Abstract
Method and system for communicating over an open communication network; communication data blocks are provided with a code word with a cyclic numbering for successive blocks to be able to place received block in the correct sequence. By detecting the missing data block and/or an acknowledgement control block with a number added to the data block restoring procedures are preformed. After a successful restoring procedure the number of the originally missed block and or the acknowledgement control block are left out the cyclic numbering for a time at least equal to the warranted maximum packet lifetime in the network.
