FW: submission for NSI arch
by Guy Roberts 31 Mar '10

31 Mar '10

Hello all, Please find attached submission on NSI inter-network topology model from John Vollbrecht. Guy -----Original Message----- From: John Vollbrecht [mailto:jrv@internet2.edu] Sent: 30 March 2010 17:52 To: Guy Roberts; Jerry Sobieski; Tomohiro Kudoh; Joan Antoni Garcia Espin Cc: John Vollbrecht Subject: submission for NSI arch Guy and all -- This took longer than I had hoped to finish. Please distribute it to the NSI group as a whole if you think it appropriate. I include Joan on this because I think (hope) he will be interested in the authorization/topology issues in section 2- especially since he has volunteered to do something with the concept of "owning". Attached is a submission for NSI protocol spec. I am not sure how it fits with what exists now, but I think it could be in a introduction or overview section. A couple notes - I did not use the term STP. I tried, but it didn't seem to fit, and I still have a problem with understanding its precise definition in different circumstances. This can be changed once we sort this out. I tried to separate the part that deals with multi-NSA infrastructures from the basic interface description. I think this works, but maybe not. I added some description of the interaction between NSA authorization and transport topology. I hope this is a good start and can be useful in separating discussions of topology and authorization which probably should happen in a limited way before releasing the recommendation I included some high level description of paths. I think (hope) this is good intro to some of the stuff Jerry has written. As a interesting note, in the path discussion it describes path as Path == [ingress (-egress, ingress)* - egress] It is interesting to note that the term (-egress, ingress) might be considered a Point or edge (or even a link) between networks I am most interested in reactions and comments. Thanks John

Definition of Owner
by Freek Dijkstra 16 Mar '10

16 Mar '10

Hi, We had a short discussion on the term "ownership" today. In 2006, a few colleagues (Bas van Oudenaarde and Leon Gommans) and I had the same problem and read a few standards (TMN one of them as I recall), and came up with these definitions. This was published in 2007, http://staff.science.uva.nl/~fdijkstr/publications/controlmodels.pdf ================================================================ Owner, Administrator and Users. We distinguish between legal owner, economic owner, administrator and user(s) for each network element. The legal owner of a network element is the entity that purchased the device and the economic owner is the entity that acquired the usage rights from the legal owner. We base these terms on current practice in economic and legal communities. The economic owner determines the policy of the network element. This entity carries the responsibility for the behavior of a device and has the final responsibility in case of hazards and abuse. In addition, each network element can also have a separate administrator, the person, organization, or software component that configures and administers the device on behalf of the economic owner. The economic owner determines the policy for a network element; the administrator enforces this policy. Finally, the users may use or invoke an element, if their request is in compliance with the active policy. ================================================================ The only thing I would change todays is to avoid the word "administrator" due to its ambiguity and use the word "operator" instead (which in fact was in an earlier draft of this paper). Regards, Freek
