...

Tencent has been deploying Tars on Connected Vehicle Blueprint and validating on IEC Type 4: AR/VR oriented Edge Stack for Integrated Edge Cloud (IEC) Blueprint Family.

Tars Microservice Framework

Tars is a high-performance microservice framework based on name service and Tars protocol, also integrated administration platform, and implemented hosting-service via the flexible schedule.

...

Nowadays it's used by hundreds of bussiness in Tencent, services that developed base on TAF run on 16 thousands of machines.

Connect Vehicle Blueprint

For Connected Vehicle Blueprint，Connected Vehicle Blueprint focuses on establishing an open-source MEC platform, which is the backbone for the V2X application. The blueprint can be deployed in multiple environments, including bare metal,  virtual machine as well as container.  

Sponsor Companies

Tencent, Arm, Intel, Nokia

Value Proposition

• Establish an open-source edge MEC platform on which each member company can develop its own v2x application.
• Contribute some use cases which help customers adopt V2X applications. 
• Find some members who can work together to figure out something big for the industry. 

Use Cases

From the use case perspective,  the following are the potential use cases. More is possible in the future.

• Accurate Location: Accuracy of location improved by over 10 times than today’s GPS system. Today’s GPS system is around 5-10 meters away from your reallocation, <1 meter is possible with the help of Connected Vehicle Blueprint. 
• Smarter Navigation: Real-time traffic information update, reduce the latency from minutes to seconds, figure out the most efficient way for drivers.
• Safe Drive Improvement: Figure out the potential risks which can NOT be seen by the driver.
• Reduce traffic violation: Let the driver understand the traffic rules in some specific area. For instance,  change the line prior to a narrow street, avoiding the opposite way drive in the one-way road, avoiding carpool lane when a single driver and so on.

Network Architecture

From the network architecture perspective,  the blueprint can be deployed in both 4G and 5G networks. Two key points should be paid special attention to.

...

• Grab the traffic/vehicle information and circulate the information to the edge;
• Different types of information are distributed to the corresponding application based on the configurable policy;
• The corresponding edge applications process the information in a very fast speed and figure out the suggested action items for drivers;
• The suggested action items are sent back to the driver via the network.

MEC Development Architecture

From the MEC deployment perspective,  the blueprint consists of three layers.

IEC Type 4: AR/VR oriented Edge Stack for Integrated Edge Cloud(IEC) Blueprint Family 

Integrated Edge Cloud(IEC) is an Akraino approved blueprint family and part of Akraino Edge Stack, which intends to develop a fully integrated edge infrastructure solution, and the project is completely focused on Edge Computing. This open-source software stack provides critical infrastructure to enable high performance, reduce latency, improve availability, lower operational overhead, provide scalability, address security needs, and improve fault management. The IEC project will address multiple edge use cases and industry, not just the Telco Industry. IEC intends to develop solution and support of carrier, provider, and the IoT networks.  

IEC Type 4 is focused on AR VR applications on the edge.  In general, the architecture consists of three layers:  Iaas(IEC Type2), PaaS(Tars), SaaS(AR/VR Application).

Sponsor Companies

Tencent, Arm, HTC, IBM, MobiledgeX, Visby, UC Irvine, Juniper, PSU, Orange

Value Proposition

• Establish an open-source edge infrastructure on which each member company can develop its own AR/VR application.
• Contribute some use cases which help customers adopt ARVR applications. 
• Find some members who can work together to figure out something big for the industry. 

Use Cases

The combination of IEC Type2 and Tars provides high performance and high availability infrastructure for AR/VR applications. The AR/VR application includes but not limited to operation guidance, virtual classroom, sports live, gaming as so on.

For Release 2, we focus on building the infrastructure and virtual classroom application (Highlighted in dark purple color). Virtual Classroom is a basic app that allows you to live a virtual reality experience simulating a classroom with teachers and students.

Architecture 

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