Network Management System Essay Example for Free

Network Management System Essay A Network Management System is a combination of software and hardware which is used for monitoring and effective administration of a network. For any network which requires management of number of network tasks to be integrated in a single software solution, there is a need of effective and efficient planning. It is the task of the network management system to locate network support, keep a check on the activities and health of the network devices attached and provides exceptional handling mechanism in order to alert the administrator in cases of conditions which can hinder the performance of the network(Laudon Laudon,2007). NMS systems use many different kinds of protocols in accordance their usage for example one of the commonly used is SNMP protocol which allows the gathering of information to be simplified for the administrator and users over the network from the devices attached in accordance to the network hierarchy. The NMS software are responsible for problem identification along with the exact source of the problem and provide effective solutions in order to prevent the problem from effecting the performance of the network. The NMS are also responsible for collecting the device data and numbers in terms of statistics to keep a log of the performance of the network. This usually includes a library of protocols which help the administrator in the management of the network through the Network Management System software. For to make sure there is a streamlined management of the network, every network is assigned a network manager. The network manager is responsible for monitoring the activities, methods which help the network running which includes the procedures which are usually defined for every specific network and lastly, the use of tools which the network administrator/manager is well equipped with in order to control monitor and use in terms of exceptional handling over the network. The operation of the network manager is to deal with keeping the network up and running smoothly. This includes the task of finding out any problem and rectifying it in time to make sure all systems over the particular network are not affected by the downtime of the network. Maintenance of the network involves proper measures and preventive procedures and measures for the network to be running smoothly such as the task of adjusting device configuration parameters for systems on the network(Laudon Laudon,2007). A management information base (MIB) is defined as a virtual database which is used for management of the network activities over a communication network. They are often related with the SNMP protocol commonly known as Simple Network Management Protocol. it is commonly used to pass on to a meticulous subset, more appropriately referred to as MIB-module. Items in the MIB are distinct by means of a subset of Abstract Syntax Notation One (ASN. 1) also known as Structure of Management Information Version 2 (SMIv2) RFC 2578 which performs the parsing for the MIB compiler on the network. The Remote Network Monitoring (RMON) for MIB was developed to sustain supervision and protocol scrutiny of the local area network. The unique versions centers on OSI Layer 1 and Layer 2 in sequence in Ethernet and Token Ring system. It is unmitigated by RMON2 which appends maintenance for the Network Layer and Application Layer monitoring and by SMON which has added support for switched networks. Probing helps the system to examine and evaluate the network consistently and thus, helps the network manager to keep the network agents in check and up and running. â€Å"The following diagram shows a reference architecture that Cisco Systems believes should be the minimal solution for managing a data network.

Report on copper ‘Copper is a commodity that measures the pulse of the global economy’ (Tutor2u, 2012). The features of this metal is the reason why it is demanded so highly around the world, which is the reason why â€Å"copper is the third most widely used metal in the world† (investopedia, 2013). What makes Copper so different from other metals? Firstly, pure copper is ductile which means it can easily be stretched and shaped into different forms. Secondly, the scientific elements of copper make it highly conductive in heat and electricity than any other metal, except silver which is 100 times more expensive. Thirdly, it is 100% recyclable. Did you know 80% of copper ever mined is still in use today? Fourthly, it is highly alloyable. Lastly, it is one of three metals that has its own unique colour other than silver or grey. In the current market copper is used in a variety of ways due to its specification. 5% of copper production is used in combining with other metals to form a lloys such as brass and bronze. 15% is used in industrial machinery, because coppers superior conductivity improves the electrical energy efficiency of motor-driven systems. 20% is used in roofing and plumbing because the lifespan of copper is estimated to be 100 years before major defects in the material start to occur. Lastly, the remaining 60% of copper is used in electrical wires and the reason why such a huge proportion is used in electrical wires is because there are no close substitutes for copper. Aluminium wiring is comparably priced, but is unsafe and can start fires and silver is a slightly better conductor of electricity; however it is too expensive (visual capitalist, 2013). In this report I will cover the supply and demand of copper and how it a... ...e amounts of copper (oracle mining, 2013). Copper is an example of a good that has low price elasticity of demand, which means that a change in price would lead smaller change in demand. The reason for this is because there is a lack of close substitutes in the market. For some products that use copper components can be substituted for aluminium or plastic; however, the costs and delays involved in switching between substitute goods aren’t worth it sometimes (copper investing news). Copper is used in a variety of different ways in some uses it would be a necessity an in others it would be a luxury. For example in some plumbing cases you would be able to use flexible plastic pipes, which is cheaper to use, however if you choose not to then copper would be deemed an luxury product. On the other hand, in some plumbing cases you have no choice but to use copper pipes.
