    摘要： A packet trace is received. The packet trace is transformed into a sequence of pulse signals in a temporal domain. The sequence of pulse signals in the temporal domain is transformed into a sequence of pulse signals in a frequency domain. Peaks are detected within relevant frequency bands in the sequence of pulse signals in the frequency domain. A fundamental frequency is identified within the peaks. The fundamental frequency, which represents the TCP flow clock, is returned.

    摘要： A traffic classifier has a plurality of binary classifiers, each associated with one of a plurality of calibrators. Each calibrator trained to translate an output score of the associated binary classifier into an estimated class probability value using a fitted logistic curve, each estimated class probability value indicating a probability that the packet flow on which the output score is based belongs to the traffic class associated with the binary classifier associated with the calibrator. The classifier training system configured to generate a training data based on network information gained using flow and packet sampling methods. In some embodiments, the classifier training system configured to generate reduced training data sets, one for each traffic class, reducing the training data related to traffic not associated with the traffic class.

    摘要： Methods and apparatus to implement scalable routing in network communication systems are disclosed. A disclosed example method involves selecting a plurality of virtual private networks in a communication network and selecting a candidate hub router from a plurality of routers in the communication network. The example method also involves determining a plurality of least memory utilization costs associated with assigning different quantities of spoke routers to the candidate hub router. Each of the least memory utilization costs and corresponding quantity of spoke routers is associated with a corresponding one of the plurality of virtual private networks. For each of the least memory utilization costs, a bandwidth usage of a corresponding one of the quantities of spoke routers is identified. The candidate hub router is selected to operate as a hub router for one of the quantities of spoke routers associated with a corresponding one of the bandwidth usages that does not exceed a bandwidth capacity of the candidate hub router.
