Abstract
The invention discloses a cross-layer network fault recovery system and method based on configuration migration. The method includes: an upper layer switching network controller sends device fault information to a super controller; the super controller performs a fault device location, and selects a backup upper layer switching network device in an upper layer switching network; the super controller generates a third forwarding table, and delivers the third forwarding table to an upper layer switching network controller and an underlying layer switching network controller; the upper layer switching network controller generates a first forwarding table to be updated according to the third forwarding table, and delivers the first forwarding table to neighbor devices of the fault device and the backup upper layer switching network device; the underlying layer switching network controller calculates underlying layer switching network transmission channels according to the third forwarding table, and updates a second forwarding table of the underlying layer switching network devices on these transmission channels. The invention utilizes the reconfigurability of the underlying layer switching network to allow rapid replacement of the fault device and service recovery in the upper layer switching network.
