ITR: On a Virtual Laboratory for Network Engineering Educational Programs

EIA-0081761赵，威州工程实验站ITR：关于网络工程教育专业的虚拟实验室这项研究的主要目的是研究建立网络工程教育专业虚拟实验室所涉及的问题。与传统的教学实验室不同，拟议的虚拟实验室将不要求学生物理地出现在实验室中，而是通过远程网络连接进行实验，例如万维网。旨在证明这种虚拟实验室在很大程度上促进了IT工作者的培训：它将降低成本，提高设备利用率，并提高以实验为导向的IT课程的质量。该项目将侧重于解决对成功实施和运作这样一个虚拟实验室至关重要的技术挑战。将研究如何在实验期间为学生提供远程但实时访问设备的配置和调度技术。这些配置必须以高效和灵活的方式进行，以便大量的学生可以同时进行他们的实验。访问控制方法也将被调查，这些方法涉及对给予用户的网络组件的控制程度。将通过一系列已实施的演习来检验不同出入控制方法的有效性。我们的目标是建立一个虚拟实验室，允许教师选择操作系统支持、实验语义和网络支持的相互作用，以最适合学习环境。

EIA-0081761Zhao, WeiTexas Engineering Experiment StationITR: On a Virtual Laboratory for Network Engineering Educational ProgramsThe primary objective of this proposed research is to investigate issuesinvolved in building a virtual laboratory for network engineeringeducational programs. Different from a conventional teaching laboratory,the proposed virtual laboratory will not require students to physicallypresent in the laboratory rooms, rather they conduct their experiments viaremote network connections, such as the World Wide Web. The intent is todemonstrate that this kind of virtual laboratory facilitates the trainingof IT workers in a significant way: it will reduce the cost, increase thefacility utilization, and improve the quality of IT courses that areexperiment-oriented. This project will focus on addressing technicalchallenges that are critical for successful implementation and operation ofsuch a virtual laboratory. Configuration and scheduling techniques will bestudied that provide students with remote but real time access to theequipment during their experiments. These kinds of configurations must becarried out in an efficient and flexible manner so that a large number ofstudents can do their experiments simultaneously. Access control methodswill also be investigated that deal with the degree of control over networkcomponents given to the user. The efficacy of diverse access controlmethods will be examined over a range of implemented exercises. The aim isto build a virtual laboratory that allows an instructor to choose theinterplay of operating system support, experiment semantics, and networksupport to best suit the learning environment.
