Embodiment 1

[0052] A control method for an underwater acoustic communication network, comprising the following steps:

[0053] Step 1, the multiplexing layer of the master control node creates a socket, realizes the information transmission between the multiplexing layer of the master control node and the PC in the communication network, and realizes the multiplexing layer of the master control node and Information transmission between application layers; simultaneously analyze and process the information passed from PC to application layer; then control information is transferred from application layer, network layer, data link layer and physical layer in the control link to the communication network forwarding node and destination node;

[0054] Step 2. In the underwater acoustic communication network, for the forwarding node, the physical layer of the forwarding node receives the master control node information, and transmits the control information to the multiplexing layer through th...

Embodiment 2

[0056] Embodiment 2: Combination figure 1 To describe this embodiment,

[0057] The specific implementation process of step 1 of this embodiment is as follows:

[0058] Step 1.1, aiming at the master control node in the communication network, the multiplexing layer of the master control node creates a socket as a way for the multiplexing layer to communicate with the PC, so as to realize the information transmission between the multiplexing layer and the PC; the socket sockfd is created The file descriptor returned after the socket is successful, the socket is operated through the socket sockfd; in this way, the socket can be operated like a file;

[0059] After the socket sockfd is successfully created, use the communication method of the socket to realize the communication with the PC; both the PC and the multiplexing layer can realize the communication between the two by reading and writing the socket Communication;

[0060] Step 1.2. The PC writes information to the soc...

Embodiment 3

[0068] Example Three: Combining figure 2 To describe this embodiment,

[0069] Step 2.1, the multiplexing layer of the forwarding node creates WFIFO pipelines, RFIFO pipelines and FIFO pipelines for realizing communication between the multiplexing layer and the application layer; the application layer realizes multiplexing by reading and writing WFIFO pipelines, RFIFO pipelines and FIFO pipelines Communication between the user layer and the application layer;

[0070] Step 2.2, when the multiplexing layer reads the information transmitted from the application layer in the control link in the FIFO pipeline, the time and control command of the timing start data link in the information are passed to the function of processing the control command, and the processing control The function of the command will perform the corresponding operation according to the time of starting the data link and the control command, that is, perform the operation of step 2.3, step 2.4, step 2.5 or ...

Abstract

The invention relates to the underwater acoustic communication network technology field and more particularly, to an underwater acoustic communication network control method. The method comprises the following steps: creating a socket on the multiplex layer of a master control node; in the underwater acoustic communication network, receiving the information of the master control node by the physical layer of a forwarding node; in the underwater acoustic communication network, receiving the information of the forwarding node by the physical layer of a target node; transmitting the control information through a data link layer, a network layer, and an application layer to a multiplex layer; creating by the multiplex layer an RFIFO pipeline and a WFIFO pipeline as well as an FIFO pipeline to realize the data transmission between the multiplex layer and the application layer; and analyzing the received information and carrying out corresponding treatment. According to the invention, through the utilization of the multiplex layer technology to control and configure a master node and through the use of the master node, the other nodes of the underwater acoustic communication network are controlled and configured indirectly so that the control and configuration of every communication node could be avoided.

Description
