Predictive flow switching and application continuity in connected vehicle networks
The subject disclosure relates to ways to ensure vehicle network connectivity. In some aspects, a process of the technology includes steps for receiving local network measurement data including one or more connectivity metrics for at least one network provider (e.g., an ISP), and updating a geo-connectivity database using the received local network measurement data. In some aspects, the process can include additional steps for transmitting a geo-connectivity request to a remote Intelligent Vehicle Connectivity Analytics (IVCA) gateway, and for receiving a geo-connectivity reply from the remote IVCA gateway, the geo-connectivity reply including information regarding network availability for the at least one network provider along a vehicle path. Systems and machine-readable media are also provided.
1. An in-vehicle predictive multi-homing system, comprising:
a network interface coupled to one or more processors, the network interface configured for communication with at least one computer network; and
a computer-readable medium coupled to the one or more processors, the computer-readable medium comprising computer instructions stored therein, which when executed by the one or more processors, cause the one or more processors to perform operations comprising:
determining a first location of a vehicle;
computing first connectivity metrics for a first network provider at the first location;
computing second connectivity metrics for a second network provider at the first location;
computing a first path routing decision based on the first connectivity metrics and the second connectivity metrics;
updating a locally stored geo-connectivity database based on the on first connectivity metrics and the second connectivity metrics;
determine a second location of the vehicle;
computing updated first connectivity metrics for the first network provider at the second location;
computing updated second connectivity metrics for the second network provider at the second location;
comparing the updated first connectivity metrics for the first network provider with the updated second connectivity metrics for the second network provider to identify a preferred network provider at the second location of the vehicle; and
selecting the preferred network provider at the second location for one or more application flows associated with the vehicle.
2. The system of claim 1 , wherein the one or more processors are further configured to perform operations, comprising:
predicting a network connectivity path at a third location based on a route of the vehicle.
3. The system of claim 1 , wherein one or more processors are further configured to perform operations, comprising:
moving an application flow from the first network provider to the second network provider without disrupting the application continuity experience.
