proposal for revised figures in Network Services Framework document
by Guy Roberts 09 Jul '10

09 Jul '10

Attached are 3 proposed re-workings of figures 5 and 9 for the Network Services Framework document. Figure 5 has been split into 2 diagrams 5a and 5b. Figure 5a identifies the Service Plane and explains its relationship to the existing well known management, control and transport planes. It also introduces the different types of network modelling used on each plane. It also shows which parts are in-scope and which are out-of-scope for the NSF. Figure 5b shows the way that this model is intended to be used to manage Connections. Figure 9 shows a more detail on the representation of networks, in particular how STPs connect Networks. Any feedback is appreciated. Guy

comments on NS Framework 0.3
by John Vollbrecht 07 Jul '10

07 Jul '10

Sorry not to get these sooner, but we have had a holiday and I have had trouble finding time to go through it. I attach a copy with tracking on, that includes edits and comments. In general I think it is getting better - Some overall comments - I think the format of the document is getting better and simpler. The wording in most places is good, with some edits in the doc. There are a few conceptual questionss that I have still -- 1. We agreed to define network and network service. I don't see that, or at least not a clear definition. Is that to be added? 2. I assume some stuff will be incorporated in the Connection Service Architecture -- is that still right? 3. The concept of STP as described is not consistent between sections. I believe that we agreed that an STP is a point in a transport net which can be connected to another STP in the same net by an NSA. I believe we agreed to use the INJ concept for the connection between STPs in different transport networks. This seems to have reverted to the STP and INJ being the same thing, with no entity that describes the edge of a network at a physical (resource) level. -- John

Topology virtualisation
by Freek Dijkstra 30 Jun '10

30 Jun '10

Attached is a picture (and source) that I've just shown at the NML group. It simply shows a few networks, the representation and delegation (virtualisation) of the network. Feel free to use it to show a few of the issues that are associated with control, topology description, topology aggregation, and delegation. Regards, Freek
