摘要： A method of generating a query plan for accessing a database, comprising: receiving (S10) one or more electronic queries from a database client; and determining (S20) whether the received one or more queries form a part of a query pattern comprising a repeating sequence of a plurality of queries by determining whether the received one or more queries match a part of the sequence of queries. If the received one or more queries are determined to form a part of the query pattern, the method further comprises generating (S30) a query plan for executing one or more queries in the sequence that match the received one or more queries, and a query that is subsequent to the matching one or more queries in the sequence.

摘要： Apparatus for performing packet classification of data packets belonging to a packet flow through a packet data network. The apparatus comprises an ingress interface for receiving packets of said packet flow, and an active filter for disturbing one or more of said packets or for otherwise disturbing a characteristic of said flow. An egress interface is provided for sending the packets including a disturbance towards a destination. A monitor is also provided for monitoring said packet flow and/or one or more associated packet flows received by the apparatus to detect subsequent reactions in the flow/s to the disturbance, while a flow classifier is provided for attempting to classify the flow into one of a set of defined classes according to a detected reaction.

摘要： A data scheme and protocol (DSP) adapter which translates communications received from one or more application servers (FEs) into corresponding communications understandable by one or more repositories (BEs). The DSP adapter comprises an interface unit which receives a FE query from a FE. The DSP adapter comprises a processing unit which determines an FE query pattern fulfilled by the FE query and checks whether the FE query pattern exists for the FE query in an accessible memory. Where the FE query pattern does not exist in the accessible memory, the processing unit transforms the FE query pattern into a corresponding BE query pattern. Where the FE query pattern exists in the accessible memory, the processing unit obtains the corresponding BE query pattern from the accessible memory. A method for translating at a data scheme and protocol (DSP) adapter communications received from one or more application servers (FEs) into corresponding communications understandable by one or more repositories (BEs).
