Re: [Pce] Warren Kumari's Discuss on draft-ietf-pce-lsp-setup-type-09: (with DISCUSS)
Hi Warren, Ignas, Sorry for the slow reply. I think Deborah already explained our intent on the telechat. As this document does not actually define any new path setup types (just a mechanism to allow multiple path setup types) we can really only make generalized statements about the sorts of issues that should be considered if a particular new setup type is introduced. We chose to include a list of questions that anyone adding a new path setup type would need to answer. To clarify this intent, I have made the following change. OLD This document generalises PCEP to allow path setup methods other than RSVP-TE to be used by the network. It is possible that, in a given network, multiple path setup methods will be used. It is also possible that not all devices will support the same set of path setup methods. Managing networks that combine multiple path setup methods may therefore raise some challenges from a configuration and observability point of view. Each document that introduces a new path setup type to PCEP must include a manageability section. The manageability section must explain how operators can manage PCEP with the new path setup type. It must address the following questions, which are generally applicable when working with multiple path setup types in PCEP. NEW This document generalises PCEP to allow path setup methods other than RSVP-TE to be used by the network (but does not define any new path setup types, besides RSVP-TE). It is possible that, in a given network, multiple path setup methods will be used. It is also possible that not all devices will support the same set of path setup methods. Managing networks that combine multiple path setup methods may therefore raise some challenges from a configuration and observability point of view. Each document that defines a new Path Setup Type in the Path Setup Type Registry (Section 8.2) must include a manageability section. The manageability section must explain how operators can manage PCEP with the new path setup type. It must address the following questions, which are generally applicable when working with multiple path setup types in PCEP.
