Description of network topology of the office building. №2 The configuration, or topology, of a network is key to determining its performance. Network topology is the way a network is arranged, including the physical or logical description of how links and nodes are set up to relate to each other. There are numerous ways a network can be arranged, all with different pros and cons, and some are more useful in certain circumstances than others. Admins have a range of options when it comes to choosing a network topology, and this decision must account for the size and scale of their business, its goals, and budget. Several tasks go into effective network topology management, including configuration management, visual mapping, and general performance monitoring. The key is to understand your objectives and requirements to create and manage the network topology in the right way for your business. A network topology is a schematic description of how a network is organized, including nodes, connecting lines, and other devices. According to Table 7 above, the main network topologies are listed below. In-depth discussions of topologies are beyond the scope of this section of the course. However, below are brief descriptions of each topology and their images. Bus topology Bus networks (not to be confused with the computer's system bus) use a common backbone to connect all devices. One cable, the backbone, functions as a common communication medium to which devices are connected or connected using an interface connector. A device wishing to communicate with another device on the network sends a broadcast message over the wire that all other devices see, but actually receives and processes the message only the intended recipient. Star topology Many home networks use the "star" topology. A star-shaped network has a central connection point called a "hub node", which can be a network hub, switch, or router. Devices are usually connected to the hub via unshielded twisted pair (UTP) Ethernet. Compared to the bus topology, a star-shaped network usually requires more cable, but failure of any star-shaped network cable will result in network access being disabled for only one computer, and not for the entire LAN. (However, if the hub fails, the entire network also fails.) Ring topology In a ring network, each device has exactly two neighbors for communication. All messages pass through the ring in the same direction (either "clockwise" or "counterclockwise"). A failure in any cable or device breaks the loop and can disable the entire network. To implement a ring network, FDDI, SONET or Token Ring technologies are usually used. Ring topologies are found in some office buildings or school campuses. жүктеу/скачать 14.47 Kb.
