Background
Network jitter refers to the delay variation of a data packet in the transmission process. Ideally, the delays of different packets during network transmission are the same.

Detailed Description
In order to make the technical solutions of the present application better understood, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In order to reduce network jitter, improve network service quality, and improve bandwidth utilization, an embodiment of the present application provides a data packet sending method, see fig. 1, which is a flowchart of a data packet sending method provided in an embodiment of the present application, and the method includes the following steps:
step S101, obtaining the actual bandwidth utilization rate according to the actual receiving flow of the data packet in the preset time period.
Within the field of communications, a single message data may be divided into a plurality of data blocks, referred to as data packets, which may be transmitted along the same or different paths in the network and reassembled at the destination to form the message data. When a data packet is transmitted over a long distance, it needs to pass through many intermediate transmission nodes, such as gateways or routers, and after receiving one or more data packets, the intermediate transmission nodes transmit the data packets to the next intermediate transmission node or destination node.
In this embodiment, the actual receiving traffic of the data packet in the preset time period is first obtained, and then the actual bandwidth utilization rate is obtained according to the actual receiving traffic and the preset time period.
The preset time period may be a time period customized by a user, and the preset time period may be continuous, for example, a continuous time period of 500ms, or discontinuous, for example, the first 100ms and the last 100ms of 500 ms.
The duration of the preset time period may be fixed, for example, a unit time (such as one millisecond, one second, one minute, etc.), or may be non-fixed, for example, the duration of a historical time period, where the historical time period is a time period used by the intermediate transmission node to transmit the data packet most recently. For example, the historical time period of the last data packet transmission by the intermediate transmission node is 600ms, that is, the preset time period may be set to 600 ms.
And after the preset time period is determined, acquiring the actual receiving flow of the data packet in the preset time period. In this embodiment of the application, the actual receiving traffic may be the number of the received packets in a preset time period, or may be the data amount in the received packets in the preset time period, where the unit of the data amount is, for example, a bit (bit), a megabit (Mbit, abbreviated as Mb), and the like. For example, assume that n packets are actually received within a preset time period T, where the data amount of the ith (i-1, 2, …, n) packet is ri(bit), therefore, the data volume actually received in the preset time period T is the sum of the data volumes of the received data packets, that is, the sum is
In this embodiment, after the actual received traffic within the preset time period is obtained, the actual bandwidth utilization rate is obtained according to the actual received traffic and the preset time period. Specifically, the actual bandwidth utilization may be a ratio of a packet transmission rate to a total bandwidth of the system, and the parameter reflects a bandwidth utilization condition. Too low bandwidth utilization may result in wasted system resources.
Taking the gateway as an example, assume that the actual received traffic is T within the preset time period with the duration of T
The total bandwidth of the gateway is W (bit/s), and the actual bandwidth utilization rate is
Step S102, if the actual bandwidth utilization is less than or equal to a preset bandwidth utilization, reducing the historical time period to a first target time period, so as to improve the receiving flow of the data packet in the preset time period.
Since the bandwidth utilization rate is a quantity reflecting the bandwidth utilization condition, and information resources are wasted due to too low bandwidth utilization rate, a preset bandwidth utilization rate can be preset, and when the actual bandwidth utilization rate is less than or equal to the preset bandwidth utilization rate, the bandwidth utilization rate is improved.
In some communication protocols (e.g., TCP protocol), when the delay of a packet received by a destination node is reduced, an originating node may increase the flow rate of the packet transmitted to the destination node per unit time through an intermediate transmission node. Based on the communication protocol, the present embodiment reduces the history time period to the first target time period in order to improve the bandwidth utilization. Wherein the historical time period is a time period adopted for recently transmitting the data packet. The bandwidth utilization rate in the historical time period is the same as the actual bandwidth utilization rate and is lower than the preset bandwidth utilization rate. The first target time period is a period used by the intermediate transmission node to transmit the data packet at present, that is, the time length of the first target time period is set, and the intermediate transmission node transmits the data packet once.
After the process of reducing the historical time period to the first target time periodThe waiting time of the data packet at the middle transmission node is reduced, so the time delay of the data packet received by the destination node is correspondingly reduced, the speed of sending the data packet by the initial node is improved according to the network transmission protocol, the receiving flow of the data packet in the preset time period is improved, and the bandwidth utilization formula is used
Under the condition that the total bandwidth of the gateway is not changed, the actual bandwidth utilization rate is correspondingly improved, so that the aim of improving the bandwidth utilization rate is fulfilled.
Taking the gateway in the above example as an example, assuming that the preset bandwidth utilization rate is 70%, when the actual bandwidth utilization rate α is not greater than 0.7 within the preset time period T, it indicates that the actual bandwidth utilization rate is low, the system bandwidth is not fully utilized, and the historical time period needs to be adjusted, that is, the historical time period is reduced to the first target time period, so as to increase the bandwidth utilization rate.
Step S103, using the first target time period as the current time period for sending the data packet, and sending the data packet received in the last first target time period.
After receiving the data packet, the intermediate transfer node may use the first target time period as a data packet transmission period, that is, a data packet received in a previous target time period is transmitted in a current target time period, for example, a data packet received in a jth (j ═ 1,2, …) target time period needs to be transmitted in a jth +1 target time period, where the number of transmitted data packets may be one or more.
For example, for a gateway, the target time period is 500ms, and it is assumed that two data packets are received within 0-500ms, specifically, a first data packet is received at 50ms, and a second data packet is received at 150ms, and the interval time is 100 ms. Then the two data packets are sent within 500ms-1000ms, and the second data packet is arranged behind the first data packet, so that the second data packet can be sent immediately after one data packet is sent, and the jitter phenomenon is effectively relieved.
In the prior art, a fixed time period is adopted to transmit data packets, although the jitter phenomenon is alleviated, when the flow of the data packets is small, the data packets are transmitted in the fixed time period, and when the number of the data packets to be transmitted in the time period is small, the bandwidth utilization rate is poor, so that the waste of network resources is caused.
According to the data packet sending method provided by the embodiment of the application, the actual bandwidth utilization rate is obtained according to the actual receiving flow of the data packet in the preset time period, if the actual bandwidth utilization rate is smaller than or equal to the preset bandwidth utilization rate, the historical time period is reduced to the first target time period so as to improve the receiving flow of the data packet in the preset time period, the historical time period is the time period adopted by the data packet which is sent recently, the first target time period is used as the current time period for sending the data packet, and the data packet received in the first target time period is sent. According to the communication protocol, when the time delay of the data packet received by the destination node is reduced, the flow of the data packet transmitted to the destination node in unit time is increased by the starting node through the intermediate transmission node. Therefore, the data packet sending method provided by the application can increase the data packet flow received by the intermediate transmission node in unit time by reducing the time period of sending the data packet by the intermediate transmission node, namely reducing the time delay of the data packet, thereby achieving the purpose of improving the bandwidth utilization rate.
Based on the foregoing embodiments, an embodiment of the present application provides another data packet sending method, and the embodiment is a specific implementation manner of the foregoing embodiments. Fig. 2 is a flowchart of another data packet sending method according to an embodiment of the present application, where the method includes the following steps:
step S201, obtaining an actual bandwidth utilization rate according to an actual receiving flow of the data packet in a preset time period.
This step can be referred to as step S101, and is not described herein.
Step S202, if the actual bandwidth utilization rate is less than or equal to the preset bandwidth utilization rate, determining that the historical time period is reduced to the amplitude of the first target time period according to the actual bandwidth utilization rate and the preset bandwidth utilization rate to obtain the first target time period, so as to improve the receiving flow of the data packet in the preset time period.
In one possible implementation manner, determining the amplitude of the historical time period reduced to the first target time period according to the actual bandwidth utilization rate and the preset bandwidth utilization rate may specifically be: and when the actual bandwidth utilization rate is less than or equal to the preset bandwidth utilization rate, reducing the historical time period by the fixed reduction amplitude to obtain a first target time period.
In another possible implementation manner, determining the amplitude of the historical time period reduced to the first target time period according to the actual bandwidth utilization and the preset bandwidth utilization specifically includes: and determining the amplitude of the historical time period reduced to the first target time period according to the difference or the ratio between the actual bandwidth utilization rate and the preset bandwidth utilization rate to obtain the first target time period. For example, it may be based on: the larger the difference between the actual bandwidth utilization rate and the preset bandwidth utilization rate is, the larger the reduction amplitude of the historical time period is, the closer the actual bandwidth utilization rate is to the preset bandwidth utilization rate, and the smaller the reduction amplitude is.
As an example, the value of the decrease in the historical time period may be proportional to the difference between the preset bandwidth utilization and the actual bandwidth utilization, e.g., the preset bandwidth utilization is 0.7 and the actual bandwidth utilization is
The value of the decrease in the historical time period may be
Wherein, C is a constant and can be set according to the actual situation. When the historical time period is T1Time, first target time period T2＝T1-X。
Taking the gateway as an example, it is assumed that the number of actually received packets in the preset time period T of 500ms is 5, where the data amount of each packet is 0.5Mb, 0.7Mb, 0.3Mb, and 02Mb and 0.4Mb, therefore, the data volume actually received in 500ms is the sum of the data volumes of the data packets, i.e. 2.1Mb, the average traffic actually received in the preset time period is 4.2Mb/s, the total bandwidth of the gateway is assumed to be 10Mb/s, the actual bandwidth utilization rate is the ratio of the actually received average data traffic to the total bandwidth of the gateway, i.e. α is 4.2/10 is 0.42, since the actual bandwidth utilization rate in the current preset time is less than the preset bandwidth utilization rate 0.7, the historical time period can be reduced, assuming that C is 20, the reduction amount of the historical time period is obtained, i.e. X is (0.7-0.42)/20 is 0.14(s), and assuming that the historical time period is T1500ms, the target time period T2＝T1-X＝360ms。
In other embodiments of the present application, the magnitude of the decrease of the historical time period may also be other values, which are determined according to practical situations and are not limited herein.
Step S203, if the actual bandwidth utilization is greater than the preset bandwidth utilization, using the historical time period as a first target time period for currently sending the data packet.
In the embodiment of the present application, if the actual bandwidth utilization rate is greater than the preset bandwidth utilization rate, it indicates that the actual bandwidth utilization rate is higher, and the system bandwidth is fully utilized, and the historical time period is used as the target time period for currently sending the data packet, and the data packet received in the last historical time period is sent.
Step S204, using the first target time period as the current time period for sending the data packet, and sending the data packet received in the last first target time period.
This step can be referred to as step S104, and is not described herein.
Step S205, taking the first target time period as the historical time period, returning to step S201 to determine the next time period of currently transmitting the data packet, and continuously executing the preset number of times to obtain each time period of currently transmitting the data packet.
The process of determining the time period of the next current data packet transmission is similar to the time period of the current data packet transmission, and is not described herein again.
Step S206, if the time period of the current data packet transmission corresponding to each time is the first target time period, then the data packet received in the last second target time period is transmitted with the second target time period as the time period of the current data packet transmission. Wherein the duration of the second target time period is greater than the duration of the first target time period.
In this embodiment of the present application, if the time period for currently sending the data packet corresponding to each of the preset times of continuous execution all uses the first target time period as the time period for the current data packet, which indicates that the actual bandwidth utilization is always higher than the preset bandwidth utilization, the second target time period may be used as the time period for currently sending the data packet, and the data packet received in the last second target time period is sent. The duration of the second target time period is greater than the duration of the first target time period, that is, the first target time period is added to the second target time period, and the increase amplitude may be a preset fixed value or may be determined according to the durations of one or more historical time periods.
Because the time period of the data packet is for suppressing the network jitter, the realization of the network jitter effect is affected by a too small sending period, and the suppression of the network jitter can be better realized while the bandwidth utilization rate is ensured by adding the first target time period to the second target time period.
The embodiment of the application can not only improve the bandwidth utilization rate when the actual bandwidth utilization rate is lower, but also can realize better network jitter inhibition and balance between the actual bandwidth utilization rate and the bandwidth utilization rate when the bandwidth utilization rate is higher by increasing the time period and ensuring the bandwidth utilization rate.
