Abstract
The Very High Frequency (VHF) Digital Link (VDL) Mode 3 is based on a Time Division Multiple Access (TDMA) media access control (MAC) protocol. This MAC protocol incorporates priority queuing, slotted ALOHA, and polling by the ground station to handle channel contention and to achieve the speedy delivery of time critical ATC messages. This paper provides an overview of the VDL Mode 3 subnet simulation models in Optimized Network Engineering Tools (OPNET). Four different subnet models are available for the simulation of different system configurations, namely, 2V2D, 3V1D, 4D, and 3T. The usefulness of these simulation models is demonstrated by their capability in simulating a wide range of scenarios and protocol alternatives in dealing with various configurations, load factors, and protocol parameter settings.
VHF (Very High Frequency) Digital Link (VDL) Mode 3基于TDMA (Time Division Multiple Access)媒体访问控制(MAC)协议。该MAC协议结合了优先级队列、槽ALOHA和地面站的轮询，以处理信道争用并实现时间关键的ATC消息的快速传递。本文概述了优化网络工程工具(OPNET)中VDL模式3子网仿真模型。系统提供四种子网模型，分别为2V2D、3V1D、4D和3T，用于模拟不同的系统配置。这些仿真模型的有用性可以通过它们在处理各种配置、负载因素和协议参数设置时模拟各种场景和协议替代方案的能力来证明。
