...Walter White Blank University NETW420 Professor Teague Week 7 paper 4/22/13 There are many metrics used in network management that can be broke down into three sections including classic, cost, and revenue for short. The classic metrics consist of availability which is the percentage of time during which a service is functioning properly. Availability is broken into two aspects, as a whole and availability that factors maintenance, where maintenance is more effective because it only captures unavailability caused by a negative surprise. MTBF or Mean Time Between Failures is a measure of reliability its job is to give an indication of how often a service or device becomes unavailable, but not so much the length of the outage. MTTR also known as Mean Time To Repair provides the length of time it takes for services that are impacted by failures to be restored. Total cost of operations can be normalized over a different group of metrics, such as, the number of devices and the operational cost per device. Devices and differ in nature and scale so this metric is not always meaningful unless dealing with homogeneous environments. The number of ports is another metric that provides a more level playing field and allows operational cost to be compared across different types of equipment. An example of number of service instances could be the operational cost per voice extension. The number of end users would be the operational cost per employee in an enterprise. There are...

...Running head: FCAPS FCAPS DeVry University NETW420 John Tang Jan 25, 2014 In this week’s Assignment, I am going to briefly explain and describe the five network management categories that make up the FCAPS. They all have an important role and figure within the network management team, and they all know what to do and what their job description is based on the problem that happens and occurs within the company. FCAPS is a network management framework created by the International Organization for Standardization (ISO). The five network management categories within the FCAPS are: * Fault Management * Configuration Management * Accounting (Administration) * Performance Management * Security Management They all have an important role within the company that they must do, and they all get paid differently based on what they are doing, some of them it can be a job promotion over time, for some of them it can be a demotion. But it all depends on the company. Most companies like to pay all of their workers the same based on their knowledge and skills, and their work performance, or then their job description. At the fault management level, network problems are found and corrected. Potential future problems are identified and steps are taken to prevent them from occurring or recurring. With fault management, the network stays operational, and downtime is minimized. Define thresholds for potential failure conditions. Properly implemented, fault management...

...08 Fall SOLARWINDS: NETWORK MANAGEMENT SYSTEM VALENTINO ALAN LLEREZA De Vry UNIVERSITY In today’s world, the growth of computer technology has impacted and enhanced the way we communicate with each other and even the way we live. Many companies use this technology to create some type of computer network to be able to get information to and from each other during an ordinary day. As the computer network grows, the requirement for a network administrator increased. The network administrator is tasked with the management and responsibility of keeping the network healthy, at all times. This is accomplished through managing the activities, methods, procedures, and tools that pertain to the operation, administration, maintenance, and provisioning of networked systems(Clemm, 2007). To assist the network administrator, the use of network management system such as the Solarwinds Network Management System helps reduce operational cost while offering a secure and stable network that is crucial to all businesses. It does matter whether you’re a huge corporation or a small business, many computer network issues are unavoidable. The use of Solarwinds Network Management System presents various applications to maintain the simplicity of network management and is the complete package. The management software makes it easy to discover and map network devices, monitor network performance, analyze network traffic, manage and back up network configurations, track IP addresses...

...Basic Components of Network Management Systems Matthew D. Miller DeVry University A network management system is a system that is made up of hardware and software, whose job it is to manage the communications, software, and computer hardware of a network (Hill Associates, 2008). There are many different tools and components that help to make up a network management system. Some of these tools include trouble ticket systems, help desk systems, alarm correlation, maintenance tools, etc (Hill Associates, 2008). Along with all these tools there are four basic components that a network management system consists of. They are the agent, network management station, network management protocol, and the management information (Hill Associates, 2008). As mentioned before a network management system has many tools available to use. Trouble ticket systems are used to manage and keep track of any and all issues relating to the network (OTRS Team, 2012). A very useful feature of trouble ticket systems is that they save and archive the tickets with all pertinent information like who was involved, the problem and any notes or solutions (OTRS Team, 2012). In case a particular event occurs again the help desk team has a reference to look to for assistance. With any kind of machine or system, maintenance must take place in order for it to perform to its full potential. Software and hardware updates are essential for the smooth running of a network (TWD & Associates, Inc., 2012)...

...Cisco Network Management System NETW-420 Enterprise Network Mgmt Professor Introduction Cisco uses the International Organization for Standardization network management model which defines five functional areas of Network management. The model consists of Fault Management, Configuration Management, Performance Management, Security Management, and Accounting Management. In this paper we will cover the models five functional areas. Fault Management Fault management detects, logs, notifies users of, and tries to automatically fix network problems to keep the network running effectively. Fault management is perhaps the most widely implemented of the ISO network management elements. The reason is because faults can cause downtime or unacceptable network degradation. Fault Management uses a network management platform deployed in an enterprise infrastructure that consists of multivendor network elements. Network management platforms can be viewed as the main console for network operations in detecting faults in the infrastructure. The platform receives and processes events from network elements in the network. Events from servers and other critical resources can also be forwarded to a management platform. A standard management platform consists of Network discovery, Topology mapping of network elements, Event handler, and Performance data collector and graphed. Configuration Management Configuration management monitors network and system configuration...

...Network Management Systems Doniel Lovely NetW420: Enterprise Network Management Professor: Winston Park Devry University Date: 6/23/2013 Effectiveness and efficiency can at the same time or simultaneously perform at high standards in any given business organization. While effectiveness refers to the levels at which any organization realizes its goals through managing to accomplish set tasks, efficiency is highly related to the magnitude of resources utilized to achieve these goals of the organization. (Daft and Lane, 2008) This is a report set to answer the question, “Which are the various metrics used to measure the effectiveness and efficiency of a network in pursuit of organizational goals?” The report will answer in a detailed manner this aforementioned question. In PERT, the requirement is that each activity should be provided with three kinds of estimates. These are: Optimistic, Pessimistic and most likely times. Under the PERT procedure, the optimistic time denotes the shortest duration an activity can take to complete (pert.com, 2013). Commonly, to determine the Optimistic time three standard deviations are utilized to reduce the level of error in calculating the times. Pessimistic time on the other hand is the longest duration an activity may take to finish. Also, here three standard deviations are applied from the expected time. The Most likely time is the highest probability that an activity will be through in a given set time. However, this is not the same...
