So what is it SNMP? International standard, allowing, first of all, to integrate solutions from different manufacturers. Initially, their brand management algorithms set their own. But thanks to the development of SNMP, they got the opportunity to use unified teams, which stimulated the demand for manufactured network devices, and became an effective driver of market growth for the corresponding type of equipment.
