Hi, I am proposing a BoF (will find BoF co-chair TBD) to do work on NETCONF Data Modeling (NDM WG). DOCUMENTS: http://www.ietf.org/internet-drafts/draft-bierman-ncx-smi-00.txt MAILING LIST: Send comments on this BoF proposal to the NETCONF GOES ON (NGO) list: mailto:ngo@ietf.org PURPOSE: The NETCONF protocol needs a standard content layer. A data modeling framework is needed which supports ongoing development of WG and vendor defined modules, within an integrated and seamless conceptual configuration database. It is important to determine if and how standard NETCONF data model modules with writable configuration data, compatible with the <edit-config> operation, can be developed in the IETF in a manner similar to MIB module development. There are many different viewpoints on NETCONF and its non-existent data model. Hopefully, consensus could be reached anyway, based on real use cases and running code. In the area of network device configuration, the IETF has rarely been able to achieve any deployment success. So far, NETCONF is no exception. SMIv2 (for SNMP) provides many features that the IETF relies on to maintain an integrated and ever-changing mix of vendor and standard MIB modules. There are many features unrelated to the SYNTAX or DESCRIPTION clauses, such as object and instance naming, module headers, definition importing, INDEX and MAX-ACCESS clauses, version control, and flexible agent conformance, which NETCONF does not currently address. A NETCONF compatible data modeling framework is needed, which provides these important features. It is important to distinguish between XML usage conventions for better interoperability and NM usability, and data modeling languages. By focusing on the XML instance documents themselves (i.e., NETCONF PDUs), an SMI can be developed which can be supported by many languages. However, for better interoperability, a canonical mapping for all NDM constructs to the XML Schema Definition (XSD) data modeling language is needed. NDM WG OUTPUT: The output of the NDM WG would be 1 or more documents defining the structure of NETCONF data models, focusing on the common mechanisms needed to develop standard and vendor defined data model modules. This work can (and should) be done concurrently with actual configuration data model development, such as the data model to configure partial locking. It would be useful for a separate WG to focus on the larger issues for an entire management system, and develop the conventions and mechanisms needed for standard data models to follow. NDM NON-GOALS: The NDM WG will not produce any new data modeling language. Instead, existing mechanisms such as Xpath will be used instead. The NDM WG will not integrate multiple data modeling architectures into some sort of unified XML melting pot. Future work on specific protocol integration support, such as SNMP/SMIv2, would be possible, once the output of the NDM WG was published. _______________________________________________ NGO mailing list NGO@ietf.org https://www1.ietf.org/mailman/listinfo/ngo
