摘要： 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. Thus the present invention has the advantages of effectively reducing the investment on detection device, The overhead of exchanging monitoring information and the detection system maintenance cost; facilitating cross domain coordination; and efficiently handling the failures occurring during network operation in time; effectively improve the reliability of the network, being suitable for a large-scale network.

摘要： 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.

摘要： A buffer device includes at least one internal switching unit and at least one basic buffer unit. The internal switching unit includes at least two inputs and at least two outputs. The internal switching unit and the basic buffer unit form a closed connection by alternating with each other via one input of the two inputs and one output of the two outputs. Another one of the at least two inputs of the internal switching unit receives a light wave. The internal switching unit outputs the light wave according to a first control signal. The basic buffer unit buffers the lightwave from the internal switching unit. At the same time, a network node and a scheduling method are also provided. A network node with the buffer device has a small scale and is easy to realize, while the data packet loss rate is decreased and the head of line blocking is avoided.
