NETWORK TOPOLOGY

Image
Network topology  is the arrangement of the elements (links, nodes, etc.) of a communication network.[1][2] Network topology can be used to define or describe the arrangement of various types of telecommunication networks, including command and control radio networks,[3] industrial fieldbusses and computer networks. Network topology is the topological[4] structure of a network and may be depicted physically or logically. It is an application of graph theory[3] wherein communicating devices are modeled as nodes and the connections between the devices are modeled as links or lines between the nodes. Physical topology is the placement of the various components of a network (e.g., device location and cable installation), while logical topology illustrates how data flows within a network. Distances between nodes, physical interconnections, transmission rates, or signal types may differ between two different networks, yet their logical topologies may be identical. A network’s physical to...

NETWORK TOPOLOGY (MESH ARCHITECTURE)

 Mesh networking Illustration of a partially connected mesh network. A fully connected mesh network is where each node is connected to every other node in the network. A mesh network (or simply meshnet) is a local network topology in which the infrastructure nodes (i.e. bridges, switches, and other infrastructure devices) connect directly, dynamically and non-hierarchically to as many other nodes as possible and cooperate with one another to efficiently route data from/to clients. This lack of dependency on one node allows for every node to participate in the relay of information. Mesh networks dynamically self-organize and self-configure, which can reduce installation overhead. The ability to self-configure enables dynamic distribution of workloads, particularly in the event a few nodes should fail. This in turn contributes to fault-tolerance and reduced maintenance costs. Mesh topology may be contrasted with conventional star/tree local network topologies in which the bridges/swi...
