  • Sampling and analyzing packets in a network
    Patent number: 7852785
    Abstract: The preferred embodiments of the present invention can include sampling packets transmitted over a network based on the content of the packets. If a packet is sampled, the sampling unit can add one or more fields to the sampled packet that can include a field for a number of bytes contained in the packet, a packet count, a flow count, a sampling type, and the like. The sampled packets can be analyzed to discern desired information from the packets. The additional fields that are added to the sampled packets can be used during the analysis.

  • Flexible Application Classification
    Publication number: 20100146100
    Abstract: A system includes an information storage module and an inspection module. The information storage module is configured to store a plurality of tags. Each tag is associated with a known set of traffic types of a plurality of known sets of traffic types. The inspection module is configured to compare a traffic flow to a set of traffic types to determine a matching set of traffic types, request a tag from the information storage module, and mark the traffic flow with the tag. The tag corresponds to the matching set of traffic types.

  • METHOD AND APPARATUS FOR MANAGING HIERARCHICAL COLLECTIONS OF DATA
    Publication number: 20080109493
    Abstract: A method and system provide for management of a collection of data records. The data records have associated therewith an identifier or code that indicates the most coarse level of granularity with which the data record is associated in a hierarchy of sampling subsets created across a range of granularity levels.
