Academic literature on the topic 'SNMP Management'

This research focuses on developing a secure, SNMP-based network management system specifically tailored for deployment in internetworks that rely on low-bandwidth backbone networks. The network management system developed uses a two-level hierarchy of network management applications consisting of one top-level management application communicating with several mid-level management applications strategically distributed throughout the internetwork. Mid-level management applications conduct routine monitoring chores on behalf of the top-level management application and report results in a way that makes intelligent use of the limited bandwidth available on the backbone network. The security framework is based on using SNMPv2c over IPSec. This research shows that the other security alternative considered, SNMPv3, consumes as much as 24 percent more network capacity than SNMPv2c over IPSec. The management framework is based on the Management by Delegation (MbD) model and is implemented using the IETF DISMAN Script MIB. This research demonstrates that the MbD-based management framework consumes only 2 percent of the network capacity required by the traditional, centralized management scheme.<br>Master of Science

The content of this thesis is to research possibilities of using SNMP for management of Mobile IP activated entities. The first two chapters deal with theoretical analysis of Mobile IP protocol, and Simple Network Management Protocol. The Mobile IP protocol analysis focuses especially on the elements Home agent and Foreign agent. In the SNMP chapter the analysis focuses mainly on ways to exchange messages. Another part of the document is devoted to a description of laboratory networks com- posed of routers Cisco 1841 and the configuration of them. Finally is described the programmed application to manager these devices in JAVA, which is included in Annex. The program periodically sends SNMP queries and finds relationships between the Home agent and the mobile nodes, and between the foreign agent and the mobile nodes. The application has a user-friendly interface that is shown on the attached flash animation. Finally, the thesis summarizes the concepts described in previous chapters and the goals to achieve.

As System Management provides the capability for dynamic allocation of resources, it is critical to support the level of network flexibility envisioned by the integrated Network-Enhanced Telemetry (iNET) project. This paper investigates the practical performance of managing the Telemetry Network System (TmNS) using the Simple Network Management Protocol (SNMP). It discusses the impacts and benefits of System Management as the size of the TmNS scales from small to large and as distributed and centralized management styles are applied. To support dynamic network states, it is necessary to be able to both collect the current status of the network and command (or modify the configuration of) the network. The management data needs to travel both ways over the telemetry link (in limited bandwidth) without interfering with critical data streams. It is important that the TmNS's status is collected in a timely manner so that the engineers are aware of any equipment failures or other problems; it is also imperative that System Management does not adversely affect the real-time delivery of data. This paper discusses measurements of SNMP traffic under various loading conditions. Statistics considered will include the performance of SNMP commands, queries, and events under various test article and telemetry network loads and the bandwidth consumed by SNMP commands, queries, and events under various conditions (e.g., pre-configuration, normal operation, and device error).

nÃo hÃ<br>Devido ao crescente uso de computadores e a forte dependÃncia dos mesmos em vÃrias aplicaÃÃes, as UPS (Uninterruptible Power Supplies) vÃm adquirindo cada vez mais importÃncia. Estes dispositivos encontram-se muitas vezes dentro de um contexto de um sistema distribuÃdo, o que fortalece a necessidade de gerenciamento dos mesmos. Devido à grande utilizaÃÃo das UPS em computadores, e devido ao fato destes, por sua vez, estarem inseridos em um ambiente de redes TCP/IP, torna-se bastante viÃvel a idÃia de se usar um sistema de gerenciamento que seja compatÃvel com esse ambiente, e que faÃa uso de suas potencialidades. No presente trabalho à apresentado a implementaÃÃo de um sistema de gerenciamento SNMP (Simple Network Management Protocol) para UPS que possibilita o gerenciamento de um nÃmero arbitrÃrio de UPS, e que permite a autenticaÃÃo remota para gerentes, facilitando o uso para um maior nÃmero de dispositivos. Detalha-se a implementaÃÃo do sistema bem como os testes realizados. No final do trabalho à apresentada uma proposta para trabalhos futuros na Ãrea.<br>The reliability of a computer system is based not only on the computer itself, but also on its related power system. For that reason, more and more critical systems are counting on UPSs (Uninterruptible Power Supplies) to account for a continuous supply of power. Although the task of managing an UPS for a standalone system be quite straightforward, when it comes to computer distributed systems that task has to follow an equally distributed approach. Depending on the strategy used to manage that distributed UPS network, this task may be very complex. However, keeping in mind that most computer systems in a distributed architecture make use of TCP/IP to be logically connected, one could profit from the facilities provided by this protocol and design a management strategy that makes use of it. In fact, TCP/IP is not the only suite of protocols used to interconnect computer systems. SNMP (Single Network Management Protocol) is also frequently used as a way of managing (hardware and/or software) devices associated with computers. This dissertation proposes and implements a way of managing distributed UPSs by using SNMP, taking advantage of all the facilities furnished by the protocol. This works describes how the use of SNMP makes it possible to manage an arbitrarily number of UPSs remotely. This makes the design of UPS management systems a relatively easy task, and contributes to introduce a high degree of flexibility on the task of managing distributed UPSs. Finally, it is described how the system and tests were implemented as well as proposals for future work is presented.

This work outlines ways of getting dynamic state into OMNeT++ model. SNMP as major technology was selected for reaching the goals. Protocols CDP and LLDP are participating in topology detection and in theoretical layer Breadth- first search is used. The output of this tool is file syntactically specied by NED language which is describing computer network.

The purpose of the Walkstation II project is to create a testbed for a wireless communication system with access to the Internet. The Mobile INTernet (MINT) router is a core element of this project. Most of the routers and many other nodes of today's Internet support network management. This includes the remote control of various parameters which caracterize the status of physical interfaces, protocols and many other objects. The Simple Network Management Protocol (SNMP) which was used in the current work is a standard protocol of the TCP/IP suite. All the managed nodes of the Internet have a common set of management capabilities. Their implementation is available in software development packages. The management of mobile stations requires a new set of management capabilities. They will allow for the control of mobility support and the radio links. The current work consists in adapting the set of standard SNMP capabilities to the MINT router and of the creation of a set of new capabilities specific to the MINT.<br><p>I do not know the number of university credits, but entered it as 30 ECTS.

Communication between various broadcast equipment plays a major role in the daily operation of a typical broadcast facility. For example, editing equipment must interface with tape machines, production switchers must interface with font generators and video effect equipment, and satellite ground controllers must interface with satellite dishes and receivers. Communication between these devices may be a simple hardware handshake configuration or a more elaborate software based communications via serial or parallel interfacing. This thesis concerns itself with the software interfacing needed to allow various dissimilar types of equipment to communicate, and therefore, interface with each other. The use of Simple Network Management Protocol (SNMP) in a non-typical manner for the purpose of hardware interfacing is the basis for this work.
