Detailed Description
In order to enable those skilled in the art to better understand the technical solutions of the present disclosure, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings.
It should be noted that the terms "first," "second," and the like in the description and claims of the present disclosure and in the foregoing figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the disclosure described herein may be capable of operation in sequences other than those illustrated or described herein. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.
It should be further noted that, the user information (including, but not limited to, user equipment information, user personal information, etc.) and the data (including, but not limited to, data for presentation, analyzed data, etc.) related to the present disclosure are information and data authorized by the user or sufficiently authorized by each party.
One connection establishment method in the related art is described below.
In the related art, if a connection is established between a client and a server for the first time under the current network, the client may randomly select n access points from a given set of access points, so that the n access points start to connect in parallel for racing, where n is any positive integer. In the connection racing process, whenever the client determines that there is an access point whose processing time is more than the automatic timeout limit defined by the default of the transmission protocol of the access point, the client eliminates the access point and selects a new access point from a given set of access points to participate in the connection racing in parallel until there is a target access point to complete connection and handshake between the client and the server.
If the client and the server are not first connected under the current network, the client acquires the target access point successfully connected last time from the database in the first round of connection racing stage, and directly uses the target access point to establish connection with the server. If the processing time of the target access point exceeds the default automatic timeout limit value of the access point or the connection establishment of the target access point fails, the client enters a second connection racing stage. Randomly selecting n access points from the rest of the access points in a given group of access points, simultaneously starting connection racing, and continuously executing the process of establishing connection for the first time until a new target access point exists to complete connection and handshake between the client and the server.
In the related art, a new access point needs to be supplemented after the access point connection or handshake reaches the automatic timeout limit value, and the automatic timeout limit value usually takes a long time, so that the problem of long time for establishing the whole connection exists. In addition, for the connection which is not established for the first time, because the connection and handshake time consumption index of each access point may change with time, when the index of the target access point is poor, there is no opportunity to timely supplement other access points to participate in connection racing, and the overall time consumption of establishing the connection is also affected.
In order to solve the above-mentioned problems, the present disclosure provides a connection establishment method, which can be applied to an application environment as shown in fig. 1. Wherein the terminal 110 interacts with the server 120 through a network. The terminal 110 has an application installed therein. The application may be, but is not limited to, social, instant messaging, electronic commerce, short video, etc. applications. The server 120 has deployed therein an application platform that supports the operation of the application. Terminal 110 is preconfigured with a set of access points. When the terminal 110 needs to establish a connection with the server 120, the terminal 110 obtains at least one access point from a group of access points, and constructs a candidate access point set. The process of acquiring individual access points by the terminal 110 is time consuming in the process of establishing a connection for the access points. The processing time consumption is compared to a first time length threshold. And when the processing time consumption reaches a first time length threshold value, acquiring a new access point, adding the new access point to the candidate access point set, and enabling the new access point to participate in connection racing. The terminal 110 repeats the above procedure for the new access point until the first target access point exists in the candidate access point set to successfully establish a connection between the terminal 110 and the server 120.
The terminal 110 may be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices. The server 120 may be implemented as a stand-alone server or as a server cluster composed of a plurality of servers.
Fig. 2 is a flowchart illustrating a connection establishment method according to an exemplary embodiment, and as shown in fig. 2, the connection establishment method is used in a terminal and includes the following steps.
In step S210, a set of candidate access points is determined.
Wherein the access point may be characterized by an IP (Internet Protocol ) address, port number, access point identification, etc. The candidate access point set includes at least one access point participating in connection racing. The at least one access point may be derived by the client from a pre-configured set of access points in a pre-set access point selection manner, e.g., in a random selection, a specified sequential selection, etc. The preconfigured access points may include access points under a variety of transport protocols, including, for example, TCP (Transmission Control Protocol ), UDP (User Datagram Protocol, user datagram protocol), qic (Quick UDP Internet Connection, UDP-based low latency internet transport layer protocol), and the like.
Specifically, when the client needs to establish connection with the server, the client acquires at least one access point from a preset group of access points according to a preset access point selection mode, and obtains a candidate access point set. The connection establishment in this embodiment may be a first connection establishment or a non-first connection establishment under the current network. The kind of connection established may be a short connection or a long connection.
In step S220, the process of acquiring the access point is time-consuming in the process of establishing a connection by the access point.
The processing time can be represented by any one of connection establishment time, handshake time and the like. When the access point needs to make multiple connections and handshakes, the processing time consumption may be each connection time consumption or each handshake time consumption. By providing multiple processing time consuming, the flexibility of use of the client to establish a connection, as well as compatibility under different transport protocols, may be improved.
Specifically, the client sends data packets to the server through each access point, so that each access point can establish a connection between the client and the server. In the process of establishing connection of each access point, the client acquires the current processing time of each access point in real time or at fixed time.
In step S230, when the processing time spent for the first access point in the candidate access point set reaches the first time length threshold, a new access point is acquired.
Wherein the first time length threshold is less than the auto timeout constraint. The auto-timeout limit may refer to a time-consuming limit defined by a default for the transmission protocol, e.g., for the TCP transmission protocol, the access point connection timeout is determined after the default will connect or handshake for more than 15 seconds. The first time length threshold may be a pre-configured fixed value, e.g., pre-configured to be 2 seconds; it is also possible to use a threshold value derived from the processed time consumption of several times of history, for example, using the percentile values of P95, P99.9, etc. The P95 and P99.9 means that the response time consumption of the server end is arranged from small to large, the time consumption value in the sequence of 95% is the P95 value, and the time consumption value in the sequence of 99.5% is the P99.5 value.
The first access point refers to an access point that is time consuming in current processing and reaches a first time length threshold, and the number of the access points can be one or more. When the number of the first access points is one, acquiring a new access point corresponding to the first access point; when the number of the first access points is plural, a new access point corresponding to each first access point may be acquired.
The new access points may refer to access points that have not participated in connection racing, and for each first access point, one or more new access points may be acquired.
Specifically, after acquiring the processing time consumption of each access point, the client compares the processing time consumption with a first time length threshold. When the time consuming process of acquiring the existence of the first access point in the respective access points has reached the first time length threshold, the client may acquire a new access point from a preconfigured set of access points or a preconfigured backup access point, or the like.
In step S240, a new access point is added to the candidate set of access points until a first target access point is determined from the candidate set of access points, the first target access point being used to successfully establish a connection with the server.
Specifically, the client adds a new access point to the candidate access point set, updates the candidate access point set, and detects the time consumption of processing each access point in the current candidate access point set according to the content described in steps S210 to S230 until a first target access point exists in the candidate access point set to successfully establish connection between the client and the server. The client may stop the connection racing and use the data transfer between the first target access point and the server.
In the connection establishment method, when the time consumption of the connection establishment process of the access points in the candidate access point set reaches the first time length threshold, a new access point is acquired, the new access point is added into the candidate access point set, and the new access point is connected with other access points in the candidate access point set in parallel to perform racing until the connection between the first target access point and the server is successfully established from the candidate access point set. The first time-length threshold is less than the auto-timeout constraint by pre-configuring the first time-length threshold. The access point can supplement the new access point to participate in connection racing without waiting for the automatic timeout limit value, so that the whole connection establishment time of the connection can be ensured to be completed in a short time, and the connection establishment efficiency is improved.
In an exemplary embodiment, in step S220, when the processing time spent for the first access point in the candidate access point set reaches the first time length threshold, acquiring a new access point includes: when the time consumption of the processing of the first access point existing in the candidate access point set reaches a first time length threshold value, acquiring the number of access points existing in the candidate access point set; and when the number of the access points does not reach the number threshold, acquiring a new access point.
The number threshold refers to the maximum number of access points that can be accommodated in the candidate access point set. The number threshold may be a pre-configured fixed value, e.g., 10 pre-configured number thresholds; the dynamic change value obtained according to the operation condition of the server may be, for example, a mapping relationship between the response time and the threshold value may be established in advance. And searching a threshold corresponding to the current response time from the mapping relation to serve as a current quantity threshold.
Specifically, when the processing time of each time the client determines that the first access point exists reaches the first time length threshold value, the client acquires the number of access points currently existing in the candidate access point set. The number of access points acquired is compared to a number threshold. And when the number of the access points is smaller than the number threshold, acquiring a new access point, and adding the new access point to the candidate access point set. Accordingly, when the number of access points is greater than or equal to the number threshold, the client stops acquiring new access points.
Illustratively, the current candidate access point set includes three access points, access point 1, access point 2, and access point 3. The access point 1 is determined to be the first access point. If the number threshold is 10, the client may acquire a new access point 4 and add the access point 4 to the candidate set of access points, such that the candidate set of access points includes 4 access points. If the number threshold is 3, the client stops acquiring new access points.
In the embodiment, by configuring the number threshold of the access points, a plurality of access points can perform connection racing in the same time period, so that the success rate and the efficiency of connection establishment are improved; in addition, by controlling the maximum number of access points that are simultaneously performing connection racing, excessive operating pressure on the server can be avoided.
In an exemplary embodiment, the method further comprises: and removing the first access point from the candidate access point set when the processing time consumption corresponding to the first access point reaches the automatic timeout limit value.
Specifically, after the client determines that the processing time consumption of the first access point reaches the first time threshold, the client may enable the first access point to continue to establish a connection between the client and the server until the current processing time consumption of the client for obtaining the first access point reaches the automatic timeout limit value, or the connection establishment of the first access point fails. The client removes the first access point from the set of candidate access points to eliminate the first access point.
In this embodiment, after it is determined that the time consumption of the processing of the access point reaches the first time threshold, on the premise of supplementing a new access point, connection establishment is further performed by the first access point, so that the number of access points that process connection simultaneously can be increased without obviously increasing the server pressure, and the success rate and the efficiency of connection establishment are improved.
In an exemplary embodiment, after determining the first target access point from the candidate access point set in step S240, the method further includes: acquiring a second duration threshold; and when the second target access point is determined to successfully establish the network connection from the candidate access point set within the second duration threshold, determining the access point used for data transmission from the first target access point and the second target access point.
Wherein the second duration threshold may be a pre-configured fixed value, e.g., configuring the second duration threshold to be 30 milliseconds; or a dynamic value obtained according to the running condition of the current server, for example, a mapping relation between time delay and a time length threshold is pre-established. And searching a time length threshold corresponding to the current time delay from the mapping relation, and taking the threshold as a second time length threshold.
Specifically, when a preset set of access points has access points under multiple transmission protocols, in the related art, in each connection racing stage, the access points can be sequentially selected from the access points corresponding to each transmission protocol, so that the access points under each transmission protocol have the same opportunity to establish connection. For example, there are two transmission protocols, TCP and QUIC, then access points may be selected in the order QUIC-1, TCP-1, QUIC-2, TCP-2, … QUIC-n, TCP-n, thereby ensuring that each connection racing phase, access points under the respective transmission protocols have the opportunity to participate in the connection racing. However, since the connection establishment of each access point is successively performed at the beginning, the method in the related sampling technology cannot enable the access points under each transmission protocol to participate in the connection racing fairly, and thus cannot ensure that the access points with better performance can be acquired.
In view of the above, in this embodiment, after the client acquires the first target access point and successfully establishes the connection, the first target access point may not be immediately used for data transmission. The client continues to make connection racing for other access points in the candidate access point set than the first target access point. If the second target access point is acquired within the second time threshold from the first target access point determined by the distance, so that the client and the server are successfully connected, one access point is selected from the first target access point and the second target access point as the access point for final data transmission according to a preset access point determination mode. Wherein the number of second target access points may be one or more. The preset access point determining mode can be random selection, selection of an access point with better performance, and the like.
Further, if the second target access point is not acquired within the second time threshold from the first target access point determined by the distance, so that the client and the server are successfully connected, the client adopts the first target access point as an access point for final data transmission.
In this embodiment, after the access points with successful connection are obtained for the first time, an access point determining policy based on delay determination is adopted to obtain more access points with successful connection, and one access point is selected from all the access points with successful connection as an access point for subsequent data transmission, so that the speed-race fairness among the access points can be improved.
In an exemplary embodiment, determining an access point for data transmission from a first target access point and a second target access point includes: acquiring a first time delay of a first target access point and a second time delay of a second target access point; when the first time delay is greater than the second time delay, adopting a second target access point to transmit data; and when the second time delay is greater than or equal to the first time delay, adopting the first target access point to transmit data.
The delay may be characterized using RTT (Round-Trip Time), among others. The round trip delay represents the delay that is experienced in total from the time the sender (client) sends data to the time the sender receives an acknowledgement from the receiver (server).
Specifically, after the client obtains the second target access point within the second duration threshold, the client may obtain a first time delay corresponding to the first target access point and a second time delay corresponding to the second target access point. The client compares the first delay with the second delay. And when the first time delay is greater than the second time delay, a communication channel is established between the client and the server by adopting the second target access point, so that the client and the server perform data transmission through the second target access point. When the first time delay is smaller than the second time delay, a communication channel is established between the client and the server by adopting the first target access point, so that the client and the server perform data transmission through the first target access point. When the first time delay is equal to the second time delay, one of the first target access point and the second target access point can be randomly selected for data transmission.
In this embodiment, after the access points with successful connection are obtained for the first time, more access points with successful connection are obtained by adopting delay determination and access point determination strategies based on time delay, and one with smaller time delay is selected from all the access points with successful connection as the access point of subsequent data transmission, so that the access point with better performance can be obtained therefrom, thereby being beneficial to optimizing the process of subsequent data transmission.
In an exemplary embodiment, obtaining the second time period threshold includes: acquiring a first time delay of a first target access point; and determining a second duration threshold according to the first time delay and a preset adjusting parameter value.
Wherein the adjustment parameter value refers to a value for adjusting the first delay. The adjustment parameter value may be a pre-configured fixed value; or a dynamically changing value determined according to the running condition of the current server, for example, if the running condition of the current server is better, an adjusting parameter value can be set to make the second duration threshold larger; if the current server is operating in a normal manner, then an adjustment parameter value may be set to make the second duration threshold smaller.
In particular, the second duration threshold may be derived based on a first delay of the first target node. And the client acquires the first time delay after acquiring the second time threshold. And processing the first time delay and the adjustment parameter value based on a preset operation mode to obtain a second duration threshold. For example, the adjustment parameter value is a fixed percentage, then the product of the first time delay and the percentage may be obtained as the second time duration threshold. The adjustment parameter value is a fixed value, then the ratio of the first time delay and the adjustment parameter value may be obtained as the second time duration threshold. The adjustment parameter value is an adjustment delay value determined according to the running condition of the current server, and then the difference between the first delay value and the adjustment delay value can be obtained as a second duration threshold.
In this embodiment, the duration threshold for the client to continue waiting is determined based on the time delay of the access point successfully connected for the first time, so that the waiting duration of the client better accords with the time delay characteristic of the access point, and thus a more reasonable waiting duration can be provided.
Fig. 3 is a flowchart illustrating a connection establishment method according to an exemplary embodiment, which is applied to a terminal, and includes the following steps.
In step S302, when the client needs to establish a long connection with the server, a preset number of access points are acquired from a preset group of access points, and the preset number of access points are added to the candidate access point set.
The preset number of access points may be determined according to the number of connection establishment times under the current network. For example, if a connection is first established under the current network, multiple access points may be acquired from a set of access points in random or interleaved order according to the transmission protocol as mentioned in the above embodiment. If the connection is not established for the first time under the current network, the last access point used last time at the current time can be obtained.
In step S304, the process of acquiring the access point is time-consuming in the process of establishing a connection by the access point. The processing time can be represented by any one of connection establishment time and handshake time.
In step S306, when the processing time consumed for the first access point existing in the candidate access point set reaches the first time length threshold, the number of access points existing in the candidate access point set is obtained. Wherein the first time length threshold may be determined using a P95 percentile value (e.g., 1 second).
In step S308, when the number of access points does not reach the number threshold, a new access point is randomly acquired from the list of candidate access points. Adding the new access point to the candidate set of access points. Wherein the number threshold may be 10. Accordingly, when the number of access points reaches the number threshold, acquiring a new access point is stopped, and connection establishment is continued by using the access points in the current candidate access point set.
Further, for the first access point, the first access point may be continuously connected to perform the connection racing until the processing time consumption corresponding to the first access point reaches the automatic timeout limit value, and the first access point is removed from the candidate access point set.
Further, for the non-first connection establishment of the current network, when the time consumed for processing the access point successfully connected last time reaches the first time length threshold, a new access point can be immediately supplemented. However, for subsequent connection racing procedures, new access points may be replenished and access points that reached the automatic connection limit may be removed from the candidate set of access points when the processing time of each access point reaches the automatic timeout limit. In this way, less access points may be used for non-first connection establishment procedures, so as to relieve the server of the long connection establishment as a whole.
In step S310, it is determined whether a first target access point exists at present to enable the client and the server to successfully establish a connection, if so, step S312 is continued; otherwise, repeating the steps S304-S310.
In step S312, a ratio of the first delay of the first target access point to the preset adjustment parameter value is obtained as the second duration threshold. The adjustment parameter value may be 4.
In step S314, when the distance is within the second time threshold from the first target access point, the second target access point is determined from the candidate access point set to enable the client and the server to establish connection successfully, and the second time delay of the second access point is obtained.
In step S316, an access point for data transmission is determined from the first target access point and the second target access point according to the first delay and the second delay. Specific determination means may refer to the above-described embodiments, and will not be described in detail herein.
Fig. 4a and 4b show a comparison of the determination of the first target access point in a manner of the related art with the determination of the first target access point in a manner of steps S302 to S310. Assuming that the processing of the access points SP1-SP6 takes time to reach an automatic timeout limit (e.g., 15 seconds) for a non-first established connection until the access point SP7 connection is successful.
Fig. 4a shows a schematic diagram of acquiring the first target access point by a method in the related art, and as can be seen from fig. 4a, it is necessary to wait for 30 seconds to acquire SP7, and wait for 31 seconds to complete the connection establishment in the related art.
Fig. 4b shows a schematic diagram of acquiring the first target access point by the method in this embodiment, and as can be seen from fig. 4b, in this embodiment, SP7 can be acquired by waiting for 6 th second, and the connection can be completed by waiting for 7 th second.
Fig. 5a and 5b show two comparison diagrams of determining the end-use access point in a related art manner, and in a manner of steps S310 to S316.
Fig. 5a shows a comparative schematic of different transport protocols with the same start time. As shown in fig. 5a, qic 1 is the first target access point. If the related art method is adopted, QUIC1 is used for data transmission. However, in this embodiment, the second preset time period is 40 milliseconds. Although QUIC1 completes the handshake first, the TCP access point completes the handshake within the second duration threshold, i.e., at 180 milliseconds. Whereas the handshake RTT (90 ms) of the TCP access point is significantly smaller than the handshake RTT (160 ms) of quitc 1, the TCP access point will be used for data transmission.
Fig. 5b shows a comparative schematic of the same transmission protocol, different start times. As shown in fig. 5b, qic 1 is the first target access point. If the related art method is adopted, QUIC1 is used for data transmission. However, in this embodiment, the second preset time period is 40 milliseconds. While QUIC1 completes the handshake first, QUIC2 completes the handshake within the second duration threshold, i.e., 180 milliseconds. Whereas the handshake RTT (100 ms) of quitc 2 is significantly smaller than the handshake RTT (160 ms) of quitc 1, therefore quitc 2 will eventually be used for data transmission.

The steps are not strictly limited to the order of execution unless explicitly recited herein, and the steps may be executed in other orders.
