Description: X.25 network is a network that uses the X.25 protocol for packet-switched communication. This protocol was designed to enable efficient and reliable data transmission over packet-switched networks. X.25 provides a set of services that ensure data delivery, error correction, and flow control, making it a robust option for applications requiring high availability and security in information transmission. The main features of X.25 include data segmentation into packets, node identification in the network, and the ability to establish virtual connections between devices. Although largely surpassed by more modern technologies, X.25 remains relevant in certain environments where stability and security are paramount. Its architecture allows for security orchestration, as it facilitates the implementation of protective measures in data transmission, which is crucial in today’s cybersecurity context. Additionally, its design allows for automation and incident response, as systems can be configured to react efficiently to failures or intrusion attempts.
History: The X.25 protocol was developed in the 1970s by the International Telecommunication Union (ITU) and standardized in 1976. Its creation was driven by the need for more efficient and reliable data communication in telecommunications networks. Over the years, X.25 evolved and was implemented in various applications, especially in business and government environments. During the 1980s and 1990s, it was widely used for communication between terminals and computing systems, although over time it was replaced by more advanced technologies such as TCP/IP.
Uses: X.25 is primarily used in applications requiring reliable and secure data communication, such as in banking systems, telecommunications networks, and critical data services. It has also been used in connecting terminals to central systems and in communication between devices in industrial environments.
Examples: A practical example of X.25 is its use in ATM networks, where secure and reliable communication is required for the transmission of financial data. Another example is its implementation in aviation systems, where stability and security are essential.
