Detailed Description
In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the embodiments described below are only a part of the embodiments of the present invention, and not all of the embodiments. 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.
The first embodiment is as follows:
as shown in fig. 1, which is a schematic flowchart of a streaming media transmission method provided in an embodiment of the present invention, the method may include:
and step S101, detecting whether a router connected with the streaming media robot is switched or not.
The streaming media robot is a robot that collects and transmits streaming media. In this embodiment, a first service set identifier of a router connected to the streaming media robot at a current detection time may be obtained first. The Service Set Identifier (SSID) is used to distinguish different networks, the router broadcasts the SSID, and the streaming media robot obtains the SSID by analyzing the broadcast information. Specifically, the information contained in the broadcast information is arranged in order: timestamp (8 bytes), Beacon interval (2 bytes), Capability Information (2 bytes), SSID (9 bytes) … …, wherein the contents of the 9 bytes from 13 th to 21 th are intercepted as the SSID of the router.
And then, comparing the first service set identifier with a second service set identifier to obtain a comparison result, wherein the second server identifier is a pre-stored service set identifier of a router connected with the streaming media robot before the current detection moment.
If the comparison result is consistent, it is determined that the router connected to the streaming media robot is not switched, and at this time, step S102 is performed, and if the comparison result is inconsistent, it is determined that the router connected to the streaming media robot is switched, and at this time, step S103 and subsequent steps are performed.
And step S102, keeping the original transmission connection.
Under the condition that the router is not switched, the original transmission connection is still effective, and the streaming media robot and the streaming media target terminal can still transmit the streaming media through the original transmission connection.
And step S103, acquiring the public network IP address of the streaming media robot after the router is switched.
In the local area network provided by the new router, the new router sets a public network IP address and a public network port, a local area network IP address and a local area network port and a mapping relation between the public network IP address and the public network port and the local area network port for the streaming media robot.
And step S104, judging whether the streaming media robot and the streaming media target terminal are in the same local area network.
In this embodiment, whether the public network IP address of the streaming robot and the preset public network IP address of the streaming target terminal are in the same lan or not is determined according to the public network IP address of the streaming robot and the preset public network IP address of the streaming target terminal, if the public network IP addresses of the streaming robot and the preset public network IP address of the streaming target terminal belong to the same network segment, it is determined that the streaming robot and the streaming target terminal are in the same lan, at this time, step S105 is executed, if the public network IP addresses of the streaming robot and the streaming target terminal do not belong to the same network segment, it is determined that the streaming robot and the streaming target terminal are not in the same lan, it is determined that the streaming target terminal and the streaming target terminal are not in the same lan, and at this time, step S106 is executed.
And step S105, establishing transmission connection between the streaming media robot and the streaming media target terminal in a local area network.
Specifically, a local area network IP address and a local area network port of the streaming media robot after router switching are first acquired, and then the local area network IP address and the local area network port of the streaming media robot are sent to the streaming media target terminal, so that the streaming media target terminal establishes transmission connection with the streaming media robot through the local area network IP address and the local area network port of the streaming media robot.
And S106, establishing transmission connection between the streaming media robot and the streaming media target terminal through NAT penetration.
With the increasing number of internet users, the internet protocol version four (IPv4) address resource used by the internet is very tight, and it is not enough to make every user have an IPv4 address, i.e. a public network IP address, which can directly access the internet. In order to enable users in enterprises to use internet resources, enterprises generally adopt a Network Address Translation (NAT) technology to convert the local area Network IP Address in the enterprise into a public Network IP Address capable of directly accessing the internet, so that one or more users in the enterprises can use one public Network IP Address to access the internet.
Although the use of the NAT technology can temporarily alleviate the crisis of IPv4 address resources, the NAT technology can affect the internet interoperability since it can limit the access of internet users to users inside the enterprise behind the NAT device. In order to enable users located in the internet to access users located inside the enterprise behind the NAT device, NAT traversal technology needs to be used to traverse the NAT device.
In this embodiment, NAT traversal may be specifically performed through the following steps: firstly, the streaming media robot establishes communication connection with a preset streaming media server, then obtains a public network port of the streaming media robot after router switching, and sends NAT penetration instruction to the streaming media server, the NAT penetration instruction includes the public network IP address and the public network port of the streaming media robot, and the public network IP address and the public network port of the streaming media target terminal, so that the streaming media server controls the streaming media target terminal to send an NAT penetration detection packet to the public network IP address and the public network port of the streaming media robot, thereby establishing a transmission connection from the streaming robot to the streaming target terminal, and finally, and the streaming media robot sends an NAT penetration detection packet to a preset public network IP address and a preset public network port of the streaming media target terminal, so that transmission connection from the streaming media target terminal to the streaming media robot is established.
To sum up, the embodiment of the present invention detects whether a router connected to a streaming media robot is switched, and if the router connected to the streaming media robot is switched, it indicates that the streaming media robot enters a new local area network during a moving process, and an original transmission connection is not already available, at this time, a public network IP address of the streaming media robot after the router is switched is obtained, and it is determined whether the streaming media robot and the streaming media target terminal are in the same local area network according to the public network IP address of the streaming media robot and a preset public network IP address of the streaming media target terminal, if the streaming media robot and the streaming media target terminal are not in the same local area network, a transmission connection between the streaming media robot and the streaming media target terminal is established through NAT, that is, a transmission connection between the streaming media robot and the streaming media target terminal is re-established in the switched local area network, continuous transmission of streaming media is guaranteed.
Example two:
as shown in fig. 2, which is a schematic flowchart of a streaming media transmission method provided in an embodiment of the present invention, the method may include:
step S201, whether a router connected with the streaming media robot is switched or not is detected.
If the router connected to the streaming media robot is not switched, step S202 is executed, and if the router connected to the streaming media robot is switched, step S203 and the following steps are executed.
Step S202, the original transmission connection is kept.
And step S203, acquiring the public network IP address of the streaming media robot after the router is switched.
And step S204, judging whether the streaming media robot and the streaming media target terminal are in the same local area network.
If both are in the same lan, step S205 is executed, and if both are not in the same lan, step S206 and the following steps are executed.
And step S205, establishing the transmission connection between the streaming media robot and the streaming media target terminal in the local area network.
The process from step S201 to step S205 is similar to the process from step S101 to step S105 in the first embodiment, and specific reference may be made to the detailed description in the first embodiment, which is not repeated herein.
And step S206, sending a UPNP function inquiry command to the switched router.
Universal Plug and Play (UPNP) is an architecture for common peer-to-peer network connections for computers and smart devices. UPNP is based on Internet standards and technologies that allow such devices to automatically connect and interoperate with each other.
When accessing the switched router, the streaming media robot does not know whether the router has the UPNP function, and therefore, a UPNP function query instruction needs to be sent to the switched router.
And step S207, receiving the feedback information sent by the switched router.
After receiving the UPNP function query instruction sent by the streaming media robot, the router after switching sends feedback information to the streaming media robot, and the streaming media robot can know whether the router after switching has the UPNP function or not by reading the feedback information.
And step S208, judging whether the switched router has a UPNP function.
If the switched router has the UPNP function, step S209 is executed, and if the switched router does not have the UPNP function, step S210 is executed.
Step S209, establishing UPNP mapping between the streaming media robot and a preset streaming media server according to a UPNP protocol so as to establish transmission connection between the streaming media robot and the streaming media target terminal through the streaming media server.
Firstly, performing UPNP mapping on a local area network IP address and a local area network port of the streaming media robot, namely establishing a mapping relation between the local area network IP address and the local area network port of the streaming media robot and a public network IP address and a public network port of the streaming media server, and performing UPNP mapping on the local area network IP address and the local area network port of the streaming media robot so that a transmission request sent by a streaming media target terminal can be forwarded to the streaming media robot by the streaming media server after reaching the streaming media server. For example, if the local area network IP address of the streaming media robot is IP 1: 192.168.0.1, PORT number of local area network PORT is PORT 1: 7766, the public network IP address of the streaming server connected to said streaming robot is IP 2: 222.222.222.222, PORT number of public network PORT is PORT 2: 3344 and the port mapped public IP address and public port are mapped to 222.222.222.222 and 3344, respectively.
Then, the streaming media robot binds the public network IP address obtained by the port mapping, the public network port and the identification of the streaming media robot and reports the binding to the streaming media server. In the embodiment of the present invention, the identifier of the streaming media robot may specifically be the device ID of the intelligent device, and certainly, may also be other identifiers capable of uniquely indicating the streaming media robot, which is not specifically limited herein. After the port mapping is carried out, the streaming media robot binds the public network IP address, the public network port and the identification of the streaming media robot obtained after the mapping and reports the public network IP address, the public network port and the identification of the streaming media robot to the streaming media server. For example, if the local area network IP address of the streaming media robot is IP 1: 192.168.0.1, PORT number of the local area network PORT is PORT 1: 7766, the public network IP address obtained by said mapping is IP 2: 222.222.222.222, PORT number of public network PORT is PORT 2: 3344. if the identifier of the streaming media robot is S1, the streaming media robot binds the public network IP address 222.222.222.222, the public network port 3344 and the identifier of the streaming media robot S1, and reports the binding to the streaming media server.
When the streaming media server receives a transmission request of the streaming media target terminal to the streaming media robot, the streaming media server acquires a corresponding public network IP address and a public network port according to the identification of the streaming media robot carried in the transmission request, and forwards the received transmission request to the streaming media robot according to a port mapping relation. The streaming media robot monitors a local area network port, can timely know whether a transmission request is received or not, and responds to the received transmission request when receiving the transmission request, so that the streaming media robot and the streaming media target terminal establish transmission connection through the streaming media server.
And step S210, establishing transmission connection between the streaming media robot and the streaming media target terminal through NAT penetration.
The process of step S210 is similar to the process of step S106 in the first embodiment, and specific reference may be made to the detailed description in the first embodiment, which is not repeated herein.
If the NAT traversal fails, the transmission connection between the streaming media robot and the streaming media target terminal can only be transferred through the streaming media server, specifically, the streaming media robot first sends streaming media to the streaming media server, and then the streaming media target terminal receives the streaming media from the streaming media server.
In summary, in the embodiment of the present invention, on the basis of the first embodiment, the streaming media robot and the streaming media target terminal may perform transmission connection under various conditions, that is, if the streaming media robot and the streaming media target terminal are in the same local area network, direct transmission in the local area network is performed; if the two different networks are different but the router has the UPNP function, the transmission is carried out according to the port mapping established by the UPNP protocol; if the two networks are different and the router does not have the UPNP function, the transmission connection is established through NAT penetration; if NAT fails to penetrate, then transit transmission is carried out through the streaming media server. And the transmission connection between the streaming media robot and the streaming media target terminal can be reestablished in the switched local area network under various conditions, so that the continuous transmission of the streaming media is ensured.
