Assignment 2: Network Topology Design 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. Your assignment must

Outline the three general network topologies (bus‚ ring‚ and star). Describe the components‚ devices‚ and arrangement of components and devices involved in each topology‚ as well as some of the pros and cons of each configuration. A bus network topology has the set up in which all the devices are connected by a common shared cable called the bus. The bus architecture has several common instances which include the one in the motherboard‚ (of most computers) and some with the versions of the Ethernet

Introduction Network architecture is a combination of topology and protocols. In this paper‚ I will discuss topology‚ which is the defined as the shape of a network or how a network is laid out. Topology also consists of how the different components or nodes of a network are connected and how they communicate with each other. Topologies are either logical or physical. In addition‚ in the sections of this paper‚ I will compare and contrast some different conventional architecture and what types of

Bus Topology Bus networks (not to be confused with the system bus of a computer) use a common backbone to connect all devices. A single cable‚ the backbone functions as a shared communication medium that devices attach or tap into with an interface connector. A device wanting to communicate with another device on the network sends a broadcast message onto the wire that all other devices see‚ but only the intended recipient actually accepts and processes the message. Ethernet bus topologies are
Premium Network topology
A mesh network is a network topology in which each node (called a mesh node) relays data for the network. All nodes cooperate in the distribution of data in the network. A mesh network can be designed using a flooding technique or a routing technique. When using a routing technique‚ the message is propagated along a path‚ by hopping from node to node until the destination is reached. To ensure all its paths’ availability‚ a routing network must allow for continuous connections and reconfiguration

BUS TOPOLOGY REMAINS THE MOST USED Bus topology is the physical and logical design of a bus network. All the nodes (devices) on a bus network have to share access to the network to communicate. The nodes can only transmit data one device at a time. A bus is the central cable‚ the main wire that connects all devices on a LAN (Local Area Network). Bus topology is known as the simplest network topology‚ and also known as a linear bus (Oliviero and Woodward‚ 2009‚ p. 104). Bus topology is the

Benefits of a Hierarchical Network There are many benefits associated with hierarchical network designs. Scalability Hierarchical networks scale very well. The modularity of the design allows you to replicate design elements as the network grows. Because each instance of the module is consistent‚ expansion is easy to plan and implement. For example‚ if your design model consists of two distribution layer switches for every 10 access layer switches‚ you can continue to add access layer switches

match the cable type of the network. Most common hubs interconnect Category 3 or 5 twisted-pair cable with RJ-45 ends‚ although Coax BNC and Fiber Optic BNC hubs also exist. Ethernet Hubs An Ethernet hub is also called a multiport repeater. A repeater is a device that amplifies a signal as it passes through it‚ to counteract the effects of attenuation. Multistation Access Unit A Multistation Access Unit (MAU) is a special type of hub used for token ring networks. Switches Switches are

11. Your network consists of four servers. Each server has three NICs. Server A is connected to servers B‚ C‚ and D. Server B is attached to C and D. Server C is attached to server D. No hub is used. All cabling is CAT 3 UTP crossover cables. What is your physical topology? a. Star b. Bus c. Ring d. Mesh I believe this to be a mesh mainly because all the servers are connected to one another. There is no hub used and Cat 3 UTP would be the cable for use in a small topology such as this. Also‚

Network Design: Logical and Physical Design In networking terminology‚ the term network topology refers to the entire structure of the network. There are two primary parts to the topology definition: the physical design‚ which is the actual layout of the wire (media)‚ and the logical design‚ which defines how the media is accessed by the hosts. The physical designs that are commonly used in networks are the Bus‚ Ring‚ Star‚ Extended Star‚ Hierarchical‚ and Mesh. A bus topology uses a single
