摘要
In one embodiment, a method comprises generating a switched link layer topology from a source device to a destination device, the switched link layer topology comprising a first sequence of switching devices, a second sequence of switching devices, and one or more bridging links between the first and second sequences of switching devices; generating first and second chains of resilient link layer segments for respective first and second multi-hop link layer connections based on generating a sequence of link layer loops overlying the switched link layer topology, and setting for each of the first and second multi-hop link layer connections a corresponding set of connection blocks in each link layer loop; and causing replication of a data packet across the first and second multi-hop link layer connections, enabling a failure in the switched link layer topology to be bypassed based on removing at least one of the connection blocks.
