The Models Of The Redundant Transmission Through The Aggregated Channels

Abstract

Abstract-The paper deals with the distributed systems with channel aggregation. The aim of the work is to investigate the possibilities of increasing the efficiency of the exchange through the aggregated channels while making the redundant transmissions of the packet copies that are critical to the timing of error-free delivery to an addressee.The study of the exchange effectiveness is based on the simulation modeling in the AnyLogic 7 environment.We consider the variants of the exchange arrangement when the set of the channels is divided into groups with the implementation of the single multiple access procedure for each group or without division into groups with implementation of the single multiple access procedure separately for each channel. The efficiency of the redundant transmissions of the packet copies through the aggregated channels is shown for the different variants of the queue organization, multiple access and channel grouping. The limits of the redundant transmission expediency of packets that are critical to the timing of the error-free delivery through the aggregated channels are determined.
