To understand "distributed", we must first mention "centralized". In AV engineering construction, many people are Xi to use centralized audio and video matrix, conference system, multi-function hall, smart center, splicing processor, recording system, central control system and other functional areas such as conference rooms, and each functional area is relatively independent in all corners of the building. There are a series of problems in traditional AV construction: the coexistence of multimedia information, the difficulty of cooperation between multi-producer equipment, the difficulty of converting multiple video formats, the difficulty of long-distance transmission, the low efficiency of design and construction, and the difficulty of use and maintenance.

GEFFEN Distributed Agent Collaboration can effectively solve the above crux of the problem. It solves the problem of information (data) security in the command center and the isolation of the work of each seat, greatly simplifies the customer's business process, and improves the customer's business efficiency.

GEFFEN Technology Dual-Engine Distributed Agent Management System
GEFFEN Technology's twin-engine distributed management system is a system in which hardware or software components are distributed on different network computers and communicate and coordinate with each other only through messaging. Adopting all-IP architecture and distributed technology as the core, by setting up KVM agent input nodes, KVM agent output nodes, network switches, user hosts, monitors, and a set of mice and keyboards, agents can call data from different operating systems, different resolutions, and different interfaces at will, without worrying about switching. Provide overall solutions for mission-critical environments to achieve centralized management, efficient coordination, real-time control, information communication, and security control. Realize the intelligent agent management of "man-machine separation" and "one person with multiple machines" in the command system.

First: product technology maturity

It has only been a few years since the GEFFEN distributed seating system was officially launched. Therefore, only after a long period of early research and development and technology accumulation, the product will become more and more mature. Its high technical threshold lies in its algorithm and coding technology, which discourages many manufacturers. For example, the codec compression and decoding technology of distributed agent system on video transmission has gone through three stages:
In the first stage, due to the limitations of the encoding technology, the video transmission adopts a completely uncompressed way to transmit the original stream. This method requires a lot of bandwidth, and a single-channel 1080P@60-frame video requires up to about 3G bandwidth.
In the second stage, as the application requirements change, the uncompressed bitrate stream mode can no longer meet the needs of a large number of video transmissions. Therefore, on the basis of traditional compression (such as MPEG2, MPEG4, etc.), the hybrid stream compression method with its own algorithm was born. At this time, a single 1080P@60-frame video is compressed and transmitted, requiring only a few hundred megabytes of bandwidth. There is no doubt that it basically solves a certain need for system expansion in a certain period of time.
In the third stage, with the birth of big data and the needs of social development, the demand for small bandwidth for massive signal access is becoming more and more urgent. The H.265 international standard compression coding algorithm is a compression algorithm that solves the problem of small bandwidth. It not only achieves small bandwidth (as low as tens of megabits or even several megabits) to support massive signal expansion of the system, but also ensures the high-definition restoration of the original image quality. The chip comes as standard.
Second: the stability of the system, there is no doubt that the stability of the system is one of the core elements to judge the product quality of the distributed agent system. Stability is judged by a wide range of criteria, but usually includes three aspects:
1. Synchronization, GEFFEN Geffen large screen splicing distributed seat system is mainly to process the access signal and realize the display on the screen, so the synchronization requirements for the signal on the screen are extremely strict, it is mainly reflected in the video can not produce any jam, otherwise it may lead to tearing of the image on the screen, which seriously affects the use effect.
2. Real-time, the core application of GEFFEN distributed agent system is to process the real-time transmission of video signals, and to be able to display them on the screen in real time, so as to provide a timely, fast and effective command decision-making basis. This provides extremely important conditions for timely deployment and decision-making in major accidents to recover losses. Just as in the event of a major disaster such as an earthquake, fire, or landslide, the user can grasp the disaster situation and deploy disaster relief at the scene in real time at the first moment of the disaster, so it can be said that time is the safety of life and property.
3. Decentralization, for the distributed agent system, if the entire system cannot run due to the failure of some modules, it will mean a catastrophe for users. A truly distributed system uses distributed spliced nodes to process only its own signals, and has no impact on other nodes in the system. When a single node fails, the system remains in a normal state without any impact. Only the damaged node needs to be replaced, and the access signal can be arbitrarily scheduled and processed immediately.
Third: system compatibility
GEFFEN distributed agent system often requires a variety of devices, so a good distributed agent system must have the principle of openness. It should not only support the access of almost all types of signals, but also support the docking of other business platforms, otherwise it is easy to cause the system to crash due to compatibility problems and cannot reflect the superiority of the distributed agent system compared with the traditional distributed agent system. For example, in a distributed agent system, there are even thousands of access devices. However, in many current systems, due to the expansion of signal access and the update of equipment in different periods, the brand is also ever-changing. The private protocol of each manufacturer leads to incompatibility with each other and affects the stability of the entire system.
Another example is the requirement to access some external platforms because of system upgrades, which require the distributed agent system to have an excellent compatibility, otherwise it is difficult to maintain the overall stable operation of the system. Therefore, when choosing a distributed agent system, customers should first understand whether it has good openness, whether it can be connected to different platforms, compatible with different devices, etc. These are the criteria for measurement.
Fourth: the ease of use of the system
The ease of use of GEFFEN systems usually includes the ease of use of the user at the end of the operation. But with the advancement of technology and the increase in demand, simplicity is no longer the only criterion for ease of use. Visual operation, what you see is what you get, has become an important standard for users to have a good operation experience. In the Internet+ era, the use of Internet technology to realize the synchronization of the operating client and the display terminal for visual linkage control and real-time preview and echo of the access signal should be the standard configuration of the advanced distributed agent system.
Fifth: the scalability of the system
The scalability of a highly platformized distributed agent system is very necessary. Because in practical applications, it is usually ignored that with the expansion of business scale and changes in various applications, the system needs to be continuously expanded to meet new needs. It often happens that due to poor consideration of the preliminary engineering, the existing system cannot meet the new requirements, so that the original system needs to be abandoned and rebuilt. This waste of human and financial resources is unacceptable to users.
The GEFFEN distributed agent system is unlimited in terms of scalability, and it does not only allow how many signals to access and how many outputs are allowed. When the system size needs to be increased, only a small number of nodes need to be added to complete the expansion. There is no need to scrap the original system equipment, and there is no complicated construction process, everything is simple and easy.
Sixth: the security of the system
In the era of big data, the security and confidentiality of information has become the consensus of the whole society. In particular, it is a distributed agent system for enterprises, governments, military and other functional departments. Therefore, when selecting the distributed agent system, it is necessary to ensure that its products have the qualifications of self-developed core technology and underlying confidentiality technology, which fundamentally guarantees the core interests of users.

The distributed agent management system platform adopts an all-IP architecture, with distributed technology as the core, and by setting up agent input nodes, agent output nodes, network switches, user hosts, displays, and a set of mice and keyboards, agents can call data from different operating systems, different resolutions, and different interfaces at will, without worrying about switching. Provide overall solutions for mission-critical environments to achieve centralized management, efficient coordination, real-time control, information communication, and security control. Realize the intelligent agent management of "man-machine separation" and "one person with multiple machines" in the command system.
