Re: [PWE3] Poll for WG adoption of draft-shen-pwe3-endpoint-fast-protection-04

[Mingui Zhang <[e-mail]>]

Hi, 

I have read the draft and have the following comments and questions. 

1. When I read the ICCP draft and RFC 6718, I thought PW-RED offered the mechanism for PE and AC protection. Is there any difference between the solution here and the PW-RED?
 
2. Whether providers need manually configure the protector?

3. There seems no detail for the proxy method to be followed by the implementers. Add a reference here or elaborate it?

4. I am glad to see there is some text talking about the " Revertive Behavior ". I was designing a protection mechanism before, knowing that this is not an easy problem to be solved. If the PLR revert to the new primary PW ahead of time (before the convergence). Loops or packet loss may happen. I remember I was asked by the question: how does the PLR determine the time to revertive? Timers are what I can think of. I wonder whether there is any better idea. 

5. A minor issue. What is "control plane repair"? See para3 of the introduction. I think both global repair and local repair involves both data plane and control plane behaviors. 

If I missed anything, please correct me.

Thanks,
Mingui
