Ostinato - Packet/Traffic Generator and Analyzer

Introduction
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.

Features
Runs on Windows, Linux, BSD and Mac OS X (Will probably run on other platforms also with little or no modification but this hasn't been tested)
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 a.k.a IP Tunnelling (6over4, 4over6, 4over4, 6over6)
TCP, UDP, ICMPv4, ICMPv6, IGMP, MLD
Any text based protocol (HTTP, SIP, RTSP, NNTP etc.)
More protocols in the works ...
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 realtime port receive/transmit statistics and rates
Capture packets and view them (needs Wireshark to view the captured packets)
Framework to add new protocol builders easily
