Description

Network optimization method, device and system

Technical Field

The present invention relates to the technical field of network optimization, and in particular, to a method, an apparatus, and a system for network optimization.

Background

In an application scene of real-time audio and video communication, a client needs to be connected with a server to realize transmission of audio and video data. Due to the fact that states of regions, network operators and client equipment are different, different servers need to be allocated to different clients, data transmission strategies can be adjusted in real time when data output is in a problem, if the servers are in a fault, other servers can be allocated to the clients quickly, and usability and instantaneity of audio and video data transmission are guaranteed.

The currently common scheme is to allocate the server with the optimal client to the optimal client in a scheduling manner, and switch to a new server when a failure occurs, wherein the scheduling manner mainly includes the following two manners: a DNS (Domain Name System) based scheduling method, and an http DNS (http DNS) based scheduling method. For a dispatching mode based on DNS, a local DNS server uses cache, data updating is delayed, the whole network takes 10-20 minutes to take effect, the requirement of real-time dispatching cannot be met, and the problems of DNS hijacking and the like exist. For the dispatching mode based on the http dns, only the static server IP list is maintained, the dispatching can be performed only according to the region of the client, the operator, and the like, and different server IP lists cannot be taken according to the state of each client, so that the dispatching granularity is not fine enough, and the network optimization cannot be completed in real time in a targeted manner.

The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

The network optimization method provided by the embodiment of the invention realizes network optimization between the client and the server based on the strategy information. In this embodiment, the method for network optimization is executed by a client, as shown in fig. 1, the method includes steps 101-103:

step 101: determining current policy information, the current policy information including current data parameters, current network parameters, and a server list.

In the embodiment of the invention, when a client needs to send data to a server, firstly, the policy information needed to be used by the client, namely the current policy information, is determined; the current policy information specifically includes current data parameters, current network parameters, and a server list. The current data parameter is a currently used parameter related to data to be transmitted, and the current network parameter is a currently used parameter related to a network. For example, if the client needs to send audio/video data, the current data parameter may include one or more of a maximum resolution, a maximum frame rate, and a maximum code stream; the change of the current data parameters can affect the size of the audio and video stream, so that the size of network transmission data is changed. The current network parameters may include: one or more of UDP (User Datagram Protocol) message size, UDP packet sending rate and packet loss compensation strategy; the appropriate current network parameters can be specifically set according to the network environment, so that the data transmission performance is improved.

In addition, the server list includes addresses (such as IP addresses) of a plurality of servers, and the server list may be stored locally in advance or issued by the scheduling server. Optionally, the step of "determining current policy information" includes steps a 1-A3:

step A1: and sending a connection request to a scheduling server, wherein the connection request comprises a client identification of the client and a sending time for sending the connection request.

In this embodiment, when the client needs to upload data, the client calls an interface of the scheduling server, so as to send a connection request including a client identifier and sending time to the scheduling server, and notify the scheduling server that the local client needs to upload data, so that the scheduling server can feed back a server list available to the client. The client identifier may specifically be an IP address of the client.

Step A2: and acquiring basic strategy information fed back by the scheduling server, wherein the basic strategy information is strategy information determined by the scheduling server according to the client identification and generated according to the time difference between the sending time and the receiving time of the received connection request, and the basic strategy information comprises a data parameter range, a network parameter range and a server list.

In this embodiment, after acquiring the client identifier and the sending time, the scheduling server may determine the belonging information of the client according to the client identifier, where the belonging information refers to related information to which the client belongs, such as a region to which the client belongs, an operator to which the client belongs, and the like. Meanwhile, the scheduling server may determine a receiving time when the connection request is received, calculate a network speed between the client and the server based on a time difference between the receiving time (i.e., a time when the scheduling server receives the connection request) and a sending time (i.e., a time when the client sends the connection request), and determine a server list, a data parameter range and a network parameter range, which are applicable to the client, based on the belonging information and the network speed, that is, may generate basic policy information, and send the basic policy information to the client. The policy information (including the basic policy information and the current policy information) in this embodiment may be in a file format, so as to facilitate transmission of the policy information between the client and the server.

Step A3: and setting the current data parameters according to the data parameter range, setting the current network parameters according to the network parameter range, and generating current strategy information according to the current data parameters, the current network parameters and the server list.

In this embodiment, after receiving the basic policy information, the client sets the data parameters and the network parameters based on the local actual situation or according to a normal manner, that is, sets the current data parameters and the current network parameters. Specifically, a current data parameter is set according to a data parameter range, and the current data parameter needs to be located within the data parameter range; correspondingly, the current network parameter is set according to the network parameter range, and the current network parameter is located in the network parameter range. Further, the current policy information may be determined based on the current data parameters, current network parameters, and the server list.

Step 102: and selecting one server from the server list as a target server, and sending target data matched with the current data parameters to the target server based on the current network parameters.

In the embodiment of the invention, after the client determines the server list, one server can be selected from the server list as a server needing to upload data, namely a target server. Meanwhile, the data needing to be uploaded at present, namely the target data, is determined, and the target data matched with the current data parameters are sent to the target server based on the current network parameters. For example, the video data with resolution ratio according to the current data parameter is used as the target data, and the video data is sent according to the corresponding message size and packet sending speed. The first server in the server list may be used as a target server, and after the test may be performed to connect the target server, the target data may be sent to the target server.

Optionally, if the connection between the client and the target server fails to be established, or the client receives a server replacement request sent by the target server, the client may select another server from the server list as the target server. In this embodiment, if the client and the target server cannot establish a connection due to an abnormal communication therebetween, the client needs to replace another server as the target server. Or, although the communication connection is established between the client and the target server, the communication quality between the client and the target server is poor, and the target server can generate a server replacement request at the moment, so that the client can replace other servers.

Further, if all servers in the server list cannot be used as target servers, the client may send a policy information update request to the scheduling server, and obtain new basic policy information fed back by the scheduling server, where the basic policy information includes a data parameter range, a network parameter range, and a server list. The policy information update request is essentially the same as the connection request, and is used to instruct the scheduling server to generate policy information, the process of which is basically the same as that of the above step a1-a2, and is not described herein again.

Step 103: acquiring an adjustment parameter instruction issued by a target server, adjusting current data parameters and/or current network parameters according to the adjustment parameter instruction, and sending target data matched with the adjusted current data parameters to the target server based on the adjusted current network parameters; and the parameter adjusting instruction is an instruction generated by the target server according to the data transmission state.

In the embodiment of the invention, when the communication connection is established between the client and the target server and the target data is sent, the target server can also generate a corresponding parameter adjusting instruction based on the current data transmission state, so that the data transmission state between the client and the target server is adjusted in real time, and the network optimization is carried out in real time. In this embodiment, the client may adjust the corresponding current data parameter and/or current network parameter based on the parameter adjustment instruction, and continue to send the target data to the target server. Specifically, the client can adjust the current data parameters according to the adjustment parameter instruction, and send the target data matched with the adjusted current data parameters to the target server based on the current network parameters; or the client can adjust the current network parameters according to the parameter adjusting instruction and send target data matched with the current data parameters to the target server based on the adjusted current network parameters; or the client can also adjust the current data parameters and the current network parameters according to the parameter adjusting instruction, and send the target data matched with the adjusted current data parameters to the target server based on the adjusted current network parameters. In this embodiment, "target data" is data that the client needs to upload, and since the client continuously sends the target data to the target server, the content included in the "target data" in step 102 may be different from the content included in the "target data" in step 103, but both of the contents are data that the client needs to upload.

According to the network optimization method provided by the embodiment of the invention, the client can carry out network request based on the strategy information, select a proper target server through the server list and send data based on the current data parameter and the current network parameter, so that the current communication process can adapt to the network state; meanwhile, the update strategy information can be adjusted in real time based on the adjustment parameter instruction fed back by the target server, so that the network is optimized in real time, the optimization granularity is finer, and the adjustment mode is diversified.

On the basis of the foregoing embodiment, the parameter adjustment instruction issued by the target server may be a detailed instruction, and the client may execute the instruction when receiving the parameter adjustment instruction, where, in this case, the step 103 "adjusting the current data parameter and/or the current network parameter according to the parameter adjustment instruction" includes:

step B1: and if the parameter adjusting instruction is a network parameter improving instruction, improving the current network parameter.

Step B2: and if the parameter adjusting instruction is a data parameter increasing instruction, increasing the current data parameter.

Step B3: and if the parameter adjusting instruction is a network parameter reducing instruction, reducing the current network parameter.

Step B4: and if the parameter adjusting instruction is a data parameter reducing instruction, reducing the current data parameter.

In the embodiment of the invention, the target server can determine how to adjust the parameters according to the current data transmission state, and further can directly instruct the client to adjust the network parameters or the data parameters. Specifically, if the current data transmission state is good, the target server may generate a network parameter promotion instruction, so that the client may promote the current network parameter, that is, the client may send the target data to the target server with a higher current network parameter (e.g., a higher packet sending rate); if the parameter adjusting instruction is a data parameter increasing instruction, the client may increase the current data parameter, so that the client may send target data meeting higher data parameters (e.g., video data with higher resolution). On the contrary, if the current data transmission state is poor, the target server needs to generate a network parameter reduction instruction or a data parameter reduction instruction to reduce the network transmission requirement between the client and the target server.

Optionally, in order to preferentially ensure the fluency of data transmission and avoid increasing delay, when the current data transmission state is good, the target server preferentially generates a network parameter promotion instruction, and when the current network parameter of the client is greater than a first preset value (for example, reaches an upper limit), the target server generates a data parameter promotion instruction again; or the requirement for generating the data parameter promoting instruction is higher than the requirement for generating the network parameter promoting instruction. For example, the target data is video data, and if the packet loss rate of the client is lower than 3% within 10 seconds, the target server generates a network parameter increasing instruction, so that the client is notified to increase the network parameters in the policy information by 5%; if the client can keep a lower packet loss rate in the next 10 seconds, the network parameters of the client are continuously improved; when the network state is very good (for example, the available bandwidth reaches 5Mbps), a data parameter promoting instruction can be generated to notify the client of promoting the data parameters in the strategy information, so that the client can upload high-resolution and high-definition video data to the target server.

Correspondingly, if the current data transmission state is poor, the target server preferentially generates a data parameter reduction instruction, and when the current data parameter of the client is smaller than a second preset value (for example, the current data parameter reaches the lower limit), the target server generates a network parameter reduction instruction; alternatively, the requirement to generate the reduced data parameter instruction is lower than the requirement to generate the reduced network parameter instruction. For example, if the packet loss rate of the client is higher than 20% within 10 seconds continuously, the target server generates a data parameter reduction instruction to inform the client to reduce data parameters, reduce audio and video quality and reduce audio and video data transmission; and if the packet loss rate is still kept above 15% in the next 10 seconds, the target server generates a network parameter reduction instruction again and informs the client to reduce the network parameters in the strategy information. Further, if the data parameter and the network parameter both fall below the minimum threshold value, and the packet loss rate has not improved yet, the target server may notify the client to replace another server.

Or, the parameter adjusting instruction issued by the target server may be a basic instruction, and the client performs adaptive adjustment based on the local actual situation after receiving the parameter adjusting instruction, at this time, the step 103 "adjusting the current data parameter and/or the current network parameter according to the parameter adjusting instruction" includes:

step C1: if the parameter adjusting instruction is a parameter lifting instruction, lifting the current network parameters, and lifting the current data parameters when the current network parameters cannot be lifted.

Step C2: and if the parameter adjusting instruction is a parameter reducing instruction, reducing the current data parameter, and reducing the current network parameter when the current data parameter can not be reduced.

In the embodiment of the invention, when the current data transmission state is good, the target server can generate a parameter promotion instruction and inform the client of promoting the network parameters and/or the data parameters. Meanwhile, the client further determines whether to promote the network parameter or promote the data parameter based on the current parameters (such as the current network parameter, the current data parameter, and the like). Similarly, in order to preferentially ensure the fluency of data transmission and avoid increasing delay, the client preferentially promotes the current network parameters, and promotes the current data parameters under the condition of very good network state; similarly, the client reduces the current data parameter preferentially, and then reduces the current network parameter.

In the embodiment, the parameter adjusting instruction is generated in real time, so that the parameters can be adjusted up when the network state is good, and the transmission fluency and the data quality are improved; and when the network state is not good, the parameters are adjusted downwards to ensure the fluency of transmission. Meanwhile, the network parameters are preferentially improved, the data parameters are preferentially reduced, the smoothness of data transmission is preferentially guaranteed, and delay is prevented from being increased.

Based on the same inventive concept, an embodiment of the present invention further provides a method for network optimization performed by a server, which is shown in fig. 2 and includes:

step 201: and acquiring target data sent by the first client, and determining the data transmission state between the first client and the target data.

In the embodiment of the invention, when the first client needs to send data to the server, the first client and the server can establish communication connection, so that the first client can send target data to the server. Specifically, the first client may be provided with policy information including a current data parameter, a current network parameter, and a server list, where the server is one of the server lists, and the first client selects the server from the server list as a target server, and sends target data matched with the current data parameter to the server based on the current network parameter. The "first client" is substantially the same as the "client" in the foregoing embodiment, and the process of determining the policy information and sending the target data by the first client may be referred to the foregoing embodiment, which is not described herein again.

Meanwhile, when the first client sends the target data to the server, the server also determines the data transmission state between the first client and the server in real time, for example, determines the packet loss rate, the available bandwidth and the like, so that the data transmission state between the first client and the server can be adjusted in real time subsequently.

Step 202: and generating a corresponding adjustment parameter instruction according to the data transmission state, sending the adjustment parameter instruction to the first client, instructing the first client to adjust the current data parameter and/or the current network parameter according to the adjustment parameter instruction, and continuously sending target data matched with the adjusted current data parameter based on the adjusted current network parameter.

In the embodiment of the invention, the server can generate the parameter adjusting instruction in real time based on the data transmission state between the server and the first client, so that the first client can adjust the corresponding strategy information, namely the first client can adjust the current data parameter and/or the current network parameter, and further the first client can continuously send the target data matched with the adjusted current data parameter based on the adjusted current network parameter.

Optionally, the server may generate a detailed parameter adjustment instruction based on the current data transmission state, and the client may execute the parameter adjustment instruction when receiving the parameter adjustment instruction; in this embodiment, the data transmission state may include a packet loss rate and an available bandwidth, and the step 202 of generating the corresponding parameter adjustment instruction according to the data transmission state includes:

step D1: and when the packet loss rate meets the lifting condition and the available bandwidth is smaller than a first preset threshold value, generating a network parameter lifting instruction and indicating the first client to lift the current network parameter.

Step D2: and when the packet loss rate meets the lifting condition and the available bandwidth is greater than a second preset threshold, generating a data parameter lifting instruction and indicating the first client to lift the current data parameter.

In the embodiment of the present invention, when the current data transmission state is better, it indicates that the network state between the server and the first client is better, and at this time, the network parameter and/or the data parameter may be appropriately promoted. In this embodiment, a condition for improving the packet loss rate is preset, for example, the packet loss rate is less than 3%, and a first preset threshold and a second preset threshold of the available bandwidth are preset. Specifically, when the packet loss rate meets the promotion condition and the available bandwidth is smaller than the first preset threshold, it is indicated that the network state between the server and the first client is good (i.e., the packet loss rate is low), but the available bandwidth (throughput) is general, at this time, only the network parameters such as the packet size and the packet sending rate can be promoted, so as to ensure the fluency during data transmission. When the packet loss rate meets the lifting condition and the available bandwidth is greater than the second preset threshold, the current network state is good, the available bandwidth is good, and the data parameter can be lifted at the moment, so that the first client can send target data with higher current data parameters.

For example, the target data to be uploaded by the first client is video data, and if the packet loss rate of the first client is lower than 3% within 10 seconds continuously and the available bandwidth determined by the server is lower than 1Mbps, the server may generate a network parameter promotion instruction, so as to notify the first client to promote the network parameters in the policy information by 5%; if the first client can still keep a low packet loss rate (if the packet loss rate is lower than 3%) in the next 10 seconds, the network parameters of the first client can be continuously improved; if the packet loss rate of the first client is still low and the available bandwidth reaches 5Mbps, which indicates that the current network state is very good, the server may generate a data parameter promotion instruction to notify the first client of promoting the data parameters in the policy information, so that the first client may upload high-resolution and high-definition video data to the server.

Step D3: and when the packet loss rate meets the reduction condition, generating a data parameter reduction instruction and indicating the first client to reduce the current data parameter.

Step D4: and when the packet loss rate meets the reduction condition and a data parameter reduction instruction is generated, generating a network parameter reduction instruction and indicating the first client to reduce the current network parameters.

In the embodiment of the invention, when the current data transmission state is poor, the network state between the server and the first client is poor, and at the moment, the network parameter and/or the data parameter can be properly reduced. In this embodiment, a condition for reducing the packet loss rate is preset, for example, the packet loss rate is greater than 15%. Specifically, when the packet loss rate satisfies the reduction condition, it indicates that the network state between the server and the first client is poor (i.e., the packet loss rate is relatively high), and at this time, to ensure the smoothness of data transmission, the server generates a data parameter reduction instruction to reduce data parameters such as resolution and code stream of the target data transmitted by the first client. If the packet loss rate meets the reduction condition and the instruction for reducing the data parameter is generated, it indicates that the current network is poor, and the flow performance is still not guaranteed enough even if the data parameter is reduced (because the packet loss rate is still high), at this time, the server may generate the instruction for reducing the network parameter, so as to reduce the network parameters such as the size of the message, the packet sending rate, and the like. If both the data parameter and the network parameter fall below the minimum threshold and the packet loss rate has not improved, the server may notify the first client to replace another server, e.g., the server may generate a server replacement request.

Optionally, in order to preferentially ensure the fluency of data transmission and avoid increasing delay, if the current data transmission state is good, the server preferentially generates a network parameter promotion instruction, and when the current network parameter of the first client is greater than a first preset value (for example, reaches an upper limit), the server generates a data parameter promotion instruction again; or the requirement for generating the data parameter promoting instruction by the server is higher than the requirement for generating the network parameter promoting instruction. Correspondingly, if the current data transmission state is poor, the server preferentially generates a data parameter reduction instruction, and when the current data parameter of the first client is smaller than a second preset value (for example, the current data parameter reaches a lower limit), the server generates a network parameter reduction instruction; alternatively, the server may generate a lower data parameter reduction instruction than the network parameter reduction instruction. The specific process can refer to the related contents of steps B1-B4 in the above embodiments, which are not described herein again.

Or, the parameter adjusting instruction issued by the server may be a basic instruction, and the first client may perform adaptive adjustment based on the local actual condition after receiving the parameter adjusting instruction; specifically, the step 202 "generating a corresponding parameter adjusting instruction according to the data transmission state" includes:

step E1: and when the data transmission state meets the lifting condition, generating a lifting parameter instruction, and indicating the first client to lift the current data parameter and/or the current network parameter.

Step E2: and when the data transmission state meets the reduction condition, generating a parameter reduction instruction, and indicating the first client to reduce the current data parameter and/or the current network parameter.

In the embodiment of the present invention, the server may preset a promotion condition and a reduction condition, and generate a corresponding instruction (a parameter promotion instruction or a parameter reduction instruction) when the data transmission state satisfies the corresponding condition, so that the first client may promote or reduce the corresponding parameter. For example, the lifting condition may be that the packet loss rate is less than a certain value (e.g., 3%), and the lowering condition may be that the packet loss rate is greater than another value (e.g., 20%). After receiving the corresponding instruction, the first client may perform an adaptive adjustment based on the local actual situation to determine an adjusted network parameter and/or data parameter.

Step E3: and when the data transmission state does not meet the communication condition, generating a server replacement request, and instructing the first client to reselect other servers from the server list as target servers.

In this embodiment, if the data parameter and the network parameter are both reduced to be lower than the minimum threshold value and the packet loss rate is not improved yet, and the data transmission state at this time does not satisfy the communication condition, the server may notify the first client to replace another server, that is, the server may generate a server replacement request, so that the first client reselects another server from the server list as the target server.

According to the method for optimizing the network, provided by the embodiment of the invention, the server can generate a corresponding parameter adjusting instruction based on the current data transmission state, and adjust the network parameters and the data parameters used by the client during data transmission, so that the client can adjust the strategy of sending data in real time based on the adjusted network parameters and data parameters, the network is optimized in real time, the optimization granularity is finer, and the adjustment modes are diversified. The client sets strategy information containing network parameters and data parameters, and supports the server to adjust the parameters in real time.

On the basis of the above embodiment, the server may also serve as a scheduling server to generate initial policy information, i.e., basic policy information, for the client. Specifically, the method further comprises:

step F1: and acquiring a connection request sent by the second client, wherein the connection request comprises a client identifier of the second client and sending time for sending the connection request.

Step 310: and the client reselects other data servers from the server list as target servers and continues to send the target data.

Step 311: and when all the data servers in the server list cannot be used as target servers, the client sends a policy information updating request to the scheduling server.
