In general, the architecture consists of three layers:  Iaas(IEC), PaaS(Tars), SaaS(AR/VR Application).

Use Cases

In general, there are multiple use cases for AR VR itemized below.  For Release 2, we focus on building the infrastructure and virtual classroom application (Highlighted in dark purple color).

After successfully deploy the virtual classroom application, the following virtual classroom is waiting for you. Enjoy!

Overall Architecture

The whole architecture, shown below, consists of two parts: the front end and the backend.

Optimization

To address the requirements of time-critical Application, some optimizations are itemized below:

...

• Lightweight framework
  1. To make Tars can be well deployed on the edge computing platform, we make the framework pluggable. The customer plugin the pluggable components when we really need it. Unnecessary components can be avoided.
  2. Rewrite some functions(like scale-out, monitor and so on) to reduce CPU consumption. 
  3. Orchestrate no-urgent functions(like monitor data calculation and so on) from edge to DC(or higher level edge). Reduce resource consumption.
• IEC Optimization: IEC uses Calico as the main container networking solution which uses a pure IP networking fabric to deliver high-performance Kubernetes networking, and its policy engine enforces developer intent for high-level network policy management. Together, Calico and Kubernetes provide a secure, cloud-native platform that can scale your infrastructure to support hundreds of thousands of users. Calico CNI also supports multi-cni plugin. In this way, users can customize their own edge systems.

Main Progresses for Release 2

Release 2 is the first release for IEC Type 4. So everything is new.

Build Of Materials (BOM) / Hardware requirements

For R2, we deploy IEC in Tencent Cloud for Release.  The detailed hardware is itemized below:
