For example, the sample diagram does not indicate the physical type of connection between the PCs and the switch, but since a modern LAN is depicted, Ethernet may be assumed. If the same style of line was used in a WAN (wide area network) diagram, however, it may indicate a different type of connection.
A network's physical topology is a particular concern of the physical layer of the OSI model. Examples of network topologies are found in local area networks , a common computer network installation. Any given node in the LAN has one or more physical links to other devices in the network; graphically mapping these links results in a geometric ...
The physical layout of the nodes in a network may not necessarily reflect the network topology. As an example, with FDDI, the network topology is a ring, but the physical topology is often a star, because all neighboring connections can be routed via a central physical location. Physical layout is not completely irrelevant, however, as common ...
Network architecture is the design of a computer network.It is a framework for the specification of a network's physical components and their functional organization and configuration, its operational principles and procedures, as well as communication protocols used.
A conceptual diagram of a LAN at a small business office; this example includes two rooms, each with a switch, as well as a file server, and a mix of wired and wireless connections. A LAN contrasts a wide area network (WAN) which not only covers a larger geographic distance, but also generally involves leased telecommunication circuits.
Network planning and design is an iterative process, encompassing topological design, network-synthesis, and network-realization, and is aimed at ensuring that a new telecommunications network or service meets the needs of the subscriber and operator. [1] The process can be tailored according to each new network or service. [2]
The collection of addresses in the network is called the address space of the network. Examples of telecommunications networks include computer networks, the Internet, the public switched telephone network (PSTN), the global Telex network, the aeronautical ACARS network, [1] and the wireless radio networks of cell phone telecommunication providers.
The network switch is only used to connect the server within a cell 0. A cell 1 contains k=n+1 cell 0 cells, and similarly a cell 2 contains k * n + 1 dcell 1 . The DCell is a highly scalable architecture where a four level DCell with only six servers in cell 0 can accommodate around 3.26 million servers.
