It supports TCP, UDP, ICMP and RAW-IP protocols, has a traceroute mode, the ability to send files between a covered channel, and many other features. Getting started with hping3

Cisco IP SLA (formally SAA) Viewing data as seen from a central location is only partially beneficial. Denika will work with your existing Cisco routers and switches, without deploying probes, to gather response time from multiple points around the network. In short, with Denika we can use your existing Cisco routers to perform the following: UDP Echo measures the response time from the Cisco router to any IP device. Jitter measures direct packet loss and Jitter. Jitter is inter-packet delay variance. It is very important when utilizing VoIP/Video. HTTP measures Round Trip Time (RTT) taken to connect and access data from an HTTP server (i.e. transaction time RTT). TCP Connect RTT DHCP measures the RTT taken to discover a DHCP server and obtain a lease from it. The IP address is then released. DLS+ measures the DLSw+ protocol stack and the network response time between DLSw peers. DNS measures the response time by taking the difference between the time token to send DNS requests and rec...
