Standards development within the Information Technology sector is harmonized with international standards development. Through the CSA Technical Committee on Information Technology (TCIT), Canadians serve as the Canadian Advisory Committee (CAC) on ISO/IEC Joint Technical Committee 1 on Information Technology (ISO/IEC JTC1) for the Standards Council of Canada (SCC), the ISO member body for Canada and sponsor of the Canadian National Committee of the IEC. Also, as a member of the International Telecommunication Union (ITU), Canada participates in the International Telegraph and Telephone Consultative Committee (ITU-T).
This Standard has been formally approved, without modification, by these Committees and has been approved as a National Standard of Canada by the Standards Council of Canada.
This part of ISO/IEC 16500 describes the management architecture and protocol for managing the DAVIC System. The DAVIC system management architecture is the TMN-based (Telecommunication Management Network) architecture defined in ITU-T Recommendation M.3010. This management architecture allows for automatic administration, configuration, monitoring, billing, and maintenance of the Service Provider System, the Delivery System, and the Consumer System over the DAVIC S5 flows. In accordance with DAVIC 1.3.1a Part 4 and ISO/IEC 16500-5, the content of these flows is based on either the CMIP protocol or the SNMP protocol, depending on the complexity of the underlying subsystem or the preference of the network provider. SNMP MIBs (Management Information Base) for managing the STU and the Server have been defined in ISO/IEC 16500-5. Usage related information models have also been defined in ISO/IEC 16500-9 using both CMISE and SNMP. For managing the ATM, SDH/SONET components of the Core Network of the DAVIC Delivery System, CMISE models defined in ITU-T and ATM Forum are recommended in ISO/IEC 16500-5 subclause 10.5.3. Taking into account that the current DAVIC specification for the Access Network is ATM-based 1, this Part of ISO/IEC 16500 defines CMISE information models for managing the DAVIC Access Network and service related data in the Delivery System. In the future, if DAVIC specifications allow alternative access technologies (such as IP-based), additional system management information models (such as SNMP MIB) may be needed. The management of the coexistence of different access network technologies, using different protocols, could be achieved through interworking tools (i.e., interworking between CMIP and SNMP) as described in subclause 6.4.
Tutorial information on a protocol-independent modeling technique is also provided in an informative annex.
