Hi all,

Some notes from the meeting today.

We had a short discussion about the IP/MPLS (TE) L3VPN use case. The detailed information provided by Stephen need to be further explained/discussed at our next meeting.
We agreed with the conclusion that TE information in L1 microwave topology is not necessary for the proper functioning of a PCE, but we also need to consider other aspects before we decide how to proceed.

  *   We need to understand and draw conclusions also from the remaining two use cases
  *   Other drafts augmenting te-topology (e.g. MPLS-TP, OTN and WSON) are network technologies in that sense that paths/tunnels can be created using links and connectivity matrices from within that single te-topology. Microwave is not a network topology in that sense. It is only a “link-by-link topology” since paths/tunnels can only be created on higher layer topologies, e.g. TDM and Ethernet. How should this affect the choice of basis for a microwave topology model?
  *   How to take care of future use cases that might require te-information? Does it really impact the choice today?
  *   …


Next meeting is planned for Thursday January 9, 11-12 CET.

Merry Christmas & Happy New Year.
