Types of Network Topologies

The following are five network types and the definitions of each.

• Mesh
• Star
• Bus
• Ring
• Hybrid

Mesh Topology

In this topology each device is connected to each other device on the network through an obsessive point-to-point link. once we say dedicated it means the link only carries data for the 2 connected devices only. shall we say we’ve got n devices within the network then each device must be connected with (n-1) devices of the network. Number of links in a very network topology of n devices would be n(n-1)/2.

Advantages

1. No data traffic issues as there’s a frenzied link between two devices which suggests the link is merely available for those two devices.
2. topology is reliable and robust as failure of 1 link doesn’t affect other links and therefore the communication between other devices on the network.
3. mesh is secure because there’s some extent to point link thus unauthorized access isn’t possible.
4. Fault detection is straightforward.

Disadvantages

1. Amount of wires required to connected each system is tedious and headache.
2. Since each device must be connected with other devices, number of I/O ports required must be huge.
3. Scalability issues because a tool can’t be connected with sizable amount of devices with an obsessive point to point link.
