摘要： The present disclosure is directed towards tracking application layer flow via a multi-connection intermediary. Transaction level or application layer information may be tracked via the intermediary, including one or more of: (i) the request method; (ii) response codes; (iii) URLs; (iv) HTTP cookies; (v) RTT of both ends of the transaction in a quad flow arrangement; (vi) server time to provide first byte of a communication; (vii) server time to provide the last byte of a communication; (viii) flow flags; or any other type and form of transaction level data may be captured, exported, and analyzed. The application layer flow or transaction level information may be provided in an IPFIX-compliant data record. This may be done to provide template-based data record definition, as well as providing data on an application or transaction level of granularity.

摘要： The present invention is directed towards systems and methods for efficient Xpath matching of a document comprising Extensible Markup Language (XML) or JavaScript Object Notation (JSON). A Xpath engine identifies an Xpath expression for processing values in the document, which is represented by a stack of nodes. The device may traverse the stack from top to bottom to match each step of the Xpath expression to a type and name of one or more nodes in the stack. The device may store a flag in each node that matches a step of the Xpath expression. Responsive to encountering a leaf node, the device may trace bottom to top from the leaf node to one or more flagged nodes in the stack and compare each flagged node against a corresponding step of the path expression. Responsive to the tracing of the flagged nodes, the device determines if the path expression is matched.
