Abstract: “Topology interconnection network Torus -Butterfly is a new Cartesian product interconnection network. It is cartesian product of Torus and Enhanced-Butterfly interconnection network. This topology has the properties of constant degree, small diameter and a smaller network cost. This paper discuss fault tolerance in the Torus-Butterfly interconnection network. The fault tolerance parameter is also one of the important parameters that need to be evaluated to determine the effetiveness of interconnection networks.”

Keywords: Torus-Butterfly, degree, diameter, network cost, fault tolerance
