Mausezahn (German pronunciation: [ˈmaʊ̯zəˌʦaːn], German for "mouse tooth") is a fast network traffic generator written in C which allows the user to craft nearly every possible and "impossible" packet. Since version 0.31 Mausezahn is open source in terms of the GPLv2.
A packet generator or packet builder is a type of software that generates random packets or allows the user to construct detailed custom packets. Depending on the network medium and operating system, packet generators utilize raw sockets , NDIS function calls, or direct access to the network adapter kernel-mode driver .
For example, an HTTP traffic generator simulates the download of a web-page, consisting of a number of small objects (like images). A TCP stream (that's why TCP generator is a must in this model) is used to download these objects according to HTTP1.0 or HTTP1.1 specifications. These models take into account the details of these protocols' work.
This is a list of TCP and UDP port numbers used by protocols for operation of network applications. The Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP) only need one port for bidirectional traffic. TCP usually uses port numbers that match the services of the corresponding UDP implementations, if they exist, and vice versa.
Troubleshooting network devices that use network clients (devices that "phone home" via UDP, TCP, or SSL—Packet Sender can capture these requests) Testing and development of new network protocols (send a packet, see if device behaves appropriately) Reverse-engineering network protocols for security analysis (such as malware)
QUIC was developed with HTTP in mind, and HTTP/3 was its first application. [35] [36] DNS-over-QUIC is an application of QUIC to name resolution, providing security for data transferred between resolvers similar to DNS-over-TLS. [37]
Some protocol analyzers can also generate traffic. These can act as protocol testers. Such testers generate protocol-correct traffic for functional testing, and may also have the ability to deliberately introduce errors to test the device under test 's ability to handle errors.
TCP offload engine (TOE) is a technology used in some network interface cards (NIC) to offload processing of the entire TCP/IP stack to the network controller. It is primarily used with high-speed network interfaces, such as gigabit Ethernet and 10 Gigabit Ethernet, where processing overhead of the network stack becomes significant.
