analysis (T=
raceroute Aurix)




Hi all,

My name is Leonardo Melegassi, a network and telecommunications engineer an=
d the creator of the Catellix project.

I have been working on a practical approach to extend traditional tracerout=
e diagnostics, called "Traceroute Aurix", which is already implemented and =
running in real-world scenarios.

While tools such as traceroute and MTR provide path discovery and continuou=
s measurements, they can be limited in exposing contextual behavior of each=
 hop and overall route quality in a structured way.

Aurix focuses on building a more analytical and enriched view of the path b=
y combining multiple dimensions of measurement and context.

In practical tests, the system is able to:

- Identify each hop with ASN and geolocation enrichment
- Measure per-hop minimum, average, and maximum latency, as well as jitter
- Evaluate the quality of each segment of the route
- Aggregate end-to-end metrics such as average latency, peak latency, and a=
n overall quality score
- Detect route consistency based on response rate and packet loss behavior

Additionally, the approach includes:

- Route discovery
- IP metadata enrichment
- Correlation analysis across hops

In one test case, traditional traceroute did not clearly expose route insta=
bility, while Aurix highlighted latency variation and per-hop consistency, =
making the issue more evident.

The goal is to evolve network diagnostics from a purely descriptive output =
to a more analytical model that can support pattern identification, trouble=
shooting, and operational decision-making.

I would appreciate feedback from the community, particularly regarding:

- The relevance of this approach
- Possible overlap with existing tools or ongoing work
- Potential directions for experimentation or standardization

I would be happy to share technical details, sample outputs, or further dat=
a if there is interest.

Best regards,
Leonardo Melegassi
