Redesign Goal
Develop an end-to-end technology architecture that satisfies the following criteria:
" Provide flexible telemetry with bidirectional communications" for remote devices
" Give users comprehensive access to specific devices and" aggregated data / statistics
" Link all components in real-time environment
" Provide clear, modular path for expansion
" Scale gracefully

Results
" Real-time system allows system components to monitor and act on a huge variety of message types and sources.
" Reduction in server load: several HTTP requests per client per second became zero, as clients now simply register for server messages and wait.
" Reduced latency: legacy system “real-time” streaming had a 3-5 second delay, new design delay is only 400-500 ms end-to-end from device to server to user.
Example: Across The Years -‐ 24, 48, 72 Hours over New Years (125-‐250 par3cipants, ~200 "watchers" online) § Manual FTP text file to website every 2-‐3 hours § Programma3c FTP HTML page every hour § Programma3c connec3on to 3ming computer, upload latest data every 12 seconds
§ WebSocket upload immediately to website and browser
① Java program at race site • Connects to 3ming data source ("real world") • Connects to WebSocket Gateway as Java client • "Source of truth" for race data to the web
② WebSocket gateway • In the cloud (easily accessible to viewers) • Local database for race data storage • Supports publish/subscribe API (JMS) • Only one port needed to access/store data
③ End-‐user browser • Any browser back to IE6 • Connects to KWG as JavaScript client • Page built with JavaScript, JQuery, PHP
