A couple additional notes from the call this morning We had a lot of discussion about parameters and the difference between abstract and technology specific parameters. We had a list of parameters in the issues doc, and Guy will edit these into the strawman doc. Discussion about the parameters - abstract parameters seem to imply a range - e.g. a 100mb depends on what exactly what technology and network are used, whereas a 10GE interface is specific about what is provided at least at the interface - Tomohiro made the distinction between quality parameters for the connection as a whole and parameters at the edge point. Edge point parameters are things like VLAN or slot numbers, quality parameters are things like jitter or drops. Edge parameters are required, some quality parameters are optional (some may be required). --- We talked about whether Waves and fiber bundles were alternative connection topologies. We had discussion about whether waves were appropriate as raw input or if waves always started as bits. If waves start as bits, then it seems to me there is an adaptation to carry them on waves, but the underlying "type" of connection is bits. Joe pointed out that waves were being switched in labs and that standards should handle the future where possible. Also fiber bundles are less problematic and can be switched, and their characteristics are not bits. So a question I have is whether NSI should be interested in data (bits) connections or also in generic connections like waves or fiber bundles. This is to be determined - I would be interested in comments. There is also a need to describe L3 and perhaps L4 connections if we want to do that. It might be possible to say these are possible but concentrate on L2 for first pass of the document. --- A discussion about different services that are used by and perhaps provide by a NS included the suggestion by Chin (which seems right to me) that Topology sharing be described basically for inter NS but allow it to be used by others. I think the intent is that we should include this as needed to support inter NS capability and assume that will be sufficient for other users. --\ Please comment or add to any of these - John
