What type of protocol is used for SNMP communications?

Simple Network Management Protocol (SNMP) is utilized primarily for managing devices on IP networks and operates using the User Datagram Protocol (UDP). UDP is a connectionless protocol that allows for fast transmission of data packets without the need to establish a session or ensure delivery of each packet, making it suitable for scenarios where speed is crucial and occasional loss of information is tolerable. Since SNMP is often used for monitoring network devices, it can afford to drop some packets during communication without significantly affecting the overall functionality.

In contrast to protocols like TCP, which are connection-oriented and ensure reliable delivery of data packets, SNMP’s reliance on UDP allows it to perform efficiently in environments where low latency is essential. This reflects the nature of network management tasks, where timely updates can be more critical than the completeness of every single message.
