Computers are linked together to form a network. Messages are sent over the links between the computers in compressed, segmented form, the size of the segments being appropriate to the transmission characteristics of the link. A message previously received or transmitted by a computer is stored in compressed and segmented form. If it is desired to forward or re-transmit this message, the segment size of the stored form is compared against the optimum segment size for the link over which the message is to be sent. If there is a close match, then the stored segmented, compressed message is retrieved for direct transmittal, without having to resegment or recompress the message.
Des ordinateurs sont reliés les uns aux autres pour former un réseau. Des messages sont transmis sur les liaisons entre ces ordinateurs sous forme comprimée et segmentée, la taille des segments étant appropriée aux caractéristiques de transmission des liaisons. Un message reçu ou transmis antérieurement par un ordinateur est stocké sous forme comprimée et segmentée. Si l'on désire acheminer ou retransmettre ce message, la taille des segments du message stocké est comparée à la taille de segment optimale pour la liaison sur laquelle ce message doit être transmis. Si ces tailles sont très voisines, le message comprimé et segmenté stocké est extrait en vue d'une transmission directe sans segmentation ou compression supplémentaire.
