1 Transitions

Rémy

  • Rémy presented the slides on the transition form GTS/WIS to WIS2.0: What, how, who and when: a proposal (to be updated) :

  • Replacing the real time data exchange (the GTS) by the new method (WIS2 messages and download) between members

  • Replacing/updating WIS1 technical solutions

  • Upgrading/replacing Message Switching Systems  in their exchange with local systems

  • Overarching principles of GTS to WIS2 transition

  • role of GISCs in transition to WIS2

  • The transition from WIS1 to WIS2

2 Discussions

ALL

  • Timo> does principle 2 imply that someone operates a gts2wis "gateway"? how otherwise the center that migrated can interact with non-migrated centers without an MSS?

  • Rémy> yes there is a need of gateway GTS2WIS2 and WIS2 to GTS

  • Jeremy> principale 1 means that data are available for wis users and GTS users

  • Rémy> It’s more expressed in principle 3 no GTS data loss during the migration

  • Kai> First we need to have GTS data on WIS2

  • Rémy> Transition can start when GTS data can be received using WIS2

  • Action>> Rémy will update the slides taking into account that

  • Enrico> transition in 2024-2030, how feasible for this period? need KPIs for transitions. One KPI is about the completeness of transition.

  • Podeur> the principle 4 is a key for transition to WIS2. New GBON data will only published on WIS2

  • Rémy>Countries that benefit from SOFF shall switch to WIS2

  • Peter> don’t see any thing about availability

  • Kai> Agree, we need to consider availability. If we start migration and the system is broken, it will be issue for transition

  • Peter> also WIS2 will exchange more larger volume data than GTS

  • We have two things: GTS transition and system related to GTS used at national level. Let’s start by GTS

  • Peter> in Canada we have MSS and we are using also file exchange mechanism, why not using the same for WIS2?

  • Rémy> If we consider the use of MSS in different cases we will never finish with the transition

  • Jeremy> you can provide this service by a local cache for this data

  • Peter> this is what we do, I think it’s not a problem if it’s files or APIs

  • Kai> I want to ask if it is a transition problem.

  • Peter> GTS to WIS2 is easy, what about WIS2 to GTS?

  • Rémy> As we are not talking about the transition and I have something else to do I will stop here

✅ Action items

  • Gateway design to be discussed in another meeting.
