Howard A Seid, Albert Lespagnol: Virtual private network. Alcatel Data Networks, Ware Fressola Van Der Sluys & Adolphson, June 16, 1998: US05768271 (164 worldwide citation)

In a packet switching (packet-based) network, such as a frame relay (FR) network, which includes network resources made up of networked elements and customer premises equipment interconnected by one or more physical paths, a Virtual Private Network (VPN) is built above the underlying packet-based ne ...

In a packet-based communications network (100), a virtual connection is established between a source node (102a) and a destination node (102b), which may traverse one or more intermediate nodes (105). During the flow of packets along the virtual connection in a forward direction, from the source nod ...

Albert Lespagnol, Jean Paul Quinouis: Frame switching relay for asynchronous digital network. France Telecom, Jacobson Price Holman & Stern, August 17, 1993: US05237564 (91 worldwide citation)

A frame switching relay switches frames between input and output paths by multiplexing of the paths at frame cell level. A frame is divided into cells having a constant number of bits, whereas the frames are of variable length. The switching relay only retransmits frames that have been completely wr ...

Jean Paul Quinquis, Michel Servel, Albert Lespagnol: Buffer queue write pointer control circuit notably for self-channelling packet time-division switching system. Etat Francais represente par le Ministre des Postes et Telecommunications et de l Espace, Lowe Price LeBlanc Becker & Shur, June 12, 1990: US04933932 (40 worldwide citation)

The circuit embodying the invention comprises a pointer memory memorizing J=16 decremented write pointers associated with J=16 buffer queues. A channelling word supplied conjointly to incoming data and indicating the buffer queue in which this data is to be written, addresses the corresponding decre ...

Albert Lespagnol, Jacques Y Kerberenes: Method and system of control of flow of data packets. L etat Francais Represente par le Ministre des PTT Centre National d Etudes des Telecommunications, Laff Whitesel Conte & Saret, January 23, 1990: US04896316 (36 worldwide citation)

The packet flow of each virtual circuit is measured and compared to an allocated average value. At each transmission authorization request (DAE'), when found to be less than the average value, a positive difference brings about an authorization to transmit and is translated into a right to transmit ...
