Abstract: 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.

Abstract: 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.

Abstract: Provided are a method and device for processing a data message. The method may include that: an Internet Protocol version 6 (IPv6) transition strategy used for executing an IPv6 transition technology is received from a Service function chain (SFC) controller; and a received data message is processed according to the received IPv6 transition strategy. By the technical solution, the problems of incapability of a network system in effective running during fusion with an IPv6 transition technology and incapability in effective implementation of unified deployment of the IPv6 transition technology in the related technology are solved, and the effects of effectively reducing performance pressure on an existing network and greatly alleviating channel congestion between equipment and equipment are further achieved.

Abstract: 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.

Abstract: The disclosure discloses a method and device for processing a Service Function Chaining (SFC). The method includes that: the SFC receives a message sent from forwarding equipment; the SFC generates a forwarding table corresponding to the message; and under a condition that a preset state of a forwarding table sending switch is on, the SFC sends the forwarding table to the forwarding equipment to make the forwarding equipment forward the message according to the forwarding table when receiving the message, wherein the forwarding table sending switch is used for indicating the SFC whether to send the forwarding table to the forwarding equipment or not. By the disclosure, an effect of increasing a success rate of data forwarding of the SFC is achieved.
