Some tools measure traffic by sniffing and others use SNMP, WMI or other local agents to measure bandwidth use on individual machines and routers. However, the latter generally do not detect the type of traffic, nor do they work for machines which are not running the necessary agent software , such as rogue machines on the network, or machines ...
It allows the user to see traffic load on a network over time in graphical form. It was originally developed by Tobias Oetiker and Dave Rand to monitor router traffic, but has developed into a tool that can create graphs and statistics for almost anything. MRTG is written in Perl and can run on Windows, Linux, Unix, Mac OS and NetWare.
To test forwarding performance, IP load testers typically surround a router with simulated Internet traffic. This function is called packet blasting, and there are a couple of popular methods. The first method approximates real Internet traffic by using a representative mix of packet lengths, usually referred to as IMIX. Another popular ...
ping is a computer network administration software utility used to test the reachability of a host on an Internet Protocol (IP) network. It is available for virtually all operating systems that have networking capability, including most embedded network administration software.
NetFlow is a feature that was introduced on Cisco routers around 1996 that provides the ability to collect IP network traffic as it enters or exits an interface. By analyzing the data provided by NetFlow, a network administrator can determine things such as the source and destination traffic, class of service, and the causes of congestion.
Bandwidth test software is used to determine the maximum bandwidth of a network or internet connection. It is typically undertaken by attempting to download or upload the maximum amount of data in a certain period of time, or a certain amount of data in the minimum amount of time.
Once the router is set up with a VPN, it encrypts the internet traffic of all connected devices. Installing or managing VPN software on every device is unnecessary with a VPN router.
IMIX profiles are based on statistical sampling done on Internet routers, and are published in various levels of granularity, such as "simple" and "complete." Although the actual Internet traffic mix has changed over time, the standardized IMIX profiles used for testing have not been updated accordingly because the IMIX test results need to be ...
