Method for controlling traffic based on clock signals and delay
A recently granted patent (Publication Number: US11659215B2) describes a method for controlling traffic between an originating server and multiple second nodes in a communication system. The method involves receiving a local clock signal from the originating server in each second node and determining a unidirectional delay between the originating server and the second node based on the received local clock signal and the local clock signal of the second node. The determined unidirectional delay is then monitored to control traffic between the originating server and the second node.
The method includes various techniques for controlling traffic. This can involve requesting Adaptive Bitrate (ABR) adjustments, rerouting of traffic, or selective retransmission based on the determined unidirectional delay. The originating server can distribute multiple data channels with different ABR levels to the second nodes, and the traffic control can involve adjusting the number of distributed channels and ABR levels.
The unidirectional delay is determined in the direction of the content stream. The method also includes transferring the local clock signal of the second node back to the originating server and selectively employing two-way transfer mode to synchronize the local clock of the originating server and the second node. The two-way transfer mode can be activated during predetermined time intervals or with a predetermined frequency or rate.
Additionally, the method involves determining the round-trip time (RTT) between the originating server and the second node based on the determined unidirectional delay or the local clock signals. Timer settings for retransmission of Negative-acknowledgements (NACKs) can be determined to recover from lost NACKs or retransmitted data.
The method can also be used to detect overload in a network system or assess the performance of the network system in the absence of overload based on the determined unidirectional delay.
The patent also describes a node in a communication system and a non-transitory computer-readable storage medium that can execute the method described in the claims.
Overall, this patent presents a method for controlling traffic between an originating server and multiple second nodes in a communication system, offering various techniques for traffic control and synchronization between nodes.
