Throughput of communication protocols for distributed systems under transferring a group of frames

It continues to be a hot topic how to increase the throughput of communication protocols in distributed system, which reflects in the emergence of new standards and the numerous research projects in this area. This article discusses one option to improve throughput of link layer protocol based on the sending the source of message of positive acknowledgment to receiver groups. The paper shows the definition of productivity and communication protocols, as well as the factors affecting throughput of channel layer protocols. The calculations determine the number of acknowledgment under the condition that the sender of the message will be the delivery acknowledgment guaranteed. The accuracy of the results is also confirmed by the results of the analytical and simulation in the Matlab environment.
