Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
At present, when a client establishes a TCP (Transmission Control Protocol) connection with a server, the client first sends a SYN (synchronization Sequence number) signal to the server, the server receives the SYN signal and then sends the SYN signal and an ACK (acknowledgement character) signal to the client, and the client starts a timer and sets a timeout value of the timer, which is usually set according to an RTT (Round-Trip Time) experience value. If the timer reaches the timeout value and no ACK signal returned by the client is received, the server repeatedly sends a SYN signal and an ACK signal to the client, starts the timer again and sets the timeout value of the timer, and the timeout value is usually set according to the index value of the last timeout value. Under the condition of poor network state, the server needs to send multiple SYN signals and ACK signals, at the moment, the timeout value is increased in an exponential increase mode, the timeout value is larger and larger, the time for the server to wait for the reply of the client is longer and longer, and the speed for establishing connection between the client and the server is slower.
Based on this, the method, the device and the server for establishing the TCP connection provided by the embodiments of the present invention can be applied to network connections of clients such as computers and mobile phones. For the convenience of understanding the embodiment, a detailed description will be first given of a method for establishing a TCP connection disclosed in the embodiment of the present invention.
First, an embodiment of the present invention provides a method for establishing a TCP connection, and as shown in fig. 1, the method includes the following steps:
step S102, if receiving a connection request from a client, sending a response signal corresponding to the connection request to the client; the connection request carries a client address of the client;
the client may be a mobile terminal device such as a computer and a mobile phone, and the server may be a device such as a server. The connection request may be a SYN signal sent by the client, and the response signal may be a SYN signal and an ACK signal sent by the server, so as to notify the client of the confirmation of the connection request signal. The client address of the client may be an IP (Internet Protocol) address of the client. Specifically, when a TCP connection is established, a client sends a connection request SYN signal to a server, which includes an IP address of the client, and after receiving the SYN signal, the server must confirm the SYN signal of the client, and simultaneously sends a response signal, which includes a SYN signal and an ACK signal.
Step S104, obtaining a communication delay corresponding to a client address which is saved in advance;
the communication delay may be RTT (Round-Trip Time), which is also an important performance indicator in a computer network, and represents the total delay experienced from the Time when the server sends data to the Time when the server receives an acknowledgement signal from the client. Since the connection request carries the client address of the client, the calculated RTT has the corresponding server address and client address when the server and the client are in communication connection, and thus the communication delay saved in advance can be set by the calculated RTT.
Step S106, starting a preset timer, and setting a timeout value of the timer according to the communication delay;
usually, the server sends the SYN signal and the ACK signal at the same time, and starts a preset timer, which can record the time from the sending of the signal to the receiving of the signal. The timeout value may be set according to the calculated RTT, i.e., the communication delay.
Step S108, based on the timeout value, a TCP connection is established with the client.
Specifically, after a preset timer is started, if the timing time of the timer exceeds a timeout value, the server side sends a response signal to the client side again until a TCP connection is established with the client side; in addition, after the server side sends signals for many times and the timer is overtime, the connection times of the server side exceeds a preset value, or the accumulated timing time of the timer exceeds preset time, and the connection between the server side and the client side fails.
The embodiment of the invention provides a method for establishing TCP connection, which comprises the steps of sending a response signal corresponding to a connection request to a client if the connection request from the client is received; the connection request carries a client address of the client; obtaining a communication delay corresponding to a client address which is stored in advance; starting a preset timer at the same time, and setting a timeout value of the timer according to the communication delay; based on the timeout value, a TCP connection is established with the client. In the method, the timeout value of the started timer is set through the communication delay of the prestored server address and the corresponding client address, so that the condition that the time for the server to wait for the reply of the client is longer and longer due to the fact that the timeout value is larger and larger under the condition that the network state is poorer is avoided, and the speed of establishing the TCP connection between the client and the server is improved.
The embodiment of the invention provides another method for establishing TCP connection, which is realized on the basis of the method of the embodiment; this embodiment mainly describes a specific implementation process of the step of obtaining a pre-stored communication delay corresponding to the client address (implemented by step S204), as shown in fig. 2, the method includes the following steps:
step S202, if a connection request from the client is received, a response signal corresponding to the connection request is sent to the client; the connection request carries a client address of the client;
step S204, obtaining communication time delay corresponding to the address of the client from a pre-established database;
the pre-established database may store a plurality of communication delays corresponding to a plurality of server addresses and a plurality of client addresses when establishing a connection;
wherein, the database is established by the following method: acquiring a historical communication record of a client corresponding to the client address, extracting communication time delay from the historical communication record, and correspondingly storing the extracted communication time delay and the client address into a database;
because the connection request carries the client address of the client, the historical communication record of the client, such as the communication record with the server in the last month, can be obtained through the client address; the communication record may include information such as communication delay when establishing a connection with one or more servers. The communication delay when the connection is established with the current server can be extracted from the historical communication record, and the extracted communication delay and the address of the client are correspondingly stored in the database.
For the above step S204, referring to a flowchart of a method for obtaining communication delay shown in fig. 3, a specific implementation process of the step of obtaining communication delay corresponding to the address of the client from a pre-established database is included in the method, where the method includes the following steps:
step S301, if the communication time delay corresponding to the client address is not obtained from the database, determining a first area range to which the client address belongs;
the first area range to which the client address belongs may be an IP address near a region where the client address is located, for example, the first area range may be an IP address of another client in a range of one hundred meters in the region where the client address is located.
Step S302, obtaining a communication delay corresponding to the client address in the first area range from the database, and determining the communication delay as the communication delay corresponding to the client address of the client.
If the communication delay corresponding to the client address is obtained through the first area range, the communication delay can be determined as the communication delay corresponding to the client address of the client; meanwhile, the communication delay and the client address can be correspondingly stored in the database so as to meet the richness and the real-time performance of the database.
Further, the database also stores: the server address of the server which communicates with the client corresponding to the client address in the historical communication record; correspondingly storing the address of the server, the address of the client and the communication delay; referring to another method flowchart for obtaining communication delay shown in fig. 4, a specific implementation process of the step of obtaining communication delay corresponding to the address of the client from a pre-established database includes the following steps:
step S401, obtaining the address of the server receiving the connection request;
step S402, obtaining the communication time delay corresponding to the client address and the server address from the pre-established database, and determining the communication time delay as the communication time delay corresponding to the client address of the client.
The communication delay represents the delay of the connection between the server and the client, so that the communication delay stored in the database not only needs to have the corresponding client address, but also can have the corresponding server address; specifically, the server address of the server that receives the connection request may be directly acquired, then the communication delay corresponding to the client address and the acquired server address is acquired from a pre-established database, and the communication delay is determined as the communication delay corresponding to the client address of the client.
With reference to the above step S402, referring to another flowchart of the method for obtaining communication delay shown in fig. 5, a specific implementation process of the step of obtaining communication delay corresponding to the client address and the server address from a pre-established database is shown in fig. 5, where the method includes the following steps:
step S501, if the communication time delay corresponding to the client address and the server address cannot be obtained from the database, determining a second area range to which the client address belongs;
the second area range to which the client address belongs may be other IP addresses near the area where the client address is located, for example, the IP addresses of other clients within a range of one hundred meters in the area where the client address is located.
Step S502, obtaining communication time delay corresponding to the address of the server and the address of the client in the second area range from the database;
after acquiring other client addresses in the second area range, the communication delay corresponding to the server address and the client address in the second area range can be searched in the database.
Step S503, if the communication time delay corresponding to the address of the server and the address of the client in the second area range is not obtained from the database, determining a third area range to which the address of the server belongs;
the third area range to which the server address belongs may be other IP addresses near the area where the server address is located, for example, the third area range may be IP addresses of other servers in a range of one hundred meters in the area where the server address is located.
Step S504, a communication delay corresponding to the address of the client in the second area range and the address of the server in the third area range is obtained from the database.
After acquiring the addresses of other clients in the second area range and the IP addresses of other servers in the third area range, the corresponding communication delay may be acquired from the database.
Step S206, starting a preset timer, and setting a timeout value of the timer according to the communication delay;
step S208, based on the timeout value, a TCP connection is established with the client.
In addition, the method also comprises the implementation process of the step of updating the database, and the implementation process comprises the following steps of:
if the updated historical communication record of the client corresponding to the client address is obtained, extracting the updated communication delay from the updated historical communication record;
and if the updated communication delay is smaller than the communication delay corresponding to the client address recorded in the database, correspondingly storing the updated communication delay and the client address into the database.
Usually, the same client and the same server may have multiple communication records, and if the communication delay between the same client and the same server is already stored in the database and then the client and the server are in communication connection, the communication delay is updated to the history record. And meanwhile, comparing the updated communication delay with the historical communication delay stored in the database before, if the updated communication delay is smaller than the communication delay corresponding to the client address recorded in the database, correspondingly storing the updated communication delay and the client address into the database so as to ensure the real-time property of the database. In addition, if the updated communication delay is larger than the communication delay corresponding to the client address recorded in the database, no processing is performed.
In the method, corresponding communication time delay is extracted through a historical communication record of a client; establishing a database according to the address of the client, the address of the server and the communication delay corresponding to the client and the server; by means of configuration, communication time delay corresponding to a client address and a server address which are establishing connection in a database is obtained to set a timeout value of a started timer, and under the condition that a network state is poor, the condition that the time for the server to wait for the client to reply is longer and longer due to the fact that the timeout value is larger and larger is avoided, and the speed of establishing TCP connection between the client and the server is improved.
The embodiment of the invention provides another method for establishing TCP connection, which is realized on the basis of the method of the embodiment; this embodiment focuses on a specific implementation process of the step of establishing a TCP connection with the client based on the timeout value (specifically implemented by steps S608-S610), as shown in fig. 6, the method includes the following steps:
step S602, if a connection request from a client is received, a response signal corresponding to the connection request is sent to the client; the connection request carries a client address of the client;
step S604, obtaining a communication delay corresponding to the address of the client terminal which is saved in advance;
step S606, starting a preset timer, and setting a timeout value of the timer according to the communication delay;
step S608, when the timing duration of the timer is less than the timeout value, receiving a response signal returned by the client, and determining that the TCP connection with the client is successfully established;
the method comprises the steps that a preset timer is started while a response signal corresponding to a connection request is sent to a client by a server, the timer keeps timing until a signal for confirming connection sent by the client is received, the server receives the signal for confirming connection sent by the client under the condition that the timing duration of the timer is smaller than a timeout value, the timer stops timing, and meanwhile, the TCP connection establishment success with the client is confirmed.
Step S610, if the timing duration of the timer reaches the timeout value, the response signal returned by the client is not received, and the step of sending the response signal corresponding to the connection request to the client is continuously executed until the response signal returned by the client is received or the preset condition is met;
if the timing duration of the timer reaches the timeout value, the server does not receive a connection confirmation signal sent by the client, and the timer stops timing; and then the server side continuously sends a response signal corresponding to the connection request to the client side, and simultaneously starts the timer again until the server side receives a response signal returned by the client side, and stops timing. Or under the condition that the server side does not receive the response signal returned by the client side all the time, stopping connection and displaying connection failure after the preset condition is met.
Wherein the preset conditions include: after receiving the connection request, the number of times of sending the response signal reaches a preset number threshold, or the time interval between the current time and the first time of sending the response signal meets a preset time threshold.
The time threshold and the time threshold may be set according to a history record of a specific client, for example, the time threshold may be 10, 15, etc.; the time threshold may be 1 minute, 5 minutes, etc. Specifically, after receiving the connection request, the server sends a response signal to the client, starts a timer to start timing, and if the timing duration reaches a timeout value, the server does not receive a connection confirmation signal sent by the client, and sends the response signal to the client again until the number of times of sending the response signal reaches a preset number threshold, the server stops the connection, and displays that the connection fails. Or, if the timing duration reaches the timeout value, the server does not receive a connection confirmation signal sent by the client, the server sends a response signal to the client again, starts the timer again to start timing, and stops connection and displays that the connection fails until the time interval between the current time and the time when the response signal is sent for the first time meets the preset time threshold.
In the method, the connection is directly established by comparing the timing duration of the timer with the timeout value under the condition that the timing duration is less than the timeout value; under the condition that the timing duration is greater than the timeout value, the timer is started again, the preset condition is set, and the connection is terminated in time.
