1. Ultimate Cloud Performance
1.1 High-speed User Experience
The RG-RCD Cloud Classroom Server Series adopts a number of innovative technologies, most notably the CDA (Cloud Desktop Acceleration) and the Appturbo technology, which integrate with Ruijie’s caching technology accumulated over the years to achieve mirror startup acceleration and IO acceleration. It significantly enhances the operating speed of cloud desktop startup and applications, offering better user experience than other products in the market. With the acceleration technology of the Cloud Classroom Servers, it only requires a few minutes for startup of up to 60 virtual machines. The startup and operating speed of common teaching software are enhanced by 200%, allowing students to enjoy high-speed cloud performance.
1.2 Optimized Video and Audio Playback
The innovative technology EST (Enhanced Stream Transmission) of the RG-RCD Cloud Classroom Server Series, developed by Ruijie’s R&D experts, is a virtual desktop transmission protocol that only requires very few resources to achieve high-performance data transfer. The protocol not only supports graphic display output, keyboard input, user interface device and cursor movement, but also specifically optimizes the quality of video decoding and high-quality audio restoration to present users with a lifelike high-resolution world.
Feature highlights of the high-performance EST include:
Accelerated 2D graphics rendering
Smart graphics compressions, which adjusts the graphics quality according to the network bandwidth
Intelligent end device recognition, featuring a smart adjustment of graphics quality according to the resources of end devices for the optimal user experience
Soft decoding of media stream to ensure a high-resolution playback of video and audio files (smooth playback of 480p videos)
Hard decoding of media stream to ensure a high-resolution playback of video and audio files (MJPEG and 1080p)
Hardware acceleration of the end device mouse
Re-direction of peripherals
Encryption of all data transmission through EST including graphics and other data to ensure security

1.3 Unprecedented Reliability
The Cloud Classroom Server Series took multiple advanced researches and customer surveys before its launch. This equipment completed a steady operation for more than 300 days at Ruijie Pressure Testing Laboratory, and also devised many application environments for customer testing in Beijing, Kunming, Guangzhou and Xi’ning, where the customers have once again strengthened the good reputation of Ruijie products and ensured a successful launch of the RG-RCD Cloud Classroom Server Series.
2. Intelligent Mirroring with One-key Selection
The innovative technology of the RG-RCD Cloud Classroom Server Series, IIM (Intelligent Image Management), reassembles and encapsulates different application software into different course images to provide flexible switching between different courses. The IIM can eliminate many performance problems incurred by installing too many applications, such as system bloat, slow operation, conflicts between software and heavy loads due to examination environment switching. Meanwhile, the virtual machine images will be restored automatically after class so that any modifications to the files will not be saved. This will protect the server against the invasion of computer virus without the need of complex configuration of Ghost or other recovery cards. IIM uses limited resources to create unlimited values, delivering high-quality mirroring.
2.2 Simplified Management
The RG-RCD Cloud Classroom Server Series assigns 3 different user interfaces to teacher, student and administrator. Students will obtain similar experience with Cloud Classroom as that with a physical server. Teachers can choose different course images and manage the classroom only with one button, significantly increasing teaching efficiency. Administrators can monitor the RG-RCD equipment anytime with a web browser, which clearly shows the visualized dynamics of CPU, memory, storage and network load.
2.3 One-key Control
The teacher system of the Cloud Classroom Server software adopts one-key management to eliminate teachers’ concern of the complex IT operation. Just with one button, a high-performance cloud teaching experience can be delivered. The administrator does not have to worry over the complicated commands. With the graphical user interface provided by the RG-RCD Cloud Classroom Server Series, you just need one button to create, edit and restore any graphics on the virtual machine. The RG-RCD Cloud Classroom Server Series enables users to enjoy the cloud experience with simple operations.
3. Outstanding Cost Efficiency
3.1 Advanced Design
Integrating the top-level processor, industrial-grade storage, mass memory and a powerful Cloud desktop software into a compact and robust all-in-one enclosure, the RG-RCD Cloud Classroom Server Series achieves a revolutionary innovation. With its brand new craftsmanship and outstanding innovative concept, the RG-RCD Cloud Classroom Server Series offers sparkling performance compacted in a small size.
3.2 Investment Protection
The RG-RCD Cloud Classroom Server Series adopts centralized computing and does not require any computing resources from the end devices. The old PCs, which traditionally would have been replaced due to the outdated features, can be used as display output to restore vivid images. The lifespan of the computer equipment will be prolonged thereby. The RG-RCD Cloud Classroom Server Series not only allows the old PCs to be reused, but also ensures high performance with lower resources. The scalability of the cloud technology largely eliminates the problems brought by upgrade or expansion. In collaboration with the Cloud Classroom end devices, the plug-and-play and simple deployment of the RG-RCD Cloud Classroom Server Series enables clients to expand the scale of computer classrooms at ease.
