Static and Dynamic Interconnection Network

In a static network, the connection amid input and output nodes is permanent and can't be changed. Static interconnection network can't be reconfigured. The illustrations of this kind of network are ring, linear array, chordal ring, star, fat tree, mesh, tree, tours, hypercube, and systolic arrays. These kind of interconnection networks are more appropriate for building computers where communication pattern is more or less fixed and can be applied with static connections. In case of dynamic network, the interconnection prototype between inputs and outputs can be changed. The interconnection pattern is able to be reconfigured in proportion to the program demands.  Here rather than fixed connections, the switches or arbiters are used. Illustrations of these networks are multistage networks, crossbar switches, and buses.  The dynamic networks are commonly used in shared memory(SM) multiprocessors.
