Abstract: A computing system including network elements arranged in at least one group. A plurality of the network elements are designated as spines and another plurality are designated as leaves, the spines and leaves are interconnected in a bipartite topology, and at least some of the spines and leaves are configured to: receive in a first leaf, from a source node, packets destined to a destination node via a second leaf, forward the packets via a first link to a first spine and to the second leaf via a second link, in response to detecting that the second link has failed, apply a detour path from the first leaf to the second leaf, including a detour link in a spine-to-leaf direction and another detour link a leaf-to-spine direction, and forward subsequent packets, which are received in the first leaf and are destined to the second leaf, via the detour path.
