I would also like to add a signalling/control plane topology discussion to the list. i have a slide package we can use to discuss the topic of finding a messaging path for your reservation request. John. On 2012-02-20, at 4:28 AM, Guy Roberts wrote:

Several topics I'd like to see on the agenda for V2: --- Related to control plane topology is _topology distribution in general_. Given that some agents will not have a NSI trust relation with others, how do we envision NSAs learning topology? IMO, need to me up with some basic NSI requirements/objectives, and then a reasonable general approach (details can be worked out later). This is important in that it will have a bearing on what local domains will be responsible for managing. The topology management task in general needs to be delegated to the domains themselves - the sooner the better as we will see more early adopters over coming 12 months. --- I would also like to broach the issue of _uni-directional connections_ and how we might approach these and the issue of _point-to-multipoint connections_ in V2. --- We have discussed the STP naming extensions, which addresses some issues in enumeration of STPs and SDPs. But we have not worked through the _"any point" specification/semantics in the ReservationRequest primitive_. Relaxing the single point constraint on the end points is key to resolving some of the exhaustive search issues when hunting for intermediate transit points. --- I think we need a better and more _generally applicable solution to the NAT problem_. Fundamentally, the NSI high level protocol should be able to send messages back and forth to recognized NSAs at will, regardless of their NAT situation. If a RA NSA can send an unsolicited NSI message to a PA NSA, then the PA should be able to do likewise to the RA NSA. The NAT issue affects messaging both ways and should not be an NSI concern. I think there are ways to address this situation that may not need NSI protocol machinations - and may not require MTL special handling either. Maybe this is part of the UNI discussion? Thanks!

Hi Guy, I would like to open a discussion in Oxford on adding an optional constraints field that can be used for prototyping extensions while still being compatible with the "base" CS protocol. For example, if the base CS protocol only supports point-to-point services and we wanted to prototype a point-to-multipoint service, we can use the optional constraints field to carry this information. It can be useful to explore other services such as anycast/multicast/manycast, protection/recovery to name a few. NSAs that are not interested in the prototyping activity can simply treat the field as opaque. If folks are interested in discussing this, I can plan to come up with a few slides presenting the idea and some cautionary. Thanks. - Chin On 2/20/12 1:28 AM, Guy Roberts wrote:
