Abstract: The present invention relates to the technical field of computer networking, in particular to an ID/location hybrid forwarding method based on source routing, including a message format based on an extension header of a MobilityFirst protocol, a source routing forwarding mechanism based on ID identifiers and a source routing forwarding mechanism based on location identifiers. Through the method of the present invention, the source routing forwarding mechanism based on ID identifiers can be adopted in the access domains of the MobilityFirst network to realize the internetworking of intra-domain networks, and the source routing forwarding mechanism based on location identifiers in the core domain realizes the interconnection of inter-domain networks; the method greatly simplifies the processing flow of the data plane of the MobilityFirst network, and meanwhile reserves the design that the ID identifiers and the location identifiers are separated, thereby effectively supporting intra-domain and inter-domain mobile data forwarding.

Abstract: A traffic alarm method and apparatus based on a programmable switch, a device and a medium. The method monitors traffic with different priorities, when the traffic is greater than or equal to a threshold, the programmable switch may give a real-time alarm on a data plane and return low priority traffic information in a current network back to a sending end, and the sending end may adjust a task priority through alarm information. The present disclosure uses a programmable switch device, the lower priority traffic information may be alarmed to the sending end in real time on the data plane without passing through a controller, an alarm delay is significantly reduced, the sending end may adjust a sending rate timely, real-time scheduling of network traffic is achieved, high priority traffic transmission is ensured, and meanwhile link utilization is improved.

Abstract: The present application discloses a DQN-based distributed computing network coordinate flow scheduling system and method. The method includes: establishing environmental feature data based on distributed computing task information and a congestion situation of a port queue in a programmable forwarding platform on a data plane, establishing and training a deep reinforcement learning intelligent agent based on an action value network and a target network in DQN, and the deep reinforcement learning intelligent agent outputting abstract actions; receiving, by a policy mapper, the abstract actions and mapping them into an executable coordinate flow scheduling policy; executing, by the programmable forwarding platform, the executable coordinate flow scheduling policy and updating the congestion situation of the port queue; and recording, a policy gainer, a completion time of a distributed computing task as a real-time reward of the deep reinforcement learning intelligent agent and iteratively optimizing the deep reinforcement learning intelligent agent.
