Hi all, I am Quan Xiong , a newcomer for IETF. I have submitted a draft about BIER-TE forwarding in cooperation with Yongqing Zhu and Huannan Chen. We mainly focused on the assignment of BitPositions and the configuration of BIFT.The controller MAY compute the explicit paths from BFIR to each BFER first and then assign the BitPositions including SD, BSL and SI combination to the adjacencies per flow instead of tracking the topology to determine the BitPositions. This document also proposes a merthord for the assignment of BitPosition to adjacencies and defines two types of the assignment policy of BitPositions. If the multicast flow needs to be sent from a BFIR to M BFERs along M explicit paths, the controller host MAY assign BitPositions for all adjacencies of M explicit paths with the K sets of SD, BSL and SI combinations which K and M is set according to the assignment policy. EXCLUSIVE-TYPE: Each multicast flow MAY use one or more SD, BSL and SI combination exclusively. SHARING-TYPE: More than one multicast flows MAY share the same SD,BSL and SI combination. Please check the draft for details as following shown. https://datatracker.ietf.org/doc/draft-zcxh-bier-te-forwarding/ Comments are welcome! Thank you!
