Abstract
Systems and methods are provided for managing a data communication within a multi-level network having a plurality of switches organized as groups, with each group coupled to all other groups via global links, including: at each switch within the network, maintaining a global fault table identifying the links which lead only to faulty global paths, and when the data communication is received at a port of a switch, determine a destination for the data communication and, route the communication across the network using the global fault table to avoid selecting a port within the switch that would result in the communication arriving at a point in the network where its only path forward is across a global link that is faulty; wherein the global fault table is used for both a global minimal routing methodology and a global non-minimal routing methodology.
