1. Summary of the SMIng WG The Next Generation Structure of Management Information

2. Purpose of this WG Provide an improved data definition language for the IETF Encourage convergence of data definition and modeling in the IETF

3. WG Charter (summary) Reusable components Protocol independent (merge SMIv2 & SPPI DDL) The language will also provide: syntax optimized for parseability, human readability, & 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

4. Protocol Independence Achieved via adding a level of indirection High-level definition of type definitions, data structures & their relationships Low-level mappings to SNMP/COPS tables & OID assignments SNMP MappingCOPS Mapping

5. Proposed Syntax Formal ABNF Extensible Structured data Easy reuse of data via containment Allow for derivations of type definitions and data structures class InetFilter : Filter { attribute InetSubnet srcSubNet { description "The subnet to match against."; }; attribute InetSubnet dstSubNet { description "The subnet to match against."; }; attribute InetPortRange srcPortRange { description "The port range to match against." }; attribute InetPortRange dstPortRange { description "The port range..."; }; attribute InetProtocolNumber protocol { access readwrite; description "The protocol number to match."; }; description "This class represents a generic IP filter. };

6. Status Requirements document is currently being completed SMIng language proposal has been submitted to the WG Core modules documents submitted Mapping documents to SNMP & COPS submitted Interim meeting this week
