Hi David, Thank you very much for your information. We’ve read the document you provided and the application scenarios and solutions are different from the document. The solution here is intent to give a multicast solution, the OAM and the protection functions in the network which only support p2p PW. The solution is different from the solution in BBF document.

I don’t think it proposes to extend the PALS technology. It simply uses PWs to carry L2 (presumably Ethernet) across a provider network, something that PWs already do. Maybe I don’t understand the draft, but this looks like a deployment description that does not need standardisation. Please can the authors help the WG better understand why this needs to be an IETF specification?

Title : Efficient Layer 2 Multicast with Point-to-Point Pseudowires Authors : Weiqiang Cheng Jie Dong Filename : draft-cheng-pals-p2p-pw-multicast-01.txt Pages : 6 Date : 2019-11-18 Abstract: Multicast services such as Evolved Multimedia Broadcast/Multicast Service (eMBMS) become more and more popular in mobile networks. In mobile transport network, it is important for the operators to provide efficient transport of multicast services with existing network devices. This document describes a mechanism of using point- to-point Pseudowires (PW) [RFC3985] to achieve efficient layer 2 multicast transportation in mobile transport networks.The document gives a multicast method by utilizing a Point-to-Point (P2P) path between nodes in a packet transport network , according to the destination IP address. With it, the PTN nodes can replicate and forward the service message, which are received from the multicast server, to the plurality of multicast clients corresponding to the destination IP address.
