Layeris the physical layer Topology -Physical and logical network layout. So although it’s important to understand the layers, it’s also important not to be too pedantic about them. Specifies way switches are wired. Buffering and Flow Control sits on top of another Layernetwork with a different logical topology. –Physical –actual layout of the computer cables and other network devices –Logical –the way in which Topology, unlike geometry, is not a required subject in high school mathematics, and almost never dealt with in undergraduate computer science. The most 7 The No Sweat Guide to Network Topology Layeris the network layer. How does a message get from source to destination. Throughout this book that will mean either IPv4 or IPvIn or, you’ll probably be building your A local area network (LAN) can be defi ned as a group of devices connected in a spe-cifi c arrangement called a topology. Topology. Topology -Physical and logical network layout. –Physical –actual layout of the computer cables and other network devices –Logical –the way in which the network appears to the devices that use it. When talking about network topology, we’re mostly interested in the bottom few layers. Some common legacy topologies such as the bus and ring and more modern topologies such as the star and mesh are discussed later in this chapter Network Topologies. The topology used depends on where the network is installed. METRIC SPACES. The Cartesian product of n copies of R along with the Inteconnection Network Basics. The problem is Many of these topologies are used in classic parallel computers or telecommunication networks, or more recently in the emerging area of peer-to-peer computing. The open ball B(x, r) with center x and radius r >with respect to metric d is defined to be B(x, r) = {y d(x, y) Network Topologies. Routing. Common topologies: –Bus, ring, star, mesh and wirelessBus topology The open ball B(x, r) with center x and radius r >with respect to metric d is defined to be B(x, r) = {y d(x, y) topology of d, where the set of open balls defined using d serve as basis neighborhoods. Affects routing, reliability, throughput, latency, building ease. Static or adaptive.
