摘要： A method and apparatus for reporting a feature of an OpenFlow switch are provided. The method includes: when the OpenFlow switch learns that an OpenFlow controller needs to query for port information, reporting port group identifiers of port groups, to which each port of the OpenFlow switch or each port to be queried by the OpenFlow controller belongs, to the OpenFlow controller, herein the port groups are obtained by grouping ports with different features in the OpenFlow switch based on one or more feature types, and each of the port groups has a port group identifier.

摘要： A cross-domain clock synchronization method, device and system and a computer storage medium, which are applied to a cross-domain synchronization network. A Path Calculate Element (PCE) exchanges a clock synchronization type with a controller participating in clock synchronization path calculation to match the clock synchronization type supported by the PCE and the controller; the PCE acquires physical topological information of the cross-domain synchronization network; the PCE acquires synchronization information of synchronization nodes of the cross-domain synchronization network and/or hop number information between the synchronization nodes; the PCE calculates a clock synchronization path of the cross-domain synchronization network according to the physical topological information as well as the synchronization information and/or the hop number information; and the PCE sends the clock synchronization path to the controller according to the physical topological information to enable the controller to send a clock synchronization instruction to synchronization nodes on the clock synchronization path.

摘要： Disclosed is a method and system for encapsulating a flow identifier. The method for encapsulating a flow identifier comprises: in the case where flow table matching is successfully performed on a packet, an OpenFlow switch adds a flow identifier to the packet; and the OpenFlow switch invokes a pre-saved function entry to assign a value to the flow identifier, so as to complete the encapsulation of the flow identifier. The disclosure achieves the effect of enabling an OpenFlow network node to take a hash calculation result of some fields of an original packet before encapsulation as the assignment of a new added flow identifier, which is required by the encapsulation of the flow identifier.

摘要： Provided are a method and device for implementing QoS in an OpenFlow network. The method includes that: for a packet entering an OpenFlow switch, when a flow table is successfully matched, an instruction which is used for calling a scheduler and adding the packet into a specified queue in the scheduler is executed; and under the triggering of the instruction, queue scheduling is managed by using the scheduler. By using the technical means provided by the disclosure, the technical problem in related art that the OpenFlow switch cannot implement Hierarchical QoS (HQoS) is solved, so that the OpenFlow switch may implement both single-layer QoS and HQoS.
