Performance and Application Analysis Tool NetDoppler™ performs route discovery, latency tests, and throughput tests to remote hosts. NetDoppler builds a tree of IP nodes representing the packet path and is ready to perform serious testing and baselining from the moment you install it. There's no need for specialized software such as SNMP or remote monitoring agents! NetDoppler also provides extensive statistics and graphing functions to easily interpret your results.

Version 1.1.1.69 For Windows

Features

NetDoppler utilizes several features of the ICMP Echo (Ping), IP and DNS protocols to perform a variety of tasks and tests on remote hosts to help you check latency and throughput as well as isolate problems. NetDoppler provides extensive statistics and graphing functions to easily interpret your results. Unique to NetDoppler is the ability to perform throughput tests based on both a single packet as well as packet streams to a remote host and back. This allows you to test the effect of latency on a client/server application that sends a single packet and receives a single reply (i.e. a 1:1 command/reply window) vs. an application that is able to send and receive multiple packets in succession to "fill the pipe" between the client and server.

Latency

NetDoppler performs latency measurements by reporting the time it takes a host to respond to a small Ping packet. Latency is an estimate of the minimum amount of time it takes for a small amount of data to go from your computer to the host being measured, and for that host to process the data and send a response back to your computer. High latencies may indicate a slow network connection such as over a dial-up modem, network congestion, bogged down routers or switches, or a slow or busy host.

Throughput

Throughput is the rate at which data can be transferred over a node or along a network path. NetDoppler performs throughput measurements in two ways, either of large data packets streamed to a target host or of a series of smaller packets. Tests are easy to configure and can be done in a quick or a sustained fashion.

Route

NetDoppler summarizes the data for all the hops along a route traced from the active My Computer starting point to the selected host. The Route graph shows the latencies, the throughputs, or both for all the hops up to and including the selected host.
