[Planetlab-devel] opening up GetSliceTicket()

[Stephen Soltesz]

Hey, David,

I have questions just for clarification.

What distinguishes a slice that is called 'delegated' from a slice that is 
called 'plc-instantiated'?  Is the difference just 'slices NM will look at' 
vs 'slices NM will not'?  You say that a ticket doesn't 'allow the bearer to 
do anything they couldn't otherwise do.' I understand this as: in both cases 
there is existing mechanism for instantiating the slice regardless of how 
the slice info gets to NM.

If there is more to delegation than this, I want to find out more. If this 
is the essential distinction, then 'delegated' or 'PLC instantiated' is just 
another slice attribute, right?  Is it treated differently than this today?

Does anyone with history have insight into whether anyone complained about 
slices.xml (public slice info)?

Thank you,
Stephen.
