Hi Manav et al, In speaking with Stefano last week, it seems if the mapping is PTP over IP over MPLS, or PTP over Ethernet over MPLS then we may be able to re-use the existing IEEE 1588 Annexes for IPv4 and Ethernet mappings. This may save some time to develop this IETF specification.

For example, the protocol address used for the portAddress. The Annex D - F seem to have generally the same structure. Annex E Transport of PTP over UDP over IPv4 D.1 General D.2 UDP port numbers D.3 IPv4 multicast addresses D.4 transportSpecific field values D.5 Optional values D.6 IPv4 Options D.7 Protocol addresses Annex E Transport of PTP over UDP over IPv6 E.1 General E.2 UDP port numbers E.3 IPv6 multicast addresses E.4 transportSpecific field values E.5 Optional values E.6 Protocol addresses Annex F Transport of PTP over IEEE 802.3/Ethernet F.1 General F.2 Ethertype F.3 Multicast MAC Addresses F.4 transportSpecific field values F.5 Optional values F.6 Protocol addresses Microsemi Corporation Peter Meyer Timing & Synchronization Communication and Medical Products Group Office: +1-613-270-7203 | Fax: +1-613-592-1010 [email protected] | www.zarlink.com "Bhatia, Manav (Manav)" <[email protected]> Sent by: <[email protected]> 07/10/2011 01:48 AM To "[email protected]" <[email protected]> cc Subject [TICTOC] FW: I-D Action: draft-ietf-tictoc-1588overmpls-02.txt Hi Tictocers, This version incorporates whatever comments we had recived till date.

This draft is a work item of the Timing over IP Connection and Transfer of Clock Working Group of the IETF. Title : Transporting PTP messages (1588) over MPLS Networks Author(s) : Shahram Davari Amit Oren Manav Bhatia Peter Roberts Laurent Montini Filename : draft-ietf-tictoc-1588overmpls-02.txt Pages : 34 Date : 2011-10-06 This document defines the method for transporting PTP messages (PDUs) over an MPLS network. The method allows for the easy identification of these PDUs at the port level to allow for port level processing of these PDUs in both LERs and LSRs. The basic idea is to transport PTP messages inside dedicated MPLS LSPs. These LSPs only carry PTP messages and possibly Control and Management packets, but they do not carry customer traffic. Two methods for transporting 1588 over MPLS are defined. The first method is to transport PTP messages directly over the dedicated MPLS LSP via UDP/IP encapsulation, which is suitable for IP/MPLS networks. The second method is to transport PTP messages inside a PW via Ethernet encapsulation, which is more suitable for MPLS-TP networks.
