A method and apparatus for providing for segmentation, reassembly and inverse multiplexing of variable sized packets and ATM cells over satellite and wireless links. Variable sized packets are divided into segments having a size equal to that of an ATM cell and are arranged in a segmentation and reassembly (SAR) frame having in its overhead an indication as to the length and unique identity of the frame, each segment also having a header that uniquely identifies the segment, the destination and the origination of the packet from which the segment originates, A terminal id is also used to identify the unit, site and control group from which the segment originates so that the information can be transmitted on the basis of available bandwidth on demand.
L'invention concerne un procédé et un appareil permettant la segmentation, le réassemblage et le multiplexage inverse de paquets de tailles variées et de cellules MTA dans des liaisons par satellite et sans fil. Des paquets de tailles variées sont divisés en segments de taille égale à celle d'une cellule MTA et sont disposés dans une trame de segmentation et de réassemblage (SAR) possédant dans son en-tête une indication sur la longueur et l'identité unique de la trame, chaque segment possédant également un en-tête qui identifie de manière unique le segment, la destination et l'origine du paquet dont provient le segment. Une identification du terminal permet également d'identifier l'unité, le site et le groupe de commande dont provient le segment de sorte que les informations peuvent être transmises sur la base de la largeur de bande disponible à la demande.
