The logic is configured to receive one or more software defined network (SDN) routes dictating a path through a network comprising a plurality of devices. The logic is also configured to store the one or more SDN routes to the memory along with one or more traditional routes learned by the apparatus and/or configured by an administrator, and indicate the one or more SDN routes as being of a type different from the traditional routes. Moreover, the logic is configured to receive a priority ordering for a plurality of routes stored in the memory from the SDN controller, the plurality of routes including at least one SDN route, and construct a route information base (RIB) based on the plurality of routes and the priority ordering. | 01-28-2016 |
| 20160050143 | TRANSPORT NETWORK CONTROL METHOD, CONTROLLER AND NODE - Embodiments of the present invention provide a transport network control method, a controller, and a node. The method includes: receiving, by a controller, a control request message of a path; determining, according to topology information of a transport network and an atomic behavior that is supported by each node in the transport network, at least one node that the path passes through in the transport network and at least one atomic behavior that the at least one node needs to execute; and sending a path configuration message that includes the atomic behavior to the at least one node correspondingly, so that each node configures a transport plane to execute the atomic behavior included in the message. | 02-18-2016 |
| 20160065458 | System, Method and Device for Forwarding Packet - Provided are a system, a method and a device for forwarding a packet. The system comprises: an LCC comprising a first LCC's control ether switch unit and a second LCC's control ether switch unit, a first CFC comprising a first CFC's control ether switch unit, and a second CFC comprising a second CFC's control ether switch unit, wherein a control message channel and a protocol packet channel are separately arranged between the first and the second LCC's control ether switch units and the first and the second CFC's control ether switch units. Through the disclosure, the problem that the reliability and security of the cluster-based router may be reduced if the control message and the protocol packet are transmitted in the same channel in the related arts is solved, so as to achieve the effects of forwarding the control message and the protocol packet in a cluster-based router separately and enhancing the reliability and the security of the cluster-based router. | 03-03-2016 |
| 20160065696 | NETWORK ROUTING - Measures for transferring routing protocol information between a software defined network and one or more external networks are provided. A control node in a software defined network (SDN) is configured to maintain a protocol information database comprising routing protocol information for one or more switching nodes in the SDN. In response to detecting occurrence of a predetermined trigger event, the control node modifies the routing protocol information in the protocol information database, and determines whether the one or more switching nodes include an edge switching node. In response to the determination, a routing protocol message is transmitted from the control node to the edge switching node for forwarding via an external network interface. The routing protocol message includes data generated on the basis of the modified routing protocol information. | 03-03-2016 |
| 20160134522 | DATA FLOW PROCESSING METHOD, DEVICE, AND SYSTEM - Embodiments of the present invention relate to the field of communications technologies and disclose a data flow processing method, a device, and a system, thereby solving a problem of operation interruption caused because a switch device is incapable of processing a corresponding user packet by using a received flow entry that is sent in advance by a control device, and improving working efficiency between network devices. The method includes: sending a request message to a control device, where the request message includes an action parameter requested by a switch device, and a to-be-processed packet or an identifier of a to-be-processed packet; receiving packet processing information that is sent according to the request message by the control device; and executing, according to the packet processing information, an operation corresponding to the to-be-processed packet. The embodiments of the present invention are applied in communications application technologies. | 05-12-2016 |
