Mesh topology is one of the types of topologies that has a mesh layout, or a network structure where each computer or node and network device is interconnected with one another. This topology setup allows for most transmissions to be distributed even if one of the connections goes down.
In mesh topology, the nodes are connected to every other completely via a dedicated link during which information travels from nodes to nodes and there are N(N-1)/2 links in mesh if there are N nodes. Every node features a point-to-point connection to the opposite node.
The connections in the mesh topology can be wired or wireless.
DIFFERENT TYPES OF MESH TOPOLOGY –
Basically, there are 2 types of mesh topologies –
- Full – Mesh Topology : In a full mesh topology, every computer in the network has a connection to each of the other computers in that network. The number of connections in this network can be calculated using the following formula (n is the number of computers in the network): n(n-1)/2.
- Partial Mesh Topology : In this topology, only a few nodes are attached with all the other nodes. This means if one of the primary computers or connections in the network fails, the rest of the network continues to operate normally. It is less costly compared to full mesh topology and also it reduces the redundancy.
ADVANTAGES OF MESH TOPOLOGY
The following are the main advantages of using mesh topology –
- A failure of one device does not cause a break in the network or transmission of data.
- This topology provides multiple paths to succeed in the destination and tons of redundancy.
- It needs less investment in infrastructure as it is a highly decentralized system. Also, to manage the network, there are no central servers.
- This network design does not require any kind of central device or a centralized control system to operate.
DISADVANTAGES OF MESH TOPOLOGY –
However, using mesh topology is not advisable due to its following limitations –
- Building and maintaining the topology is difficult and time consuming.
- In mesh topology, Power requirement is higher as all the nodes will need to remain active all the time and share the load.
- In this topology, each node works as a router that increases complexity.
Thus, in a nutshell, A mesh topology is a network topology in which all the network nodes are individually connected to most of the other nodes.
