Detailed Description
It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
In the related art, in order to avoid network congestion and overload, the normal operation of various applications is ensured, and good network service quality is provided for users, and the use of bandwidth is generally controlled by setting a network speed limit value. The network speed limit value specifies the bandwidth resources that are most available to an application or user in the network for a certain period of time. However, when the network traffic suddenly changes, the network traffic exceeds the bandwidth specified by the network speed limit value, and all the data packets cannot be processed and forwarded in time, so that the phenomena of buffer overflow, packet loss, queuing and the like are caused. These problems can lead to unstable transmission times of data packets, which can lead to network jitter.
In order to solve the above-mentioned drawbacks in the related art, the present invention provides a network speed limiting method, which mainly comprises the following steps:
determining the quantity of data packets to be forwarded according to a network speed limit value, acquiring the data packets to be forwarded which are consistent with the quantity, determining the total forwarding time of forwarding the data packets to be forwarded according to the total length of the data packets to be forwarded and the network speed limit value, determining the unit transmission time corresponding to the data packets to be forwarded according to the total forwarding time and the quantity, determining the sending sequence of the data packets to be forwarded according to the length of the data packets to be forwarded and the unit length of the unit transmission time, and forwarding the data packets to be forwarded according to the sending sequence of the data packets to be forwarded. According to the network speed limit value and the length of the data packet to be forwarded, the transmission sequence of the data packet to be forwarded is reasonably planned, so that the bandwidth in each unit transmission time is utilized to the greatest extent, the bandwidth specified by the network speed limit value is not exceeded, and the network jitter phenomenon is avoided.
In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
Referring to fig. 1, in an embodiment of the network speed limiting method of the present invention, the network speed limiting method includes the steps of:
step S10: determining the quantity of data packets to be forwarded according to a network speed limit value, and acquiring the data packets to be forwarded which are consistent with the quantity;
the network speed limit value specifies the bandwidth resources that are most available to an application or user in the network for a certain period of time. For example, the network speed limit value is 200 megabits/second, which indicates that the user can only transmit 200 megabits of data per second at most, and if the data transmitted per second exceeds 200 megabits, the conditions such as data loss, data delay increase, network congestion and the like may be caused, so that the network jitter phenomenon occurs.
In this embodiment, the execution body is a mobile terminal. Such as a mobile phone, a computer, and a server, which is not particularly limited in this embodiment. When receiving the data packet to be forwarded, the mobile terminal stores the data packet to be forwarded into a queue to be forwarded, and forwards the data packet to be forwarded in the queue to be forwarded to the target equipment in sequence according to the first-in first-out rule. The target device may be any device, and this embodiment is not particularly limited.
Optionally, to avoid the occurrence of network jitter, bandwidth resources are utilized to the greatest extent. The invention receives the average length of the data packet and the network speed limit value obtained by calculation, divides the network speed limit value by the average length of the data packet, thereby determining the quantity of the data packet to be forwarded, and obtaining the data packet to be forwarded which is consistent with the quantity from a queue to be forwarded. It can be understood that the result obtained by dividing the network speed limit value by the average length of the data packets represents the maximum number of data packets to be forwarded that can be sent per second by the mobile terminal when the network speed limit value is satisfied.
Step S20: determining the total forwarding time for forwarding the data packet to be forwarded according to the total length of the data packet to be forwarded and the network speed limit value;
in this embodiment, because the lengths of the actually obtained data packets to be forwarded are different from the average lengths, the lengths of the data packets to be forwarded are further obtained, the total length of all the data packets to be forwarded is counted, and the total forwarding time required for actually forwarding all the data packets to be forwarded is determined according to the total length and the network speed limit value. It will be appreciated that the total length of the total forwarding time, determined according to the network speed limit, can accommodate the amount of data equal to the total length of the data packets to be forwarded.
Optionally, the total forwarding time of the data packet to be forwarded=the total length of the data packet to be forwarded/the network speed limit value. Total forwarding time total length of the amount of data can be accommodated = network speed limit/total forwarding time.
Step S30: determining unit transmission time corresponding to the data packet to be forwarded according to the total forwarding time and the number;
in the present embodiment, unit transmission time=total forwarding time/preset number. The total forwarding time is divided into parts which are consistent with the number of the data packets to be forwarded, and the unit transmission time corresponding to each part is the same.
It should be noted that, since the forwarding order of the data packets to be forwarded is fixed, and the unit transmission time is consistent with the number of the data packets to be forwarded, the unit transmission time of each data packet to be forwarded is fixed.
Alternatively, each data packet to be forwarded may be allocated to each unit transmission time according to the forwarding order of the data packets to be forwarded.
For example, the total forwarding time is 1.5 seconds, and the number of packets to be forwarded is 5, so the unit transmission time corresponding to the packets to be forwarded is 1.5/5=0.3 seconds. Thus dividing the total forwarding time into 5 equal parts, and the unit transmission time corresponding to each equal part is 0.3S. I.e. the total forwarding time is divided into five equal parts of 0-0.3S, 0.3-0.6S, 0.6-0.9S, 0.9-1.2S and 1.2-1.5S. And then distributing each data packet to be forwarded to the corresponding unit transmission time according to the forwarding sequence of the data packet to be forwarded. For example, the first data packet to be forwarded is allocated to a unit transmission time of 0-0.3S, the second data packet to be forwarded is allocated to a unit transmission time of 0.3-0.6S, and so on, which will not be repeated in this embodiment.
Optionally, each data packet to be forwarded may be identified in advance according to the forwarding sequence of the data packet to be forwarded, and each unit transmission time may be identified according to the time sequence of each unit transmission time, so that when the data packet to be forwarded is allocated, the data packet to be forwarded may be directly allocated to the unit transmission time having the same identification as the data packet to be forwarded, so as to quickly determine the sending sequence of the data packet to be forwarded.
For example, after the data packets to be forwarded are acquired, according to the forwarding sequence of the data packets to be forwarded, the identifiers of the data packets to be forwarded are determined to be 1, 2, 3, 4 and 5 respectively, and the data packets to be forwarded with the identifiers 1 to 5 are sequentially forwarded during forwarding. After the unit transmission time of the data packet to be forwarded is determined, according to the time sequence of the unit transmission time, the identification of 0-0.3S is 1, the identification of 0.3-0.6S is 2, the identification of 0.6-0.9S is 3, the identification of 0.9-1.2S is 4, and the identification of 1.2-1.5S is 5. And when the transmission sequence is determined, directly distributing the data packet to be forwarded to the unit transmission time with the same identification as the data packet to obtain the transmission sequence.
Step S40: determining a transmission sequence of the data packet to be forwarded according to the length of the data packet to be forwarded and the unit length of the unit transmission time;
the unit length of each unit transmission time capable of accommodating the data amount is the same, and after the data packets to be forwarded are distributed to each unit transmission time, certain unit lengths of the data packets to be forwarded exceed the unit length of the unit transmission time, and certain unit lengths of the data packets to be forwarded are lower than the unit length of the unit transmission time, if the data packets to be forwarded are distributed to the corresponding unit transmission time, the waste of bandwidth resources is caused.
In this embodiment, unit length of unit transmission time = network speed limit value. According to the length of the data packet to be forwarded and the unit length of the unit transmission time, the invention determines the target position of each data packet to be forwarded in the unit transmission time, thereby obtaining a transmission sequence. The length of the time occupied by the target position is equal to the length of the data packet to be forwarded, so that bandwidth resources are utilized to the greatest extent, the bandwidth specified by the network speed limit value is not exceeded, and the network jitter phenomenon is avoided.
Optionally, when the length of the data packet to be forwarded is greater than the length accommodated in the unit transmission time, the remaining time of the unit transmission time corresponding to the previous and/or the next data packet to be forwarded is occupied, and the remaining time and the unit transmission time corresponding to the data packet to be forwarded are taken as the target position of the data packet to be forwarded, so that the time occupied by the target position can accommodate the length of the data packet to be forwarded without exceeding the bandwidth specified by the network speed limit value, thereby avoiding the occurrence of the network jitter phenomenon.
Optionally, when the length of the data packet to be forwarded is smaller than the length accommodated in the unit transmission time, the corresponding position of the unit transmission time is inserted according to the length of the data packet to be forwarded, and the remaining time of the unit transmission time is left as the next data packet to be forwarded for use, or the remaining time is emptied, which is not specifically limited in this embodiment.
Step S50: and forwarding the data packet to be forwarded according to the sending sequence of the data packet to be forwarded.
In this embodiment, the present invention determines the duty ratio of the unit transmission time according to the ratio of the length of the data packet to be forwarded in each unit transmission time to the unit length of the unit transmission time, and then forwards the data packet to be forwarded according to the duty ratio of each unit transmission time in the transmission sequence.
Optionally, according to the duty ratio, the unused time in each unit transmission time can be determined, so that when the data packet to be forwarded in the unit transmission time is forwarded, the unused time in the unit transmission time is emptied according to the duty ratio, so as to ease the load of the network, avoid the loss of the data packet, and improve the stability and reliability of the network.
In the technical scheme provided by the embodiment, the number of the data packets to be forwarded is determined according to the network speed limit value, the data packets to be forwarded which are consistent with the number are obtained, then the total forwarding time for forwarding the data packets to be forwarded is determined according to the total length of the data packets to be forwarded and the network speed limit value, the unit transmission time corresponding to the data packets to be forwarded is determined according to the total forwarding time and the number, the sending sequence of the data packets to be forwarded is determined according to the length of the data packets to be forwarded and the unit length of the unit transmission time, and the data packets to be forwarded are forwarded according to the sending sequence of the data packets to be forwarded. According to the network speed limit value and the length of the data packet to be forwarded, the transmission sequence of the data packet to be forwarded is reasonably planned, so that the bandwidth in each unit transmission time is utilized to the greatest extent, the bandwidth specified by the network speed limit value is not exceeded, and the network jitter phenomenon is avoided.
Referring to fig. 2, in the second embodiment, based on the first embodiment, the step S40 includes:
step S41: determining a target data packet to be forwarded, wherein the length of the data packet to be forwarded is greater than the unit length of the unit transmission time;
in this embodiment, the length of each data packet to be forwarded is obtained, and the length of the data packet to be forwarded is compared with the unit length of the unit transmission time, so as to determine the target data packet to be forwarded, where the length of the data packet to be forwarded is greater than the unit length of the unit transmission time.
Step S42: determining a target position of the target forwarding data packet in the sending sequence according to the forwarding sequence and the target length of the target forwarding data packet, and inserting the target forwarding data packet into the target position;
in this embodiment, according to the forwarding sequence of the target data packet to be forwarded, the target unit transmission time corresponding to the target data packet to be forwarded is determined. And then forward operation is carried out on the front-end to-be-forwarded data packet of the target to-be-forwarded data packet or backward operation is carried out on the rear-end to-be-forwarded data packet of the target to-be-forwarded data packet, so that whether the front-end or rear-end of the target to-be-forwarded data packet has residual time or not is determined, if the residual time exists, the residual time and the target unit transmission time are used as target positions of the target to-be-forwarded data packet, the condition that the target to-be-forwarded data packet occupies transmission time of a plurality of to-be-forwarded data packets at the same time is avoided, the target to-be-forwarded data packet is split into a plurality of parts to be transmitted during forwarding, and data loss is easy to cause in the transmission process.
Step S43: and taking the unit transmission time corresponding to the forwarding sequence of the rest data packets to be forwarded as the position of the rest data packets to be forwarded in the sending sequence, and inserting the rest data packets to be forwarded into the position to obtain the sending sequence.
In this embodiment, after determining the target positions of all the target data packets to be forwarded, determining the corresponding target unit transmission time according to the forwarding sequence of the remaining data packets to be forwarded, so as to directly insert the remaining data packets to be forwarded into the corresponding positions of the target unit transmission time, thereby obtaining the transmission sequence of the data packets to be forwarded.
It can be understood that, because the target data packet to be forwarded occupies a part of the transmission time of the previous unit or occupies a part of the transmission time of the next unit, when the data packet to be forwarded of the previous unit is inserted, the part of the time occupied by the target data packet to be forwarded is automatically avoided, and overlapping among the data packets to be forwarded is avoided, thereby causing phenomena such as network unevenness, jitter, and the like.
In the technical solution provided in this embodiment, the transmission sequence is obtained by determining a target to-be-forwarded data packet with a length greater than a unit length of a unit transmission time of the to-be-forwarded data packet, determining a target position of the target to-be-forwarded data packet in the transmission sequence according to a forwarding sequence of the target to-be-forwarded data packet and the target length, inserting the target to-be-forwarded data packet into the target position, using the unit transmission time corresponding to the forwarding sequence of the remaining to-be-forwarded data packet as a position of the remaining to-be-forwarded data packet in the transmission sequence, and inserting the remaining to-be-forwarded data packet into the position. The method has the advantages that the target position of the target data packet to be forwarded with the length longer than the unit transmission time is preferentially determined, the target data packet to be forwarded is prevented from occupying excessive transmission time of the data packet to be forwarded at one time, the target data packet to be forwarded is prevented from being split into a plurality of parts to be transmitted during forwarding, and data loss is easy to cause in the transmission process.
Referring to fig. 3, in a third embodiment, based on any of the above embodiments, the step S42 includes:
step S421: determining a target unit transmission time corresponding to the target data packet to be forwarded according to the forwarding sequence of the target data packet to be forwarded;
step S422: if the forwarding sequence of the target data packet to be forwarded is smaller than a preset threshold, forward operation is carried out on the preamble data packet to be forwarded of the target data packet to be forwarded, and whether the preamble of the target data packet to be forwarded has first remaining time is determined, wherein the preamble data packet to be forwarded is the data packet to be forwarded of which the forwarding sequence is earlier than the forwarding sequence of the target data packet to be forwarded, and the preset threshold is half of the number;
in this embodiment, forward operation refers to pre-positioning a data packet to be forwarded with a preamble, that is, determining, in advance, a position of each data packet to be forwarded with a preamble in a transmission sequence according to a forwarding sequence of the data packet to be forwarded with the preamble, so as to determine whether a first remaining time exists in the preamble of the data packet to be forwarded with the preamble. In order to improve the calculation efficiency, if the forwarding sequence of the target data packets to be forwarded is smaller than a preset threshold value, the sequence of the target data packets to be forwarded is characterized as being earlier, the number of preceding data packets of the target data packets to be forwarded is smaller than the number of subsequent data packets to be forwarded, and at this time, forward operation can be preferentially performed on the target data packets to be forwarded.
When there are a plurality of target to-be-forwarded data packets, in the process of sequentially determining the target positions corresponding to the target to-be-forwarded data packets according to the forwarding sequence of the target to-be-forwarded data packets, if the first target to-be-forwarded data packet exists in the preamble to-be-forwarded data packet of the currently determined target to-be-forwarded data packet, the target positions of the first target to-be-forwarded data packet are already determined, so that forward operation is only required to be performed on the preamble to-be-forwarded data packet of the first target to-be-forwarded data packet after the forwarding sequence, and forward operation is not required to be performed on all the preamble to-be-forwarded data packets, thereby rapidly determining the target positions of the target to-be-forwarded data packets.
Optionally, the number of occupied unit transmission time can be determined according to the number of the data packets to be forwarded, so as to calculate the total unit transmission time occupied by the data packets to be forwarded, and calculate the total length of the preamble corresponding to the total unit transmission time according to the network speed limit value. And then the length of each preamble data packet to be forwarded is obtained, and the total length corresponding to the preamble data packet to be forwarded is determined. And when the total length of the preamble is larger than the corresponding total length of the data packet to be forwarded, the first residual time is characterized to exist, so that the first residual time is determined according to the difference value between the total length of the preamble and the total length of the data packet to be forwarded. It should be noted that, during the forward operation, the arrangement of the data packets to be forwarded in the preamble is forward arrangement, that is, the data packets to be forwarded in the preamble are allocated from the starting point of the unit transmission time.
It can be understood that total unit transmission time = unit transmission time x number of data packets to be forwarded by the preamble; total preamble length corresponding to total unit transmission time = network speed limit value; the total length corresponding to the data packets to be forwarded by the preamble is the sum of the lengths of the data packets to be forwarded by the preamble.
Step S423: and if the first residual time exists and the total length accommodated by the first residual time and the target unit transmission time is greater than or equal to the target length of the target data packet to be forwarded, taking the first residual time and the target unit transmission time as the target position of the target data packet to be forwarded, and inserting the target data packet to be forwarded into the target position.
In this embodiment, if there is a first remaining time and the total length of the first remaining time and the target unit transmission time is greater than or equal to the target length of the target data packet to be forwarded, the first remaining time and the target unit transmission time may be used as the target position of the target data packet to be forwarded, and the target data packet to be forwarded may be inserted into the target position.
Optionally, if the first remaining time does not exist, or the total length accommodated by the first remaining time and the target unit transmission time is smaller than the target length of the target data packet to be forwarded, performing backward operation on a subsequent data packet to be forwarded of the target data packet to be forwarded, and determining whether a second remaining time exists in the subsequent data packet to be forwarded of the target data packet to be forwarded, where the subsequent data packet to be forwarded is a data packet to be forwarded in a forwarding sequence of the target data packet to be forwarded after the forwarding sequence; and if the second residual time exists and the total length accommodated by the second residual time and the target unit transmission time is greater than or equal to the target length of the target data packet to be forwarded, taking the second residual time and the target unit transmission time as the target position of the target data packet to be forwarded, and inserting the target data packet to be forwarded into the target position.
In this embodiment, the backward operation refers to pre-positioning the to-be-forwarded data packets, that is, determining, in advance, the positions of each to-be-forwarded data packet in the transmission sequence according to the forwarding sequence of the to-be-forwarded data packets, so as to determine whether the second remaining time exists in the to-be-forwarded data packets. If the second remaining time exists and the total length of the second remaining time and the target unit transmission time is greater than or equal to the target length of the target data packet to be forwarded, the second remaining time and the target unit transmission time are used as target positions of the target data packet to be forwarded.
It should be noted that, during backward operation, the arrangement of the data packets to be forwarded in the backward direction is reverse arrangement, that is, the data packets to be forwarded in the backward direction are distributed from the end point of the unit transmission time, and the data packets to be forwarded in the backward direction are preset according to the reverse order of the data packets to be forwarded in the backward direction.
It can be understood that when the preamble of the target data packet to be forwarded is not available or the preamble is insufficient in remaining time, backward operation is performed on the data packet to be forwarded subsequent to the target data packet to be forwarded to determine whether the second remaining time exists in the sequence of the target data packet to be forwarded, so that the second remaining time and the target unit transmission time are used as the target position of the target data packet to be forwarded, the target data packet to be forwarded does not occupy the transmission time of a plurality of data packets to be forwarded at one time, the target data packet to be forwarded is prevented from being split into a plurality of parts to be sent during forwarding, and data loss is easy to cause in the transmission process. The subsequent data packets to be forwarded are the data packets to be forwarded in the forwarding sequence of the target data packets to be forwarded after the forwarding sequence.
Optionally, after the step of performing backward operation on the data packet to be forwarded subsequent to the target data packet to be forwarded to determine whether the second remaining time exists in the target data packet to be forwarded subsequent to the target data packet, the method further includes: if the second remaining time exists and the total length accommodated by the second remaining time and the target unit transmission time is smaller than the target length of the target data packet to be forwarded, the first remaining time, the second remaining time and the target unit transmission time are used as target positions of the target data packet to be forwarded, the target data packet to be forwarded is inserted into the target positions, and the purpose of ensuring that the transmission time of other data packets to be forwarded is enough without exceeding the bandwidth specified by the network speed limit value while ensuring that the target length of the target data packet to be forwarded is consistent with the length accommodated by the occupied transmission time is achieved. According to the network speed limiting method provided by the invention, even under the condition of encountering abrupt network traffic change, the forwarded data packet can be prevented from exceeding the bandwidth specified by the network speed limiting value, and the bandwidth resource can be utilized to the greatest extent.
In the technical solution provided in this embodiment, the target unit transmission time corresponding to the target to-be-forwarded data packet is determined according to the forwarding sequence of the target to-be-forwarded data packet, if the forwarding sequence of the target to-be-forwarded data packet is smaller than a preset threshold, forward operation is performed on the preamble to-be-forwarded data packet of the target to-be-forwarded data packet, and whether the first remaining time exists in the preamble of the target to-be-forwarded data packet is determined, where the preamble to-be-forwarded data packet is the to-be-forwarded data packet whose forwarding sequence precedes the forwarding sequence of the target to-be-forwarded data packet, the preset threshold is half of the number of to-be-forwarded data packets, and if the first remaining time exists, and the total length of the first remaining time and the target unit transmission time is greater than or equal to the target length of the target to-be-forwarded data packet, and the first remaining time and the target unit transmission time are used as the target position of the target to-be-forwarded data packet, and the target to-be-forwarded data packet is inserted into the target position. When the forwarding sequence of the target data packet to be forwarded is smaller than a preset threshold value, forward operation is performed on the preamble data packet to be forwarded to determine the target position corresponding to the target data packet to be forwarded, so that the calculation efficiency can be improved, the target data packet to be forwarded does not occupy the transmission time of a plurality of data packets to be forwarded at one time, the situation that the target data packet to be forwarded is split into a plurality of parts to be sent during forwarding is avoided, and data loss is easy to occur in the transmission process.
Referring to fig. 4, in a fourth embodiment, after step S421, based on any of the above embodiments, the method further includes:
step S424: if the target to-be-forwarded data packet is larger than the preset threshold value, performing backward operation on a subsequent to-be-forwarded data packet of the target to-be-forwarded data packet, and determining whether a third residual time exists in the subsequent to-be-forwarded data packet, wherein the subsequent to-be-forwarded data packet is a to-be-forwarded data packet in a forwarding sequence of the target to-be-forwarded data packet after the forwarding sequence;
in this embodiment, the backward operation refers to pre-positioning the to-be-forwarded data packets, that is, determining, in advance, the positions of each to-be-forwarded data packet in the transmission sequence according to the forwarding sequence of the to-be-forwarded data packets, so as to determine whether the second remaining time exists in the to-be-forwarded data packets. In order to improve the calculation efficiency, if the forwarding sequence of the target data packets to be forwarded is greater than a preset threshold, the sequence of the target data packets to be forwarded is characterized as being later, the number of the subsequent data packets of the target data packets to be forwarded is smaller than the number of the preceding data packets to be forwarded, and then the backward operation can be preferentially performed on the target data packets to be forwarded.
Optionally, the number of occupied unit transmission time can be determined according to the number of the data packets to be forwarded in the subsequent sequence, so as to calculate the total unit transmission time occupied by the data packets to be forwarded in the subsequent sequence, and calculate the total length of the subsequent sequence corresponding to the total unit transmission time according to the network speed limit value. And then acquiring the length of each subsequent data packet to be forwarded, and determining the corresponding total length of the subsequent data packets to be forwarded. And when the total length of the follow-up sequence is larger than the corresponding total length of the data packet to be forwarded, the existence of the third residual time is represented, so that the third residual time is determined according to the difference value between the total length of the follow-up sequence and the total length of the data packet to be forwarded. It should be noted that, during backward operation, the arrangement of the data packets to be forwarded in the subsequent sequence is reverse arrangement, that is, the data packets to be forwarded in the subsequent sequence are distributed from the end point of the unit transmission time, and the positions corresponding to the data packets to be forwarded in the subsequent sequence are sequentially determined according to the reverse sequence of the data packets to be forwarded in the subsequent sequence.
It can be understood that total unit transmission time = unit transmission time x number of subsequent data packets to be forwarded; total length of the subsequent sequence corresponding to the total unit transmission time=network speed limit value; the corresponding total length of the data packets to be forwarded in the follow-up sequence is the sum of the lengths of the data packets to be forwarded in the follow-up sequence.
Step S425: and if the third remaining time exists and the total length accommodated by the third remaining time and the target unit transmission time is greater than or equal to the target length of the target data packet to be forwarded, taking the third remaining time and the target unit transmission time as the target position of the target data packet to be forwarded, and inserting the target data packet to be forwarded into the target position.
In this embodiment, if the third remaining time exists and the total length of the third remaining time and the target unit transmission time is greater than or equal to the target length of the target data packet to be forwarded, the third remaining time and the target unit transmission time may be used as the target position of the target data packet to be forwarded, and the target data packet to be forwarded is inserted into the target position.
Optionally, if the third remaining time does not exist, or the total length accommodated by the third remaining time and the target unit transmission time is smaller than the target length of the target to-be-forwarded data packet, performing the forward operation on the to-be-forwarded data packet of the preamble of the target to-be-forwarded data packet, and determining whether the preamble of the target to-be-forwarded data packet has a fourth remaining time; and if the fourth remaining time exists and the total length accommodated by the fourth remaining time and the target unit transmission time is greater than or equal to the target length of the target data packet to be forwarded, taking the fourth remaining time and the target unit transmission time as the target position of the target data packet to be forwarded, and inserting the target data packet to be forwarded into the target position.
In this embodiment, when no remaining time is available in the subsequent sequence of the target data packet to be forwarded or the remaining time of the subsequent sequence is insufficient, forward operation is performed on the preamble data packet to be forwarded of the target data packet to determine whether a fourth remaining time exists in the preamble of the target data packet to be forwarded, so that the fourth remaining time and the target unit transmission time are used as the target position of the target data packet to be forwarded, so that the target data packet to be forwarded does not occupy the transmission time of a plurality of data packets to be forwarded at one time, and the problem that the target data packet to be forwarded is split into a plurality of parts to be sent during forwarding is avoided, and data loss is easy to cause in the transmission process. The subsequent data packets to be forwarded are the data packets to be forwarded in the forwarding sequence of the target data packets to be forwarded after the forwarding sequence.
Optionally, after the step of performing the forward operation on the data packet to be forwarded subsequent to the target data packet to be forwarded to determine whether the fourth remaining time exists in the preamble of the target data packet to be forwarded, the method further includes: and if the fourth remaining time exists and the total length accommodated by the fourth remaining time and the target unit transmission time is smaller than the target length of the target data packet to be forwarded, taking the third remaining time, the fourth remaining time and the target unit transmission time as the target position of the target data packet to be forwarded, and inserting the target data packet to be forwarded into the target position. The method aims at ensuring that the transmission time of other data packets to be forwarded is enough without exceeding the bandwidth specified by the network speed limit value while ensuring that the target length of the target data packet to be forwarded is consistent with the length accommodated by the occupied transmission time, thereby ensuring the smoothness of the network. According to the network speed limiting method provided by the invention, even under the condition of encountering abrupt network traffic change, the forwarded data packet can be prevented from exceeding the bandwidth specified by the network speed limiting value, and the bandwidth resource can be utilized to the greatest extent.
In the technical solution provided in this embodiment, the transmission time of the target unit corresponding to the target to-be-forwarded data packet is determined according to the forwarding sequence of the target to-be-forwarded data packet, if the target to-be-forwarded data packet is greater than the preset threshold, backward operation is performed on the subsequent to-be-forwarded data packet of the target to-be-forwarded data packet, and whether the third remaining time exists in the subsequent to-be-forwarded data packet, where the subsequent to-be-forwarded data packet is the to-be-forwarded data packet in the forwarding sequence of the target to-be-forwarded data packet after the forwarding sequence, and if the third remaining time exists, and the total length accommodated by the third remaining time and the target unit transmission time is greater than or equal to the target length of the target to-be-forwarded data packet, the third remaining time and the target unit transmission time are taken as the target position of the target to-be-forwarded data packet, and the target to-be-forwarded data packet is inserted into the target position, so that the calculation efficiency can be improved, and the target to-be-forwarded data packet does not occupy the transmission time of the multiple to-forwarded data packets at one time, and the target to be-forwarded data packet is prevented from being split into multiple parts to be transmitted during forwarding, and the data loss is easy to be caused in the transmission process.
