AB  -            Implementing Telecommunication’s Switching and Routing          Laboratory Practices: Migration to a Distance Learning based                                  InstructionTraditional learning environment laboratory practices related to telecommunication laboratoriesare aimed to learn to program and interconnect a variety of switches, routers, firewallsappliances, VoIP phones and support equipment. These practices are typically pre-wired withinour laboratory facilities and students are required to work within the facilities as part of theirpractical experience. The need to be physically present at pre-scheduled hours with an instructor,limits the possibilities of many non-traditional students wanting to take these courses. The needto design viable alternatives that allow students to access laboratory facilities remotely withoutlosing most of the educational objectives, typically achieved in a face-to-face environment, isincreasing by the day.This paper propose a solution already implemented and tested in order to move a traditionallytaught routing and switching telecommunication course, to an ONLINE based instruction. Thedesign requires remote access authentication to the VMWare View system which is composed ofthree servers: The secure server, the composer server and the administrative server. Theseservers have been virtualized and reside on the hardware allocated for the project. The VMWareView system is housed on a cluster of eight Sun Server X6250 blades. Each blade serves as aVMWare ESX 5.0 host. Within the administrative server, a pool of virtual computers is created.Any student with internet access enrolled in the course can authenticate to the VMWare Viewsecure server which checks them for password validity and for access authorization. Once accessis granted, the user is assigned to a random virtual computer in the pool. Upon logging off, thevirtual computer that the user was logged into will be deleted and re-copied from the snapshot sothat the next user who logs in to it will get a clean copy and will not be able to access theprevious user’s data.Once student is granted access to a virtual machine it can first perform hundreds of simulationswith virtual routers, switches, terminals and with all current telecommunication protocols withinthe virtual server environment using the NetSim® for CCNA V9 simulation software. Once thestudents gets proficient with a simulated laboratory environment, which mimics the real set-up ofthe laboratory facilities, a specially created secure proxy-firewalled network allows then to takecontrol of the laboratory real facilities, which are prewired for the specific practice in place.Students then are allowed to manage and program real switches, routers, VoIP phones, firewalland perform laboratory practices as if they were inside the laboratory. In case they needassistance, instructors with remote access to the facilities can be reached online within thelaboratory hours.
