    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.

    摘要: A network system that reduces the computational resources to centrally-control network nodes in a border gateway protocol (BGP) network. More particularly, the systems and methods describe the control of a plurality of individual network nodes by a centralized controller, and the use of a route control server (RCS), which is connected to the centralized controller, or OpenFlow Controller (OFC). By treating the plurality of individual network nodes as a single combined network node, the route control server is able communicate using a single BGP speaker, and hence, reduce the computational resources from that required to run an individual BGP speaker for each individual network node.

    摘要: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for semi-centralized routing. One of the methods includes receiving one or more routes and determining that a received route identifies a new set of paths different from each routing path group in a maintained set of routing path groups. A new routing path group is created that corresponds to the new set of paths. The new routing path group is assigned an identifier of the routing path group. The new routing path group is converted to a corresponding new flow path group. A flow path group that was converted from the routing path group is replaced on a network device with the converted new flow path group.
