'''Netperf''' is a software application that provides [[network bandwidth]] testing between two hosts on a network. It supports [[Unix ___domain socket]]s, [[Transmission Control Protocol|TCP]], [[SCTP]], [[DLPI]] and UDP via BSD Sockets.<ref>{{cite conference | title=Algorithms and Architectures for Parallel Processing | publisher=Springer |author1=Sang-Soo Yeo |author2=Jong Hyuk Park |author3=Ching-Hsien Hsu |author4=Laurence Tianruo Yang | year=2010 | conference=10th International Conference, ICA3PP | pages=372 | isbn=9783642131189}}</ref> Netperf provides a number of predefined tests e.g. to measure bulk (unidirectional) data transfer or request response performance.

'''Netperf''' is the de-facto standard for network bandwidth testing between two hosts on a network. It blasts TCP data from a client host to a server host. This is different than transferring a file over the network, as you avoid any disk bottlenecks, and are using a standardized client and server for testing.

A particular feature of Netperf is that it runs each test multiple times and reports not only the results but also reports the Confidence Interval. It can test both TCP and UDP. It was written in C and works on most UNIX variants, including BSD, System V, Linux, and MacOS.

Netperf is a benchmark that can be used to measure the performance of many different types of networking. It provides tests for both unidirecitonal throughput, and end-to-end latency. The environments currently measureable by netperf include:

TCP and UDP via BSD Sockets for both IPv4 and IPv6

DLPI

Unix Domain Sockets

SCTP for both IPv4 and IPv6

Netperf was originally developed by Rick Jones at [[Hewlett Packard]] in Cupertino, CA.<ref>{{cite book | title=Troubleshooting Microsoft technologies: the ultimate administrator's repair manual | publisher=Addison-Wesley Professional | author=Wolf, Chris | year=2003 | pages=119 | isbn=9780321133458}}</ref>
