Preparation of vehicle bulk data for high speed terahertz offloading
One example method includes collecting data concerning operation of a vehicle, and the collecting is performed by one or more sensors of the vehicle, storing the data in the data storage locally at the vehicle, automatically caching the stored data in the cache memory locally at the vehicle, and uploading the cached data to a node over a THz wireless link. The stored data may be automatically cached according to requirements specified in a data model, and the cached data may be prioritized for uploading according to requirements specified in the data model.
1. A method, comprising:
collecting data concerning operation of a vehicle, wherein the collecting is performed by one or more sensors of the vehicle;
storing the data in storage locally at the vehicle using a tiered storage approach in which any of the data that cannot initially be accommodated in a cache memory of the vehicle is stored in one or more SSDs of the vehicle, and any remaining data of the data that cannot be accommodated in the one or more SSDs is stored in one or more HDDs of the vehicle;
using a data model to categorize some of the data as critical, and to prioritize the critical data for uploading;
automatically caching some of the critical data in the cache memory locally at the vehicle according to the data model, wherein the cache memory is capable of matching a data transfer rate associated with a THz wireless link; and
uploading the critical cached data from the cache memory, before any of the other collected data, to a node over the THz wireless link.
2. The method as recited in claim 1 , wherein when the cache memory is empty, data from one of the one or more SSDs and/or one of the one or more HDDs is used to replenish the cache memory.
3. The method as recited in claim 1 , wherein the cached data is uploaded during a time window whose start time and length are calculated by a processor on the vehicle.
4. The method as recited in claim 1 , further comprising uploading the cached data to another vehicle.
5. The method as recited in claim 1 , wherein the cached data is uploaded to the node while the vehicle is in motion.
6. The method as recited in claim 1 , wherein the data model is modifiable by an operator of the vehicle.
7. The method as recited in claim 1 , wherein the cache memory is continuously replenished with portions of the collected data until all of the collected data has been uploaded.
8. A non-transitory storage medium having stored therein instructions that are executable by one or more hardware processors to perform operations comprising:
collecting data concerning operation of a vehicle, wherein the collecting is performed by one or more sensors of the vehicle;
storing the data in storage locally at the vehicle using a tiered storage approach in which any of the data that cannot initially be accommodated in a cache memory of the vehicle is stored in one or more SSDs of the vehicle, and any remaining data of the data that cannot be accommodated in the one or more SSDs is stored in one or more HDDs of the vehicle;
using a data model to categorize some of the data as critical, and to prioritize the critical data for uploading;
automatically caching some of the critical data in the cache memory locally at the vehicle according to the data model, wherein the cache memory is capable of matching a data transfer rate associated with a THz wireless link; and
uploading the critical cached data from the cache memory, before any of the other collected data, to a node over the THz wireless link.
9. The non-transitory storage medium as recited in claim 8 , wherein when the cache memory is empty, data from one of the one or more SSDs and/or one of the one or more HDDs is used to replenish the cache memory.
10. The non-transitory storage medium as recited in claim 8 , wherein the cached data is uploaded during a time window whose start time and length are calculated by a processor on the vehicle.
11. The non-transitory storage medium as recited in claim 8 , wherein the operations further comprise uploading the cached data to another vehicle.
12. The non-transitory storage medium as recited in claim 8 , wherein the cached data is uploaded to the node while the vehicle is in motion.
13. The non-transitory storage medium as recited in claim 8 , wherein the data model is modifiable by an operator of the vehicle.
14. The non-transitory storage medium as recited in claim 8 , wherein the cache memory is continuously replenished with portions of the collected data until all of the collected data has been uploaded.
15. A system, comprising:
one or more hardware processors;
data storage comprising one or more SSDs and one or more HDDs;
cache memory; and
a non-transitory storage medium having stored therein instructions that are executable by the one or more hardware processors to perform operations comprising:
collecting data concerning operation of a vehicle, wherein the collecting is performed by one or more sensors of the vehicle;
storing the data in storage locally at the vehicle using a tiered storage approach in which any of the data that cannot initially be accommodated in a cache memory of the vehicle is stored in the one or more SSDs of the vehicle, and any remaining data of the data that cannot be accommodated in the one or more SSDs is stored in the one or more HDDs of the vehicle;
using a data model to categorize some of the data as critical, and to prioritize the critical data for uploading;
automatically caching some of the critical data in the cache memory locally at the vehicle according to the data model, wherein the cache memory is capable of matching a data transfer rate associated with a THz wireless link; and
uploading the critical cached data from the cache memory, before any of the other collected data, to a node over the THz wireless link.
16. The system as recited in claim 15 , wherein the system is installed in the vehicle.
17. The system as recited in claim 15 , wherein the cached data is uploaded to the node while the vehicle is in motion.
18. The system as recited in 15 , wherein the cache memory is continuously replenished with portions of the collected data until all of the collected data has been uploaded.
19. The system as recited in claim 15 , wherein when the cache memory is empty, data from one of the one or more SSDs and/or one of the one or more HDDs is used to replenish the cache memory.
20. The system as recited in claim 15 , wherein the cached data is uploaded during a time window whose start time and length are calculated by one of the one or more hardware processors.
