All you need to know about the network topology

Network architecture, including its topology and protocols used, directly affects its performance, including performance and fault tolerance. To estimate the total network performance need to be considered as the performance of each connection, and the number of connections and devices, among which can be distributed traffic. For example, in a traditional LAN topology with two central switches and Spanning Tree protocol for switching in each direction will be available for only one compound, while in a two-tier network of Spine-Leaf’s Internet Protocol Cisco Fabricpath can simultaneously use up to 16 connections that can significantly improve overall performance. addition, network performance for a specific device connected affects the so-called “over-subscription ratio,” which is the ratio of the overall performance of end network connectivity and performance of the “narrow” places in the network, through which the traffic is these connections and which is also determined by the topology of the network and the protocol.

The topology of a network can be represented by the sum of its physical and logical connections. in the classic sense, there are three basic network topologies – bus, ring and star. But all modern networks typically are hybrid versions, that is made ??up of segments that use different base topology. One of the main parameters on network performance is the data transfer rate. If we consider the transfer of data from one network to another point, then, in general, it is determined by the speed of the slowest connection and the current load on the network as a whole. Since it is determined by the topology of the presence of certain compounds, one can safely say that it is directly affects the transmission speed and performance of the network as a whole. Only with proper planning, topology, including the number, type and direction of the transmitted data, it is possible to maximize network performance.
