vote on naming for Agents types
by Guy Roberts 23 Dec '09

23 Dec '09

Hi All, On the latest NSI conference call we have been pondering a suitable name for the two instances of an Agent that resides on either end of a Network Service Interface. Up to now the term 'Requestor Agent' has been used to identify the agent that originates the connection request, and 'Provider Agent' for the agent that processes (reserves, provisions etc) the request. Objections have been raised to this terminology based on the desire to break away from the old use of 'provider' as used in ISP. We would like to hold a ballot in the NSI group for preferred name. The following names have been suggested, please respond with an email to me with the number of your preferred choice. 1. Requestor Agent, Provider Agent 2. Requestor Agent, Service Agent 3. Requestor Agent, Granter Agent 4. Requestor Agent, Implementer Agent Regards, Guy ------------------------------------------------------------------------------------------------------------------ Guy Roberts, Ph.D Network Engineering & Planning DANTE - www.dante.net<http://www.dante.net/> Tel: +44 (0)1223 371 316 City House, 126-130 Hills Road Cambridge, CB2 1PQ, UK ------------------------------------------------------------------------------------------------------------------

new outline of architecture doc
by John Vollbrecht 19 Dec '09

19 Dec '09

Attached is a revised outline of architecture doc. I list the sections below. The doc has some detail about what might be in each section. Comments are most welcome. Also volunteers to write portions. Thanks for your review. John The idea is to describe step by step pieces of the architecture. Each section (after the first 2) has some implications for the interface that will be included. 1. Abstract and Summary 2. Context and Motivation 3. NS Interface concepts and terminology [define NSI in general and Transport /NSI ] 4. NSI Transport Service Description [define Transport Service offerred over the interface] 5. Transport Service actors [define actor with multiple agents] 6. Interoperating Transport Actors [describe multiple actors] 7. Infrastructures of NS Actors (describe different types of multi- actor infrastructures) Appendix - compare architecture capabilities of existing implementations vs architecture

NSI - Call Issues
by John Vollbrecht 16 Dec '09

16 Dec '09

We will have a call tomorrow at 9ET. I suggest that this be the last call this year and that we restart calls either Jan 6 or Jan 13. We can continue exchanges on skype and by email during this time. I would like to try to have a skeleton document to start discussing by the middle of January and a document for OGF ready by early February. To do this we will have to make some assignments tomorrow or soon after, and probably work in smaller groups to come up with wording. I have two issues that need to be decided for the document. 1) Naming of two sides of NSI interface. We originally named these the requestor agent and network service agent. This after significant discussion, especially about the fact that we should not use provider because it had connotations of the commercial providers. Later we decided to go ahead and use the name provider because Network Service Agent was confusing with other names like Network Service Actor. Also requestor and provider are terms used by others so seemed reasonable. The person who was most strongly against using the name provider was not on the call when we made the decision to change, and he continues to feel strongly that it is a bad name. I think we made a decision not to use provider and should not change it without agreement from the parties involved in the decision. Therefore I would like to change the name of different sides of the NSI to something else. Suggestions are a) requester agent- service agents, b) client agent - server agents. We need to determine the name in order to make the document. I think this is a NSI group decision, and I am hoping we can decide tomorrow. 2) There is an issue with naming end points on the transport resource controlled by an NSA. To explain- A NS Service agent deals with connections between ports. In NML terms the ports are part of a group of connected links and nodes. The edge of the group might be a node or a link. The problem is that in NML terms a link does not have a port. So we need to have a different name for the end points of connections. I think the options are make up a NSI name for the end points, or to have NML define a name. A couple issues with possible solutions. a) If NSI define a name for endpoints then it will have to map back to NML concept for port in case of node and I am not sure what for a link. b) if NML were to say that both links and nodes have ports, then node ports would not be physical, or perhaps they would be defined by a connector at the physical layer. I note that in G.800 both links and nodes have ports, and where ports are connected there is a point. This seems useful when saying that segments are connections between ports and segments are concatenated at points. I am not sure how it fits with other NML concepts. This seems a decision that needs input from NML to decide. Probably this will take some discussion and we may have to have interim names till we decide. -- I would like to talk about these on the call tomorrow. We can continue online if needed. I will send a second email will a proposed outline of a architecture doc and call info. Let me know if you have suggestions for other agenda items. John
