ostinato

Packet/Traffic Generator and Analyzer

Description

Ostinato is an open-source, cross-platform network packet crafter/traffic generator and analyzer with a friendly GUI. Craft and send packets of several streams with different protocols at different rates. Ostinato aims to be "Wireshark in Reverse" and become complementary to Wireshark.

Features:
 * Open, edit, replay and save PCAP files
 * Support for the most common standard protocols:
   - Ethernet/802.3/LLC SNAP
   - VLAN (with QinQ)
   - ARP, IPv4, IPv6, IP-in-IP IP Tunnelling (6over4, 4over6, 4over4, 6over6)
   - TCP, UDP, ICMPv4, ICMPv6, IGMP, MLD
   - Any text based protocol (HTTP, SIP, RTSP, NNTP etc.)
   - GRE
 * Modify any field of any protocol (some protocols allow changing packet
   fields with every packet at run time e.g. changing IP/MAC addresses)
 * User provided Hex Dump - specify some or all bytes in a packet
 * User defined script to substitute for an unimplemented protocol
   (EXPERIMENTAL)
 * Stack protocols in any arbitrary order
 * Create and configure multiple streams
 * Configure stream rates, bursts, no. of packets
 * Single client can control and configure multiple ports on multiple
   computers generating traffic
 * Exclusive control of a port to prevent the OS from sending stray packets
   provides a controlled testing environment
 * Statistics Window shows real time port receive/transmit statistics and rates
 * Capture packets and view them (needs Wireshark)
 * Framework to add new protocol builders easily
