Abstract: A network topology discovery method and system are disclosed, which relates to the field of software defined network architecture, and solves a problem that greater pressure is easily put on a control channel in a case that a great many switches and ports exist. The method includes: a controller receiving a message sent by a network device, wherein the message carries a device ID of a network device where a link far-end port of the network device is located and a port number of the link far-end port; and the controller performing topology discovery on a network according to the message. The technical scheme provided in the present document is applicable to a software defined network, which achieves that related parameters are carried to the controller via an OpenFlow protocol.

Abstract: A method for computing a frequency slot channel, a path computation element and a node are disclosed. The method includes: when a frequency slot channel needs to be established, an ingress node sending to a path computation element a path computation request message which carries spectrum resource information needed for establishing the frequency slot channel; according to the received spectrum resource information sent by the ingress node, the path computation element computing out the frequency slot channel by combining of topology information of a network and spectrum resource information of each node in the network. The path computation element includes a receiving module and a computing module. When working as an ingress node in a process of establishing a frequency slot channel, the node includes a message construction module and a sending module.
