摘要： In accordance with an aspect of the invention, a method and system are disclosed for constructing an embedded signature in order to facilitate post-facto detection of leakage of sensitive data. The leakage detection mechanism involves: 1) identifying at least one set of words in an electronic document containing sensitive data, the set of words having a low frequency of occurrence in a first collection of electronic documents; and, 2) transmitting a query to search a second collection of electronic documents for any electronic document that contains the set of words having a low frequency of occurrence. This leakage detection mechanism has at least the following advantages: a) it is tamper-resistant; b) it avoids the need to add a watermark to the sensitive data, c) it can be used to locate the sensitive data even if the leakage occurred before the embedded signature was ever identified; and, d) it can be used to detect an embedded signature regardless of whether the data is being presented statically or dynamically.

摘要： Disclosed is a method and apparatus for compensating for a performance degradation of an application session in a plurality of application sessions associated with a network link. The performance of each application session in the plurality of application sessions associated with the network link is determined. The performance of each application session in the plurality is then compared. From this comparison, a lowest performance application session in the plurality of application sessions is identified. Corrective action is performed on packets scheduled to be transmitted over the lowest performance application session.

摘要： The present invention is a method for improving delivery of content to a client communicating with a server on the Web. Groups or clusters of clients are formed by processing the IP addresses of the clients according to a network-aware, radix-encoded trie classification process. The groups of clients are categorized based on information about one or more clients in each group that can be determined by the server. That information is used to help drive tailored actions on the part of Web servers. Users with poor connectivity may choose not to spend much time at a Web site if it takes a long time to receive a page, even if the Web server at the site is not the bottleneck. Retaining such clients may be of interest to a Web site. Better-connected clients may be able to receive enhanced representations of Web pages such as with higher quality images.

摘要： The present invention increases the efficiency of performing longest prefix matching operations by selecting a radix-encoded trie structure optimized with respect to memory cost. The structure is optimized by determining memory costs for retrie structures indexed on different numbers of high-order characters, and then selecting the structure corresponding to the lowest memory cost. The optimization improves performance in IP look-up operations as well as longest-prefix matching operations performed on general alphabets.

摘要： Disclosed is an informed sampling technique for biasing a sample data set toward network data of interest for a particular application. Network data received at a network node (for example at a rate which is greater than a sampling rate for which the network node is configured) is chosen to be included in a sample set based on one or more predetermined signatures which are chosen to bias the sample set toward network data of interest for a particular application. For example, the sample set may be biased to include data of interest for fraud detection, spam detection, and intrusion detection. The particular signature(s) may be predefined by a user, or may be automatically generated by another network application. The invention may be implemented at various levels and nodes of a network. For example, the informed sampling may be implemented at a traffic monitoring function of a network router, a flow collector which receives network flow data from the router, or both.
