FORGE ENABLING FIRE FACILITIES FOR THE E-LEARNING COMMUNITY
Diarmuid CollinsTrinity College Dublin, Ireland
Engineering and Experimentation• To understand the physics and engineering phenomena in wireless communications it is really important to reinforce theory with experimentation • The most effective way to demonstrate such physical properties and impairments of wireless signals is though radio laboratories
Lab ExperimentationPhysical Experimentation• Expensive, in particular for
low-budget institutions• Deploying and maintaining
experimental facilities is costly
• Developing cutting edge telecommunications technologies requires massive effort and budget
• Learners constrained by location and lab opening hours
• Underutilised
Online Experimentation• Offers remote access to
resources. • Not limited by time or
location• Empowers education by
enabling hands on experimentation
• FORGE focused on enhancing online telecommunications engineering by enabling remote experimentation
Future Internet Research and Experimentation (FIRE)
• The FIRE initiative is a European endeavor that promotes the creation of wide-scale federations of high performance testbed andexperimentation facilities for Internet and network-related research.
• €20 millioninvestment
E.g., Trinity College Dublin IRIS Testbed
FORGE
• Transforms FIRE testbeds into learning resources for education• Educational Layer over FIRE testbed facilities• Similar usage patterns between researcher & educational
learner• Resources are discovered, selected, reserved, provisioned (OS and Tools)• Experiment executed, controlled, monitored, results collected• Resources release.
FORGE: Hidden Complexity• Steps are Preconfigured and Automated
• Teacher – discover, select reserve, provision resources• Student – web based control and monitoring elements
• Supported by:• Widgets: micro-applications that perform a dedicated task• Adapters: Backend scripts that interact with FIRE testbed facility
FORGE Reference Architecture
List of Recommendations (1)• Reservation Mechanism
• Not available in all FIRE facilities• Hidden from learners• Integrates easily with widget + adapter
• Resource Scarcity • Multiple learners use same experimentation resource• Add multiplexing / queuing Layer• Lab has clear pre/post/transition states.• Maximum experiment duration • E.g., 1 minute, three learners – iMinds w-ilab.t testbed.
• Level of control• Software & hardware failure• Watchdog programs, scripts, instructions to support experiment recovery
List of Recommendations (2)• Multi-platform and easy integration to existing eLearning
platforms e.g., LMS, eBook, website, etc.• User interactions should be collected with Learning Analytics
• Inclusive of lab reservations, student interactions, and so forth• Learners should be uniquely identifiable (where possible)• Possible to spot cheaters or improper resource usage
• Introduce xAPI actions and verbs• E.g., User launched page• E,g., User answered question• Calculate action to action time spent by learners on course material
Challenges Encountered• Authentication
• Learning analytics - Who is using course, How, etc.• Security
• Block Anonymous access• Securely share resources among multiple FIRE accounts
• Standardised Reservation API• For reserving FIRE facilities
• Resource occupation: availability, scalability and scheduling• Reassessed and redesigned• Policy Strategy E.g., Best effort or premium• Queuing mechanism
• A fallback mechanism – in case testbed does not work• e.g., non-interactive version of lab
FORGE Contributions• Promoting Awareness of FIRE Testbed facilities• Methodology and process for using FIRE Testbed equipment• FORGEBox architecture – reference architecture• 18 courses (10 partner and 8 open call courses)
• WiFi, LTE, OFDM, IoT, TCP, HTTP, video streaming, and so forth. • Taught worldwide in over 10 countries• Over 2000 students• Contributed to Standardisation
• IEEE P1876: Standard for Networked Smart Learning Objects for Online Laboratories Working Group
• IEEE Actionable Data Book (ADB) for STEM Education• SIG on Remote labs and Online Experimentation
• Publications: 9 Published
