     62  - Usecase 1: BIER Ethernet in virtualization Data Center
     63     For multicast service in current Data Center, ingress replication using multiple end-to-end IP tunnels is widely used. It is really not an optimal forwarding for multicast packets. Hence, BIER can definitely be introduced in Data Center to provide the optimal multicast forwarding. Furthermore, BIER Ethernet can provide the clean cut design for the underlay ASIC switches. Then the newly designed switches can optimally forward multicast traffic according to the information directly in the BIER header.

     65  - Usecase 2: BIER Ethernet in Service Provider
     66     For multicast service in Service Provider network, it is really tough procedures to explicitly built multicast distribution trees and maintain per-flow state in intermediate routers. Hence, BIER Ethernet, acting as 2.5 multicast solution, can take advantage of underlay network to fulfil multicast service instead of current multicast solution in Service Provider network.

    72 - BIER Deployment Evaluation: [[BR]]
    73   Require a deployment experience draft describing the benefits, problems, and trade-offs for using BIER instead of traditional multicast forwarding mechanisms. Ideally, this should also contain an analysis of the impact and benefit of the new BIER data-plane to the overall Internet architecture.
