LANforge Ice |

LANforge Ice simulates WAN or LAN latencies.
LANforge ICE is a WAN or Network impaiment simulator.
LANforge ICE is used to simulate the core of a network, and is used to test and verify equipment that communicates through the core. The LANforge ICE platform is used to simulate T1, DS3, OC-3, OC-12, GigE, DSL, Satellite, Dial-Up, and other Wide Area Networks (WANs).

LANforge Ice can be used to simulate a Wide Area Network with multiple locations.

Netsmith is a drag-and-drop virtual network builder. It can support virtual routers, emulated network links, bridges (switches), virtual and physical interfaces, and more. When using routers, it supports static routing for IPv4 and IPv6, OSPF routing for IPv4 and IPv6 and IPv4 multicast routing protocols. LANforge-FIRE stateful traffic generating connections and LANforge-ICE network emulations are easily placed in the virtual networks. The virtual routers can connect to external OSPF and multicast routers and static subnet routing for easy integration into your network.
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 Fire can be purchased as software or an appliance in a standard or custom configurations.
LANforge Ice
A wide area network (WAN) subjects applications to network impairments such as congestion, latency or jitter. These connections such as T1, DSL or Wireless can impact an applications scalability, performance and service level compliance.
Some products use mathematical network models to predict performance, LANforge Ice simulates the actual connection allowing you to test during application development or before an application is deployed.

LANforge Ice Network Packet Impairments
Simulates WAN or LAN latencies
| Features and Packet Impairments | Description |
| Bi-Directional | Simulates different connection types on each side of a WAN connection, T1, DSL, Cable, Wireless or Satellite. |
| Pass Through | Adds impairments as packets are received in one Ethernet interface and transmitted out the other interface. |
| 802.1Q VLAN | Able to bridge 802.1Q VLAN Interfaces. |
| Router | Allows LANforge Ice to act like a router. |
| Buffer | Emulates the smoothing buffer found on equipment used in Wide-Area-Networks. The buffers are implemented to smooth bursty traffic so that packets are not needlessly dropped. |
| Delay/Latency | The time it takes in mili-seconds for a packet of data to get from one designated point to another. |
| Jitter | Simulates the variation in the time between packets arriving, caused by network congestion, timing drift, or route changes. |
| Drop | Simulates the disappearance of a packet that was transmitted or ought to have been transmitted. Packets can also be dropped in a burst or specifically every xth packet. |
| Duplicate | Simulates duplication occurs when one packet becomes two (or more) identical packets. Can also specify every xth packet. |
| Re-Order | Packets are moved out of order from their original sequence. This packet delay has an earlier packet being delayed greater than a subsequent packet. The subsequent packet will arrive before the earlier packet. |
| Bit Error | Inserts random or periodic errors in either the payload only or the complete packet. Supports packet corruptions, including bit-flips, bit-transposes and byte overwrites. Able to specify multiple corruptions. |
| Checksum | Recalculates the IP, UDP, and TCP checksum for a packet after applying the corruption. This will allow the corrupted packet to be accepted by the stacks on the receiving machine as if the data were actually valid. |
Can LANforge Ice be purchased as software?
Yes, or it can also be purchased as an appliance.
What type of hardware and operating system is required by LANforge Ice?
LANforge Ice uses Industry standard PC hardware and can run on Windows and Linux.
How is LANforged Ice Licensed?
WAN Emulation Products are licensed by the bps rate supported.
What is the simplest configuration for LANforge?
LANforge works as a bridge and adds network impairments as specified to the packets. It is ideal for testing Client/Server application performance.
What is the highest bps rate supported by LANforge Ice?
LANforge Ice can support up to 2.4Gbps bi-directional, which is equivalent to an OC48 connection.
Can LANforge Ice be used to simulate a Wide Area Network with multiple locations?
LANforge Ice can be configured with many NIC ports, each port can represent a virtual router, and each virtual router can be linked to other virtual routers (WANlinks). Each WANlink can be configured for speed and the network impairments desired. Special versions have been configured for the gaming industry to test Internet games.
What are some of the network impairments LANforge Ice offers?
LANforge Ice can modify various network attributes including: network-speed, latency, jitter, packet-loss, packet reordering, and packet-duplication. It also supports packet corruptions, including bit-flips, bit-transposes and byte-overwrites.
