Wan Topology
The topology described here is a physical topology, but this necessarily does not have to be the case, it can have a Logical Topology which can be, for instance, a Logical Bus Topology. Ring network topology means that, devices connected according this topology have two connections, connecting with nearby devices to make a loop. As a general rule, reliability increases with the number of potential routes data can follow. It is essentially the topological structure of a network and can be depicted physically or logically. A network architect can determine the best placement of top-level routers based on traffic patterns or critical data paths. Some of the most common network topologies are: Physical Topology Physical Network Topology emphasizes the hardware associated with the system including workstations, remote terminals, servers, and the associated wiring between assets. Ring topology has no end points.
Ring Network Topology As the name suggests the Ring topology orientation has sites arranged in a ring. What is Network Topology The physical topology of a network refers to the configuration of cables, computers, and other peripherals. When a network is wired, it uses cables to connect group of computers together to enable data communication. We will be using cisco Hubs and switches and wireless access points. Write a short memo describing the upgrade and, if possible, include a drawing of the new network. Currently, Franklin Engineering operates a small office in the United States, and its network is very basic. We would have to buy five wireless nic-cards to start to accommodate the cabling issue in the warehouse as well as a wireless access point and a wireless router.
There are used common icons for the Network diagrams design, such as icons of various network appliances, computer devices, routers, clouds, peripheral devices, digital devices, etc. Network diagram is a chart which represents nodes and connections between them in computer network or any telecommunication network, it is a visual depiction of network architecture, physical or logical network topology. Any planning begins with an analysis of the business requirements to the final system. Star-Wired Ring A star-wired ring topology may appear externally to be the same as a star topology. This is illustrated in Figure 3. Ring topology has some benefits such as equal access to everyone, transformation of data at very high speed but has disadvantages like the fault in any cable or wire may cause of failure network.

Star Star networks have nodes connected to a central hub like the spokes of a wheel See Reference 4. Computers are connected by means of a communication network in a distributed computing environment which is arranged in a geometrical shape called network topology. This means the broadcasts from workstations won't hamper the servers and vice. The files need to be accessed by all 10 users, and each user must have different security rights. 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. Each site is connected to each other as seen in Figure 4 with the last and first sites connected completing the ring. Words: 565 - Pages: 3.
It is also easy to add or remove a nodefrom the network. All stations share this cable segment. This long-overdue upgrade is necessary because of poor network response time caused by a lot of collisions occurring during long file transfers between clients and servers. Tree Topology Tree topologies integrate multiple star topologies together onto a bus. In addition, all traffic must be sent through the hub, which can create bottlenecks. Words: 648 - Pages: 3.

Words: 749 - Pages: 3. Network Topologies When describing any computer network, we imagine a set of devices and nodes, arranged in some way. The computers providing the service are called servers and the computers that request and use the service are called client computers. Cellular networks exhibit interesting characteristics since this topology do not depend on cables. Case Project 2-2 This Case Project advises of a network that has 200 workstations and four servers connected by multiple switches.
These combinations are called hybrid topologies. Variations on this topology abound. Advantages and Disadvantages It is very easy to install and manage star network topology as it is the simplest of the lot when it comes to functionality. A consequence is that if you configure an ad-hoc network on a standard Wi-Fi certified laptop, your setup will limit your ad-hoc network to 2. The logical topology visually displays network dataflows from one device to another. Without a good grasp of the terminology, it will be difficult to understand the concepts and processes involved in networking. How do you recommend upgrading this network? The difference is that data moves up and down a linear connection, copying itself where network equipment works as bus-stations along the way.
Also cisco routers, modems and of course our firewall by Barracuda. For example, when you attach your computer to a printer, you have created a point-to-point link. The internet with the help of the network has given people new ways to get communication, entertainment, and information. If the line is clear the computer sends the data, if not the computer waits. A first station defines the radio parameters and a connection name; the other stations just need to detect the connection and adjust their own parameters to connect to the first station and to each other. This article introduces the standard topologies of computer networking. It means the arrangement of devices on a computer network through the actual cables.
