NBBS network management

Network management for Networking BroadBand Services (NBBS), a general-purpose, multiprotocol, high-speed transport backbone is discussed. The paper begins with the objectives and the key choices made in the development of the network management solution. The managed environment for high-speed transport networks and some features of the NBBS architecture that have influenced the network management solution are described, along with the relationship between the network manager and the managed target system agent, the actual communication environment for the Nways™ Switch Manager. The relationship between the Network Management Workstation and an NBBS node acting as a network management agent is presented. The use of managed object classes to provide a Management Information Base (MIB) that may be accessed by a manager using the Common Management Information Protocol (CMIP) to manage NBBS networks is then discussed. Management application models for accounting, configuration, topology, performance, and fa ult management for NBBS are illustrated, showing how they relate to the NBBS managed objects. The paper concludes with a look at future directions for the NBBS management solution.
