Use of end-to-end acknowledgment in Mil-Std-188-220 A extended networks

Abstract

The OPNET simulation software developed by MIL3 has been used to construct a very detailed model of the Mil-Std-188-220 A network protocol executing over a SINCGARS radio net operating in packet mode. The intranet relay function provided by this protocol has included a transport layer like acknowledgment for ensuring reliable transmission across multiple relayers within a network. The intranet end-to-end (ETE) acknowledgment is in addition to any reliability provided by the link layer. This paper examines the performance of multi-hop relay networks using different combinations of network layer and link layer reliability functions. The paper presents recommendations for the use of the ETE acknowledgment based on throughput, delay, and completion percentage.
