Netperf is a software application that provides network bandwidth testing between two hosts on a network. It supports Unix domain sockets, TCP, SCTP, DLPI and UDP via BSD Sockets. [1] Netperf provides a number of predefined tests e.g. to measure bulk (unidirectional) data transfer or request response performance.
iperf, 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.

XDP (eXpress Data Path) is an eBPF-based high-performance data path used to send and receive network packets at high rates by bypassing most of the operating system networking stack. It is merged in the Linux kernel since version 4.8. [2] This implementation is licensed under GPL. Large technology firms including Amazon, Google and Intel ...

This material includes pornography, information on religion, and political dissent. [25] Chinese network ISPs use DPI to see if there is any sensitive keyword going through their ...
perf (sometimes called perf_events [1] or perf tools, originally Performance Counters for Linux, PCL) [2] is a performance analyzing tool in Linux, available from Linux kernel version 2.6.31 in 2009. [3]
Netfilter is a framework provided by the Linux kernel that allows various networking-related operations to be implemented in the form of customized handlers.Netfilter offers various functions and operations for packet filtering, network address translation, and port translation, which provide the functionality required for directing packets through a network and prohibiting packets from ...
