Embodiment 1

[0071] A QUIC-based data transfer control method, such as figure 1 shown, including the following steps:

[0072] S1. When the terminal device and the content server establish a QUIC connection to transmit service data, the QUIC proxy server adopts the pre-built optimal ACK sending frequency acquisition model according to the wireless link status information fed back by the wireless access point to obtain the wireless access point The optimal ACK sending frequency corresponding to the fed back wireless link status information; the above ACK sending frequency is the inverse of the number of ACK-induced packets received cumulatively in the interval when the terminal device continuously sends two ACKs; the optimal ACK sending frequency includes making the terminal The device obtains the maximum effective throughput or the ACK sending frequency that optimizes other indicators (such as QoE or QoS, etc.).

[0073] Specifically, the optimal ACK sending frequency acquisition model is...

Abstract

The invention discloses a QUIC-based data transmission control method, system and device, and belongs to the technical field of communication, and the method comprises the following steps: S1, a QUIC proxy server obtains a model according to wireless link state information fed back by a wireless access point by adopting a pre-constructed optimal ACK sending frequency, and sends the optimal ACK sending frequency to a wireless access point; the optimal ACK sending frequency corresponding to the wireless link state information fed back by the wireless access point is obtained; s2, after the QUIC proxy server writes the reciprocal of the optimal ACK sending frequency into a corresponding byte bit of an ACKFREQUENCY frame of the QUIC, the ACKFREQUENCY frame is sent to the terminal equipment; s3, after the terminal equipment receives the ACKFREQUENCY frame, the ACK frame is sent to the content server according to a rule specified by the ACKFREQUENCY frame; s4, after receiving the ACK frame, the content server starts a Packing function in the QUIC connection to send service data to the terminal equipment; according to the invention, the optimal ACK sending frequency can be adaptively selected according to the wireless link state information, and the communication overhead is greatly reduced on the premise of ensuring the throughput.

Description

technical field [0001] The present invention belongs to the field of communication technologies, and more particularly, to a QUIC-based data transmission control method, system and device. Background technique [0002] Based on the User Datagram Protocol (UDP), Google proposes a Quick UDP Internet Connection (QUIC) technology. The key is "fast", which is compatible with the current wireless communication network that pursues high speed. QUIC also introduces TCP's acknowledgment mechanism to provide reliable transmission streams. Since the QUIC transmission bottom layer is encapsulated in UDP packet format and sending, receiving and processing UDP data may be CPU-intensive, when the frequency of ACK sending in the QUIC connection is too high, the CPU overhead is too high, reducing the power consumption of energy-constrained terminal devices. duration of use. In addition, for severely asymmetric links or wireless link scenarios where uplink and downlink contention exists, s...
