ITR: On a Virtual Laboratory for Network Engineering Educational Programs

[参考译文]赵伟德克萨斯州工程实验站itr：网络工程教育计划的虚拟实验室本研究的主要目的是探讨建立网络工程教育计划的虚拟实验室所涉及的问题。与传统的教学实验室不同，拟议中的虚拟实验室将不要求学生实际出现在实验室房间中，而是他们通过远程网络连接（如万维网）进行实验。目的是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，增加设施利用率，并提高以实验为导向的IT课程的质量。该项目将专注于解决对成功实施和运营这样一个虚拟实验室至关重要的技术挑战。将研究配置和调度技术，为学生在实验期间提供远程但实时的设备访问。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实验。访问控制方法也将被研究，处理对网络组件给予用户的控制程度。各种访问控制方法的有效性将在一系列实施的演习中进行检查。目的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，以最适合的学习环境。

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.
