A method for establishing an Internet access by using a WLAN protocol from a mobile client station, via an access point to be chosen from a set of identified access points, includes: providing a general database of the identified access points with connection information; requesting Internet access using the protocol, successively moving through browsing through, selecting, associating, authenticating and configuring; establishing the Internet access of the mobile client station via the selected access point. Before and independently of the requesting the Internet access, connection information of at least a portion of the access points of the general database is downloaded into an onboard database of the mobile client station. The browsing through and selecting are carried out based on the downloaded connection information, without soliciting the general database and the identified access points.

Method and system for establishing an internet access by using a wireless local area network communication protocol from a mobile client station

The invention concerns a digital processing system fed by at least one filter having three possible states resulting from one or more conditions on one or more protocol attributes, specified for a semantic stream. Each protocol attribute is specified by an ordered sequence of protocol names used in the semantic stream and a parameter name carried by a protocol whereof the name is indicated in the ordered sequence of protocol names. The digital processing device comprises a filtering engine which applies the filter on the communication data until the data provide protocol attribute values wherefrom results a valid or invalid state of the filter and an action motor which triggers the action when the state of the filter is valid.

A method for protocol identification by recognizing determinative data among data transmitted through a detected connection using lists of explicit and implicit son protocols associated with each protocol. The kernel of an information system associates to each detected connection a data structure arranged so that it comprises an ordered sequence of the protocol names. The kernel builds the data structure by retrieving the son protocol names in the list associated to the last protocol name of said ordered sequence, the son protocol name for which the associated self identification mechanism recognizes determinant data among transmitted data by adding the retrieved son protocol name to the end of the sequence and by restarting to retrieve the son protocol name for which the associated self identification mechanism recognizes determinant data among transmitted data.

An explicit rate algorithm is disclosed for use in an end-to-end closed loop flow control algorithm for an ATM network which carries at least constant bit rate (CBR) traffic, variable bit rate (VBR) traffic and adjustable bit rate (ABR) traffic. The algorithm determines how much additional bandwidth is available for ABR traffic on an output link from a node and produces an explicit rate variable that can be forwarded to a source for the ABR traffic. Both the maximum and minimum bandwidths already reserved for all connections on the output link are determined. A single reserved bandwidth value is chosen within the range defined by the maximum and minimum reserved bandwidth values. The current utilization of the ABR input buffer for the node is also determined. The explicit rate variable is generated as a function of the link capacity, the reserved bandwidth value and the current utilization of the ABR input buffer. The explicit rate variable is written into a resource management cell which is routed through the network to the ABR traffic source. The explicit rate variable is intended to change the input rate of the ABR source to utilize more of the ABR input buffer.
