Implementations for management resilience with route persistence and state reconciliation in an accelerator interconnect network. In some implementations, a system comprises accelerators coupled to switches via protocol-level interface links, the switches storing forwarding entries in hardware, each forwarding entry mapping a destination accelerator identifier to an egress port.
