Embodiment Construction

[0051] In order to clearly describe the technical solutions of the embodiments of the present application, in the embodiments of the present application, words such as "first" and "second" are used to distinguish the same or similar items with basically the same function and effect. For example, the first value and the second value are only used to distinguish different values, and their sequence is not limited. Those skilled in the art can understand that words such as "first" and "second" do not limit the number and execution order, and words such as "first" and "second" do not necessarily limit the difference.

[0052] It should be noted that, in the embodiments of the present application, words such as "exemplary" or "for example" are used as examples, illustrations or descriptions. Any embodiment or design solution described as "exemplary" or "for example" in the embodiments of the present application shall not be interpreted as being more preferred or more advantageous t...

Abstract

The embodiment of the invention provides a data packet processing method and device, and relates to the technical field of communication, and the method comprises the steps that an upper computer transmits a target data packet to a lower computer; the upper computer determines that the first feedback signaling of the lower computer is not received according to a preset condition; the upper computer sends a continuous signaling to the lower computer; the upper computer receives a second feedback signaling of the lower computer; and the upper computer sends the target data packet to the lower computer. The first feedback signaling is the feedback signaling of the lower computer in response to the data packet of the upper computer; the second feedback signaling is the feedback signaling of the lower computer in response to the signaling of the upper computer; the continuous signaling is used for indicating continuous sending of the target data packet. Thus, in the data packet transmission process, if data transmission interruption is caused by abnormal communication, the data packet which is not successfully sent can be sent again, all data does not need to be transmitted again, and therefore the data transmission efficiency can be improved.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a data packet processing method and device. Background technique [0002] With the continuous development of mobile communication technology, various electronic devices such as intelligent transportation equipment, smart home equipment, and robots are gradually entering people's daily life. In order to meet the various needs of users for the use of electronic equipment, the update speed of various electronic equipment are gradually accelerating, and it is especially necessary to download and upgrade the application program for the electronic device. For example, in the field of automotive electronics technology, including: various types of vehicles such as intelligent networked vehicles, self-driving vehicles or new energy vehicles, electronic control units (electronic control units, ECUs) contained in various types of vehicles, such as on-board electronic E...
