Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures. In addition, the embodiments and features of the embodiments in the present invention may be combined with each other without conflict.
Fig. 1 is a schematic flowchart of a media server distribution method according to an embodiment of the present invention, where the method may be performed by a media server distribution apparatus, where the apparatus may be implemented by software and/or hardware, and may be generally integrated in a computer device such as a server. For example, for an application program with an audio/video communication function (hereinafter referred to as a preset application program), a client is generally installed in a mobile terminal such as a mobile phone, and a corresponding server can allocate a media server to the client that needs to perform a call by executing the media server allocation method provided by the embodiment of the present invention, and the client establishes a network connection with the allocated media server, so as to implement network transmission of audio/video call data.
As shown in fig. 1, the method includes:
For example, when a first user initiates an audio/video call request to a second user through a client of a preset application installed on a mobile terminal used by the first user, it may be detected that an audio/video call event is triggered, where the client used by the first user is a calling party and the client used by the second user is a called party.
For example, for an internationalized call environment, network quality varies widely from country to country, and network quality needs to be evaluated from finer-grained users. The client attribute information may include, for example, a geographic location, a network type, a network service operator, and the like corresponding to the client. Wherein, the geographic location may include a country, a region, a city, or the like; the network types may include, for example, operator networks, wireless local area networks, and the like; the network service operator may be the name or identity of the operator providing the mobile network service to the current client, etc.
For example, the media servers may be deployed in a plurality of areas, at least one media server exists in each area, available area lists corresponding to different client attributes may be preset according to the distribution conditions of the media servers, and then, after it is detected that an audio/video call event is triggered, an area in the corresponding available area list may be quickly determined as an available area that needs to be further screened currently according to client attribute information.
In the embodiment of the invention, each media server in the preset media server set can be detected by different clients through the preset data packet sequence, so that network performance related data between the clients and the media servers, namely detection data, can be obtained in advance. The preset set of media servers may be all or part of the media servers deployed within a service scope (e.g., in an international call service, the service scope may include multiple countries or even the world) for a preset application. If the media servers are part of the media servers, the determination may be performed according to the regions, for example, one media server is selected from each region and added to the preset media server set.
For example, the preset data packet sequence may include a plurality of probe packets, and the number of the probe packets, the sending interval of the probe packets, the size of the probe packets, and the like may be set according to actual requirements.
Illustratively, the at least two network performance indicators may include, for example, an average response time, a packet reception success rate, a packet loss rate, a network delay jitter, and the like. Average Response Time (Average Response Time) is also called Round-Trip Time (RTT); the data packet receiving success rate can represent the ratio of the number of the successfully received detection packets to the total number of the sent detection packets, and can reflect the survival condition of the data packets of the round-trip path; the packet loss rate of the data packet may represent the ratio of the number of lost detection packets to the total number of sent detection packets, and may reflect the packet loss condition of the round-trip path; the network delay Jitter (Jitter) can be determined by the difference between the maximum RTT and the minimum RTT, and reflects the fluctuation condition of the network.
In the related art, when determining the allocation priority of the media server, the performance index to be considered is small, and usually only the response time is considered, so that it is difficult to perform allocation reasonably. In addition, in the related art, detection is generally performed after an audio/video call is initiated, and the detected data can only represent the current network condition in a short time, which further causes inaccuracy of a detection result and affects the distribution efficiency of the media server.
In the embodiment of the invention, the network performance detection data set is constructed in a mode of detecting and collecting the detection data in advance, and after the audio and video call event is detected to be triggered, the required detection data can be rapidly acquired from the network performance detection data set, so that the media server to be allocated is rapidly determined, the allocation efficiency is improved, the network connection is rapidly completed, and the audio and video call experience is improved.
For example, the first score may be used to reflect the overall network performance of the routing path of the network connection formed by the calling party to the currently available area to the called party, with the currently available area being employed. For each available region, a corresponding first score may be determined from the corresponding first detection data and second detection data. The first preset scoring rule may be designed according to a type of a network performance indicator included in the probe data. For a certain network performance index, a first index value may be determined according to a value in the corresponding first detection data and a value in the corresponding second detection data, and the determination manner may be, for example, addition, weighted sum, averaging, taking a maximum value, taking a minimum value or product, and the like. The first preset scoring rule may be, for example, the sum, weighted sum or weighted sum of squares, etc. of the first index values of the respective network performance indexes.
And step 104, determining a target area according to the first score, determining a target media server corresponding to the audio and video call event according to a media server existing in the target area, and distributing.
For example, the selectable region with the highest first score may be determined as the target region, or a plurality of candidate regions may be screened out on the basis of the first score, and the target region may be further determined on the basis of the plurality of candidate regions, which is not limited specifically. Optionally, after the target area is determined, any media server in the target area may be determined as a target media server to be allocated corresponding to the current audio/video call event, a media server closest to the calling party and/or the called party in the target area may also be determined as a target media server to be allocated, or a target media server may be selected from the target area according to other preset rules.
The media server distribution method provided by the embodiment of the invention detects that the audio and video call event is triggered, determining a plurality of available areas containing media servers according to client attribute information respectively corresponding to a calling party and a called party, acquiring first detection data between the calling party and each available area and second detection data between the called party and each available area from a first network performance detection data set collected in advance, wherein the detection data comprises data of at least two network performance indexes obtained by detecting by using a preset data packet sequence, a first score corresponding to each available area is determined by using a first preset scoring rule based on the first detection data and the second detection data, and determining a target area according to the first score, and determining and distributing a target media server corresponding to the audio and video call event according to the media servers existing in the target area. By adopting the technical scheme, when the media server is required to be allocated for the audio and video call event, each available area is scored according to the pre-collected detection data containing a plurality of network performance indexes, so that a reasonable target area can be rapidly and accurately determined, the media server in the target area is allocated to a call party, and the audio and video call performance is favorably improved.
For a home-based call environment, the forwarding of media servers across machine rooms can be considered in combination with the network quality among different machine rooms. In some embodiments, said determining a target region from said first score comprises: screening candidate regions from the plurality of available regions according to the first score; determining candidate region pairs, acquiring third detection data among the candidate region pairs from a second network performance detection data set collected in advance, and determining second scores corresponding to the candidate region pairs by using a second preset scoring rule based on the first detection data, the second detection data and the third detection data; the advantage of determining the target area according to the sequence of the first score and the second score of the candidate area is that a media server can be added on a routing path of network connection between a calling party and a called party, and for long-distance communication scenes such as international communication, a routing forwarding mode crossing a machine room can be provided, so that the overall network connection quality is ensured, and the communication experience is further improved.
For example, a preset number of available regions with the highest first score may be selected as candidate regions, for example, a preset number of available regions with a top rank may be selected as candidate regions after being sorted from high to low according to the first score. The preset number may be determined according to actual conditions such as calculation power of the server, for example, may be 5, that is, after the ranking, the available region 5 before the ranking is determined as the candidate region. After the candidate regions are determined, pairwise combination can be performed on the multiple candidate regions to obtain candidate region pairs; and selecting a candidate region pair which is closer to the calling party and a candidate region pair which is closer to the called party according to the distance between the candidate region and the calling party and the distance between the candidate region and the called party.
After adding a media server to the routing path of the network connection between the calling party and the called party, the network performance between the two media servers also needs to be considered, and therefore, probe data between media servers in different regions may be collected in advance, forming a second network performance probe data set, after determining the candidate region pair, third probing data between two candidate regions of the candidate region pair is directly obtained from the second network performance probing data set, a second score is calculated from the first detection data, the second detection data and the third detection data corresponding to the candidate region pair, the second score may be used to reflect that in case the current candidate region pair is employed, the whole network performance of the routing path of the network connection formed by the calling party to the first candidate area, then to the second candidate area and finally to the called party. Assuming that a calling party is a user A, a called party is a user B, a first candidate area is a, a second candidate area is B, the first detection data reflects the network performance between the users A and a, the third detection data represents the network performance between a and B, the second detection data reflects the network performance between B and the user B, and the corresponding score of the candidate area pair of a and B adopted on the routing path of the network connection can be determined according to the detection data.
The second preset scoring rule may be designed according to the type of the network performance index included in the probe data. For a certain network performance index, a second index value may be determined according to a value in the corresponding first detection data, a value in the second detection data, and a value in the third detection data, where the determination manner may be, for example, addition, weighted sum, averaging, taking a maximum value, taking a minimum value or product, and the like. The second preset scoring rule may be, for example, the sum, weighted sum or weighted sum of squares, etc. of the second index values of the network performance indicators.
In some embodiments, further comprising: under the condition that a target client side is determined to meet preset detection conditions, issuing a detection task to the target client side, and recording client side attribute information corresponding to the target client side, wherein the detection task comprises detection parameters used for determining a preset data packet sequence, and the client side attribute information comprises at least one of a geographic position, a network type and a network service operator; receiving detection data returned by the target client after executing the detection task, wherein the detection task is executed for each media server in a preset media server set; and summarizing the detection data returned by the target clients by taking the client attribute information and the area of the media server as summarizing dimensions to obtain a first network performance detection data set. The advantage of this is that the acquisition and aggregation of the probe data can be performed in advance to form an accurate first network performance probe data set. The first network performance probe data set may be understood as a pre-constructed routing decision table from the user terminal to the media server.
For example, meeting the preset detection condition may include that the target client is not in the audio/video call process, and the target client avoids executing the detection task to affect the call of the target client, and specifically, the detection task may be issued to the target client after detecting that the call of the target client is ended, where the detection task may include detection parameters such as the number of detection packets, the sending interval of the detection packets, and the size of the detection packets, and the preset data packet sequence is determined according to the detection parameters, the detection packets are sent to each media server in the preset media server set that needs to be detected according to the preset data packet sequence, and the feedback condition of each media server is recorded, so that the detection data is calculated and reported to the server. After receiving the detection data reported by the multiple target clients, the server may aggregate the detection data according to the time dimension of a preset time level (e.g., according to day, hour, or minute, different countries or regions may correspond to different preset time levels, for example, a key country may be set to a minute level to ensure timeliness of the detection data set), and then summarize the client attribute information and the region to which the media server belongs as a summarization dimension to obtain a first network performance detection data set. For example, the client attribute information includes countries, and may summarize the detection data from the clients whose geographic locations are different countries to each region; for another example, the client attribute information includes countries and operators, and may summarize probe data from clients with geographic locations of different countries and different operators to each area, and the like, for example, the geographic location is the united states, and probe data from china moving to area c and probe data from china communicating to area c are summarized separately. The more items contained in the client attribute information, the finer the summarizing granularity, and the more accurate the selection of the target media server can be performed under the condition that the plurality of items of client attribute information of the calling party and the called party can be obtained.
In some embodiments, the sending the probe task to the target client further includes: sending the detection task to a target media server in the preset media server set; receiving detection data returned by the target media server after executing the detection task, wherein the current target media server executes the detection task aiming at other media servers except the current target media server in the preset media server set; and summarizing the detection data returned by the target media servers by taking the area to which the media server belongs as a summarizing dimension to obtain a second network performance detection data set. The method has the advantages that the same detection task is synchronously sent to the target media server while the detection task is sent to the target client, the consistency of detection data between the client and the media server and the detection data between the media servers on detection time is ensured, and the method has reference value in calculating the score. The target media server may be all or part of a preset set of media servers. The second network performance probe data set may be understood as a pre-constructed routing decision table between media servers.
For example, after receiving the detection task, a certain target media server d may determine a preset data packet sequence according to the detection parameter, respectively send a detection packet to each media server (a, b, c, and e) except d in a preset media server set (assumed to include a, b, c, d, and e) according to the preset data packet sequence, record a feedback condition of each media server, further calculate detection data, and report the detection data to the server. After receiving the probe data reported by the target media servers, the server may aggregate the probe data according to a time dimension of a preset time level (e.g., according to day, hour, or minute), and then summarize the probe data by using the area to which the media server belongs as a summarization dimension, so as to obtain a second network performance probe data set.
In some embodiments, the determining a first score corresponding to each available region by using a first preset scoring rule based on the first detection data and the second detection data includes: calculating first index values corresponding to the at least two network performance indexes corresponding to each available area according to the first detection data and the second detection data; and calculating the weighted sum or the weighted square sum of at least two first index values aiming at each available area to obtain a first score corresponding to each available area. The advantage of such setting is that the first score can be reasonably calculated, so that the first score can more accurately reflect the overall network performance of the routing path under the condition of adopting the current available area, and the distribution accuracy of the media server is further improved.
In some embodiments, the screening of the candidate regions from the plurality of available regions according to the first score comprises: and screening the preset number of available regions with the highest first score as candidate regions. Wherein the determining a second score corresponding to the candidate region pair by using a second preset scoring rule based on the first detection data, the second detection data and the third detection data comprises: calculating second index values respectively corresponding to the at least two network performance indexes corresponding to each candidate area pair according to the first detection data, the second detection data and the third detection data; and calculating the weighted sum or the weighted square sum of at least two second index values aiming at each candidate region pair to obtain a second score corresponding to each candidate region pair. The advantage of such setting is that the second score can be reasonably calculated, so that the second score can more accurately reflect the overall network performance of the routing path under the condition of adopting the current candidate region pair, and the distribution accuracy of the media server is further improved.
In some embodiments, the at least two network performance indicators include at least one of average response time, packet reception success rate, and network delay jitter. When the average response time is included, the corresponding first index value is determined according to the sum of the values of the average response time in the first detection data and the second detection data, and the corresponding second index value is determined according to the sum of the values of the average response time in the first detection data, the second detection data and the third detection data. When the success rate of receiving the data packet is included, a corresponding first index value is determined according to the product of the success rate values of receiving the data packet in the first detection data and the second detection data, and a corresponding second index value is determined according to the product of the success rate values of receiving the data packet in the first detection data, the second detection data and the third detection data. When network delay jitter is included, a corresponding first index value is determined according to the sum of network delay jitter values in the first detection data and the second detection data, and a corresponding second index value is determined according to the sum of network delay jitter values in the first detection data, the second detection data and the third detection data. The advantage of setting up like this is, can rationally calculate first index value and/or second index value, make corresponding first score and/or second score more accurate, promote the accuracy that media server distributes.
In some embodiments, the determining and allocating a target media server corresponding to the audio/video call event according to a media server existing in the target area includes: determining a target area with the lowest corresponding distribution cost in the target areas as an area to be distributed; and determining a target media server corresponding to the audio and video call event according to the media servers in the area to be distributed and distributing the target media server. The allocation cost may include network traffic cost, and the influence degree of the load of the media server on the performance of the media server. The advantage of setting up like this is, on the basis of guaranteeing network performance, compromise the distribution cost simultaneously to better adapt to the conversation environment of internationalization. When the target region is a pair of candidate regions, the allocation cost may be the sum of the allocation costs corresponding to the two candidate regions.
In some embodiments, further comprising: if the target area cannot be determined currently, determining a preset media server matched with client attribute information respectively corresponding to the calling party and the called party as a server to be allocated; if the matched preset media server cannot be inquired, determining the media server closest to the calling party and/or the called party as a server to be distributed; and taking the server to be distributed as a target media server corresponding to the audio and video call event and distributing. This has the advantage that the availability of the allocation scheme can be increased.
For example, when there is little or missing probe data, or an available area cannot be determined, or there are many blacklisted areas for the calling party and/or the called party (for example, areas blacklisted due to long-term poor network performance relative to the calling party and/or the called party), a situation that a target area cannot be determined may occur, for an international call environment, a fixed media server (a preset media server) may be directly specified for some specific countries to supplement the situation that the target area cannot be determined, so as to ensure availability, and specifically, a routing path corresponding to the preset media server may be written in a hard coding manner. For the absence of the preset media server, the media server can be selected for distribution based on the principle of proximity, and the availability is further ensured.
In some embodiments, an audio-video call in a multi-party group chat mode may also be supported, at this time, if there are multiple called parties, corresponding target areas may be determined for multiple groups of calling and called parties, and when there are at least two target areas corresponding to the called parties including candidate area pairs, it is ensured that the at least two candidate area pairs corresponding to the at least two called parties respectively and serving as the target areas are the same as candidate areas allocated to the calling party. That is, in the multiple routing paths from the calling party to the multiple called parties, the same area is used for establishing network connection with the calling party. The method has the advantages of reducing the forwarding times of the audio and video data and improving the communication efficiency.
Fig. 2 is a schematic flow chart of another media server distribution method according to an embodiment of the present invention, and fig. 3 is a schematic system flow chart of a media server distribution method according to an embodiment of the present invention, which can be understood by referring to fig. 2 and fig. 3. As shown in fig. 2, the method may include:
step 201, determining the detected client end ending the audio/video call as a target client end, recording client end attribute information corresponding to the target client end, and sending a detection task to the target client end and a target media server.
The detection task comprises detection parameters used for determining a preset data packet sequence, wherein the detection parameters comprise the number of detection packets, the sending interval of the detection packets and the size of the detection packets. The client attribute information includes geographic location, network type, and network service operator.
For example, the client that has just finished the call may be regarded as an active user, and user data of the active user is recorded, where the user data includes attribute information of the used client, so as to facilitate subsequent summarization of the probe data. And the target client determines a preset data packet sequence according to the detection parameters and sends a detection packet to the media server to obtain a detection result. And the target media server determines a preset data packet sequence according to the detection parameters and sends a detection packet to the media server to obtain a detection result.
Illustratively, the probe data includes data of network performance indicators, which include average response time (denoted as RTT), packet reception success Rate (denoted as Succ _ Rate), and network delay Jitter (denoted as Jitter).
And 203, detecting that the audio and video call event is triggered, and determining a plurality of available areas according to client attribute information respectively corresponding to a calling party and a called party.
For example, for an international call scenario, a global available area list may be obtained according to respective geographic locations of a calling party and a called party.
For example, first index values corresponding to the network performance indexes corresponding to the available areas may be calculated according to the first probe data and the second probe data.
For example, the first index values, respectively denoted as RTT1, Succ _ Rate1, and Jitter1, may be determined by the following expressions:
RTT1＝RTT_Initiator+RTT_buddy
Jitter1＝Jitter_Initiator+Jitter_buddy
Succ_Rate1＝Succ_Rate_Initiator*Succ_Rate_Buddy*100
wherein Initiator corresponds to the calling party and buddy corresponds to the called party. The RTT _ Initiator represents the value of RTT from the calling party to the corresponding available area, and the RTT _ buddy represents the value of RTT from the called party to the corresponding available area; the Jitter _ Initiator represents the value of Jitter from the calling party to the corresponding available area, and the Jitter _ buddy called party represents the value of Jitter from the calling party to the corresponding available area; the Succ _ Rate _ Initiator indicates the value of Succ _ Rate from the calling party to the corresponding available region, and the Succ _ Rate _ bucket called party indicates the value of Succ _ Rate to the corresponding available region.
The first Score, Score1, may be determined by the expression:
Score1＝(RTT1*RTT1_coef)^2+(Succ_Rate1*Succ_rate1_coef)^2+(Jitter1*Jitter1_coef)^2
wherein, RTT1_ coef represents the weight coefficient of RTT index in the first score, Succ _ rate1_ coef represents the weight coefficient of Succ _ rate index in the first score, and Jitter1_ coef represents the weight coefficient of Jitter index in the first score. The three weight coefficients may be configured according to factors such as network environment.
Illustratively, the available regions are sorted according to a first score, and a preset number of available regions with the highest score are selected as candidate regions.
For example, first, a second index value corresponding to the network performance index corresponding to each candidate region pair is calculated according to the first detection data, the second detection data and the third detection data corresponding to the candidate region pair.
For example, the second index values, denoted RTT2, Succ _ Rate2, and Jitter2, respectively, may be determined by the following expression:
RTT2＝RTT_Initiator_Region1+RTT_Region1_Region2+RTT_Buddy_Region2
Jitter2＝Jitter_Initiator_Region1+Jitter_Region1_Region2+
Jitter_Buddy_Region2
Succ_Rate2＝Succ_Rate_Initiator_Region1*Succ_Rate_Region1_Region2*
Succ_Rate_Buddy_Region2*10000
the Initiator corresponds to the calling party, the buddy corresponds to the called party, the Region1 represents a first candidate Region of the candidate Region pair that needs to be network-connected with the calling party, and the Region2 represents a second candidate Region of the candidate Region pair that needs to be network-connected with the called party. RTT _ Initiator _ Region1 represents a value of RTT from the calling party to the corresponding first candidate Region, RTT _ Region1_ Region2 represents a value of RTT from the first candidate Region to the second candidate Region, and RTT _ Buddy _ Region2 represents a value of RTT from the called party to the second candidate Region; the Jitter _ Initiator _ Region1 represents the value of Jitter from the calling party to the corresponding first candidate Region, the Jitter _ Region1_ Region2 represents the value of Jitter from the first candidate Region to the second candidate Region, and the Jitter _ budget _ Region2 represents the value of Jitter from the called party to the second candidate Region; the Succ _ Rate _ Initiator _ Region1 indicates the value of the Succ _ Rate from the calling party to the corresponding first candidate Region, the Succ _ Rate _ Region1_ Region2 indicates the value of the Succ _ Rate from the first candidate Region to the second candidate Region, and the Succ _ Rate _ bucket _ Region2 indicates the value of the Succ _ Rate from the called party to the second candidate Region.
The second Score2 may be determined by the expression:
Score2＝(RTT2*RTT2_coef)^2+(Succ_Rate2*Succ_rate2_coef)^2+(Jitter2*Jitter2_coef)^2
wherein RTT2_ coef represents a weight coefficient of the RTT index in the second fraction, Succ _ rate2_ coef represents a weight coefficient of the Succ _ rate index in the second fraction, and Jitter2_ coef represents a weight coefficient of the Jitter index in the second fraction. The three weighting coefficients may be configured according to network environment and other factors, and may be the same as or different from, and are generally the same as, the first score expression.
And step 212, taking the preset media server as a target media server corresponding to the audio and video call event and distributing.
And step 213, determining the media server closest to the calling party and/or the called party as a target media server corresponding to the audio and video call event and distributing.
The media server allocation method provided by the embodiment of the invention can be used for scoring based on a large amount of network detection data by combining three indexes of network delay, jitter and data packet receiving success rate, and selecting candidate routing schemes according to the score sorting, so that the accuracy is higher. For international calls with far geographic positions, delay caused by forwarding among media servers is considered, the method is more suitable for cross-regional route forwarding, and expansibility is stronger. And finally, selecting the optimal media server according to the cost and the score, and optimizing the cost while ensuring the call quality. For summary of the detection data, real-time detection data (such as minute level) can be adopted for main countries, when the network quality is poor due to the fact that a public network of a certain machine room is blocked or the machine room is in fault, such as abnormal power failure and the like, changes of networks in various areas can be rapidly identified, a routing decision table is immediately updated, the fault area is automatically removed, and a client is ensured to be always connected to the current optimal media server. User data acquisition, network data packet detection, detection data storage, acquisition of detection data and media server allocation form a complete link, during media allocation, a hard coded routing and a near selection scheme are provided, and high availability is guaranteed when the detection data link is abnormal.
