This paper provides a survey of Simple Network Management Protocol (SNMP)-related performance studies. Over the last 10 years, a variety of such studies have been published. Performance benchmarking of SNMP, like all benchmarking studies, is a non-trivial task that requires substantial effort to be performed well and achieve its purpose. In many cases, existing studies have employed different techniques, metrics, scenarios and parameters. The reason for this diversity is the absence of a common framework for SNMP performance analysis. Without such a framework, results of SNMP-related performance studies cannot easily be compared, extended or reused. It is therefore important to start a research activity to define such a framework. Such research activity should start from analysing previous studies on this topic to reveal their employed methods. In this survey we examine these studies by classifying and discussing them. We present techniques, approaches and metrics employed by these studies to quantify the performance of SNMP-based applications.
