What is the architecture of the system network?
Systems Network Architecture is a proprietary network protocol owned and sold by International Business Machines (IBM) from 1974 to 2002. This controller is still common in thousands of different companies, especially financial companies such as banks and brokerage houses. Although the production of the IBM 3745/3746 communication controller has stopped, the system still receives updates from IBM and a wide range of third -party systems uses the controller as basic hardware.
The system architecture system protocol was to connect the main computers with other main images and communication terms. This process was mainly achieved by hard connections and telephone lines. When this technology came to the market in the middle of the 70s, the industry with the greatest need for fast and reliable interconnection of W Wjako banking. As a result, the architectsThe mains network has become a common method of exchange of information between financial systems. This first problem was the communication system itself. Terminals and mainframes of time used the communication ports of hard involvement to talk. These ports were buggy themselves, but when the feelings of different brands or models tried to communicate, the level of errors often made it impossible to connect. The system network architecture was a technological overlap that forced different ports to function in the same way to reduce the level of errors.
The second main disadvantage was built directly into IBM systems. At that time, the telephone network was so bad that the transmissions were extremely slow. In order to overcome this technological restriction, large computers used line Buchtudles to connect. Each of these volumes had hundreds of communication lines. Although the connection was slow, through different lines came so much information that it allowed a reasonable speedLasty transmission.
IBM systems had a hard limit of 256 peripheral connections to the processor. Although it was fine for most systems because they had a handful of printers and keyboards connected, each line connection was counted as its own peripheral. This has seriously limited the size of line bundles available to computers. Systemic network architecture has enabled the system to read a group of lines as the only peripheral, which increases the number of accessible connections.
When computer technology has changed, the network network architecture has changed with it, but not fast enough. Modern computing protocols and methods have caused some aspects of the system architecture to be irregular or outdated. As a result, if the IBM 3745/3746 Communications Controller contract has run 2002, it was not restored. The third -party system continued in the production of the controller and upgrading kits until 2009.
