Through an intuitive, browser-based graphical interface, you can install the IPNetSim™ and begin testing within minutes.

Terrestrial:

Emulate the bandwidth, delay, and loss characteristics of T1, E1, T3, E3, OC-3, ATM, xDSL, Frame Relay, and dial-up modems. Use IPNetSim™ to determine how much bandwidth you need to keep your applications running smoothly, and the most cost-efficient WAN technology to meet your performance requirements.
Wireless:

Mobile wireless networks offer great convenience for professionals on the road and fixed wireless can be a boon for disperses communities, but performance may not match terrestrial options. Use IPNetSim™ to find out if wireless solutions fit your needs.
Internet:

Use IPNetSim™ to find out beforehand conditions of e-commerce connections when the Internet is busy or the quality of IP calls and plan for appropriate counter measures.
Satellite:

With latency in excess of 500 ms and bit error rates as high as 1x10-6, satellite networks can create havoc for protocols and applications. The IPNetSim™ is especially designed to accommodate the long delays and high error rates of satellite networks, and includes the ability to simulate bit errors in addition to packet loss.

Main Features

  • Easy to Use-no software, plug and play-No software required to install. Just plug in the Ethernet cables and specify the link conditions for emulation. The Ajax-based GUI combines the responsiveness of an application with the convenience of a standard Web browser interface.

  • Remote access via Ethernet management port

  • Bandwidths up to 1 Gbps - With IPN400, emulate WAN bandwidths up to 1 Gbps in each direction per link to an aggregate of 8 Gbps at full line rate.

  • Multiple Links  - With the ability to emulate 8 separate, independent links, the IPN400 is a compact and cost-effective alternative to multiple WAN emulation appliances. Independent pairs of Ethernet interfaces for each link make configuration of multiple links as easy as a single link.
  • Delay from 1 ms to 10 seconds - perfect for satellite delay modeling-Emulate latency in constant, normal or uniform distribution in either direction starting from 1ms up to 10secs.

  • Precise Error Insertion - Emulate bit error rates as low as 1x10-14. Specified loss can be packet loss rate, bit error rate, or both.

  • Congestion Emulation - Determine the effect of congestion on bandwidth and jitter-sensitive applications by specifying the background link utilization and its burstiness.

  • Jumbo Frames - Test with Ethernet frames of up to 9 KB.
  • Unique Scheduler for modeling different error scenarios - IPNetSim™ Scheduler allows any combination of emulation parameters to vary over time, making link outages, variable bandwidths links, route flapping, satellite rain fade, and wireless interference with high-flexibility. IPNetSim™ can automatically adjust to the link conditions between specified end states.

  • Traffic Monitor for visibility into traffic flow through the box - Provides a visual display of the current traffic conditions, including throughput graphs, link statistics. Up to 24 hours of statistics can be downloaded for analysis.
  • Unsurpassed precision - Simulates link bandwidth with microseconds resolution and performs bit error rate probability calculations with 256-bit values to ensure correct, precise, and accurate error distribution

  • Bridging or Routing Modes - IPNetSim™ can be configured as a bridge or router for easy integration with any test configuration.
  • Command Line Interface for Automated testing - Series of tests can be run using IPNetSim™ scheduler or the command line interface, which makes IPNetSim™ ideal for automated product testing.

  • Match real link behaviour - adjustable framing overhead allows accurate emulation of any layer. Queuing delay can be modeled with queues set in packets, bytes, or milliseconds to match actual WAN hardware

  • Advanced emulation parameter - Verify that applications and networking equipment properly handle anomalous packet reordering and duplication conditions without inducing stability or performance problems. Adjust the framing overhead and maximum queue depth to match real link behaviour.

  • Copper and Fiber Gigabit Ethernet interfaces - Connect using either RJ-45 copper or modular fiber/SFP Gigabit Ethernet for convenient installation on copper or fiber-based networks.

Applications

  • Network Validations:

    You have to choose between terrestrial wireless, satellite, and other WAN technologies to connect between offices across the globe. The cost trade-offs are easy to quantify, however, the parameters such as delay, jitter, and loss affect performance of critical applications. Estimating the bandwidth required to keep applications running can be known by emulating the links in the lab with different conditions and demonstrating performance to all decision makers before the choice is made.

  • Equipment Testing:

    Use IPNetSim™ to find out if addition of equipments such as accelerator, compression device, traffic shaper, cache, or application proxy can improve the performance of the network before you purchase.

  • Troubleshooting:

    Use IPNetSim™ in the lab to pinpoint the cause in the application failure and validate solutions without disrupting the production network. With record & playback feature of IPNetSim™, one can capture the conditions & reproduce the delay / loss characteristics of the live link in a repeatable test environment.

  • Application Testing/ QA Testing:

    Use IPNetSim™ to test if the networking equipment, software, and client/server based applications works under any condition on a local network as well as from a remote place located across the town or on the other side of the world before your users complain. With the ability to emulate 4 independent links, the IPN400 allows 8 individual developers to use the device simultaneously, saving time & money.

  • Website Performance:

    See your website as your users experience and make sure its responsive. Verify that your e-commerce system does not leave your customers hanging when their link goes slow

  • VoIP:

    Voice over IP sounds perfect in demonstrations on the LAN, but quality diminishes with latency, jitter and packet loss. Test VoIP network using IPNetSim™ under real-world conditions to verify if it meets the quality requirements before you deploy.

Operation

The IPNetSim™ is managed through a browser-based Internet Explorer version 6 or later, or Mozilla Firefox GUI over an Ethernet connection to a dedicated management interface.

Initial configuration of the management interface requires either:

  • PC running a supported web browser that can be configured and placed on the 10.0.0.0/255.0.0.0 network.

  • PC with an RS-232 serial port running HyperTerminal or other terminal emulation software.

IPNetSim™ can be installed between two LAN segments as shown in the diagram. Depending on configuration, the IPNetSim™ acts as either a transparent learning bridge or a router between the Ethernet segments connected to the LAN A and LAN B ports of the unit. Frames received on one port are subjected to the emulated WAN conditions before being forwarded to the other port.

Emulation conditions are configured on the IPNetSim™ GUI and operate independently in each direction.

When functioning as a bridge, the IPNetSim™ is not limited to emulating IP networks, but can emulate any type of network so long as the traffic is encapsulated in Ethernet. In addition to IP, the IPNetSim™ can be used with IPv6, IPX, AppleTalk, SCPS, and proprietary network and transport layer protocols.

FAQs

  • Who uses the IPNetSim™?

    The IPNetSim™ is designed for anyone who needs an accurate, easy-to-use, cost-effective way to simulate WAN conditions, including:

    • Corporate IT Managers
    • Application and equipment developers
    • Military network developers
    • Sales and SE professionals
    • Networking equipment resellers and system integrators
    • Q/A teams
    • Test labs

  • Can the IPNetSim™ emulate long delays?

    Yes. The IPNetSim™ was designed with satellite and other long latency conditions in mind and can handle delays of up to 10 seconds in each direction.

  • Can the IPNetSim™ emulate individual end nodes?

    No. The IPNetSim™ emulates the WAN link itself. It is not a traffic generator.

  • How does the IPNetSim™ differs from competing WAN emulation solutions?

    Until now, there were only two alternatives: high-end WAN emulators and freeware. High-end WAN emulators offer a wide array of features, but their prices puts them out of range of most users while their complexity make them difficult to use. Although freeware has no upfront cost, the time wasted in installation and configuration of the source code makes them unproductive, and the resulting systems are constrained in precision and performance.

    The IPNetSim™ is the culmination of a mission to offer the precision and performance of a high-end WAN emulator without the cost, designed to be far easier to use than anything else available.
