Description
Technical field
The application relates to a kind of method and system realizing teaching communication based on udp protocol.
Background technology
In modern teaching, computer becomes indispensable educational aid gradually.Especially the greatly developing of wireless network in recent years, making to utilize mobile terminal to carry out teaching by local area network (LAN) becomes more welcome new model.The existing network transmission protocol has two kinds of forms, connection-oriented service (TCP) and connectionless service (UDP).TCP(Transmission ControlProtocol, transmission control protocol) be a kind of connection-oriented, reliable, based on the transport layer communication protocol of byte stream.UDP (User Datagram Protocol, User Datagram Protoco (UDP)) is a kind of towards affairs, connectionless simple information transmission service.
Existing based in the teaching pattern of local area network (LAN), mostly all use Transmission Control Protocol to communicate.But in field research, a teacher is in the face of dozens of even up to a hundred students often, therefore, when teacher communicates with student, the communication based on Transmission Control Protocol needs to set up tens of even up to a hundred between the terminals and connects, and this greatly reduces the efficiency of transmission of network.
Summary of the invention
This application provides a kind of method and system realizing teaching communication based on udp protocol at least partly can improving above-mentioned defect of the prior art.
According to the one side of the application, provide a kind of method realizing teaching communication based on udp protocol, the method comprises: arrange first terminal and multiple second terminal, to make first terminal identical with the UDP receiving port of first terminal with multiple second terminal respectively with the UDP transmit port of multiple second terminal; First terminal and multiple second terminal start UDP monitoring service respectively; First terminal sends UDP message by its UDP transmit port to multiple second terminal; And multiple second terminal receives UDP message based on its UDP receiving port identical with the UDP transmit port of first terminal separately, thus operate according to UDP message, wherein, the UDP message that first terminal sends comprises the data for imparting knowledge to students or the instruction for interaction.
According to the another aspect of the application, provide a kind of system realizing teaching communication based on udp protocol, this system comprises first terminal and multiple second terminal.Wherein, it is identical with the UDP receiving port of first terminal with multiple second terminal respectively with the UDP transmit port of multiple second terminal that first terminal and multiple second terminal are configured to first terminal, and first terminal and multiple second terminal start UDP monitoring service respectively.In addition, first terminal is also configured to send UDP message by its UDP transmit port to multiple second terminal, multiple second terminal is configured to receive UDP message based on its UDP receiving port identical with the UDP transmit port of first terminal separately, thus operates according to UDP message.Wherein, the UDP message that first terminal sends comprises the data for imparting knowledge to students or the instruction for interaction.
As mentioned above, by the method and system realizing teaching communication based on udp protocol that the application provides, in teaching process, when the needs that are a teacher communicate with student, teacher's end only needs to send once, all student side can receive the information that teacher sends, and significantly improve the efficiency of transmission of network, decrease the pressure of teacher's end.
Accompanying drawing explanation
Fig. 1 is the schematic diagram realizing the system of teaching communication based on udp protocol according to the application's illustrative embodiments;
Fig. 2 is the schematic diagram realizing the process of teaching communication based on udp protocol according to the application's illustrative embodiments.
Embodiment
In order to understand the application better, make more detailed description with reference to the various aspects of accompanying drawing to the application.Be appreciated that the description of described drawings and detailed description just to the application's preferred embodiment, but not limit the scope of the application by any way.
Fig. 1 schematically illustrates the system 1000 realizing teaching communication based on udp protocol according to the application's execution mode.As shown in Figure 1, system 1000 comprises first terminal 100 and multiple second terminal 200-1,200-2 ... 200-n(is referred to as 200 hereinafter).
In one embodiment, first terminal 100 and the second terminal 200 can be the terminal can carried out wired or wireless mode and communicate, such as, and the electronic equipments such as computer, notebook computer, smart mobile phone, panel computer.The UDP transmit port of first terminal 100 can be configured to identical with the UDP receiving port of the second terminal 200, the UDP transmit port of the second terminal 200 can be configured to identical with the UDP receiving port of first terminal 100, and first terminal 100 and the second terminal 200 all can start UDP monitoring service.
First terminal 100 is configured to send UDP message to multiple second terminal 200 simultaneously, and the UDP message that multiple second terminal 200 is configured to based on receiving operates.Such as, in one embodiment, first terminal 100 can send the UDP message of quiet, page turning, hai roll, rolling etc. simultaneously to multiple second terminal 200, can arrange after the second all terminals 200 receives this UDP message according to this message to local device.In addition, first terminal 100 can send to multiple second terminal 200 the UDP message comprising concrete resources material simultaneously, and resources material can comprise audio data, video data, word message, station address etc.
For purposes of illustration, be respectively teacher's terminal referring to Fig. 2 for first terminal 100 and the second terminal 200 and with student terminal, the process communicated of imparting knowledge to students based on udp protocol realization be described, but the present invention is not limited to this.
As shown in Figure 2, in step s 201, teacher's terminal and student terminal are arranged to make the UDP transmit port of teacher's terminal identical with the UDP receiving port of student terminal, the UDP transmit port of student terminal is identical with the UDP receiving port of teacher's terminal.Then, teacher's terminal and student terminal start UDP monitoring service respectively.
In step S202, teacher's terminal sends the UDP message such as such as quiet, page turning, screen locking, hai roll to student terminal.
In step S203, after student terminal receives this UDP message, carry out operating to realize the interaction with teacher's terminal according to the type of this message.
