摘要： 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.

摘要： Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for semi-centralized routing. In one aspect, a computer-implemented method receives a network protocol packet at a router adapted for routing data packets to one or more additional routers. The network protocol packet conforms to a routing protocol that provides distributed routing computation. The method also sends the network protocol packet, through a controller, to a selected one of a plurality of route control servers. The method also processes the network control packet at the selected route control server to generate a routing computation result that conforms to the routing protocol. The method also generates routing information based on the routing computation. The routing information conforms to a control protocol that provides centralized routing computation. The method also sends the routing information to the router for routing of data packets based on the control protocol.
