All,

For those of you that joined yesterday’s GNA-G community VC 1ahttps://www.gna-g.net/attend-a-meeting/gna-g-community-vcs-q1a-2023/, you have seen my presentation for the new GREN Engineering Advancement workgroup (if you want you can download them from https://filesender.surf.nl/?s=download&token=651fac23-a738-456e-81f2-a6b... link valid till march 9th, afterwards if they are unavailable on the GNA-G website drop me an e-mail).

The aim of this workgroup pioneer, try, test, experiment with solutions to better/more efficiently/redundantly run services over links part of the GNA-G. We have been doing vlan engineering for ever and know the downsides of it. On the other hand, almost all of us run a MPLS enabled network that provides far more protection/redundancy/fast failover. What can we do to also bring this into the world of GNA-G and the links with which we interconnect NREN’s? This workgroup wants to inventorize what possibilities are out there and test them. This knowledge will be distributes to the relevant engineering groups running systems like ANA-Engineering or AER-Engineering. Who on there turn can provide feedback for additional testing or ideally decide to implement it.

The goal of this workgroup is therefor strictly focussed how can we enhance operation on systems between production networks. So no very experimental stuff like thing that could be considered in the Data Intensive Science workgroup as prototyping and pre-production.

Over the past months I’ve reached out to the ANA partners at Nordunet 2022, SuperComputing 2022 and Internet2 TechEX 2022 and noticed a lot of enthusiasm and interest in this subject. With this I want to call for engineers interested in participating in this workgroup. Folks that have ideas and can contribute in testing them. You can sign up to the mailing list at https://lists.gna-g.net/postorius/lists/gren-engineering-wg.lists.gna-g.net/. From there we’ll start planning for an initial call to kick things of.

Attached the draft 0.9 charter of this workgroup
