• Add on: the development of hiding technology and the expansion of digital applications need to find a compromise between concealment and the ability to pass through the hidden channels Data transmission. This article provides a justification for the study of the collective data channel transmission capability in the video stream of the redistribution system. Satellite communication is a method that can add a hidden data channel in video stream through asynchronous multiplexing.
• Keywords: digital dictation, covert channel, covert channel, covert channel transmission capability, asynchronous multiplexing, variable channel transmission capability
• Note: although it is possible to use programs and programmable networks that ensure proper and secure management of these networks, Continuous improvement. The principles of these protocols show the communication handlers in the network device, the control level of the network device is centralized on the designated controller, and The transfer process from one device to another. This paper introduces a principle research of software configuration network management protocol - openflow. This paper discusses in detail the mechanism of transferring network traffic to openflow switch and the program of the switch itself to process the received information.
• Keywords: programmable network, openflow switch, openflow port, pipeline, flow meter, grader, executive action
• Additional note: This paper introduces the digital video sequence analysis method based on linear conflict phenomenon in detail. It describes the condition of statistical unknowability, which is the basis for the development of a stable linear digital stack collision. The test results (in tabular form) show that in the process of removing the stack, it is written in C + + language (+ attacker) +. The research uses different formats and video sequence types, which are characterized by frames per second and scene change speed, The degree of interrelationship between staff, bit rate, etc D.
• Keywords: stack analysis, digital video sequence, digital stack, linear conflict phenomenon, invisible statistics, time-dependent, Type 1-2 conflict, frame decomposition, linear addition, container, bit rate, redundancy and noise level, compression, filter

• Additional note: This paper studies the method of calculating the attenuation coefficient of bending part of weak guide optical fiber by using stepped circular cross section 3. The refractive index is based on the calculation of the stress distribution of the electric and magnetic fields of the directional wave type. The results of calculating the attenuation coefficient of bending radius of different fibers are provided. The results were compared with the experimental data.
• Key words: optical fiber, mode, single-mode fiber, bending loss, attenuation coefficient
• Note: the excitation method and modulation method of high frequency controllable resonant current inverter are studied. The time chart of the self-excited load of the inverter is given here. The work of the inverter when using the PSPICE type Gan transistor is studied. Considering the actual characteristics, the linear modulation technology is also studied. The modulation characteristics are maintained. The received inverter efficiency is more than 90%.

• Explanation: at present, optical transmission technology is regarded as a possible way to deal with the imminent challenge of radio spectrum crisis. This technology combines energy efficiency with security and high transmission rates. This paper discusses the possibility of building a wireless data transmission system based on the visible diode, and calculates its throughput.

• Note: This paper focuses on the organization and scheduling of adaptive multiplexing of the earth station equipment channel multi-functional network 4. Satellite communication should deal with the changing interference environment. The multi service network traffic adaptive multiplexing mode is developed to adapt to the service priorities and the instability of the received information flow based on the network. This is a Markov modulated Poisson process. The calculation method based on the proposed model is used, and the model has been implemented Programming in Matlab environment.

• Note: This article is about the development of information security theory and information war. The purpose of this study is to determine how to translate the most relevant it impacts into operators, This is a system based on the transformation of the trade structure into a more complex one. The scientific method of using the complexity of communication structure to prove the influence of information technology is based on the function conversion method. I used to be in Rio Linz and his science school representative. The resulting new it impact could be used to test the sustainability and security of telecommunications systems in the future, And to develop ways to protect them.
