  • Method and device for transforming a series of data packets by means of data compression
    Patent number: 5774467
    Abstract: The invention relates to a method and device for converting data packets by coding or compression, source data packets being converted into transmission data packets. In order to achieve an optimal degree of filling of the transmission data packets, a data field of a transmission data packet according to the invention comprises only data of one logical channel. To this end, the compressed data of the logical channels are separately buffered in preferably parallel buffers. Reconstruction information is not incorporated in the data fields of the transmission data packets but, if necessary, is transmitted in advance. The invention is applied, in particular, in X.25 networks.
