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.
And, my house now has a Mesh WiFi Network.
With a mesh, the lack of dependency on one node allows for every node to participate in the relay of information. Mesh networks dynamically self-organise and self-configure. 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. But, I bagged a bargain on Amazon and they were still damn expensive.
What the hell am I on about? I am speaking about the small white disks that now reside in our rooms in our place – this has made a WiFi Mesh Network.
Although mostly used in wireless situations, this concept can also apply to wired networks and to software interaction.
With routing, the message is propagated along a path by hopping from node to node until it reaches its destination. To ensure that all its paths are available, the network must allow for continuous connections and must reconfigure itself around broken paths, using self-healing algorithms such as Shortest Path Bridging. Self-healing allows a routing-based network to operate when a node breaks down or when a connection becomes unreliable. As a result, the network is typically quite reliable, as there is often more than one path between a source and a destination in the network.
So, in essence, we have great WiFi!
