Abstract: The present invention relates to a method for detecting Network Anomaly in network architectures based on locator/identifier split, the detection flow is as follows: initialization processing, and in ITR: processing data packets, sending a Map-Request, determining whether to send an additional Map-Request, sending the data packet, processing the Map_Reply, processing EID-to-RLOC Cache entry expired; in ETR: processing data packet, processing Map-Request, determining whether the traffic of the ITR currently sending the Map-Request is abnormal, replying to the ITR of which the query traffic is abnormal, replying to ITR of which the query traffic is abnormal. With respect to the characteristic that the network architecture based on locator/identifier split needs to query the relationship between the locator and the identifier for packet delivery, the present invention detects Network Anomaly based on query traffic instead of network data packet traffic.

Abstract: A method and a core router for implementing forward delay for bursts are disclosed. The core router configured with an FDL performs proactive delay processing for the burst to be overlapped after predicting that the burst will be overlapped on the link to be protected, thus reducing the probability of burst conflict on the downstream link to be protected. After finding that burst conflict will occur on the output port of the core router at a future moment, the core router sends a burst delay request to the upstream core router, requesting the upstream core router that has an FDL and the delay capability to delay the burst. Therefore, the FDL configured in the network is brought into full play, and the probability of burst conflict is reduced.

Abstract: A method for controlling burst assembly, device, and communication equipment thereof are provided. In the present invention, an assembly time and a predetermined time threshold are compared to determine a load change in a cache queue. If the load is increased or decreased suddenly, a length threshold is directly increased or decreased. If the load is to be increased, the length threshold is randomly increased according to a certain probability. If the load is to be decreased, the length threshold is randomly decreased according to a certain probability. If the load is in a normal state, the length threshold is maintained. Therefore, the length threshold is dynamically adjusted with the load change. The method and device provided by the present invention ensure an end-to-end (E2E) delay of the services and optimize the network performance.
