I understand it is related to slicing but didn't get it fully - Amina: Dealing with resource allocation and placement. Main proposal is using DRL algorithm, that separates the domain. How each domain allocates the ressources separately. Control by heuristics, to optimize the orchestration the placement of network slices. DRL agents in each domain and central agent to allow gaining an end-to-end view. Automated feature extraction from the infrastructure, and it learn how to orchestrate. 19:30 Concepts of Digital Twin Network, Diego Lopez https://datatracker.ietf.org/doc/draft-zhou-nmrg-digitaltwin-network-concepts/ - Laurent: The content of the presentation is on the draft or a it is a list of challenges? - Diego: We would like to see collaborations. Considering the draft, there are some guidelines, but we are not able to meet all until now. - Jérôme: - Diego: This should be one of the goals of the digital twins. Specially, the idea of injecting some traffic and control conditions that mimic the real behavior of real users. We try to in some cases to predict, lets say, running 25 networks and see what happens. - Jérôme: Is is possible to predict using inputs as maximum and minimum? - Diego: Once you are able to mimic, we will be able to identify patterns. - Franco: We have a similar concept, we are interest to see how we can frame this and talk more about it - Diego: It would be nice, we would like to talk to people that work closely to ours. - Franco: More related to network security. 20:00 End Participants: 1.
