[Nsi-wg] Encoding & Labeltype

[John MacAuley]

You are correct.  This was how Freek also explained it to me.  He also recommended that all Ethernet based SwitchingServices have the same generic Ethernet encoding label.

It looks like we have a bit of an issue then.  If encoding is really the protocol encoding (Ethernet), then we need a label type to identify the label that is switched by the SwitchingService.
