摘要： A method is disclosed for high-speed processing of structured application messages in a network device. According to one aspect, a network device receives a set of message classification rules that have been prepared beforehand by a system administrator or customer. The system analyzes the message classification rules to determine what part(s) of the message are necessary to classify a message according to the message classification rules. This allows the system to consider only the relevant parts of the message and ignore the rest of the message. The system extracts the portion of the message necessary for classifying the message and classifies the message using the values of the extracted information and the message classification rules. A unique sequence of operations is implied by the message classification and those operations must then be applied to the message.

摘要翻译： 公开了一种用于在网络设备中高速处理结构化应用消息的方法。 根据一个方面，网络设备接收由系统管理员或客户预先准备的一组消息分类规则。 系统分析消息分类规则，以根据消息分类规则确定消息的哪些部分是必要的，以对消息进行分类。 这允许系统仅考虑消息的相关部分，并忽略消息的其余部分。 系统提取消息分类所需的部分，并使用提取的信息和消息分类规则的值对消息进行分类。 消息分类暗示了唯一的操作序列，然后必须将这些操作应用于消息。

摘要： A network infrastructure element such as a router or switch performs transparent and optimized validation of XML schemas of XML payloads received in the network element. The network element comprises logic for receiving and storing one or more validation scope rules that define a portion of an extensible markup language (XML) schema for validation; receiving and storing the XML schema; receiving over the network an application-layer message comprising one or more of the packets; identifying a particular XML element in an XML payload of the application-layer message, wherein the particular XML element is within the portion of the XML schema defined in the one or more validation scope rules; determining whether the particular XML element conforms to the XML schema; and performing a responsive action based on whether the particular XML element conforms to the XML schema.

摘要： In an embodiment, an XPath automaton with state look-ahead capability can efficiently determine whether XML documents, received in a stream in serialized form in a network element, match any of a set of XPath expressions. A token processor receives a structured electronic document in serialized format and identifies entities. A name recognition engine recognizes names of elements of the document and recognizes names of attributes of the elements. A finite state automaton comprises states and transitions representing structural relationships among elements and attributes of structured path expressions and state look-ahead logic that is configured to output a final state when an entity matches one or more of the structured path expressions. The automaton performs state transitions resulting in reaching a specified final state if a match to an expression occurs.

摘要： In an embodiment, a data processing system comprises application workflow optimizing logic and which when executed is operable to receive first workflow data that defines a sequence of processing operations to perform on an application-layer message; rewrite the first workflow data by separation of dependent update operations to result in creating rewritten workflow data; and store the rewritten workflow data in a data repository. Application gateway logic may be operable to receive one or more packets; construct a received message from one or more payloads of the packets; classify the received message to identify a particular workflow associated with the message; apply the particular workflow, using the rewritten workflow data, to the received message to result in identifying a destination application server and creating an outgoing message; send the outgoing message to the destination application server.

摘要： An apparatus comprises a parse circuit and an expression processor. Coupled to receive a document, the parse circuit is configured to parse the document and generate events corresponding to the parsing. Coupled to receive the events from the parse circuit, the expression processor is configured to apply nodes identified by the events to one or more expression trees derived from a plurality of expressions in a stylesheet. The expression processor identifies nodes that satisfy the expressions represented in the one or more expression trees as a result of applying the nodes to the one or more expression trees. A method is contemplated. Each expression in a stylesheet is characterized as evaluatable at one of a plurality of phases of applying the stylesheet to a document in a document transformation appliance. Each expression is applied to the document in the one of the plurality of phases determined in the characterizing.
