The following describes a software environment applied by the method for setting delay provided by the embodiment of the present invention, taking an android operating system as an example.
Fig. 1 is a schematic diagram of an architecture of an android operating system according to an embodiment of the present invention. In fig. 1, the architecture of the android operating system includes 4 layers, which are respectively: an application layer, an application framework layer, a system runtime layer, and a kernel layer (specifically, a Linux kernel layer).
The application program layer comprises various application programs (including system application programs and third-party application programs) in an android operating system.
The application framework layer is a framework of the application, and a developer can develop some applications based on the application framework layer under the condition of complying with the development principle of the framework of the application.
The system runtime layer includes libraries (also called system libraries) and android operating system runtime environments. The library mainly provides various resources required by the android operating system. The android operating system running environment is used for providing a software environment for the android operating system.
The kernel layer is an operating system layer of an android operating system and belongs to the bottommost layer of an android operating system software layer. The kernel layer provides kernel system services and hardware-related drivers for the android operating system based on the Linux kernel.
Taking an android operating system as an example, in the embodiment of the present invention, a developer may develop a software program for implementing the method for setting a delay provided in the embodiment of the present invention based on the system architecture of the android operating system shown in fig. 1, so that the method for setting a delay may operate based on the android operating system shown in fig. 1. Namely, the processor or the terminal device can implement the method for setting the delay provided by the embodiment of the invention by running the software program in the android operating system.
The method for setting delay according to the embodiment of the present invention is described below with reference to a flowchart of the method for setting delay shown in fig. 2, and as shown in fig. 2, the method for setting delay according to the embodiment of the present invention includes steps 201 to 203:
step 201: and under the condition that the first equipment establishes a link with the second equipment, the first equipment acquires the target data packet.
Step 202: the first device determines a target delay corresponding to a packet type of the target packet.
Step 203: and the first equipment sets the chain breaking delay of the link according to the target delay.
In this embodiment of the present invention, the aforementioned link disconnection delay of the link between the first device and the second device is used to indicate a delay of disconnecting the link between the first device and the second device, that is, when the link disconnection delay times out, the link is disconnected.
In an embodiment of the present invention, the packet types include at least one of the following: transmission Control Protocol (TCP), User Datagram Protocol (UDP), and Control Message Protocol (ICMP). For example, when the packet type of the destination packet is TCP, it indicates that the destination packet is a packet encapsulated based on TCP, when the packet type of the destination packet is UDP, it indicates that the destination packet is a packet encapsulated based on UDP, and when the packet type of the destination packet is TCP, it indicates that the destination packet is a packet encapsulated based on ICMP.
In the embodiment of the invention, different data packet types correspond to different broken link delays. For example, because the UDP packet and the ICMP packet have high requirements on real-time performance and continuity of data, if the link-breaking delay is too short, the link may be reestablished in the transmission of the subsequent packet, and therefore, for the UDP packet and the ICMP packet, a longer link-breaking delay needs to be set.
In an embodiment of the present invention, the target data packet is: and a data packet transmitted on a link between the first device and the second device.
In this embodiment of the present invention, the process of the first device acquiring the target data packet may include: the first device receives the destination data packet from the second device, or the first device sends the destination data packet to the second device.
Optionally, in this embodiment of the present invention, the first device may determine, based on a preset first delay correspondence table, a target delay corresponding to a packet type of the target packet. Wherein, the first delay corresponding relation table includes: x packet types and Y delays, one packet type corresponding to at least one delay, X, Y being a positive integer and Y being greater than or equal to X. Illustratively, after acquiring the target data packet, the first device searches for the target delay corresponding to the data packet type of the target data packet in the first delay correspondence table by using the data packet type of the target data packet as an index.
Optionally, in this embodiment of the present invention, when the data packet type of the target data packet is TCP, the step 202 specifically includes the following steps:
step 202 a: and the first equipment determines the target delay corresponding to the target identifier in the target data packet from the M first delays corresponding to the TCP type.
The target mark is used for indicating the type of the broken link delay of the target data packet; the type of chain-breaking delay comprises at least one of the following: chain breakage is delayed in advance; m is a positive integer.
Illustratively, the above-mentioned types of chain-breaking delay include at least one of: a first type, a second type, a third type, a fourth type, and a fifth type. The first type is used for indicating that the chain breaking is postponed when data are transmitted subsequently, the second type is used for indicating that the chain breaking is advanced when no data are transmitted subsequently, the third type is used for indicating that the chain breaking is advanced when data response exists, the fourth type is used for indicating that the chain breaking time is distinguished according to the size of a data packet in the data transmission process, and the fifth type is used for indicating that the chain breaking is advanced when the chain breaking is forcibly performed.
In one example, the above target identifier is carried in the TCP FLAG field. The target identifier may be the following identifiers in the TCP FLAG field: establishing a connection SYN identifier, closing a connection FIN identifier, responding an ACK identifier, delivering a message to an application layer PSH identifier, a connection resetting RST identifier and an urgent pointer URG identifier, wherein the SYN indicates a first type; the FIN mentioned above indicates a second type; the ACK described above indicates a third type; the above PSH indicates a fourth type; the URG mentioned above indicates a fifth type.
In one example, when determining the target delay corresponding to the target identifier in the target data packet from the M first delays, the first device may determine the target delay corresponding to the target identifier in the target data packet based on a preset second delay correspondence table. Wherein, the delay corresponding relation table includes: m marks and M first delays, wherein the M marks comprise the target marks, and one mark corresponds to one first delay. For example, after obtaining the first delay corresponding to the packet type of the target packet, the first device uses the target identifier in the target packet as an index, and finds the first delay corresponding to the target identifier (i.e., the target delay) in the second delay correspondence table.
In another example, the first device may directly determine the target delay corresponding to the target identifier based on a preset third delay correspondence table. The third delay correspondence table is composed of the first delay correspondence table and the second delay correspondence table.
Optionally, in this embodiment of the present invention, if the target data packet is another data packet except the first data packet, before step 203, the method further includes the following steps:
step 203 a: and under the condition of acquiring the first data packet, the first equipment sets a broken link delay timer.
The timing time of the broken link delay timer is as follows: the delay time corresponding to the packet type of the first packet. The first packet is the first packet with certain data in sequence.
Further, in combination with the step 203a, the step 203 specifically includes the following steps:
step 203 b: and the first equipment updates the timing time of the delay timer according to the target delay.
Further, the step 203b specifically includes the following steps:
step 203b 1: the first device reads the remaining time of the delink delay timer.
Step 203b 2: and if the residual time is less than the target delay, the first equipment updates the target delay to the timing time of the broken link delay timer.
Further, the step 203b further includes the following steps:
step 203b 3: and if the remaining time is greater than or equal to the target delay, the first equipment does not update the timing time of the broken link delay timer.
It should be noted that the timing time in the above-mentioned delink delay timer may be a positive time or a negative time.
Illustratively, a link is established between a first device and a second device for data transmission, when the first device acquires a first data packet, the first device directly sets a broken link delay timer, the timing time of the broken link delay timer is the delay time corresponding to the data packet type of the first data packet, when the first device acquires other data packets except the first data packet, the first device directly reads the real-time of the broken link delay timer to acquire the remaining time of the broken link delay timer, compares the remaining time with the delays corresponding to the data packet types of the other data packets, and sets the timing time of the broken link delay timer according to the comparison result. For example, when the remaining time is less than the delay corresponding to the packet type of the other packet, the delay is used as the timing time of the broken link delay timer. And when the remaining time is greater than or equal to the delay corresponding to the data packet type of the other data packets, not updating the timing time of the broken link delay timer.
It should be noted that, when the delink delay timer expires, the first device is instructed to disconnect from the second device.
In the method for setting a delay provided in the embodiment of the present invention, when a link is established between a first device and a second device, after the first device acquires a target data packet, a link-breaking delay of the link between the first device and the second device may be set according to the target delay corresponding to a data packet type of the target data packet, that is, different link-breaking delays are set for data packets of different data packet types, so that when a terminal device communicates with a network device, the power consumption of the whole terminal device or the data transmission process is not affected due to improper setting of the link-breaking delay.

Optionally, the setting module 303 is further configured to: if the target data packet acquired by the acquisition module 301 is a data packet other than the first data packet, setting a broken link delay timer when the first data packet is acquired; the timing time of the broken link delay timer is as follows: the delay time corresponding to the packet type of the first packet; the setting module 303 is specifically configured to: according to the target delay determined by the determining module 302, the timing time of the broken link delay timer is updated.

In the first device provided in the embodiment of the present invention, when the first device establishes a link with the second device, after the first device acquires the target data packet, the link-breaking delay of the link between the first device and the second device may be set according to the target delay corresponding to the data packet type of the target data packet, that is, different link-breaking delays are set for data packets of different data packet types, so as to avoid that, when a terminal device communicates with a network device, the overall power consumption of the terminal device or the data transmission process is affected due to improper setting of the link-breaking delay.
