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

Off-topic, Inder Monga wrote: > Are B1, B2 or the dark colored circles the external interfaces aka the STPs? What's an STP? :) I made a few circles red and green. I specifically did not name them. Personally, I think about red as "end point" and green as "network edge", but I did not want (or dare to) touch upon issues as if the green dot in A connecting to B is the same green dot in B connecting to A, and if network C should announce any dots in the first place (being a link without active network equipment, but with a policy; I thought of it as a transcontinental link). Also, in network virtualisation, what once was a network edge is no longer an edge in the virtualised domain. Should I still make it a green dot or not? I just picked one choice, hoping no one would ask. :) Feel free to supply your own names. STP is as good as any other name. Regards, Freek

service instance and temporal aspects of services
by Tomohiro Kudoh 21 Jun '10

21 Jun '10

Hi all, I could not hear the later part of the previous session clearly, so maybe I miss the point, but: - if request path is hierarchical, service instances also have hierarchical relationship. That is, a service instance is created for each provider along the path. - temporal aspects may exist not only for the connection service but also for other (to be defined) services. Tomohiro

by Guy Roberts 21 Jun '10

21 Jun '10

Hello All, This is a reminder that we have 3 NSI meetings scheduled for this Sunday at OGF29. As discussed on the calls, we will be collecting all NSI group internal comments and these will be considered at the meetings. I would encourage anyone that has comments and is not attending in person to send these comments to the list by Sunday morning. These will then be included in our review process. Once the review comments have been incorporated, the NSI architecture will then be formally submitted as a draft informational document. You can see the latest version of the NSI architecture document here: http://forge.gridforum.org/sf/go/doc15984?nav=1 The meeting agenda is as follows: Session 1: Review of section 1: Context and Overview Review of section 2 NSI architecture Session 2: Review of section 3: The NSI protocol. Review of section 4: Representing network architectures Session 3: Review of section 5: The NSI services Also, please let me know if you would like to participate in an NSI-WG dinner and I will make arrangements. I look forward to seeing you in Chicago. Guy
