Abstract: A tunnel BFD session establishment method and device are provided. The tunnel BFD session establishment method includes: acquiring first content information, generating a first tunnel bidirectional forwarding detection (BFD) session establishment packet according to the first content information, and sending the first tunnel BFD session establishment packet to a second edge node; receiving a second tunnel BFD session establishment packet sent by the second edge node; and establishing a tunnel BFD session between the first edge node and the second edge node when the BFD status of the first edge node and the BFD status of the second edge node are a preset status. Therefore, the solution can solve a series of problems in the related art caused by that a tunnel BFD session can only be established by means of manual configuration, so as to achieve the effect of automatically establishing the tunnel BFD session.

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 translation: 提供了一种在OpenFlow网络中实现QoS的方法和设备。 该方法包括：对于进入OpenFlow交换机的分组，当流表成功匹配时，执行用于调用调度器并将分组添加到调度器中的指定队列中的指令; 并且在指令的触发下，通过使用调度器来管理队列调度。 通过使用本公开提供的技术手段，解决了OpenFlow交换机不能实现分层QoS（HQoS）的相关技术问题，从而OpenFlow交换机可以实现单层QoS和HQoS。
