Mesh Topology

Mesh topology is a form of relationship between devices where each device is connected directly to another device that making each device can communicate directly with the target device (Dedicated Links). The number of connections between devices on the network topology Mesh can be calculated as n (n-1) / 2. Since each device can be connected to other devices on the network, each device must have a Port Input / Output as much or more than n-1.
  Based on the understanding, can be exemplified that when as many as five computers will be connected in a mesh topology, so to make connections between computers can function optimally, required cable connection 5 (5-1) / 2 which is 10 cable connections, and their each computer has a Port Input / Output as many or more than 5-1 which is 4 port. And if there are 8 computers will be connected in a mesh topology, the required cable connections by 8 (8-1) / 2 which is 28 cable connections, and each computer has a Port Input / Output as much or more than 8-1 which is 7.
  With the form of such a relationship, Mesh topology has several advantages, that are:• Dedicated Relationship Links directly to ensure the data is sent to the destination computer without having to go through other computers so that they can more quickly because of the special relationship is used to communicate with the destination computer only (not used in a gang).• If an interruption in the connection of computer A with computer B because of damage to the cable connection between A and B, the disorder does not affect the connection of computer A to another computer.• Communication between two computers will not be accessible by other computers.  Facilitate the identification of problems in the event of damage to connections between computers.Nonetheless, Mesh topology has some drawbacks, that are:• Requires a lot of wiring and Port Input / Output on any device. More and more devices in the Mesh topology is needed more and more cable and Port Input / Output.• This type of topology requires very expensive.• Because each computer must be connected directly to another computer then the installation and configuration becomes more difficult.• The number of wires used also makes the need for space that allows to compose cable in the room where the computers are located.Based on the advantages and disadvantages, Mesh topology is usually used on the main computers where each main machine Formatting separate networks with different topologies.
