SNMP ("Simple Network Management Protocol") is nothing more than a standard language that computers use to control each other and report important information. Its advantage today is that a very large number of devices support it, enabling them to work together. There are several versions of SNMP: v1, v2c and v3 being the most referenced.
With SNMP being so widely used, there are many reasons to use a modern SNMP RTU, including saving you money.
SNMP RTUs describes Remote Telemetry Units that send SNMP traps. Often times, SNMP RTUs can also mediate non-SNMP devices to an SNMP manager as well, providing an integrated solution for your network needs.
SNMP RTUs, such as the NetGuardian product line can come in a variety of sizes, making it relatively easy to find one that fits the size of your site and your needs. First came:
The KDA which was superseded by the NetGuardian.
The NetGuardian 832A is a larger SNMP remote that is wireless and uses the most secure version of SNMP.
The NetGuardian 420 is a medium sized remote with a built-in terminal server.
The TrapRelay 64 can process SNMP Traps and latch relays as well.
If you have a small site, there are a variety of small SNMP solutions that will help you gain visibility of your entire network, such as:
SNMP RTU for TBOS; the NetMediator T2S.
