Here I have a question about section "5.5 Management-Based PCE Usage".NMS as the PCC sends service request to PCE and gets the response,then supplies the head-end LSR with computed path.why not PCE sends the response with service request direct to the head-end?
Because the architecture defines the interaction between a PCC and a PCE and in this case the NMS acts as a PCC. If A asks a question to B, B may answer to C but the dialogue may quickly be confusing.
Thanks.
JP. AS it just looks like the figure as below: -----------
| ----- |
Service | | TED |<-+----------->
Request | ----- | TED synchronization
| | | | mechanism (for example,
v | | | routing protocol)
------------- | v |
| | Request | ----- |
| NMS |---------+> | PCE | |
| | | ----- |
------------- -----------
Service |Response
Request |
v
---------- Signaling -----------
| Head-End | Protocol | Adjacent |
| Node |<--------->| Node |
---------- ----------- If so ,we can reduce the complication and burden of NMS,and increase the efficiency (NMS don't need to transfer respone between PCE and head-end). Regards, Mach Chen Huawei Technologies, Beijing,China
