Hi, I have three basic questions (but I might the correct place in RFCs or drafts for that...); 1. How does the protocol for computing a single path works in a hierarchical network (more than one level of PCE's)? 2. What the draft for the concurrent optimization referred to: only inside of a sub-domain or also an inter-domain optimization which requires communication between the PCE's? 3. Can we assume that the node's demands are splittable (i.e., can be simultaneously satisfied by more than one path)? Many thanks, David Amzallag BT
