A grid network is a computer network consisting of a number of computer systems connected in a grid topology.
In a regular grid topology, each node in the network is connected with two neighbors along one or more dimensions.
If the network is one-dimensional, and the chain of nodes is connected to form a circular loop, the resulting topology is known as a ring.
Network systems such as FDDI use two counter-rotating token-passing rings to achieve high reliability and performance.
A parallel computing cluster or multi-core processor is often connected in regular interconnection network such as a de Bruijn graph,[1] a hypercube graph, a hypertree network, a fat tree network, a torus, or cube-connected cycles.
