Next Generation Structure of Management WG (sming) Wednesday, December 13 at 1530-1730 Thursday, December 14 at 0900-1130 =================================== CHAIR: David Durham Mailing List: General Discussion: sming@ops.ietf.org DESCRIPTION: This working group shall develop a standards-track specification for the next generation data definition language for specifying network management data. As a starting point, the WG will use the SMIng language developed in the IRTF Network Management Research Group. SMIng represents a superset of the SMIv2 (Structure of Management Information v2) and the SPPI (Structure of Policy Provisioning Information). The objective is to replace both the SMIv2 and the SPPI with a single, merged language as the data definition language for the monitoring, configuration, and provisioning of network devices. The language developed will enable the modeling of network management information in a manner that provides the benefits of object-oriented design. To achieve this, the language must allow the design of highly reusable syntactic/semantic components (templates) that can be reused by multiple IETF working groups for convenience, consistency, and to maximize interoperability in device management. A registration mechanism will also be described for reusable components defined using the language so that their existence and purpose may be archived. The language will provide for the definition of a transport-independent model so as to allow a variety of implementation-specific technologies to be derived from a single definition. To demonstrate this, the working group will define two technology specific transport mappings: one for SNMP, and one for COPS. The language will also provide: - syntax optimized for parseability, human readability, and non-redundancy - conventions for representing inheritance and containment of defined data - enhanced attribute-level and association-level constraints - a maximal amount of machine-parseable syntax so that programmatic tools can aid in modeling and implementation - a language extension capability This working group will also define typical usage scenarios for the language and highlight its features. Finally, it will develop a framework by which reusable components specified using this language can be registered and made readily available for continued reuse and improvement. The working group will not define models for specific technologies, except as required for illustrative examples. Specific models are to be developed by the subject matter experts using the SMIng in the appropriate technology specific WGs. AGENDA: * First Session, WEDNESDAY, December 13, 2000: - Review of agenda (5 mins) - Introduction of WG (chair, 15 mins) - documents - milestones - Vision of SMIng (Juergen Schoenwaelder, 20 mins) - Review of preliminary requirements (Andrea Westerinen, 20 mins) - Overview of the SMIng language features given requirements (Juergen Schoenwaelder, 30 mins) * Second Session, THURSDAY, December 14, 2000: - SMIng Language presentation: specifics & examples (Keith McCloghrie & Juergen Schoenwaelder, 60 mins) - General discussion from the floor (30 mins) - Open issues (Juergen Schoenwaelder, 30 mins) - Call for document contributors given charter goals (chair, 20 mins) - Wrap-up (10 mins) Documents for discussion: - SMIng - Next Generation Structure of Management Information http://www.ietf.org/internet-drafts/draft-irtf-nmrg-sming-04.txt This memo presents an object-oriented data definition language for the specification of various kinds of management information. It is independent of management protocols and applications. Protocol mappings are defined as extensions to this language in separate memos. The language builds on experiences gained with the SMIv2 and its derivate SPPI. It is expected that the language presented in this memo along with its protocol mappings will replace the SMIv2 and the SPPI in the long term. - SMIng Core Modules http://www.ietf.org/internet-drafts/draft-irtf-nmrg-sming-modules-01.txt This memo presents an SMIng module that introduces core data types such as counters, date and time related types, and various string types. These definitions build on RFC 2578 and RFC 2579. - SMIng Internet Core Modules http://www.ietf.org/internet-drafts/draft-irtf-nmrg-sming-inet-modules-01.txt This memo presents SMIng modules that introduce commonly used Internet Protocol specific data definitions. They are provided so that other SMIng modules that would otherwise define their own representations can import them from a common place. - SMIng Mappings to SNMP http://www.ietf.org/internet-drafts/draft-irtf-nmrg-sming-snmp-01.txt This memo presents an SMIng language extension that supports the mapping of SMIng definitions of identities, classes, and their attributes and events to dedicated definitions of nodes, scalar objects, tables and columnar objects, and notifications for application in the SNMP management framework.
