Problems solved by technology

However, the above method only considers the priority between different streaming media applications, and does not consider the quality of the transmission link between the server and the terminal where the streaming media application is installed
[0004] And there is no method for determining the quality of the transmission link based on the QUIC protocol in the prior art

Abstract

The invention discloses a method and device for determining the quality of a transmission link, which can determine the quality of the transmission link. A receiving end receives at least one QUIC data packet and a characteristic value of a load in each QUIC data packet sent by a sending end through a current transmission link, then a characteristic value of a load in each QUIC data packet in theat least one received QUIC data packet is determined, according to the received characteristic value of the load in each QUIC data packet and the characteristic value of the load in each QUIC data packet sent by the sending end, a target data packet in the QUIC data packets sent by the sending end is determined, so that the data packet of which the characteristic value of the load is the same as the characteristic value of the load in one QUIC data packet in the at least one QUIC data packet is determined, and thus the receiving end can determine the link quality parameter of the current transmission link and determine the quality of the current transmission link according to the parameter of the target data packet.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a method and device for determining the quality of a transmission link. Background technique [0002] Quick User Datagram Protocol (User Datagram Protocol, UDP) network connection (Quick UDP Internet Connection, QUIC) protocol supports fast connection, with low round-trip delay (round-trip time, RTT), forward error correction, multiplexing, etc. advantage. In view of the advantages of the QUIC protocol, audio and video transmission based on the QUIC protocol has become a current research hotspot. [0003] In the prior art, there is a QUIC protocol-based streaming media quality of experience (quality of experience, QoE) improvement method to provide users with better QoE. Specifically, multiple streaming media applications based on the QUIC protocol are classified according to priority in advance, and the server allocates relatively more bandwidth resource...
