Mesh topology
Mesh topology Every devices has a dedicated point to-point- link to every other device. To find the number of physical links in a fully connected mesh network with n nodes, we first consider that each node must be connected to every others nodes. Number of physical link=n(n-1) If each physical link is duplex, we can divide the number of links by 2, (n(n-1))/2. Advantage Eliminate traffic problem Robust. If one of the link is unusable, it will not effect the entire system Privacy and security Disadvantage installation and re-connection are difficult Wiring and cable required large spaces because required many cable in mesh topology Hardware can be expensive (Need lot of I/O port and cable) One practical example of mesh topology is the connection of telephone regional offices in which each regional office need to be connected to every other regional office.
