Introduction
Short for Simple Network Management Protocol, a set of protocols for managing complex networks. The first versions of SNMP were developed in the early 80s. SNMP works by sending messages, called protocol data units (PDUs), to different parts of a network. SNMP-compliant devices, called agents, store data about themselves in Management Information Bases (MIBs) and return this data to the SNMP requesters.
Each SNMP element manages specific objects with each object having specific characteristics. Each object / characteristic has a unique object identifier (OID) consisting of numbers separated by decimal points (i.e., 1.3.6.1.4.1.2682.1). These object identifiers naturally form a tree as shown below. The MIB associates each OID with a readable label (i.e., dpsRTUAState) and various other parameters related to the object. The MIB then serves as a data dictionary or code book that is used to assemble and interpret SNMP messages.
Short for Management Information Base, a database of objects that can be monitored by a network management system. Both SNMP and RMON use standardized MIB formats that allows any SNMP and RMON tools to monitor any device defined by a MIB.
Development Stage
In developing this Network Management System, we use Visual Basic 6 as our tool. We choose this particular application because it is easier to work with as our entire group member familiar with Visual Basic 6.
First we create interface as input and output data. The interface is important as it is for the user to interact with the system. It give the first impression of the system to the user. Then we copy the MIB from SNMP folder and paste it in the Visual Basic folder. This is for the Visual Basic can detect the MIB. After that we write all the codes to connect MIB tree with Visual Basic. This is the difficult part of the system development. By connecting the MIB tree to the visual basic, the system can display the MIB tree when demand. We use winsock to connect to the network. As the system can connect to the network, it can retrieve data from other host.
How the System Work
This is the initial state of the system. There are just one page of interface with a few textbox. First is the Remote IP address textbox. It is for the user to insert IP address of the host that will be retrieving from. Community Name textbox is for user to select either public, private or secret.
To guarantee that its members receive appropriate, high level quality care in a cost-effective manner, each managed care organization (MCO) tailors its networks according to the characteristics of the providers, consumers, and competitors in a specific market. Other considerations for creating the network are the managed care organization's own goals for quality, accessibility, cost savings, and member satisfaction. Strategic planning for networks is a continuing process. In addition to an initial evaluation of its markets and goals, the managed care organization must periodically reevaluate its target markets and objectives. After reviewing the markets, then the organization must modify its network strategies accordingly to remain competitive in the rapidly changing healthcare industry. Coventry Health Care, Inc and its affiliated companies recognize the importance of developing and managing an adequate network of qualified providers to serve the need of customers and enrolled members (Coventry Health Care Intranet, Creasy and Spath, http://cvtynet/ ). "A central goal of managed care is containing the costs of delivering care, but the wide variety of organizations typically lumped together under the umbrella of managed care pursue this goal using combination of numerous strategies that vary from market to market and from organization to organization" (Baker , 2000, p.2).

Define Protocol: A Protocol is a set of rules or procedures for transmitting data between electronic devices, such as computers. In order for ocmputers toe xchange information, there must be a preexiting agreement as to how the information will be structered and how each side will send and recieve it.
A management information system (MIS) is an information collection and analysis system that facilitates access to program and participant information."(mays.tamu.edu, 2013) This system is usually computerized. Businesses use MIS at all levels of operation to collect, process and store data. Management uses this data in the form of information needed to carry out the daily operations of the business. Everyone who works in business, from someone who pays the bills to the person who makes employment decisions, uses MIS. In fact, many (if not most) companies concentrate on the alignment of MIS with business goals to achieve competitive advantage over other companies. "The major components of the MIS are the database, the model base, and the user interface. The database is used to store important data, the model base has the required statistical models in order to analyze the large amounts of data, and the user interface allows the user of the software to navigate through it and use it with ease."(mays.tamu.edu, 2013)
We are recommending they implement an Enterprise Network Monitoring System (NMS). An NMS system uses This product will monitor SNMP traps from all devices on the network and then report them to a central dashboard. We recommend the company start a Network Operations Center (NOC) that conducts automated monitoring for devices going down and also of any configuration changes to devices on the network. Items marked as ‘high priority’ will automatically be messaged to a small NOC team who will oversee the automated monitoring efforts 24x7. Also, make a policy change that stated any network change that is not management approved will be an unauthorized change to the network and grounds for disciplinary
Service Management- This gives ability to monitor, diagnose and centrally manage the network, using standard based vendor independent implementations. We can get rapid service provisioning with this attribute. It can also be seen as carrier class OAM.
An Open Shortest Path First (OSPF) protocol is the most used interior gateway protocol and computation intensive protocol where energy consumption in Internet Protocol (IP) networks is the main concern. The energy in an IP network can be saved by allowing a subset of IP router interfaces on sleep mode setting during the low traffic hours through the model of “move” by dint of an Energy Aware Routing (EAR) strategy, which is completely compatible with OSPF and is based on the “Shortest Path Tree (SPT) exportation” techinque or “Dijkstra's Algorithm”. In case of heavy traffic hours, the EAR strategy is not usable and may cause denial of service. The strategy implemented can help a network operator to control the network performance and allow a smoothed QoS degradation. This performance evaluation study permits to save about 30% of network links with a insignificant rise of link loads and network path lengths.
Although VPN is very popular in the market for networking technology, it may raise some concerns for IT managers. VPN requires an in-depth understanding of public network security issues and proper deployment precautions. The task of choosing and deploying a VPN solution is far from being simple and may require the training of workers in at least the basics...
Universal Serial Bus is also being used to connect different peripheral devices to your personal computer like the keyboards, printers, digital cameras, media players, internal hard drives and flash drives. It is also the reason it became a standard mode of connectivity. First it was designed just for personal computers but as time passed it has been an option for devices like...

Networks in organisation are dynamic and complex entities which can be quite challenging to configure and manage. (Kim & Feamster 2013). These corporate networks consist of multiple routers, switches, firewalls, middleboxes and a particular advantage of network management is the ability to monitor the entire business network. As all the devices are interconnected with many event occurring simultaneously, problems with once device can eventually lead and spread throughout...
One of the latest advancements in wireless data. It is used in GSM (Global System for Mobile Communications) for transferring data in packets.
Local Area Networks also called LANs have been a major player in industrialization of computers. In the past 20 or so years the worlds industry has be invaded with new computer technology. It has made such an impact on the way we do business that it has become essential with an ever-growing need for improvement. LANs give an employer the ability to share information between computers with a simple relatively inexpensive system of network cards and software. It also lets the user or users share hardware such as Printers and scanners. The speed of access between the computers is lighting fast because the data has a short distance to cover. In most cases a LAN only occupies one or a group of buildings located next to each other. For larger area need there are several other types of networks such as the Internet.
Network management planning and security planning involves identifying the best and most appropriate systems and hardware that the firm can use to better manage network and plan security systems. Therefore, the management required me to examine the best software and hardware systems in the market place that the company can adopt to enable it to manage the network and security. The management required me to advice on the implementation procedure of various plans that are going to be adopted. My responsibility also involved finding out or predicting the impact of the plan on the future operations. They required me to evaluate the challenges the company might face while adopting the changes in the network management plan and security plans.
