摘要： A packet trace is received. Inter-arrival times between the multiple packets in the packet trace are determined. An inter-arrival time in the inter-arrival times that is greater than a threshold is identified. An order number of the inter-arrival time is identified. A determination is made as to whether a size of each of at least a portion of the multiple packets is equal to a maximum segment size. When a determination is made that the size of each of at least a portion of the multiple packets is equal to the maximum segment size, a size of the ICW as a product of the order number and the maximum segment size is returned.

摘要： Two methods and computer-readable medium for obtaining information using field group unpacking functions. The first method obtains information using field group unpacking functions by identifying an optimized unpacking function from field group unpacking functions, and an optimized unpacking function is used to unpack a field associated with the data stream. The second method obtains information using field group unpacking functions by identifying an optimized unpacking function from the field group unpacking functions. Then, a prefilter is applied and associated with the optimized unpacking functions and used to unpack a field associated with the data stream. The computer-readable medium obtains field group unpacking functions for execution by a computing device using field group unpacking functions that identify an optimized unpacking function from the field group unpacking functions, and use an optimized unpacking function to unpack a field associated with the data stream.

摘要： A signature-based traffic classification method maps traffic into preselected classes of service (CoS). By analyzing a known corpus of data that clearly belongs to identified ones of the preselected classes of service, in a training session the method develops statistics about a chosen set of traffic features. In an analysis session, relative to traffic of the network where QoS treatments are desired (target network), the method obtains statistical information relative to the same chosen set of features for values of one or more predetermined traffic attributes that are associated with connections that are analyzed in the analysis session, yielding a statistical features signature of each of the values of the one or more attributes. A classification process then establishes a mapping between values of the one or more predetermined traffic attributes and the preselected classes of service, leading to the establishment of QoS treatment rules.

摘要： A system and method for detecting and diagnosing routing problems in a network in real-time by recording TCP flow information from at least one server to at least one prefix, and observing retransmission packets communicated from the at least one server to the at least one prefix. When a predetermined threshold for TCP flows to a prefix is reached, traceroutes may be triggered to a destination in the prefix, and the traceroutes analyzed to determine whether to issue an alarm for a routing failure. The system includes a real-time data collection engine for recording unidirectional TCP flow information, a real-time detection engine for observing the retransmission packets and issuing a warning upon a retransmission counter exceeding a predetermined threshold, and a real-time diagnosis engine for triggering at least one traceroute to a destination in the prefix that is randomly selected from TCP flows in retransmission states.
