Minutes of TICTOC conference call  22 Feb 2011–03–01

The call started at 14:10 UTC and ended at 17:55. The audio was not as good as it had been on previous calls, with frequent echo and background noise.
Attendees included Karen (moderator), Yaakov, Sebastien, Laurent, Manav, Ron, Michel Ouellette, Peter Meyer, Tim Frost, Xialiang, Stefano, Silvana, Shahram (who came on only for the last few minutes). Those present at the Q13/15 ITU meeting were gathered in Room H2 in the Montbrillant building.

The call once again focused on the MPLS encapsulation issue. Yaakov reviewed the background of the encapsulation options, contrasting the 1588-specific approach with the generic MPLS approach. Manav added that the control plane work could be done in such a way as to satisfy both approaches. No-one had serious objections to the proposal that we start by advancing the 1588-specific draft, and that later the generic method could be advanced.

Sebastien brought up the issue discussed at length in the previous calls of whether an MPLS encapsulation is needed for 1588. In his opinion service providers would not trust an MPLS layer solution, since between MPLS equipments may be Ethernet devices that would not understand the new encapsulation, and would thus break any end-to-end TC or BC. On the other hand, hop-by-hop Ethernet was universally applicable. Yaakov reiterated that there may be service providers that do not have access to layers lower than the MPLS, and that the lower layers were not necessarily Ethernet.

Karen stated that TICTOC would be meeting in Prague, and that before then we hoped to have a security expert, with whom we were speaking, sign on as editor of a TICTOC security draft. Silvana asked if she should respin the TICTOC requirements draft that was long expired, and Karen suggested that the two of them speak about this off-line.
