Problems solved by technology

[0011] It can be seen that because the existing data retransmission technology is to retransmit all lost packets, when the network bandwidth is tight, the retransmitted data will further occupy the network bandwidth, thereby increasing the burden on the network and aggravating network congestion.

[0045] refer to image 3 As shown, it is a flow chart of the second embodiment of the method for retransmitting data based on user customization according to the present invention, and the method includes the following steps:

[0046] Step 301: The user customizes the retransmission model, and according to the data or application scenarios that the user is interested in, specifies one or more of the parameters such as source address, user ID, and data category to formulate a retransmission model that meets the user's requirements;

[0047] Of course, the data to be retransmitted may also be set according to other parameter information, and the present invention does not limit the type of parameter information.

[0048] Step 302: the receiving end detects the packet loss rate for the received message;

[0049] Step 303: determine whether the packet loss rate is greater than the threshold, if yes, execute step 304; if not, execute step 308;

[0050] Step 304: Determine whether...

Abstract

The invention discloses data retransmission method and device. The method comprises the following steps of: presetting the parameter information of data to be retransmitted at a receiving end; detecting the packet loss rate of received message data at the receiving end; determining the data to be retransmitted according to the parameter information when the packet loss rate is judged to be greater than the preset packet loss rate threshold, extracting the identification information of the data to be retransmitted, sending the identification information to a transmitting end, and requesting data retransmission. In the invention, a user specifies the data requiring high quality transmission by providing a user customization mechanism, data retransmission is executed for the packet loss of the data, and the packet loss of other data is not concerned. Thus, the invention not only can ensure that a part of data requiring high quality transmission can be retransmitted after loss, but also can not aggravate network burden in wide range.

Description

technical field [0001] The present invention relates to the technical field of network communication transmission, and more specifically, to a data retransmission method and device. Background technique [0002] Signals such as audio transmitted in the network are transmitted using UDP (User Datagram Protocol, User Datagram Protocol) packets in consideration of timeliness and resource utilization. When data is transmitted in the network, packet loss will inevitably occur due to factors such as insufficient network bandwidth. Due to the unreliable characteristics of UDP transmission, when the audio quality is relatively high, it is necessary to perform a retransmission operation according to the packet loss of the message. [0003] Data retransmission technology is a method in which the receiving end issues a retransmission command after discovering packet loss, requiring the sending end to resend the lost data to ensure the integrity of data transmission. [0004] refer to...
