XML (English eXtensible Markup Language, an extensible markup language) is a text format designed to store structured data, to exchange information between programs, and to create more specialized markup languages ​​on its basis. XML-based systems typically require less development costs. Many service providers connected to CyberPlat use XML in the interaction protocol (MegaFon, Beeline, MTS, etc.). When working with service providers, CyberPlat uses its own interaction protocol, also based on this language.

A router or router or router (from the English router) is a network device that forwards network-layer packets between different network segments. Works at a higher level than the switch.

Cisco is the largest enterprise-level network router manufacturer today. At Cyberplat, Cisco equipment provides the functions of routers, firewalls, IP telephony, etc.
