Spencer: Thank you for your comments. Perhaps a bit of context will help ---
I2RS WG goal is not to create new protocols, but to re-use and extend existing protocols. This creates a bit if a different flow in the document path. The architecture design allows for multiple protocols (NETCONF, RESTCONF, and others) with multiple encodings (XML, JSON) so that the WG could work through these protocols. However, in any particular version of the protocol will have: a) a set of requirements for features, b) set of valid application protocols (e.g. NETCONF, RESTCONF) with specific features (E.g. ephemeral state, publication/subscription service, traceability, insecure data) c) a set of valid transport protocols (TLS, SSH, HTTP) that transport the application, d) a set of valid protocol security mechanisms, e) recommendations for security environment, and f) data models supported by the protocol. We are currently finalizing the requirements for version 1 with the protocol strawman released this week for extensions to NETCONF/RESTCONF.

One Control and Data Exchange Protocol The I2RS protocol may need to use several underlying transports (TCP, SCTP (stream control transport protocol), DCCP (Datagram Congestion Control Protocol)), with suitable authentication and integrity protection mechanisms. These different transports can support different types of communication (e.g. control, reading, notifications, and information collection) and different sets of data. Whatever transport is used for the data exchange, it must also support suitable congestion control mechanisms. The transports chosen should be operator and implementor friendly to ease adoption. I echo Benoit's question about defining multiple underlying transports. I suspect you'll need to pick one mandatory-to-implement transport protocol, and when everyone has to support that one, I'd be surprised to see implementations that support more than one transport protocol unless the mandatory-to-implement transport protocol is seriously broken in some scenarios. _______________________________________________ i2rs mailing list [email protected] https://www.ietf.org/mailman/listinfo/i2rs
