The disclosed teachings provide methods and systems for efficient evaluation of XPath queries. In particular, the disclosed evaluation methods require only polynomial time with respect to the total size of an input XPath query and an input XML document. Crucial for the new methods is the notion of “context-value tables”. This idea can be further refined for queries in Core XPath and XSLT Patterns so as to yield even a linear time evaluation method. Moreover, the disclosed methods can be used for improving existing methods and systems for processing XPath expressions so to guarantee polynomial worst-case complexity.

The invention proposes a method and a unit for controlling the flow of at least one TCP connection between a sender and a receiver. The method is of the type which consists in controlling, at the level of a given multiplexing node through which TCP segments relevant to the connection pass, a window size parameter contained in acknowledgement segments sent back by the receiver. The method comprises the steps of:a) receiving an acknowledgement from the receiver on the up link (receiver to sender) of the connection at the level of said given multiplexing node;b) controlling a window size parameter contained in, said acknowledgement segment on the basis of the difference between, firstly, a first context value associated with the TCP connection, defined as being the sequence number of the last segment that was transmitted from said given multiplexing node on the down link (sender to receiver) of the connection, to which the length of said segment is added, and, secondly, the sequence number indicated in said acknowledgement segment;c) transmitting the acknowledgement segment to the sender the up link of the connection from said multiplexing node with the window size parameter thus controlled.

By using the method, the context modeling processes of different non-zero coefficients can be simultaneously performed, and parallel execution of multiple context modeling processes in the coding process is realized.
