Enabling OSI CMISE via X/Open management APIs

This paper describes the development of an industry-standard Application Programming Interface (API) which provides access to the Open Systems Interconnection (OSI) Common Management Information Service Element (CMISE). The management API solution that has been defined by X/Open® and the results of the API experimental prototype effort performed at Bell Communications Research (Bellcore) is presented. This paper is based on and extends from a paper that was submitted to Globecom '92 [1].

CMISE functions and services

The common management information service element (CMISE), an application service element (ASE) developed to support the management application of the Open Systems Interconnection (OSI) applications layer, is discussed. It was developed in response to the need to monitor and control the health of OSI communications entities. Similarly, the simple network management protocol (SNMP) was developed in the Internet community to manage network resources. Although CMISE was developed to manage resources such as OSI protocol entities, its applicability in managing the telecommunication network elements has been accepted in CCITT and ANSI T1 standards because of its powerful features.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

SONET and OSI: making a connection

The application of open system interconnection (OSI) protocol and management principles to synchronous optical network (SONET) operations and management is described. The role of the seven-layer OSI protocol stack in allowing SONET network elements to communicate with each other and with operation systems (OSs) by way of SONET data communications channels, local area networks (LANs), and wide-area packet-switched networks is discussed. The use of object-oriented information modeling techniques and the services of the common management information service element (CMISE) for developing standardized operations messages are described. The transition from the current operations communications environment supported by many OSs to the fully OSI-based target environment is briefly discussed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
