Re: [bmwg] Considerations for Benchmarking Network Performance in Satellite Internet Constellations

Dear Al:

Thanks a lot for your suggestions! We fully agree that the scope of work should be determined in accordance with the charter.
 
IMO, I think that: (1) a series of recommendations concerning the network performance characteristics of inter-networking technologies for integrating future LEO satellites and terrestrial networks, and (2) benchmark methodologies for related LEO satellite devices/systems, should fit the BMWG charter. 
 
In particular, works fitting the charter may include:
 
(1) describing the class of network functions, systems, or services that play a critical role in emerging LEO satellite Internt. 
 
For example, the inter-networking approach for integrating satellites and terrestrial facilities, a new routing mechanism in an integrated space and terrestrial environment, or a user terminal for connecting LEO satellites.
 
(2) discussing the key performance characteristics that are pertinent to LEO integrated space and terrestrial networks.
 
For example, the coverage, user-perceived latency/bandwidth/jitter, etc.
 
(3) clarifying a set of important metrics that can help to describe the above characteristics.
 
For example, the constellation architecture, network topology, hardware capability of the ground facilities, etc.
 
(4) specifying the concrete methodology to reasonably collect the above characteristics.
 
(5) concrete benchmarking methodology and test cases.
 
(6) describing requirements for the result reporting format.
 
We elaborate our preliminary considerations in our submitted draft, and hope it can help to narrow down the work scope, and stimulate more discussions on benchmarking recommendations for the upcoming LEO satellite networks.
 
Thanks!

Best regards,
Zeqi Lai

Thanks for this update, Zeqi Lai.
 
Speaking as a participant, I think that LEO satellite technology may see more common usage in our communications of the future. It would be worthwhile to discover the scope of work that fits the bmwg charter, so that this WG can play a useful role in the big LEO picture.
 
regards,
Al

Dear BMWG:
 
Hope this email finds you all well!
 
Last time we reported our preliminary considerations for the problems and requirements of of evaluation methodology for futuristic integrated space and terrestrial networks. (you can find our previous slides here: https://datatracker.ietf.org/doc/slides-112-bmwg-problems-and-requirements-of-evaluation-methodology-for-integrated-space-and-terrestrial-networks/00/). We got a lot of valuable advice from that meeting. Many thanks!
 
We are still working on this timely topic. Recently, according to our latest research progress, we make several new considerations for benchmarking the network performance of emerging satellite Internet constellations.
 
Specifically, we describe these aspects that are mostly related to the network performance benchmarking for recent satellite Internet constellation and their integration with existing terrestrial networks, including multiple networking models, a potential benchmarking approach in the laboratory environment, critical configuration parameters, and several suggested test cases. (please see details in: https://datatracker.ietf.org/doc/draft-lai-bmwg-sic-benchmarking/).
 
Any comments, questions, comments are more than welcome!
 
Thanks a lot in advance : )
 
Best regards.
