Demand for mesh networks poised to rocket - Network IT Week

Demand for mesh networks poised to rocket - Network IT Week

Wireless MESH is probably the future, however it's extremely difficult to get right. If you can control the mesh then there's a chance that you can get it to work efficiently, however things tend to go horribly wrong when they get too big or allow "random" nodes to join.

In a mesh where you have n nodes (assuming a complete mesh i.e. each node connected to all others) the number of links is n(n-1)/2 i.e. for 4 nodes that's 6 links while 10 nodes is 45 links, 100 nodes is 4950 links etc. How you get data from a node to another requires routing tables to hold info on how the nodes are connected and this is where systems rapidly become unmanagable. Generally each node in the network needs to hold a complete routing table.

There are tricks to reduce the routing tables and only having certain nodes holding more info, but that's where clever design comes in.

If Cisco can crack this, the market could be huge.
