Projects / LANforge FIRE & ICE


LANforge is a unified multi-protocol network traffic generation and WAN emulation application. It allows users to generate real world customer traffic in a controllable manner. The WAN emulator allows the injection of latency and other network oddities like dropped, duplicated, and re-ordered packets. LANforge includes a drag-and-drop virtual network builder that supports virtual routers, WAN links, traffic-generating nodes, and more. It provides a scriptable command line interface with Perl libraries as well as a graphical user interface.

Recent releases

  •  01 Dec 2011 20:45

    Release Notes: This release includes improved wireless traffic generation and some network emulation stability fixes relating to packet capturing. The WiFi stations can now be set to a mix of /a, /b, /g, and/or /n. Rates and other settings can be set on each interface. Third-party traffic can be bridged on to the virtual stations based on MAC address or IP address.

      Release Notes: This release includes improvements for file I/O, packet replay, VoIP, and GUI real-time graphing. The LANforge-ICE network emulator has performance improvements to sustain at least 5Gbps bi-directional flow on modern high-end hardware. Virtual routing supports RIP and OLSR. The GUI supports batch-modify, allowing the user to easily apply the same setting(s) to many endpoints and ports at the same time.

        Release Notes: This release has better support for File I/O testing: auto-mount, auto-unmount, and verify mount for NFS, NFSv4, CIFS, and iSCSI file systems. The GUI has been improved to allow batch-creation of most tests to aid creation of large numbers of connections without having to use a CLI script. This release has been upgraded to Linux kernel

        •  30 Jan 2009 18:37

          Release Notes: LANforge now supports the IPv6 protocol. The Windows build more closely matches the feature set of Linux, and Solaris x86 and SPARC are supported as well. The graphical network builder supports virtual routers, including OSPF and subnet routing for IPv4 and IPv6, network impairments, traffic-generating nodes, and more. The GUI and other components have been improved to scale past 4000 concurrent connections on modern hardware. The network emulator and traffic generator support 10G networks.

          •  05 Dec 2006 19:27

            Release Notes: This release improves SIP to handle Re-Invite messages, cleans up call counters, and fixes the jitter buffer to handle reorders, duplicates, over-runs, under-runs, and various other problems. It improves kernel locking for the wanlink module, giving increased stability and performance up to 990Mbps. HTTP connections can use caching systems such as squid.
