Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
Fig. 1 is a flowchart of interaction steps of a port multiplexing method according to an embodiment of the present invention, where the method is applied to a port multiplexing system, and the system includes: the system comprises a server and a terminal, wherein a first physical port of the terminal and a second physical port of the server are used for bearing at least one physical data link based on a user datagram protocol, and a plurality of virtual data links are deployed on at least one physical data link.
The method comprises the following steps:
step 101, the terminal selects a target virtual data link for the current data transmission.
It should be noted that, the server in the embodiment of the present invention refers to an electronic device that provides service data for an application client in a terminal. The terminal refers to an electronic device having functions of data storage, data processing, data transmission, and the like, for example: personal computers, cell phones, tablet computers, etc., in which an application client can be installed, which can interact data with a server of an application. The user datagram (User Datagram Protocol, UDP) protocol is a connectionless transport layer protocol that is widely used for the transport of streaming media data. In practical applications, the client side of the streaming media application program may be installed on the terminal, and the streaming media application program has the requirements of low delay and high transmission efficiency, so that the UDP protocol is mostly adopted to perform data interaction with the server.
The first physical port and the second physical port are physical ports in the terminal and the server, respectively, for transmitting UDP packets. The physical data link between the first physical port of the terminal and the second physical port of the server is used for realizing communication connection between the terminal and the server. The virtual data link is a data transmission channel pre-deployed on a physical data link between the terminal and the server based on a UDP protocol, and typically, the terminal and the server interact through a signaling link to negotiate to deploy the virtual data link before data transmission.
In the embodiment of the invention, the terminal can automatically determine the response data which needs to be acquired by carrying out data transmission with the server according to the selection of the user or the system setting, so that the virtual data link deployed for the response data is used as the target virtual data link for carrying out data transmission at this time.
Step 102, the terminal determines a first virtual port number for identifying the first physical port according to the port correspondence of the target virtual data link.
In the embodiment of the present invention, the first virtual port number is an index for identifying a first physical port of the terminal, and similarly, the second virtual port number in the subsequent step is an index for identifying a second physical port of the server. The port corresponding relation comprises a corresponding relation of a first virtual port number and a second virtual port number, wherein the port corresponding relation is built and stored in advance through negotiation when a terminal and a server deploy virtual data links on physical data links, and different virtual data links correspond to different port corresponding relations. It can be understood that, since the common physical ports are all provided with unique physical port numbers, if multiple virtual data links are deployed on the same physical port, different virtual data links cannot be distinguished through the physical port numbers, so that the embodiment of the invention deploys corresponding virtual ports for each virtual data link on the physical port and uses the virtual port numbers to identify the virtual ports, thereby not only identifying the virtual data link according to the virtual port numbers, but also determining the physical port corresponding to the identified virtual port according to the virtual port numbers.
Step 103, the terminal sends a data request carrying the first virtual port number to a second physical port of the server through the first physical port, and the second physical port is further identified by a second virtual port number in the port corresponding relationship.
In the embodiment of the invention, the terminal equipment takes the first physical port identified by the first virtual port number as a source port, takes the second physical port identified by the second virtual port number as a destination port, encapsulates the data request carrying the first virtual port number according to the UDP protocol and then sends the encapsulated data request to the server. It can be understood that, because the terminal stores the port corresponding relationship when negotiating in advance to establish the virtual data link, when data transmission is required through the existing virtual data link, the first physical port required for sending the data request can be determined according to the first virtual port number in the port corresponding relationship, and it is not necessary to reallocate an idle UDP port for the data request. It can be understood that, in the prior art, since an idle UDP port is allocated for each data transmission based on the UDP protocol, the same UDP port can only be used for data transmission of one data, and in this scheme, multiple virtual ports are deployed on the UDP port and identified by using the virtual port numbers, so that when a terminal sends different data requests through multiple virtual data links, the same pair of first physical port and second physical port can be determined according to different first virtual port numbers and second virtual port numbers of the multiple virtual data links, so that the UDP port can be used for data transmission of multiple virtual data links at the same time.
Step 104, when the server receives the data request, determining a second virtual port number corresponding to the first virtual port number according to the port correspondence.
In the embodiment of the invention, the server extracts the first virtual port number carried by the data request sent by the terminal after decapsulating the data request based on the UDP protocol, and because the server stores the port corresponding relation of the target virtual data link when negotiating and deploying the target virtual data link in advance with the terminal, the server can determine the second virtual port number corresponding to the first virtual port number according to the port corresponding relation.
Step 105, the server generates response data according to the data request.
In the embodiment of the invention, the server determines the data required by the terminal according to the data identifier extracted from the data request, and then encapsulates the data and the second virtual port number based on the UDP protocol to obtain response data.
And step 106, the server sends response data carrying the second virtual port number to the first physical port through the second physical port.
In the embodiment of the invention, the server takes the second physical port identified by the second virtual port number as a source port and takes the first physical port identified by the first virtual port number as a destination port, so as to send response data carrying the second virtual port number to the terminal. It can be understood that, because the server stores the port corresponding relationship when the server negotiates and deploys the target virtual data link in advance, after receiving the data request carrying the first virtual port number, the server can send the response data along the second physical port identified by the second virtual port number in the port corresponding relationship, and there is no need to repeatedly allocate the physical port for sending the response data by adopting the UDP protocol in the data transmission process of the virtual data link, that is, when the server and the terminal use the virtual data link to perform data transmission, only the physical ports at two ends need to be allocated once by adopting the UDP protocol when deploying the virtual data link, so that the same physical port can be allocated to other virtual data links by the UDP protocol in the idle period after having been allocated to one virtual data link, and different virtual data links can be distinguished according to the virtual port numbers, so that the same physical port can be used for data transmission of multiple virtual data links at the same time.
Specifically, referring to fig. 2, a schematic diagram of a data transmission principle of a port multiplexing method of the present invention is shown, where a terminal includes a client a and a client B, a data link a11 and a data link a12 are a first data link of the client a, IPA2 is a first IP address of the client a, and vport a31 and vport a32 are first virtual port numbers of the client a; data link B11 and data link B12 are the first data link of client B. IPB2 is the first IP address of client B, vport B31 and vport B32 are the first virtual port numbers of client B. The server comprises a sub-server C and a sub-server D, wherein the sub-server C and the sub-server D are virtual servers deployed in the server. Data link C11 and data link C12 are the second data link of child server C, IPC2 is the second IP address of child server C, vport C31 and vport C32 are the second virtual port number of child server C; data link D11 and data link D12 are the second data link of sub-server D, IPD2 is the second IP address of sub-server D, vport D31 and vport D32 are the second virtual port number of sub-server D. There is a physical data link between the first physical port and the second physical port, the physical data link having disposed thereon a plurality of virtual data links between the terminal and the server. The first data link and the second data link are memory addresses of data in the device.
In particular, each virtual data link deployed on the physical data link is used for data transmission between the first data link and the second data link. As shown in fig. 2, there is a virtual data link between the data link a11 and the data link C11, between the data link a12 and the data link C12, between the data link B11 and the data link D11, and between the data link B12 and the data link D12. The terminal and the server store the corresponding port corresponding relation of each virtual data link, and the corresponding relation of the ports comprises the corresponding relation of the first virtual port and the second virtual port number. For example: the virtual data link between the data link a11 and the data link C11 stores the correspondence between the first virtual port number vport a3 and the second virtual port number vport C31 at the terminal and the server, and these virtual port numbers are used to identify the physical ports, for example: the vport a31, vport a32, vport b31, vport b32 of the terminal identify the first physical port of the terminal and the server is the same. Therefore, in the data transmission process, the terminal and the server identify the physical port through the virtual port number corresponding to the virtual data link, so that the physical data link on the same physical port can deploy a plurality of virtual data links and distinguish the virtual data link to which the transmission data belongs according to the port corresponding relation between the first virtual port number and the second virtual port number. Further, since the IP addresses of different clients in the terminal and different sub-servers in the server are different, a mapping table between the virtual port number and the IP address can be also established, so as to distinguish the virtual data links of different clients in the same terminal. Further, the mapping tables between the data link, the IP address and the virtual port number are stored in the terminal and the server, for example: data link a11 in fig. 2: IPA2: vport a31.
By way of example, the data transmission procedure of a virtual data link will be described below by taking as an example a virtual data link between the data link a11 of the client and the data link C11 of the sub-server C, and the virtual data link between the other data links can refer to this part of the content:
s1, a client A in a terminal determines a local data link A11 which needs to be subjected to data transmission, so that a virtual data link between the data link A11 and a data link C11 of a server is used as a target virtual data link of the data transmission;
s2, the client A acquires a data request carrying a first virtual port number A31 according to the data link A11, and queries a first IP address IPA2 of the client A according to a mapping table to package the data request according to a UDP protocol;
s3, the client A sends the packaged data request from a first physical port of the terminal to a second physical port of the server;
s4, the server extracts a first virtual port number A31 in the data request based on the UDP protocol, and determines a local second virtual port number C31 according to the port corresponding relation, so that the data request is sent to a sub-server C where the second virtual port number C31 is located;
S5, the sub-server C queries a data link C11 corresponding to the second virtual port number C31 according to the mapping table to acquire response data carrying the second virtual port number C31, and then queries a second IP address IPC2 of the sub-server C according to the mapping table to package the response data according to a UDP protocol;
s6, the sub-server C sends the packaged response data to a first physical port of the terminal through a local second physical port;
and S7, the terminal extracts a second virtual port number C31 through the unpacking response data, and determines a local first virtual port number A31 according to the port corresponding relation, so that the response data is sent to a client A where the first virtual port number A31 is located.
According to the port multiplexing method provided by the embodiment of the invention, the physical ports of the physical data links are identified by deploying the virtual data links on the physical data links based on the UDP protocol and utilizing the virtual port numbers of the virtual data links, so that when the terminal and the server perform data transmission through the virtual data links, the physical ports of the physical data links can be determined according to the port corresponding relation between the virtual port numbers at two ends and used for data transmission of the virtual data links, the physical ports of the physical data links can be deployed through the virtual port numbers through the virtual data links, and data transmission is performed through the virtual data links, thereby realizing multiplexing of the UDP ports and improving the data transmission capacity of the UDP ports.
Fig. 3 is a flowchart of steps of another port multiplexing method according to an embodiment of the present invention, which is applied to a server in a port multiplexing system, where the system further includes: the terminal is used for bearing at least one physical data link based on a user datagram protocol between a first physical port of the terminal and a second physical port of the server, and a plurality of virtual data links are deployed on at least one physical data link; the method comprises the following steps:
step 201, when a data request carrying a first virtual port number sent by the terminal is received, determining a second virtual port number corresponding to the first virtual port number according to the port correspondence, where the first physical port is identified by the first virtual port number in the port correspondence, and the second physical port is identified by the second virtual port number.
This step is described in detail with reference to step 104, and will not be described in detail here.
And 202, generating response data according to the data request.
This step may be described in detail with reference to step 105, and will not be described here again.
And step 203, sending response data carrying the second virtual port number to the first physical port through the second physical port.
This step is described in detail with reference to step 106 and will not be described here.
Optionally, referring to fig. 4, before the step 201, the method further includes:
and step 204, receiving a virtual link construction request sent by the terminal, wherein the virtual link construction request comprises a first virtual port number.
In an embodiment of the invention, the virtual link construction request is sent by the terminal to the server in a signalling format based on TCP (Transmission Control Protocol ). When the terminal needs to construct a virtual data link with the server, the first virtual port number of the terminal can be added into a virtual link construction request and sent to the server.
Step 205, generating a second virtual port number of the server according to the first virtual port number.
In the embodiment of the invention, the server allocates any local UDP port in an idle state for the first physical port identified by the first virtual port number as a second physical port, deploys the virtual port on the second physical port, and generates a second virtual port number for identifying the virtual port.
And 206, establishing the corresponding relation between the first virtual port and the second virtual port number as the port corresponding relation of the virtual data link deployed based on the physical data link.
In the embodiment of the invention, the server establishes the corresponding relation between the first virtual port and the second virtual port, and takes the corresponding relation as the port corresponding relation of the deployed virtual data link to be stored locally for subsequent inquiry.
And step 207, sending a virtual link construction response to the terminal, wherein the virtual link construction response comprises the second virtual port number.
In the embodiment of the invention, after the port corresponding relation of the deployed virtual data link is locally stored, the server also needs to send a virtual link construction response carrying the second virtual port number to the terminal, so that the terminal can also know the deployment condition of the virtual data link. The second virtual port number generated by the server is only carried in the virtual link construction response, and the port corresponding relation is not directly carried, so that the data volume of the virtual link construction response can be reduced, and the data transmission resources are saved.
According to the embodiment of the invention, the port corresponding relation is determined through interaction between the terminal and the server, the physical port bearing the virtual data link is recorded in a mode that the virtual port number identifies the physical port, and the physical port in data transmission is recorded without any intermediate equipment, so that the streaming media application layer protocol of the intermediate equipment is not supported in the data transmission process, such as SIP (Session Initiation Protocol ), RTSP (Real Time Streaming Protocol, real-time streaming protocol), webRTC (Web Real Time Communication, web instant messaging) and the like, can be compatible. It can be understood that, because some streaming media application layer protocols are provided with proxy server mechanisms, the proxy server is suitable for distributing the message, that is, directly sending the message to the opposite terminal device, while the intermediate device is not an actual opposite terminal device, the scheme of the invention can be exactly suitable for the streaming media application layer protocols, and the applicability of UDP port multiplexing is improved.
Optionally, the virtual link construction request further includes: identification of the first data link of the server, with reference to fig. 4, the step 205 includes:
sub-step 2051, determining at least one candidate data link corresponding to the first data link according to a preset link correspondence and an identification of the first data link.
In the embodiment of the invention, the identifier of the first data link is an index of the first data link, and the first data link is a storage address of the data request sent by the terminal. The preset link corresponding relation is pre-generated by the server and is sent to the terminal. For example: the developer can preset a preset link corresponding relation, and then add the first data link into an installation package of the application program client, so that when the client of the terminal requests the server to acquire data according to the first data link, the server can determine the corresponding candidate data link according to the preset link corresponding relation, wherein the candidate data link is a storage address of data provided by the server.
