Does the aim mean the draft describes the problem space and standardize the way for the centralized solution or mean the draft will standardize the way used for both the centralized solutions and the distributed solutions?

It does not standardize any algorithms. For a centralized algorithm (unspecified) use one has to distribute the flooding topology it does specify this. It also supplies the means to signal what distributed algorithm is in use (a value).

> 2. I explained in the previous mail the distributed solution includes more than the algorithms defined in the draft-cc-lsr-flooding-reduction-00  and the overlapped signallings  defined in the draft-cc-lsr-flooding-reduction-00/draft-li-dynamic-flooding-03. For example, it may define the standardized procedures for the distributed solutions. If there is such part, is it defined by draft-li-lsr-dynamic-flooding-02 or draft-cc-lsr-flooding-reduction?

How a distributed algorithm decides to implement itself is up to that algorithm. This is not part of the signaled information. Again, the only thing that I am aware of in draft-li-dynamic-flooding in regards to distributed algorithms is what's required for us to use them as they get defined in the future, i.e., a way to signal which one is in use.

Thanks,
Chris.

The intent after adoption of draft-li-lsr-dynamic-flooding-02 is two-fold. One, the WG can discuss adding any signaling ideas from this work to the adopted signaling draft (with proper attribution given as appropriate), and two, for the authors of draft-cc-lsr-flooding-reduction-01 to publish a new document without the signaling portion and instead focus on their flooding topology algorithm. This new focused document can be considered in parallel along with the other algorithm work that has been proposed.
