FIELD: engineering of multi-service networks, providing transmission of traffic of different types: data, video, speech, and, in particular, networks, utilizing various commutation algorithms. ^ SUBSTANCE: method for positioning statistical multiplexing during transfer of information between devices of network ending and commutation nodes includes receiving and recording channel data blocks during transfer, sorting received data blocks in accordance to given transfer directions, data blocks of constant and/or data blocks of alternating length are grouped, which are positioned in multiplexing intervals with header - identifier of data blocks and containing information for their later routing and/or commutation, and are transferred in accordance to transfer directions via network communication channel, and during receipt in network end devices and on each commutation node, data blocks, received from communication channel, are ungrouped in accordance to given transfer directions, while data blocks being received are sorted in accordance to given transfer directions and priorities for different sort of traffic, sorted data blocks depending on presence of free multiplexing intervals are accumulated in transfer buffer and traffic buffer for forming a queue for transferring data blocks, data blocks accumulated in traffic buffer are analyzed, on basis of results of analysis of accumulated data blocks, computation and generation of multiplexing intervals of alternating duration is performed, accumulated data blocks are grouped in generated multiplexing intervals of alternating duration and transferred in accordance to transfer directions via network communication channel, while multiplexing intervals of alternating duration are formed in such a way, that average duration of multiplexing interval, called base length of multiplexing interval, remains the same, while duration of base multiplexing interval is selected to be not less than time of transfer of data block of maximal duration. ^ EFFECT: increased efficiency of usage of channel resources, decreased jitter and abolished rigid synchronization between commutation nodes. ^ 15 cl, 9 dwg, 2 tbl, 1 app |
