The vehicle needs to be continually connected, and offer a similar level of service to key applications regardless of the current network conditions. In order to ensure that key applications, such as Voice over IP (VoIP) and streaming multimedia, are able to function even on slow (2G & 3G) or congested networks, it is critical that Quality of Service (QoS) be applied to all network traffic passing through the vehicle. Utilizing the CVG platform to apply QoS provides the auto manufacturer, supplier, and the end consumer with the ability to ensure the applications which matter to them are given priority even in poor network conditions.
When passengers in the vehicle connect their wireless devices to the vehicle, they may generate more traffic than the network can currently handle. In order to maximize the experience for all users, including in-vehicle systems such as mapping and updates, it is necessary to implement application policy to prioritize key applications over secondary applications. This could be as simple as prioritizing in-vehicle systems over connected devices, or as advanced as determining that certain applications should only be allowed to run when the vehicle is connected to free Wi-Fi, to minimize the cost of performing network operations.
Quality of Service in action
This video demonstrates how the CVG prioritizes data traffic by application type when the overall network capacity is reduced when a network link (embedded LTE) goes away. The dashboard shows the CVG prioritizing FaceTime traffic (represented in purple) over Netflix traffic (represented in green). This ensures that the FaceTime call is not interrupted or impacted by the reduction in available bandwidth.
How it Works
The CVG provides Quality of Service (QoS) capabilities to ensure that important data sessions are not interrupted by lower priority data sessions. The auto manufacturer or supplier is able to configure policies that specify which high priority data sessions, such as phone calls (FaceTime), are given priority over lower priority sessions, such as Netflix. The CVG enables QoS by dynamically monitoring the capacity of each available link and adjusting the amount of bandwidth available to each active flow. This ensures that key applications are given priority when the network does not have enough capacity to process all data generated by passengers and vehicle.
