2. What's the main differences between the solution in this draft and that in Y.1731?
For both one-way and two-way throughput estimation
Binary Search vs. Increase rate with fixed step
OAM msg exchange vs. No OAM msg exchange
Result got At initiator MEP vs. At the remote MEP
For only two-way throughput estimation
Two individual results vs. One minimum result
(No loopback at the remote MEP) (Loopback at the remote MEP)

3. Why the solution in this draft is recommended?
More efficient – In most cases, binary search will take less time than fixed step length
More precise – In most cases, binary search will return more precise result than fixed step length
More convenient – The operator may provision and obtain result at only one MEP
More reasonable – For two-way throughput estimation two individual results return

4. What’s updated in 01 version?
Remove ACH TLVs
Align format of test data packets with data plane loopback draft
Add exception process into the procedures
Add one open issue
