1 University of Twente The Netherlands Centre for Telematics and Information Technology Background of SMIng Aiko Pras CTIT University of Twente the Netherlands

2 University of Twente The Netherlands Centre for Telematics and Information Technology HISTORY OF SMIng DEVELOPED BY IRTF-NMRG SNMP over TCP SNMP compression SNMP GetSubTree XML DTD for SNMP MIBs SMIng

3 University of Twente The Netherlands Centre for Telematics and Information Technology WHY DID WE START SMIng? SMIv2 RELIED ON 1988 VERSION OF ASN.1 TOOLS FOR SMIv2 RELATIVELY COMPLEX CERTAIN DATA TYPES WERE MISSING IN SMIv2 64 bit integers, … LIMITED FACILITIES TO REUSE DEFINITIONS SMIv2 DID NOT ALLOW FOR EXTENSIONS NEW, POSSIBLY INCOMPATIBLE VARIANTS APPEARED THE CHALLANGE: CREATE A COMMON DATA DEFINITION LANGUAGE, INDEPENDENT OF SPECIFIC PROTOCOLS

4 University of Twente The Netherlands Centre for Telematics and Information Technology DATA VERSUS INFORMATION MODEL Informal / english,... “formal” / UML,... MIBs SMIv2 PIBs SPPI DATA MODEL INFORMATION MODEL Conceptual model / abstract model LDAP SCHEMA CORBA IDL

5 University of Twente The Netherlands Centre for Telematics and Information Technology DATA MODEL & “TRANSFER” PROTOCOL MIBs SMIv2 LDAP SCHEMA CORBA IDL PIBs SPPI LDAPv3 SNMP - BER COPS - BER DATA MODEL “TRANSFER” PROTOCOL INFORMATION MODEL

6 University of Twente The Netherlands Centre for Telematics and Information Technology ROLE OF SMIng MIBs / PIBs LDAP SCHEMA CORBA IDL SNMP - BER COPS - BER SMIng INFORMATION MODEL DATA MODEL

7 University of Twente The Netherlands Centre for Telematics and Information Technology SNMP - BER SMIng PROTOCOL MAPPINGS COPS - BER INFORMATION MODEL SNMP MAPPING COPS-PR MAPPING MIBs / PIBs SMIng
