Detailed Description
In order to make the aforementioned objects, features and advantages of the present application more comprehensible, embodiments accompanying the drawings are described in detail below.
To facilitate understanding of the technical solutions provided in the embodiments of the present application, refer to the application scenario embodiment shown in fig. 1, where the method for switching a transmission protocol provided in this embodiment may be applied to the client 10.
In practical application, the client 10 may send heartbeat request information to the server 20 according to a preset period, so that the server may send response information in time after receiving the heartbeat request information. If the network state is active, the server 20 may send a response message to the client 10 in time, and the client 10 determines that the response message is received within a preset time, and continues to transmit data using the current first transmission protocol without switching the transmission protocol. If the network status is in an inactive state, the server 20 may not be able to timely send the response message to the client 10, and the client 10 determines that the response message is not received within the preset time, and performs the transmission protocol switching, and performs the data transmission using the second transmission protocol.
Those skilled in the art will appreciate that the block diagram shown in fig. 1 is only one example in which embodiments of the present application may be implemented. The scope of applicability of the embodiments of the present application is not limited in any way by this framework.
It is noted that the client 10 may be hosted by a terminal, which may be any user equipment now existing, developing, or later developed that is capable of interacting with each other through any form of wired and/or wireless connection (e.g., Wi-Fi, LAN, cellular, coaxial cable, etc.), including but not limited to: smart wearable devices, smart phones, non-smart phones, tablets, laptop personal computers, desktop personal computers, minicomputers, midrange computers, mainframe computers, and the like, either now in existence, under development, or developed in the future. The embodiments of the present application are not limited in any way in this respect. It should be further noted that the server 20 in the embodiment of the present application may be an example of an existing, developing or future-developed device capable of data transmission and reception. The embodiments of the present application are not limited in any way in this respect.
Based on the above description, the following describes, with reference to the accompanying drawings, a transport protocol switching method provided in an embodiment of the present application, where as shown in a flowchart of a method shown in fig. 2, the method may be applied to a client, and the method may include:
s201: and sending heartbeat request information to the server through a first transmission protocol.
In this embodiment, the client defaults to data transmission using the first transmission protocol, and may send heartbeat request information to the server in real time or according to a preset period during the data transmission process, so as to monitor changes in the current network state. The heartbeat request information comprises the identification of the client, so that the server can acquire the client to which the heartbeat request information received by the server belongs.
Wherein the first transport protocol may be a TCP protocol, which is a connection-oriented, reliable process-to-process communication protocol. The TCP protocols can provide a duplex service, i.e. data can be transmitted in both directions at the same time, and each TCP protocol has a sending buffer and a receiving buffer for temporarily storing data. The first transmission protocol may also be a UDP protocol, which is a connectionless and reliability-uncertain transmission protocol that is located in a transmission layer with a TCP protocol, and although reliability cannot be guaranteed, delay is small in a data transmission process, and data transmission efficiency is high.
S202: determining whether response information sent by the server after receiving the heartbeat request is received within a preset time, if not, executing S203; if so, S204 is performed.
It can be understood that, if the network status is more active, the server may send a response message to the client in time, which indicates that the client may receive the response message sent by the server within the preset time, and then S204 is performed. If the network state is an inactive state, the server cannot timely send or cannot send response information to the client, and the client cannot receive the response information sent by the server within the preset time, then S203 is executed.
The preset time may be set according to an actual application situation, for example, 1 second, 2 seconds, and the like, and this embodiment is not limited herein.
S203: and switching to a second transmission protocol, and transmitting data by using the second transmission protocol.
That is, if the client does not receive the response message sent by the server within the preset time, the client switches to the second transmission protocol, so as to transmit data by using the second transmission protocol. Wherein the first transmission protocol and the second transmission protocol are different transmission protocols. It is to be understood that the second transport protocol may be a UDP protocol when the first transport protocol is a TCP protocol, and a TCP protocol when the first transport protocol is a UDP protocol. That is, the first transport protocol and the second transport protocol are switched between the TCP protocol and the UDP protocol.
It should be noted that, when data transmission is performed by using the TCP protocol, because the TCP protocol is a connection-oriented protocol, before data transmission is performed by using the TCP protocol, the client needs the server to establish a connection, specifically:
1) and sending a connection establishment request to the server.
In this embodiment, when the client performs data transmission by using the TCP protocol, a connection establishment request is first sent to the server, where the connection establishment request includes a first sending sequence number. Specifically, the client sends a synchronization Sequence number (SYN) message to the server, where the SYN message carries a first sending Sequence number seq ═ x.
2) And receiving first reply information sent by the server after receiving the connection establishment request.
After receiving a setup request sent by a client, a server sends first reply information to the client, wherein the first reply information comprises a second sending sequence number and a first confirmation signal, and the first confirmation sequence number is equal to the first sending sequence number plus 1. Specifically, the server replies a SYN + ACK message to the client, where the second sending sequence number seq ═ y in the SYN message, and the first acknowledgement sequence number ACK ═ x +1 in the ACK message.
3) And sending the second reply message to the server to realize the connection establishment with the server.
And the client sends second reply information to the server after receiving the first reply information sent by the server, wherein the second reply information comprises a second confirmation signal, and the second confirmation signal is equal to the second sending sequence number increased by 1. Specifically, the client sends an ACK message to the server, where the ACK message includes the second acknowledgement signal ACK ═ y + 1.
Through the signaling interaction, the client and the server successfully establish connection, and then data transmission can be carried out by utilizing a TCP protocol.
S204: the data transmission is performed using the first transmission protocol.
And if the response information sent by the server is received within the preset time, continuing to use the first transmission protocol for data transmission.
It can be understood that the UDP protocol is a connectionless protocol, the transmission process is unreliable, packet loss occurs, and the like, and in order to ensure that the packet loss request can be known when the UDP protocol is used for transmission, the UDP protocol and the KCP protocol can be used in combination, and data transmission is performed by using the UDP protocol and the KCP protocol. Wherein the kcp protocol is a reliable transport layer protocol of the transport layer. Specifically, this can be achieved by:
1) and adding a sequence number field in the data to be transmitted, wherein the sequence number field is used for representing the sequence of each data to be transmitted.
2) And sending the data to be transmitted including the sequence number field to the server.
In this embodiment, before data transmission, the client adds a sequence number field to the data to be transmitted, where the sequence number field is used to indicate the sequence of each data to be transmitted. Specifically, the sequence number field is sequentially increased according to the transmission order of each data to be transmitted. And meanwhile, the server which adds the sequence number field and transmits the data to be transmitted.
3) And receiving confirmation information sent by the server, wherein the confirmation information comprises a sequence number field.
After receiving the data to be transmitted sent by the client, the server extracts the sequence number field from the data to be transmitted, generates confirmation information and sends the confirmation information to the client so as to inform the client that the data to be transmitted is correctly received. Because the confirmation information includes the sequence number field, the client can confirm that the server has received the data to be transmitted corresponding to the sequence number field according to the sequence number field.
4) And determining whether to retransmit the data according to the sequence number field in the data to be transmitted and the sequence number field in the confirmation information.
It can be understood that, since the sequence number field in the to-be-transmitted data is the same as the sequence number field in the acknowledgement information, after the client receives the acknowledgement information, it can determine which to-be-transmitted data is lost according to the sequence number field in the to-be-transmitted data sent by the client and the sequence number field in the acknowledgement information, and then determine data retransmission. For example, the client sends the data to be transmitted with sequence number fields 1, 2, 3, 4, and 5 to the server, but if the sequence number field of the received acknowledgement information is 1, 2, 4, and 5, it indicates that the data to be transmitted with sequence number field 3 is not correctly received by the server, and the data to be transmitted with sequence number field 3 may be retransmitted.
Based on the above description, the client sends heartbeat request information to the server based on the currently used first transmission protocol to check whether the current network status is in an active state. If the current network state is in an active state, the server may send a response message to the client within a preset time. And when the client determines that the corresponding information is received within the preset time, the current network state is good, and the first transmission protocol is continuously used for data transmission. And when the client determines that the corresponding information is not received within the preset time, the client indicates that the current network state is not in an active state, the client switches the transmission protocol and transmits data by using the switched transmission protocol. Namely, the client can switch the transmission protocol in real time according to the change of the network state, so that the normal transmission of data is ensured.
