Abstract

Embodiments are directed towards managing network routes using a centralized service on behalf of a network of a plurality of forwarding devices. The centralized service develops a global view of the network based on information from the forwarding devices. The centralized service computes changes to the routing policy for each of the nodes. The centralized service then generates an operational command schedule that is distributed to the forwarding devices using a “make before break” sequence to ensure that transient black holes do not happen as the new routing policy is being implemented.
