Hi all,

I think that protection-switching is one of the most important services in transport networks.
So, I suggest that it should be included in the framework.
I add three protocols related to the service: protection-switching request, response, and failure event.
Please, see attached the two files.

Specially, I want Daniele and Young to check the violet colored line modified by me in <.ppt file>.
The line indicates a control channel connecting between PNC3 and EP3's node.
It is used to configure the head-end and tail-end for protection-switching.
It will be great if you give me some clear description about  the solid lines between PNC and network infra(each domain).
(Some nodes are not connected to PNCs)

Sincerely yours,
