Title: Innovations of Pascal Albert Lefebvre
Introduction
Pascal Albert Lefebvre is a notable inventor based in Brussels, Belgium. He has made significant contributions to the field of telecommunications, holding a total of 3 patents. His work focuses on enhancing network efficiency and managing data transmission effectively.
Latest Patents
Lefebvre's latest patents include a telecommunication network and a method for controlling such a network. This invention describes an ATM network where the downward data rate from the network to users exceeds the upward data rate from users to the network. The system utilizes multiplexers to establish connections that create virtual channels between users and the network, with these channels grouped into virtual paths. Each multiplexer near the user allows for variable bandwidth allocation to each downward virtual path, controlled by a call control mechanism in a switching node. Additionally, the upward virtual channels maintain a fixed bandwidth, ensuring a consistent quality of service for each downward virtual channel.
Another significant patent involves a method for managing multicast connections within a switching network. This method facilitates the transfer of data packets across multiple switching nodes, each equipped with switching node terminations (SNT). The internal header information (IHI) in the data packets identifies internal connections, while external header information (EHI) identifies outgoing connections. The method comprises three steps, including the association of a connection reference number (CRN) and a transfer type to the internal connection.
