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. A centralized controller generates and distributes the forwarding entries via management agents.

In some implementations, upon recovery, the centralized controller re-establishes connections to management agents, re-gathers identity, configuration, and operational state, identifies discrepancies between intended and actual configuration, pushes corrections, and recalculates forwarding entries. The reconciliation may use differential comparison with cached pre-failure state and may prioritize data plane correctness.
