[db-wg] Problem definition for new NWI (12?) - NRTM service

Dear db-wg community,

Please find below the problem definition for the (upcoming) NWI-12 item as we have discussed it and envisioned it for this project. 


Problem definition:

Back on October 2019 during the RIPE 79 meeting in Rotterdam, we discussed about the  need to move forward with a next generation of NRTM service. Upon the completion of NWI-9 and the lifting of the legal restrictions, we can now proceed to design the new solution. As we discussed preciously, the version 3 of the current NRTM solution is not suitable anymore for network operations on 2020. A summary of the reasons are:

-Is a Telnet based protocol, thus:
	• No keep alive mechanism is adopted, 
	• It provides plain text/unencrypted transport of data

-The bootstrap process is not always trivial and sometimes is slow 
-Long time synchronisation is complicated and users need to re-synchronise after a couple of weeks. 
-No well specified protocol (There is just a PDF doc that describes it)

For all the reasons above (and reasons that we might have not think about yet but you are welcome to share), it becomes a necessity for the community to proceed with a new implementation that will be easily adopted by modern tools and last for the years to come. 


I hope the above text is sufficient for the db-wg chairs to kick off the process and the community to share its feedback. 


Best regards,
