Detailed Description
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 that can be derived by one of ordinary skill in the art from the description herein are intended to be within the scope of the present disclosure.
In a communication networking, the FEC technology can recover the original data packet that has been lost, so as to solve the problem of packet loss during data transmission.
As shown in fig. 1, the host in fig. 1 sends an original data packet to the router a through the local area network, and the router a performs FEC encoding on the original data packet according to a preset packet loss resistance rate to generate a redundant packet. And the router A sends the redundant message and the original data message to the router B through the wide area network. The router B performs FEC decoding on the received original data message and the redundant message and recovers the lost original data message. And the router B forwards the recovered original data message to a server for analysis and processing through the local area network, and discards the redundant message. Router a may also be referred to as a sending end, and router B may also be referred to as a receiving end.
The preset packet loss resistance rate is configured according to the actual packet loss rate of the network. The smaller the preset packet loss resistance rate is, the smaller the number of generated redundant messages is, and the smaller the occupied bandwidth is; the larger the preset packet loss resistance rate is, the more the number of generated redundant messages is, and the larger the occupied bandwidth is.
If the number of the generated redundant messages is less than the number of lost packets of the original data message, the complete original data message cannot be restored. Therefore, the preset packet loss resistance rate needs to be greater than the actual maximum packet loss rate of the network, so as to provide a powerful guarantee for data transmission. However, the actual packet loss rate of the network does not reach the maximum packet loss rate, so that the preset anti-packet loss rate is greater than the actual packet loss rate of the network, in this case, the redundant message is redundant, and the occupied bandwidth is large, thereby causing a slow data transmission speed.
In order to solve the above problem, an embodiment of the present application provides an anti-packet loss rate updating method. In the method, a sending end sends an original data message to a receiving end, and simultaneously, address information of an outgoing interface used for transmitting the original data message is also sent to the receiving end, under the condition, the receiving end can determine packet loss rates corresponding to quintuple information and address information, namely target packet loss rates, according to quintuple information and the address information of the outgoing interface included in the original data message, and the target packet loss rates can more accurately reflect link states of the original data message. And the sending end updates the packet loss resistance rate of the link for transmitting the original data message according to the target packet loss rate, namely the packet loss resistance rate corresponding to the quintuple information and the address information of the outgoing interface included in the original data message, so that the updated packet loss resistance rate is more suitable for the current network condition, the redundant situation of the redundant message is reduced, the situation of low data transmission speed caused by the redundant situation of the redundant message is reduced, and the data transmission speed is improved.
The following describes in detail the packet loss immunity updating method provided in the embodiment of the present application by using a specific embodiment.
As shown in fig. 2, fig. 2 is a first flowchart of a packet loss probability updating method provided in this embodiment of the application, where the packet loss probability updating method is applied to a transmitting end, and includes the following steps.
Step S201, an original data packet and an egress interface for transmitting the original data packet are obtained, where the original data packet includes quintuple information.
In this embodiment of the application, the original data packet may be a packet sent by the host to the sending end through the local area network, or a packet directly input by the user to the sending end. The quintuple information may be carried in a header of the original data packet.
After the sending end obtains the original data message, an outgoing interface used for transmitting the original data message can be determined by inquiring a forwarding table.
Step S202, sending the original data message and the address information of the output interface to the receiving end through the output interface, so that the receiving end determines the target packet loss rate corresponding to the address information and the quintuple information.
In the embodiment of the application, after acquiring an original data message and a corresponding output interface, a sending end acquires address information of the output interface; and sending the original data message and the address information of the output interface to a receiving end through the output interface. Different links correspond to different outgoing interface address information and quintuple information. The receiving end can obtain quintuple information from the original data message, and can determine the link for transmitting the original data message by combining the address information of the output interface, and further determine the packet loss rate of the link for transmitting the original data message according to the received original data message, namely the address information of the output interface and the target packet loss rate corresponding to the quintuple information.
Step S203, receiving a response message sent by the receiving end, where the response message includes the target packet loss rate.
The receiving end carries the target packet loss rate in the response message and feeds the response message back to the sending end. The sending end receives a response message containing the target packet loss rate.
In this embodiment of the application, in order to facilitate the sending end to accurately determine the link corresponding to the target packet loss rate, the load of the response packet may further include quintuple information and address information.
In order to reduce the pressure of the bandwidth, the response message may also include quintuple information, but not address information of the outgoing interface. In this case, after receiving the response message, the sending end extracts the address information of the outgoing interface from the quintuple information of the header of the response message. Here, the address information of the outgoing interface is the address information of the destination outgoing interface of the response message.
And step S204, updating the packet loss resistance rate corresponding to the address information and the quintuple information according to the target packet loss rate.
The sending end receives a response message sent by the receiving end through an outgoing interface, obtains a target packet loss rate corresponding to the quintuple information and the address information based on the response message, namely the target packet loss rate of a link for transmitting the original data message, and updates the packet loss resistance rate according to the target packet loss rate, wherein the packet loss resistance rate is greater than the target packet loss rate.
In an alternative embodiment, step S204 may specifically be: and performing addition operation on the target packet loss rate and a first preset parameter to obtain the packet loss resistance rate corresponding to the address information and the quintuple information, wherein the first preset parameter is greater than 0. The first preset parameter may be set according to actual requirements, for example, the first preset parameter is 0.05, 0.1, or 0.2.
In another alternative embodiment, step S204 may specifically be: and multiplying the target packet loss rate by a second preset parameter to obtain the packet loss resistance rate corresponding to the address information and the quintuple information, wherein the second preset parameter is greater than 1. The second preset parameter may be set according to actual requirements, for example, the second preset parameter is 1.1, 1.5 or 2.
In this embodiment of the application, the sending end may also determine the packet loss resistance rate in other manners, as long as it is ensured that the packet loss resistance rate is greater than the target packet loss rate, which is not limited herein.
In order to reduce the influence of redundant messages on the bandwidth, the smaller the first preset parameter and the second preset parameter, the better.
In the technical solution provided in the embodiment of the present application, while a sending end sends an original data packet to a receiving end, address information of an outgoing interface used for transmitting the original data packet is also sent to the receiving end, and in this case, the receiving end can determine a packet loss rate, i.e., a target packet loss rate, corresponding to quintuple information and address information according to quintuple information and address information of the outgoing interface included in the original data packet, and the target packet loss rate can more accurately reflect a link state of transmitting the original data packet. And the sending end updates the packet loss resistance rate of the link for transmitting the original data message according to the target packet loss rate, namely the packet loss resistance rate corresponding to the quintuple information and the address information of the outgoing interface included in the original data message, so that the updated packet loss resistance rate is more suitable for the current network condition, the redundant situation of the redundant message is reduced, the situation of low data transmission speed caused by the redundant situation of the redundant message is reduced, and the data transmission speed is improved.
In the embodiment of the application, the sending end can construct a detection message, carry the target address information in the detection message and send the detection message to the receiving end.
The sending end can also carry the target address information in the redundant message and send the redundant message to the receiving end. Therefore, the use of extra protocol messages can be avoided, the occupation of the broadband is reduced, and the data transmission speed is further improved. Specifically, as shown in fig. 3, the method for updating the packet loss resistance rate is applied to the transmitting end, and includes the following steps:
step S301, obtaining an original data message and an output interface for transmitting the original data message. Step S302 is the same as step S201.
Step S302, obtaining the packet loss resistance rate corresponding to the address information and the quintuple information.
In this embodiment, the sending end may store in advance a correspondence between the quintuple information, the address information of the outgoing interface, and the packet loss resistance rate. After acquiring an original data message and an output interface for transmitting the original data message, a sending end searches a target corresponding relation between address information of the output interface and quintuple information from a prestored corresponding relation. If the target corresponding relationship is found, the sending end takes the packet loss resistance rate in the target corresponding relationship as the packet loss resistance rate corresponding to the address information and the quintuple information.
If the target corresponding relationship is not found, the sending end may use the preset packet loss resistance rate as the packet loss resistance rate, may also directly forward the original data packet, and may not perform any processing, and is not limited to this.
Step S303, the data content of the original data message is FEC encoded by using the packet loss resistance rate, and a redundant message is obtained.
After the sending end obtains the packet loss resistance rate corresponding to the address information and the quintuple information, the sending end performs FEC encoding on the data content of the original data message by using the packet loss resistance rate to obtain a redundant message. The quantity of the redundant messages is determined by the packet loss resistance rate, and the smaller the packet loss resistance rate is, the smaller the quantity of the generated redundant messages is; the larger the packet loss resistance is, the more the number of generated redundant messages is.
Step S304, sending the original data message and the redundant message to the receiving end through the output interface, wherein the redundant message comprises address information.
The sending end sends the original data message and the redundant message to the receiving end through the output interface, and the redundant message comprises address information. And the receiving end extracts the address information of an output interface used for transmitting the original data message from the redundant message, extracts quintuple information from the original data message, and determines the target packet loss rate corresponding to the address information and the quintuple information according to the received original data message.
In the embodiment of the application, the address information is carried in the load of the redundant message. Under the condition, the sending end does not need to construct a protocol message, and an additional protocol message does not need to be transmitted between the sending end and the receiving end, so that the occupation of the update anti-packet loss rate on the broadband is reduced, and the data transmission speed is further improved.
Step S305, receiving a response message sent by the receiving end, wherein the response message comprises the target packet loss rate. Step S305 is the same as step S203.
Step S306, according to the target packet loss rate, updating the packet loss resistance rate corresponding to the address information and the quintuple information. Step S306 is the same as step S204.
According to the technical scheme provided by the embodiment of the application, the original data message and the redundant message are sent to the receiving end, the redundant message comprises address information, the use of an extra protocol message can be avoided, the occupation of a broadband is reduced, and the data transmission speed is further improved.
In an embodiment of the present application, an embodiment of the present application further provides an update method of an anti-packet loss rate, as shown in fig. 4, in the method, a response packet fed back to a sending end by a receiving end may further include a response type. In this case, the method for updating the packet loss resistance rate may include the following steps:
step S401, an original data message and an output interface for transmitting the original data message are obtained, wherein the original data message comprises quintuple information. Step S401 is the same as step S201.
Step S402, sending the original data message and the address information of the output interface to the receiving end through the output interface, so that the receiving end determines the target packet loss rate corresponding to the address information and the quintuple information. Step S402 is the same as step S202.
Step S403, receiving a response packet sent by the receiving end, where the response packet includes the target packet loss rate. Step S403 is the same as step S203.
Step S404, determining whether the response type included in the response message is an adaptive FEC type. If yes, go to step S405; if not, the packet loss rejection rate updating process is ended, i.e., the step S405 is refused to be executed.
In this embodiment of the application, if the response type is the adaptive FEC type, it indicates that the response packet sent by the receiving end may be used to update the packet loss resistance rate in the sending end, and step S405 is executed. If the response type is not the adaptive FEC type, it indicates that the response packet sent by the receiving end may not be used to update the packet loss resistance rate in the sending end, and step S405 is rejected.
Step S405, updating the packet loss resistance rate corresponding to the address information and the quintuple information according to the target packet loss rate. Step S405 is the same as step S204.
According to the technical scheme provided by the embodiment of the application, the response type is carried in the response message, and the update packet loss resistance rate of the sending end can be flexibly controlled based on the response type.
In an embodiment of the present application, an embodiment of the present application further provides an anti-packet loss rate updating method, as shown in fig. 5, in the method, a response packet fed back to a sending end by a receiving end may further include a time when the receiving end obtains a target packet loss rate, that is, a target time. In this case, the method for updating the packet loss resistance rate may include the following steps:
step S501, an original data packet and an egress interface for transmitting the original data packet are obtained, where the original data packet includes quintuple information. Step S501 is the same as step S201.
Step S502, sending the original data message and the address information of the output interface to the receiving end through the output interface, so that the receiving end determines the target packet loss rate corresponding to the address information and the quintuple information. Step S502 is the same as step S202.
Step S503, receiving a response message sent by the receiving end, where the response message includes the target packet loss rate. Step S503 is the same as step S203.
Step S504, determine whether the time difference between the current time and the target time is smaller than a first preset time threshold. If yes, go to step S505; if not, the packet loss rejection rate updating process is ended, i.e., step S505 is rejected.
In the embodiment of the application, a time threshold, that is, a first preset time threshold, is preset at a sending end. The first preset time threshold may be set according to actual requirements. For example, the first preset time threshold may be 50 milliseconds, 100 milliseconds, 200 milliseconds, or the like.
And after receiving the response message, the sending end acquires the target time from the response message and calculates the time difference between the current time and the target time. If the time difference is smaller than a first preset time threshold, the sending end can determine that a target packet loss rate carried by the response message is valid data, the target packet loss rate can adapt to the current network condition, and step S505 is executed to update the anti-packet loss rate; if the time difference is greater than or equal to the first preset time threshold, the sending end may determine that the target packet loss rate carried by the response packet is invalid data, and the target packet loss rate cannot adapt to the current network condition, and refuse to execute step S505.
And step S505, updating the packet loss resistance rate corresponding to the address information and the quintuple information according to the target packet loss rate. Step S505 is the same as step S204.
According to the technical scheme provided by the embodiment of the application, the response message carries the target time, and whether the target packet loss rate in the response message is suitable for the current network or not can be determined according to the time difference between the target time and the current time, so that the accuracy of the updated packet loss resistance rate of the sending end is improved, and the updated packet loss resistance rate is more suitable for the current network.
Corresponding to the above method for updating the packet loss resistance applied to the transmitting end, an embodiment of the present application further provides a method for updating the packet loss resistance, as shown in fig. 6, where fig. 6 is a fifth flowchart of the method for updating the packet loss resistance provided by the embodiment of the present application, and the method for updating the packet loss resistance is applied to the receiving end, and includes the following steps.
Step S601, receiving an original data packet and address information of an egress interface sent by a sending end through the egress interface, where the original data packet includes quintuple information.
In this embodiment of the application, the sending end may send the original data packet and the address information of the outgoing interface to the receiving end through the outgoing interface, and the specific process may refer to the related description of the step S201 to the step S203 in fig. 2, which is not described herein again.
In an embodiment of the present application, a sending end sends an original data packet and a redundant packet to a receiving end through an egress interface, where the redundant packet is obtained by performing FEC coding on data content of the original data packet by using packet loss resistance rates corresponding to address information and quintuple information, and the redundant packet includes address information. Based on the mode, the address information is transmitted, the occupation of the updated packet loss resisting rate on the broadband is reduced, and the data transmission speed is further improved.
Step S602, a target packet loss rate corresponding to the address information and the quintuple information is obtained.
Different quintuple information and interface address information correspond to different links. The receiving end can determine the link for transmitting the original data message according to the acquired address information and the quintuple information. And the receiving end determines the packet loss rate of the link, namely the target packet loss rate corresponding to the address information and the quintuple information, according to the received original data message and the lost original data message.
In the embodiment of the present application, a precondition of the target packet loss rate determined by the receiving end is that the received original data packet and/or the received redundant packet satisfy a decoding condition. The decoding conditions may specifically be: the method comprises the steps of receiving a specified number of messages (including original data messages and redundant messages), or not receiving the specified number of messages but receiving the messages for more than a specified time. The specified quantity is the total quantity of the original data messages sent by the sending end.
In the embodiment of the present application, packet loss does not necessarily exist in the network, that is, the original data packet is not necessarily lost. If the receiving end receives the original data messages with the specified number, namely no packet loss exists in the network, the target packet loss rate is not calculated, the received original data messages are directly forwarded to the server, and the redundant messages are cleared.
If packet loss exists in the network, but the quantity of the redundant messages and the original data messages received by the receiving end reaches the specified quantity, calculating the target packet loss rate, carrying out FEC decoding on the original data messages according to the redundant messages, recovering the complete original data messages, forwarding the recovered complete original data messages to a server, and emptying the redundant messages.
If packet loss exists in the network and the quantity of the redundant messages and the original data messages received by the receiving end does not reach the specified quantity, calculating the target packet loss rate, directly sending the received original data messages to the server, and clearing the redundant messages.
For example, the transmitting end transmits 10 original data messages and 2 redundant messages. And if the receiving end receives 10 original data messages, directly forwarding the received original data messages to the server, and clearing the redundant messages.
If the number of the original data messages received by the receiving end is less than 10, and the total number of the received original data messages and the total number of the received redundant messages reach 10, performing FEC decoding on the original data messages according to the redundant messages, recovering 10 original data messages, calculating a target packet loss rate, directly forwarding the recovered original data messages to a server, and emptying the redundant messages.
If the total number of the original data messages and the redundant messages received by the receiving end is less than 10, calculating the target packet loss rate, directly forwarding the original data messages to the server, and emptying the redundant messages.
Step S603, sending a response message to the sending end, where the response message includes the target packet loss rate, so that the sending end updates the packet loss resistance rate corresponding to the address information and the quintuple information according to the target packet loss rate.
In this embodiment, the response packet sent by the receiving end to the sending end may further include: quintuple information, target time for obtaining the target packet loss rate, and address information of a target output interface of a response message, that is, address information of an output interface used by the sending end for transmitting the original data message, so that the sending end can accurately update the packet loss resistance rate of the corresponding link.
In the technical solution provided in the embodiment of the present application, while a sending end sends an original data packet to a receiving end, address information of an outgoing interface used for transmitting the original data packet is also sent to the receiving end, and in this case, the receiving end can determine a packet loss rate, i.e., a target packet loss rate, corresponding to quintuple information and address information according to quintuple information and address information of the outgoing interface included in the original data packet, and the target packet loss rate can more accurately reflect a link state of transmitting the original data packet. And the sending end updates the packet loss resistance rate of the link for transmitting the original data message according to the target packet loss rate, namely the packet loss resistance rate corresponding to the quintuple information and the address information of the outgoing interface included in the original data message, so that the updated packet loss resistance rate is more suitable for the current network condition, the redundant situation of the redundant message is reduced, the situation of low data transmission speed caused by the redundant situation of the redundant message is reduced, and the data transmission speed is improved.
In an embodiment of the present application, an embodiment of the present application further provides an anti-packet loss rate updating method, as shown in fig. 7. The method is applied to a receiving end and comprises the following steps.
In an embodiment of the present application, an embodiment of the present application further provides an anti-packet loss rate updating method, as shown in fig. 7. The method is applied to a receiving end and comprises the following steps.
Step S701, receiving an original data message and address information of an outgoing interface sent by a sending end through the outgoing interface, wherein the original data message comprises quintuple information. Step S701 is the same as step S601.
Step S702, according to the received original data message and the address information, determining the original packet loss rate corresponding to the address information and the quintuple information.
In the embodiment of the application, after the original data message and the address information are received by the receiving end, quintuple information is extracted from the original data message, and then the packet loss rate corresponding to the address information and the quintuple information, namely the original packet loss rate, is determined.
In an embodiment of the present application, to facilitate subsequent determination of the target packet loss rate, the receiving end records a corresponding relationship between the address information, the quintuple information, the original packet loss rate, and the first statistic. And the first statistical time is the time of obtaining the original packet loss rate through statistics.
For example, the correspondence between the link, the original packet loss rate, and the first statistical time recorded by the receiving end is shown in table 1.
TABLE 1
In table 1, quintuple information 1 and interface address information 1 correspond to link 1, and quintuple information 1 and interface address information 2 correspond to link 2. Table 1 shows the original packet loss ratios of the links corresponding to different quintuple information and interface address information at different first statistical times, for example, when the packet loss ratio of the link 1 corresponding to the quintuple information 1 and the interface address information 1 is 9:00, the original packet loss ratio is 0.1.
Step S703 is to obtain a preset number of original packet loss rates from the original packet loss rates determined within the second preset time threshold.
In this embodiment of the application, the second preset time threshold may be set according to an actual requirement, for example, the second preset time threshold may be 30 minutes, 1 hour, or 2 hours. The preset number can be set according to actual requirements, for example, the preset number can be 10, 20 or 30.
The receiving end may randomly obtain a preset number of original packet loss rates from the original packet loss rates determined within the second preset time threshold periodically.
Step S704, calculating an average value of a preset number of original packet loss rates to obtain a target packet loss rate corresponding to the address information and the quintuple information.
And according to the address information and the quintuple information, the receiving end calculates an average value of the obtained preset number of original packet loss rates, wherein the calculated average value is a target packet loss rate corresponding to the address information and the quintuple information.
For example, two links shown in table 1 will be described as an example. The preset number is 10, the second preset time threshold is 1 hour, and the current time is 10: 00. The receiving end obtains 10 original packet loss rates from the original packet loss rate of the link 1 recorded in the range from 9:00 to 10:00, and calculates the average value of the 10 original packet loss rates to obtain the packet loss rate of the link 1 as the target packet loss rate 1 of the link 1; obtaining 10 original packet loss rates from the original packet loss rates of the link 2 recorded in the range from 9:00 to 10:00, and calculating an average value of the 10 original packet loss rates to obtain a packet loss rate of the link 2 as a target packet loss rate 2 of the link 2.
Step S702-step S704 are refinements of step S602.
Step S705, sending a response message to the sending end, where the response message includes the target packet loss rate, so that the sending end updates the packet loss resistance rate corresponding to the address information and the quintuple information according to the target packet loss rate. Step S705 is the same as step S603.
In the technical scheme provided by the embodiment of the application, the average value of the original packet loss rates of the preset number within the second preset time threshold is calculated and used as the target packet loss rate, so that the influence of the measured original packet loss rate on the sudden size or the sudden size caused by uncertain factors is reduced, the obtained target packet loss rate is representative, the accuracy and the reliability of the target packet loss rate are improved, and the calculation result can more accurately reflect the current link state.
In an embodiment of the present application, in order to save the storage space of the receiving end, after the target packet loss rate is obtained in step S704, the original packet loss rate of the link within the second preset time threshold is cleared.
The description will be made by taking an example in step S704. After obtaining the target packet loss rate 1 of the link 1 based on the original packet loss rate of the link 1 recorded in 9:00 to 10:00, the receiving end clears all the original packet loss rates of the link 1 recorded in 9:00 to 10: 00; after the target packet loss rate 2 of the link 2 is obtained based on the original packet loss rate of the link 2 recorded in 9:00 to 10:00, emptying all the original packet loss rates of the link 2 recorded in 9:00 to 10: 00.
