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.
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.
The output information that each function has can vary. The same information can be output to several different things that either the Commander can use or the Soldier can use. All of the information that this system inputs goes into a big database that can be accessed by another information system outside of eMILPO. This system is a very powerful system and can be used for several different purposes. Like I said earlier this system combines 43 different Information Systems into one powerful system that allows the Army to update and maintain a Soldiers record from one application or system.
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)
MAC Layer Connections: Management connections and data transport connections are two connections in this layer. The management connections have three types: basic, primary, and secondary. A basic connection and primary connection are created for each MS when they join the network. A basic connection is used for short and urgent management message. And a primary connection is used for delay-tolerant management messages. The secondary connection is used for IP summarized management messages such as dynamic host configuration protocol [DHCP], and simple network management protocol [SNMP]. Transport connections can be provisioned or can be recognized on demand. They are used for user traffic flows. Unicast or multicast can be used for transmission.
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.
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...
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
Network Design is very important when it comes to implementing a connection between a computer and a server. According to Network world Websites, Network is defined as a “connected collection or devices and end systems, such as computers and servers, that can communicate with each other”(McQuerry). Network carry data in many types of environment, such as homes, small businesses, and large enterprises. Network Locations Is one of the major factors. There are different types and locations of network exist, including network in a home or home office to communicate through the Internet, to locate information, to place orders for merchandise, and to send message to friends. Whatever the reasons are, all these networks share common components. According to Network World, the most common network components are Personal Computer’s, interconnections, such as NICs, Networks media, and Connectors. Switches and Routers are also part of network components. When designing a network, couples of items are a must to have such fundamental goals, a drawing or diagram, The Hierarchical Network Design, IP addresses, routing protocols, Servers, and switches.
The network databases operations are usually through navigation, i.e. the program maintains the current position and moves from one record to another by following the defined relationship upon which the record is involved. Records can also be located by providing key values.

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...
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.
One of the latest advancements in wireless data. It is used in GSM (Global System for Mobile Communications) for transferring data in packets.
