Abstract: A method includes identifying a switching path for source ports and destination ports of a crosspoint based switch including a two-tiered spine-and-leaf architecture. The method includes determining whether a switching path for a connection between a source port and a destination port is available, and identifying whether the source port and the destination port are associated with a same leaf. In response to determining that the switching path is available, the method includes executing a connection between the source port and the destination port utilizing a switching path on the same leaf. In response to determining that the switching path is unavailable, the method includes identifying whether free connections are available between a source leaf and a spine and a destination leaf and the spine. When the free connections are unavailable, the switching path for the connection between the source port and the destination port is executable by rewiring.
