Development of SNMP-XML translator and gateway for XML-based integrated network management

INTERNATIONAL JOURNAL OF NETWORK MANAGEMENT, Issue 4 2003
Jeong-Hyuk Yoon
The research objective of our work is to develop a SNMP MIB to XML translation algorithm and to implement an SNMP-XML gateway using this algorithm. The gateway is used to transfer management information between an XML-based manager and SNMP-based agents. SNMP is widely used for Internet management, but SNMP is insufficient to manage continuously expanding networks because of constraints in scalability and efficiency. XML,based network management architectures are newly proposed as alternatives to SNMP-based network management, but the XML-based Network Management System (XML-based NMS) cannot directly manage legacy SNMP agents. We also implemented an automatic specification translator (SNMP MIB to XML Translator) and an SNMP-XML gateway.,Copyright 2003 John Wiley &Sons, Ltd. [source]


Distributed control of event floods in a large telecom network

INTERNATIONAL JOURNAL OF NETWORK MANAGEMENT, Issue 2 2010
Chundury Jagadish
Events in a failing system can be generated so rapidly that they adversely impact the network as well as the network management system (NMS) manager. They may fail to get delivered and critical information may get lost. This problem becomes worse in a large and congested network. Today, in practice, a management station is often flooded with a huge number of redundant events, making it difficult for the operator to process them and take corrective actions. Methods are needed to limit the volume of event transmission and number of events presented to the operator, while ensuring delivery of important information to the NMS manager. These methods need to take care of the operators' changing needs in monitoring abstraction level, for various network elements (NE) based on time and NE severity state. In this paper we propose novel techniques for distributed control of events flood, by suppressing transient events at the source. These techniques do not add any delay in communicating a failure, while ensuring that only the important events are presented to the operator. Also, the correctness of event state at the NMS is not compromised. Moreover, these methods give flexibility to the operator to dynamically change the abstraction level needed from a network element, and limit the number of events presented to the operator. The implementation of these techniques is tested with real field event traces from various telecom networks. Results show that there is a substantial reduction in the event traffic in the network.

SNMP for home automation

INTERNATIONAL JOURNAL OF NETWORK MANAGEMENT, Issue 4 2004
Ran Giladi
Home and building automation applications impose the need for convergence, or at least interoperability, of data networks with intelligent building networks. This situation entails the use of a unified management system. In this paper we extend the traditional SNMP-based network management system paradigm by creating an integrated site network management system that contains data elements, telecommunication equipment and intelligent building devices. A possible architecture based on a proxy gateway is presented and analyzed. We suggest an implementation and potential applications.,Copyright 2004 John Wiley & Sons, Ltd. [source]


Design and implementation of WAP-based LAN segment management system using RMON MIB

INTERNATIONAL JOURNAL OF NETWORK MANAGEMENT, Issue 3 2003
Jong-Keun Kim
Advances in LAN technology have enabled fast data transmission. However, without effective management of these resources, congestion of networks as well as waste of resources are inevitable. Therefore, it is necessary to supervise, report, and even control, if necessary, the network resource status so that the communication network can be effectively operated without service interruption by monitoring traffic among the hosts. Web-based network management systems have been developed and applied for remote management without using specific applications. However, such web-based network management systems have limited manager mobility and poor performance. To overcome such disadvantages, this paper proposes a network management system using wireless communication. Copyright 2003 John Wiley & Sons, Ltd. [source]


Component architecture in a network management system

BELL LABS TECHNICAL JOURNAL, Issue 3 2003
Neil R. Bass
Component architectures are best known for the benefits of software reuse. However, they are also a basis for creating solutions that can be scaled in both size and feature content. These benefits were the motivation for choosing a component architecture for a large network management system. The architects selected Common Object Request Broker Architecture (CORBA)* and Java* as technologies to implement the architecture and specified a platform to support the components. This paper draws upon the experiences of this system to discuss the structure of such architecture, the implications of the tools and technologies, and the factors important to its success. 2003 Lucent Technologies Inc.
