A method of processing a message in a communication network in which the message travels along a path which may be closed and which comprises a plurality of nodes. The message is constituted by a plurality of distinct information blocks of which certain may be destined for different nodes. The method is implemented in a node of the path and comprises the following steps: receiving the message; identifying in the message the information blocks destined for the node; processing the identified information blocks, with the creation as a consequence of at least one result data item; modifying the message by inclusion in it of the resulting item or items of data; and transmitting the message to the following node along the path. The invention also relates to a device adapted to implement the method.

A server computer sends, to a client computer, a service description document comprising information relating to a communication protocol used for exchanging messages, the service description document including a description of at least one functionality implemented by the communication protocol for an execution of the service over on the communication network using the protocol. The client computer analyzes the service description document by extracting the description of the functionalities implemented by the protocol from the service description document, verifying that each functionality is supported by the client computer of the communication network, and adding the protocol to a list of protocols usable for the execution of the service supplied by the server computer if all the functionalities associated with the communication protocol are supported by the client computer.

Method of proposing a service via a description document of such a service

An electronic document for describing a service proposed by a server computer of a communication network, comprises a first part adapted to describe messages exchanged between computers of the communication network and a second part adapted to comprise information relating to the transmission of messages over the communication network. The second part comprises two sub-parts, a first sub-part being adapted to comprise information on a format for representing messages and a second sub-part being adapted to comprise information on a communication protocol implemented for the transmission of the messages over the communication network.

Undoing a function requested by a first client station on a computer object stored on a server station of a communication network is provided. The execution of the function is adapted to manipulate the object from an earlier state to a manipulated state. The undoing is performed by receiving a request to undo the execution of the function. The earlier state of the manipulated object is obtained. Then, a response is sent to the first client station via the communication network, the response comprising a sum of money less than or equal to an execution cost associated with the function.

In predicting a quantity of a printing product necessary for printing a document, the document is stored in its entirety as digital data. Each page of the document is divided into bands of the digital data. From the digital data, a table of limited capacity is created, which describes at least part of a monochromatic component of one of the bands, with the monochromatic component corresponding to the printing product and each cell of the table representing at least a pixel. A number of switched-on pixels in the table is counted, with a switched-on pixel corresponding to a pixel for which a portion of the printing product must be ejected. Before enabling or demanding printing, a necessary quantity of the printing product is derived from a number of switched-on pixels corresponding to each band.
