Hi All, Wanted to clarify the motivation behind Auto-BW draft for stateful PCE. The aim of this extension is to (1) identify the LSP that would like to have this capability along with necessary information like BW range (2) provide current traffic flow information of such LSP to stateful PCE.
We acknowledge that the stateful PCE may use other mechanism outside of PCEP to get this information but also believe that there is an inherent simplicity in doing this as a part of PCEP protocol. Comments and questions are always welcome.
