Abstract: A server transmits an encoded game frame over a network to a respective client system as a set of packets. In response to transmitting the set of packets, the server determines a bandwidth estimate based on the size of the encoded game frame and the timing data associated with the transmitted set of packets. The server then compares the bandwidth estimate to a current video bitrate of the game stream being transmitted from the server to the respective client device. In response to the comparison indicating an underutilization of the network, the server increases the encoding bitrate. Further, in response to the comparison indication an overutilization of the network, the server decreases the encoding bitrate.

Abstract: Methods, systems, and apparatus are provided for fair data packet delivery. In some applications, such as financial exchanges, online gaming, and consensus protocols, having data received by each receiver at or near the same time can be just as important, if not more important, than achieving minimal latency. A system as described herein implements a hold-and-release of data packets on network interface controllers to ensure data packets are delivered to multiple receivers within tens of nanoseconds of one another. The system described can be implemented on a variety of different network devices with different built-in traffic shaping functionality. The hold and release is achieved by precise clocks in hardware, synchronized to deliver packets in a manner that reduces latency variation introduced in other end-to-end packet delivery systems. A fair data packet delivery system is achieved without relying on either software and its associated jitter, or system-specific notions of fairness.
