    Abstract: 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.

    Abstract: A system for visualization of performance measurements is disclosed. The system may include an electronic data processor configured to receive a stream of the performance measurements and select a maximum number of leaf nodes of a plurality of nodes for use in an adaptive decision tree. Additionally, the electronic processor may be configured to determine a depth of each branch in the adaptive decision tree needed to differentiate performance among internet protocol addresses in an internet protocol prefix of each node. Each of the plurality of nodes may be annotated with a predicted latency category and the processor may be configured to generate the adaptive decision tree based on the maximum number of leaf nodes selected, the depth of each branch determined, the predicted latency category, and on the stream of performance measurements associated with the network. Moreover, the processor may display the adaptive decision tree.

    Abstract: A method and apparatus for providing performance measurements on network tunnels in packet networks are disclosed. For example, the method establishes two tunnels between a first measurement host and a first router, and establishes a tunnel between the first router and a second measurement host. The method also establishes a multicast group having a plurality of members, and sends one or more packets addressed to the multicast group from the first measurement host. The method measures the frequencies of directly and/or indirectly received responses from the plurality of members of the multicast group, and provides a plurality of estimated values for a plurality of packet transmission rates from measurement of the frequencies for one or more of said tunnels.
