Network Design: Physical and Logical Design Essay

From 2004 to 2008 a mission begins to aggressively develop within the intelligence community that will change the face of the Department of Defense (DoD). Cyberspace Operations, particularly support to, breaks from small organizations and gains light in every day missions as well as the media. Complexity and connections of Cyberspace Operations makes this mission inherently a joint responsibility from training to execution. In the beginning the Army evaluated soldiers from all Military Occupational Specialties (MOS) and selected those that showed the capability to grasp complex problems and adapt to new technologies in order to staff this mission. These highly skilled soldiers received special training

The first topology represented is the Ring topology. A ring topology is a network in which all traffic moves in only one direction because of this the speed is faster than some other topologies, even as network traffic increases. Due to the configuration of a ring topology the resources of the network are available to every device and the cost of setup can be lower than some of the more complicated topologies. However, the configuration of the Ring topology is also a disadvantage. Since a file sent to any device within the network has to pass through every device, if one device fails the entire network goes down. (Ethernetpedia)

3. NETWORK (layer 3) – Provides switching and routing technologies, creating logical paths, known as virtual circuits, for transmitting data from node to node.

Taking this class I have learned good amount of terms we use in IT sector. From ch1 and 2 have help me allot more in depth about its technology and mostly understanding how each things work and the pros and cons about security and what are useful gadgets to have. Topology was the term I wasn’t familiar with but the concept was always around me weather at school library or labs and at work place. There is physical and logical topology, physical topology we use at home and mostly see in various work station in our life time. It mostly hardware and how the end devices interconnect. When two computers connect directly with one another without a central device, with a wires it be called physical topology. Logical topology is software and does contrast with physical side but logical define

Simply put, a topology is that the layout of a network. There are extremely 3 basic kinds of topologies. they're Star, Bus, and Ring. Let me justify them to you.

Mission: As a member of the land war net team we are the main support for any TDY mission concerning the 106th Signal Brigade Network Enterprise Center and the security or of network. You are expected to be mission ready and take on the task of learning at all times. When a mission arises you will have your DTS prepped and finalized once the final details come down. You will have your military travel card ready and active in case a unexpected mission comes down. When TDY you will be at your place of duty on time and conduct yourself as a professional.

The current network is a fairly early design called an Ethernet Bus network. A bus network Topology is an architecture in which a set of clients are connected via a shared communications line, called a bus. Each of the 3 sites utilizes the same configuration of

On 22 January 2013, General Martin Dempsey, Chairman of the Joint Chiefs of Staff released a white paper describing his vision for the Joint Information Environment (JIE) and how it would support operations in the years to come.1 This mandated transition is driving a reassessment of the most appropriate command and control (C2) structure to conduct operations within the domain. Attempts to achieve a standardized fully interoperable environment will only achieve limited success due to the innate variability and changing nature of technology, exacerbated by service unique capabilities and requirements as well as inconsistent funding. Existing C2 models either fail to address the uniqueness of operations in the cyber domain or otherwise fail to

In order to provide speed and reliability, large and enterprise-level networks today are typically constructed in multiple layers. They are the access layer, also called the network edge layer, the aggregation or distribution layer; and the network core layer. The access layer is usually a mesh of network switches, linked to other switches in the aggregation layer, which in turn is linked to the core.

Between the time initial MRAP tests were conducted and the initial approval in 2006, the military was transitioning away from the original Requirements Generation System (RGS) to the current JCIDS. Requirements from the field through each service branch drove the RGS process resulting in standalone solutions to specific threats often not considering non-material alternatives. “JCIDS provides systematic, integrated and interoperable material and non-material solutions to capability needs.” JCIDS determines requirements from the top and develops joint solutions with long term sustainment plans. The JROC is the final approving authority within JCIDS before passing the requirement to the acquisition process. During this transition the JROC membership remained unchanged but they did change from last to first approving authority in the major defense acquisition program process. This

The mission of JTF-N is to “provide military support to law enforcement agencies, conduct theater security cooperation…facilitate interagency synchronization...in order to anticipate, detect,

Fortunately, the U.S. Army, in conjunction with the Department of Defense, have devised plans to ensure the United States’ leadership role is unchallenged. When implemented the Joint Information Environment will be able to support combatant commanders, with the ability access relevant information quickly, through a shared infrastructure which host integrated application systems (Joint Chief of Staff, 2013). The ability to share data across

For example, the ring and bus topologies are very inefficient with the way traffic travels throughout the network are difficult to implement on a large scale

You are the network manager of a company that has grown from 10 employees to 100 employees in 12 months. Year 2 projected growth is estimated to be 100 additional employees located at a remote location. The aggressive growth has brought about some unique challenges and opportunities. The company has one remote warehouse and no off-site disaster recovery services or servers. The network design remains a non-redundant, flat topology.

All the computers, in the logically and physically networks have to follow the same rules known as Protocols such as TCP/IP, IPX/SPX and NETBEUI etc. Today, there are many computer networking technologies such as LAN, MAN, WAN, WLAN, ISDN, ATM, Frame Relay, X.25, Bluetooth,
