LANforge ICE


LANforge ICE is a network emulator or WAN emulator. It can add impairments in a controlled and reproducible manner to aid in testing applications and network equipment that must operate over a network. LANforge supports many impairments: latency, bandwidth, jitter, packet loss, packet reordering and more.


It can act as a layer-2 pass-through device for easy insertion into the system under test. It also supports 802.1Q VLANs, router emulation, bridges and other network elements for more advanced emulation needs. Emulation speeds range from 10bps to 10Gbps, and some systems support more than 48 concurrent emulations. Click for a summary of impairments or a full listing of features.



LANforge Ice can be used to simulate a Wide Area Network with multiple locations and hops. LANforge ICE supports this with it's Netsmith feature.


The LANforge-ICEcap tool can probe a network and save the probed latency, packet loss and other values to an XML file that can be replayed by the LANforge-ICE WAN emulator. This allows for realistic WAN emulations based on real-world networks.


LANforge Ice Multi-port WAN Emulator - Great for testing online gaming!


The Multi-port WAN emulator is an excellent choice for high-density WAN emulation. The Multi-port is a set of 3 machines: One LANforge machine to do the WAN emulation, one Linux bridge machine to bridge the VLANs, and an off-the-shelf managed ethernet switch supporting 802.1Q VLANs.
