Abstract
Systems, methods, and software described herein provide enhancements for managing quality of service for data communications on a satellite of a satellite platform. In one implementation, a satellite obtains a plurality of packets to be transmitted to a second system of the satellite platform. Once obtained, the satellite prioritizes the transmission of the plurality of packets based on a quality of service associated with each of the packets, and transmits the plurality of packets based on the prioritization.
Claims20
A method of operating a satellite of a satellite platform, the method comprising:
- determining a first quality of service level for at least execution of at least a virtual node on the satellite employed to capture sensor data;
- obtaining sensor data corresponding to an underlying object or region of interest;
- establishing a plurality of data packets comprising the sensor data to be transmitted to at least one other system of the satellite platform;
- allocating at least transmission resources of the satellite to at least the virtual node of the satellite based on the first quality of service level;
- determining a quality of service modification event associated with at least a location of the satellite in orbit corresponding to the underlying object or region of interest for which the sensor data has been obtained;
- in response to the quality of service modification event, allocating at least the transmission resources of the satellite to at least the virtual node based on a second quality of service level;
- determining at least a transmission prioritization for at least the plurality of data packets based on the second quality of service level associated with the location of the satellite in orbit;
- and
- transmitting the plurality of data packets based on the transmission prioritization.
6 more elements
A satellite comprising:
- one or more non-transitory computer readable storage media;
- a processing system operatively coupled to the one or more non-transitory computer readable storage media;
- and
- program instructions stored on the one or more non-transitory computer readable storage media to manage data packets communicated over the satellite that, when read and executed by the processing system, direct the processing system to at least:
- determine a first quality of service level for at least execution of at least a virtual node on the satellite employed to capture sensor data;
- obtain sensor data corresponding to an underlying object or region of interest;
- establish a plurality of data packets comprising the sensor data to be transmitted to at least one other system of a satellite platform, wherein the satellite platform comprises a plurality of satellites;
- allocate at least transmission resources of the satellite to at least the virtual node of the satellite based on the first quality of service level;
- determine a quality of service modification event associated with a location in orbit encountered by the satellite corresponding to the underlying object or region of interest for which the sensor data has been obtained;
- in response to the quality of service modification event, allocate at least the transmission resources of the satellite to at least the virtual node based on a second quality of service level;
- determine at least a transmission prioritization for at least the plurality of data packets based on the second quality of service level associated with the location in orbit for the plurality of data packets;
- and
- transmit the plurality of data packets based on the transmission prioritization.
