Remote MIB-item look-up service

Despite some deficiencies, the Internet management framework is widely deployed and thousands of management information base (MIB) modules have been defined thus far. These modules are used by implementers of agent software, as well as by managers and management applications, to understand the syntax and semantics of the management information that may be exchanged. At the manager's side, MIB modules are usually stored in separate files, which are maintained by the human manager and read by the management application. Since maintenance of this file repository can be cumbersome, management applications are often confronted with incomplete and outdated information. To solve this "meta-management" problem, this paper discusses the design of a remote look-up service for MIB-item definitions. Such a service facilitates the retrieval of missing MIB module definitions, as well as definitions of individual MIB-items. Initially the service may be provided by a single server, but other servers can be added at later stages to improve performance and prevent copyright problems. It is envisaged that vendors of network equipment will also install servers, to distribute their vendor specific MIB. The paper describes how the service, which is provided on a best effort basis, can be accessed by managers/management applications, and how servers inform each other about the MIB modules they support

MICA: A MID Compiler in Java

Management Information Bases (MIBs) define the attributes of objects managed by the Simple Network Management Protocol (SNMP). An SNMP application uses the information in one or more MIBs to learn the attributes of the objects supported by the managed devices in a network. MIBs in source form are not directly usable; they must first be compiled into a format acceptable to the SNMP application. Java's built-in network facilities make it an ideal language for writing SNMP applications, so the need arises for a Java-based MIB compiler. The MICA project is the design and implementation a Java class library that treats a MIB as an abstract data type (ADT). Java-based SNMP applications use this ADT to compile MIBs and extract their information.http://deepblue.lib.umich.edu/bitstream/2027.42/107925/1/citi-tr-97-1.pd

Penerapan Fault Management Untuk Network Management System (NMS) Berbasis Open Source Pada World Wide InteroperabilityFor Microwave Access (WiMAX)

Network Management System (NMS) is an application that is used to monitor WiMAX Network and Services. The Network Management model that issued by ISO is the main model that consists of 5 (five) concepts: Fault Management, Configuration Management, Accounting Management, Performance Management and Security Management (FCAPS). The function of Fault Management is to detect, record, notify, and possibly to repair faults in order to maintain the effective network. OpenNMS is an open source NMS application which can be modified to be a Fault Management application which is a standard for WiMAX network. The WiMAX network monitoring is simulated with Net-SNMP using the OID from MIB IEEE 802.16f. The result suggests OpenNMS is applicable to manage faults.

Formal Specification and Testing of a Management Architecture

The importance of network and distributed systems management to supply and maintain services required by users has led to a demand for management facilities. Open network management is assisted by representing the system resources to be managed as objects, and providing standard services and protocols for interrogating and manipulating these objects. This paper examines the application of formal description techniques to the specification of managed objects by presenting a case study in the specification and testing of a management architecture. We describe a formal specification of a management architecture suitable for scheduling and distributing services across nodes in a distributed system. In addition, we show how formal specifications can be used to generate conformance tests for the management architecture

A management architecture for active networks

In this paper we present an architecture for network and applications management, which is based on the Active Networks paradigm and shows the advantages of network programmability. The stimulus to develop this architecture arises from an actual need to manage a cluster of active nodes, where it is often required to redeploy network assets and modify nodes connectivity. In our architecture, a remote front-end of the managing entity allows the operator to design new network topologies, to check the status of the nodes and to configure them. Moreover, the proposed framework allows to explore an active network, to monitor the active applications, to query each node and to install programmable traps. In order to take advantage of the Active Networks technology, we introduce active SNMP-like MIBs and agents, which are dynamic and programmable. The programmable management agents make tracing distributed applications a feasible task. We propose a general framework that can inter-operate with any active execution environment. In this framework, both the manager and the monitor front-ends communicate with an active node (the Active Network Access Point) through the XML language. A gateway service performs the translation of the queries from XML to an active packet language and injects the code in the network. We demonstrate the implementation of an active network gateway for PLAN (Packet Language for Active Networks) in a forty active nodes testbed. Finally, we discuss an application of the active management architecture to detect the causes of network failures by tracing network events in time

Inventory Collection System Pada Sebuah Local Area Network Dengan Memanfaatkan Java Management Extensions

Inventory Collection System (ICS) is an application, that has a function to collect and save hardware and software data from computer hosts that connected to a network. In this research ICS application on netword based on Transport Control Protocol/Internet Protocol (TCP/IP) made by exploit on Management Information Base (MIB) on Simple Network Management Protocol (SNMP). Access of objects are in MIB designed use one componen from the Java, i.e. Java Management Extensions(JMXTM). Inventory data samples taken from some terminals showed in this research
