Abstract: In a client-server environment, a method and system are disclosed for granting transparency to the compulsory gateway of an IP network versus client applications run by the end-users connected on the IP network. When client applications have to access, on request of the end-users, server applications beyond the compulsory gateway this latter acts on behalf of them to access the requested remote resources eventually, relaying data between client and server applications. This is achieved without requiring any personalization on client end thus, guarantees that since gateway is becoming transparent to client applications all improvements and modifications brought to the IP network actually fully benefit to all end-users.

Abstract: Data transmission system including a proxy connected to the Internet network and at least a content server to which a user can gain access by the intermediary of the proxy, the proxy being associated with authentication means adapted to perform form-based authentication of the user when receiving a user request for Internet resources therefrom and wherein the proxy transmits the user request to the content server which sends back a response to the proxy. The authentication means comprise a Single Sign-On (SSO) server adapted to obtain a login form from the content server when receiving the user request from the proxy, to fill the login form by using the credentials associated with the user and to send back the filled login form thereby, playing the role of the user regarding the content server, so that the content server can provide the requested information after authentication of the user.

Abstract: A system operating in the intelligent peripheral servers (IP) of an intelligent network, allowing a telephone user to access the service applications (SLPs) of the peripheral server it is connected to or other service applications (SLPs) located on a remote server (SCP) of the intelligent network. The system comprises a programming interface to develop service applications operating in the intelligent peripheral and a handler modifying the standardized communication protocol between the intelligent peripheral server and the remote servers. The service applications located in the servers (IP and SCP) are developed using the programming interface, the handler being adapted to each intelligent network protocol such as ITU/ETSI or BELLCORE or WIN standards used in direct mode, through a direct network communication between the remote and intelligent peripheral servers or a communication through the central exchange (SSP) of the switched telephone network to which the telephone user is connected.

Abstract: A flow control mechanism for use in a high speed packet switching network where calls are multiplexed on network trunks with each connection using a reserved amount of the total bandwidth. Data terminal equipments access the network via access nodes. Each access node includes a Leaky Bucket component which maintains a refillable token pool. Each time an incoming packet is received by the leaky bucket component, the number of available tokens is compared to two predetermined threshold values. If the number of tokens is less than the low threshold, acknowledgments of received packets are stopped, inducing an interruption of packets transmitted by the emitting terminals. Interrupting packet transmission will lead to a regeneration of the number of tokens in the token pool. If the number of tokens reaches the high threshold, acknowledgments are again generated to restore packet transmissions.

Interrupting packet transmission will lead to a regeneration of the number of tokens in the token pool.

Abstract: A preventive X.25 flow control mechanism for use in a high speed packet switching network where calls are multiplexed on network trunks with each connection using a reserved amount of the total bandwidth. X.25 data terminal equipments access the network via access nodes. Each access node includes a Leaky Bucket component which maintains a refillable token pool. Each time an incoming packet is received by the leaky bucket component, the number of available tokens is compared to two predetermined threshold values. If the number of tokens is less than the low threshold, acknowledgments of received packets are stopped, inducing an interruption of packets transmitted by the emitting attached X.25 terminals. Interrupting packet transmission will lead to a regeneration of the number of tokens in the token pool. If the number of tokens reaches the high threshold, acknowledgments are again generated to restore packet transmissions.
