Network Management Protocols and Tools Study


Book Description

Seminar paper from the year 2000 in the subject Computer Science - Technical Computer Science, grade: 1,7 (A-), UNITEC New Zealand (Information Systems), course: Course Enterprise Networks and Management, language: English, abstract: The report covers the evaluation of the network management protocols SNMP (Simple Network Management Protocol) and CMIP (Common Management Information Protocol). The history of the network management protocol is explained in the beginning to set the base for an understanding of the need for efficient network management protocols, which carry management information in their payload. The description and thorough comparison of the two protocols reveal several highlights: SNMP and CMIP are designed with different backgrounds and purposes. SNMP is appreciated due to its simplicity and ease of implementation and criticized for its lack of security issues and overall performance. CMIP was designed to overcome the shortcomings of SNMP and to outweigh it in every field. This aim has been achieved but what renders the protocol useless is the fact that it requires too much network resources. SNMP remains the network management protocol of choice. After the presentation of the two protocols the attention is drawn to the impact of middleware on the management processes. Middleware can be considered as a layer of software that supports multiple communication protocols, multiple programming languages, and runs on various computer platforms. It helps to integrate otherwise incompatible system components by providing standardized mechanisms that distributed components can use to communicate over a network. With middleware the best of both worlds (SNMP versus CMIP) can be achieved. The most important middleware technologies are the Distributed Component Object Model (DCOM) and the Common Object Request Broker Architecture (CORBA). Although middleware eats up network resources significantly, it adds value to the corporative network due to its high performance and standardized interfaces that enable managers to employ network devices with the focus on the gained benefit rather than on their potential integration in the current network environment. One can see that network management, supported by middleware, moves towards the coverage of all layers in the OSI reference model.




Essential SNMP


Book Description

Simple Network Management Protocol (SNMP) provides a "simple" set of operations that allows you to more easily monitor and manage network devices like routers, switches, servers, printers, and more. The information you can monitor with SNMP is wide-ranging--from standard items, like the amount of traffic flowing into an interface, to far more esoteric items, like the air temperature inside a router. In spite of its name, though, SNMP is not especially simple to learn. O'Reilly has answered the call for help with a practical introduction that shows how to install, configure, and manage SNMP. Written for network and system administrators, the book introduces the basics of SNMP and then offers a technical background on how to use it effectively. Essential SNMP explores both commercial and open source packages, and elements like OIDs, MIBs, community strings, and traps are covered in depth. The book contains five new chapters and various updates throughout. Other new topics include: Expanded coverage of SNMPv1, SNMPv2, and SNMPv3 Expanded coverage of SNMPc The concepts behind network management and change management RRDTool and Cricket The use of scripts for a variety of tasks How Java can be used to create SNMP applications Net-SNMP's Perl module The bulk of the book is devoted to discussing, with real examples, how to use SNMP for system and network administration tasks. Administrators will come away with ideas for writing scripts to help them manage their networks, create managed objects, and extend the operation of SNMP agents. Once demystified, SNMP is much more accessible. If you're looking for a way to more easily manage your network, look no further than Essential SNMP, 2nd Edition.

Web-based Network Device Monitoring Tool Using Simple Network Management Protocol (SNMP)


Book Description

The Internet enables different computer networks to join together into one network in which many different models of network devices can co-exist with each other. Standard management protocol is necessary for the purpose of managing these networks. SNMP (Simple Network Management Protocol), one of the standard protocols, is designed for this open"'flass management function and is successfully implemented. This thesis suggests a monitoring of network device statistical data from a remote place. This approach reduced the complexity of existing techniques, which are basically operable in specific operating system and having no standard Graphical User Interface (GUI). To address this problem, a system based on WWW standard tool is developed which is SNMP compatible as well as operable with any network device. The network device monitoring tool is a client program, which is managed and could be contacted with the server program. A web server and a browser are to provide static, dynamic, and interactive management information. A web server, which plays a managing role, offers a variety of types of information. An SNMP agent, which co- operates with a web server, uses SNMP protocol and provides access to management information of network devices/agents. The implementation of the user interface using the web-based technique of Java Applet makes it possible for a manager to easily search and manage agent Management Information Base (MIB) through a browser. Java SNMP class files and SNMP Applet Server (SAS) classes are used inside the Web-server to communicate with network devices. The network device monitoring tool is configured to collect network statistical data. It can monitor the real time graph on the basis of MID variable from remote place and shows more efficient than the existing tool.
