Hi, Dhruv:

We will update the deployment consideration section continuously in the following stages. 
And we can also keep in mind that the existing mechanisms described in RFCs about PCE and their application in MPLS network can be reused in the application of PCE in native IP network.

Adding the central control to the existing network is the trend of network evolution. CCDR solution described in this document can improve the E2E performance of native IP network that controlled by one administrator, and reuse the capabilities of existing deployed network devices in large extend. 

Thanks again for your comments and suggestions on this draft. We can discuss more on the protocol extension draft later.


Best Regards

Aijun Wang
