We offer a number of simulation solutions, however, a good starting point is to determine the network connection preferred. Most customers emulating latency, packet loss and other network impairments want to test using Ethernet connections, if so LANforge Ice should be the product you review. Other customers must create impairments between test routers, then the product of interest is the Router Delay Simulator.
LANforge Ice
The LANforge ICE configuration is used to simulate the core of a network, and will be used to test and verify applications and equipment that communicates through the core. LANforge ICE is able to emulate WAN networks with latency, throughput, and packet degradation.
LANforge-ICE emulates network connections such as T1, DSL, OC3, OC12, Satellite, Dial-Up and other limited speed network links. LANforge Ice can simulate a multi-router network or act as a bridge adding packet impairments.
LANforge Ice has a common graphical management interface and can be integrated with LANforge Fire a Network Traffic Generator. LANforge Ice Product Details
Router Delay Simulator
The Router Delay Simulator Plus (RDS+) allows users to test/stage critical DCE or DTE equipment for reliable network operation while simulating network delay times. The RDS+ provides a realistic simulation of physical network behavior with respect to time delays and bit errors. It supports user circuit rates up to OC-1 (51.84 Mbps) while providing delays from zero to a maximum of 4 seconds. Both continuous random and burst errors are supported.

Router Delay Simulator PLUS (RDS)
The RDS-PLUS is a modular, network link error and delay simulator that provides a realistic simulation of physical network behavior with respect to time delays and bit errors. The RDS-PLUS supports a wide range of interface types and speeds, ranging from 1200bps to over 50Mbps.
Router Delay Simulator (RDS)
For testing network transmission delays. The Router Delay Simulator (RDS) allows Router-to-Router connections at data rates up to 2.048Mbps while simulating network delays. The user selectable delays are for both data and control signals and range from 5 milliseconds(mS) to approximately 1250 mS, in 5 mS increments. The RDS allows users to test and pre-configure Routers (with software applications)and other critical DTE equipment for reliable network operation while simulating network delay times.
Router Delay Simulator, External Clock Option (RDS-ECO)
For testing network transmission delays utilizing an external clock source.
The Router Delay Simulator (RDS-ECO) allows Router-to-Router connections at data rates up to 5Mbps while simulating network delays. The user selectable delays are for both data and control signals and range from 5 milliseconds(mS) to approximately 1250 mS, in 5 mS increments. The RDS-ECO allows users to test and pre-configure Routers (with software applications)and other critical DTE equipment for reliable network operation while simulating network delay times.
Router Delay Simulator, Long Data Delays (RDS-LDD)
For testing network transmission delays utilizing an external clock source and Long Data Delays. Control Signals are not delayed.
The Router Delay Simulator with long data delays(RDS-LDD) allows DCE to DTE connections at data rates up to 5Mbps while simulating network delays. The user selectable delays are for bi-directional data and range from 10 milliseconds(mS) to approximately 2560 mS, in 10 mS increments. The RDS-LDD allows users to test and pre-configure critical DTE equipment such as Routers (with software applications) along with an attached modem, digital service unit(DSU) or other network access device for reliable network operation while simulating additional network delay times.
Frequently Asked Questions
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.
Can LANforge be used to simulate impairments between Routers?
Only when the connection between the routers is Ethernet, otherwise the Router Delay Simulator would be a better choice.
I want to test DCE or DTE equipment, what is the best solution?
The Router Delay Simulator Family allows users to test/stage critical DCE or DTE equipment for reliable network operation while simulating network delay times. RDS provides a realistic simulation of physical network behavior with respect to time delays and bit errors.
What type of interfaces does the Router Delay Simulator support?
The RDS family has two data port interfaces that support RS-232, RS-422/449, RS-530, V.35, X.21, DS1/E1, TTL, HSSI, DS3, E3, or STS-1. The data interfaces can be mix and matched where applicable, such as V.35-to-RS-530 connection.
Is the Router Delay Simulator software?
It is an appliance and software and can be configured with many options.
What are the network impairments RDS offers?
RDS provides a realistic simulation of physical network behavior with respect to time delays and bit errors. Allows the operator to determine the parameters for the type and rate of random and burst errors independently on each data path.
