Speedtest.net, also known as Speedtest by Ookla, is a web service that provides free analysis of Internet access performance metrics, such as connection data rate and latency. It is the flagship product of Ookla, a web testing and network diagnostics company founded in 2006, and based in Seattle, Washington, United States.

unit used in telephony as a measure of offered load or carried load

cFosSpeed is a traffic shaping app for the Windows operating system. It installs a device driver on the network stack to perform stateful packet inspection on the application layer traffic. It has been noted as causing some issues with network connections, and can be difficult to uninstall.

bandwidth management technique

maximum rate of production or the maximum rate at which something can be processed

management of data rate

information rate that can be transmitted over a given bandwidth

provision of a service with no quality of service guarantee (e.g. computer networks, postal services)

Extension to the Internet Protocol to signal network congestion

iperf, also known as Iperf or iPerf, is a tool for network performance measurement and tuning. It is a cross-platform tool that can produce standardized performance measurements for any network. iperf has client and server functionality, and can create data streams to measure the throughput between the two ends in one or both directions. Typical iperf output contains a time-stamped report of the amount of data transferred and the throughput measured.

Bufferbloat is the undesirable latency that comes from a router or other network equipment buffering too many data packets. Bufferbloat can also cause packet delay variation (also known as jitter), as well as reduce the overall network throughput. When a router or switch is configured to use excessively large buffers, even very high-speed networks can become practically unusable for many interactive applications like voice over IP (VoIP), audio streaming, online gaming, and even ordinary web browsing.

iproute2 is a collection of userspace utilities for controlling and monitoring various aspects of networking in the Linux kernel, including routing, network interfaces, tunnels, traffic control, and network-related device drivers.

computer Networking Program

OpenNMS is a free and open-source network monitoring and network management platform written in Java. It provides fault management, performance data collection, service monitoring, event processing, and topology mapping. The project was started in July 1999 and registered on SourceForge as project 4141 in March 2000, making it one of the oldest open-source network management platforms.

In computer networks, goodput (a portmanteau of good and throughput) is the application-level throughput of a communication. In other words, goodput is the number of useful information bits delivered by the network to a certain destination per unit of time. The amount of data considered excludes protocol overhead bits as well as retransmitted data packets. This is related to the amount of time from the first bit of the first packet sent (or delivered) until the last bit of the last packet is delivered.

ALTQ (ALTernate Queueing) is the network scheduler for Berkeley Software Distribution. ALTQ provides queueing disciplines, and other components related to quality of service (QoS), required to realize resource sharing. It is most commonly implemented on BSD-based routers. ALTQ is included in the base distribution of FreeBSD, NetBSD, and DragonFly BSD, and was integrated into the pf packet filter of OpenBSD but later replaced by a new queueing subsystem (it was deprecated with OpenBSD 5.5 release, and completely removed with 5.6 in 2014).
