分布式触觉虚拟环境中触觉数据的有效传输是一个新的研究领域，对底层网络提出了许多挑战。这些应用中反射力的传输有可能改变人类与机器交互和相互通信的方式。未来的互联网将不得不承载多种DHVE类型的业务，并且现在已经确定，由当前IP网络提供的尽力而为服务不足以满足这些类型的应用的需求，这些应用需要来自网络的特定服务质量（QoS）。这里介绍的工作的目的是，以减少多个DHVE网络连接产生的流量。所采取的方法是开发一个模拟模型的DHVE交通的经验测量的基础上。同步和异步的真实的世界DHVE流量进行分析，量化和导入到网络模拟。概率密度函数（PDF）模型，随后推导出DHVE系统中的每种类型的流量。结果表明，网络仿真模型与物理网络相比，可以用来生成一个可扩展的触觉网络模型，其中多个DHVE连接可以检查。
The effective transmission of haptic data in Distributed Haptic Virtual Environment (DHVEs) is a new research area which presents a number of challenges to the underlying network. The transmission of reflected force in these applications has the potential to change the way humans interact with machines and communicate with each other. The future Internet will have to carry multiple DHVE type traffic and it is now established that the best effort service offered by current IP networks is insufficient to meet the needs of these type of applications, which require specific Quality of Service (QoS) from network. The aim of the work presented here is to characterise the traffic generated by multiple DHVE network connections. The approach taken is to develop a simulation model of DHVE traffic based on empirical measurements. Both synchronous and asynchronous real world DHVE traffic is analyzed, quantified and imported into a network simulation. Probability Density Function (PDF) models are subsequently derived for each type of traffic in the DHVE system. The results show the network simulation model compares favourably with the physical network, and can be used to generate a scalable haptic network model where multiple DHVE connections may be examined.
