NetDisturb

IP Network Impairment Emulator

Generate latency on IP networks
  • Performance & Acceptance Testing: Qualify & evaluate the behavior of IP equipment (phone, fax, gateway etc) & applications (audio & video streaming etc) on IP networks.
  • Configure & Control IP Equipment for Test & Verification: Define different QoS levels in an intranet or Internet environment to configure terminals, gateways & routers.
  • Test Laboratories: NetDisturb provides repeatable QoS on different flows using configuration mode and values (loss & delay) defined by the user in order to re-create real world problems in the lab.
  • Application Test: NetDisturb allows testing applications such as Voice over IP, streaming audio and video, and other distributed applications.
  • Emulation of Symmetric or Asymmetric Network Conditions (LAN, MAN, WAN): latency, jitter, packet loss, bandwidth limitations ... to test IP applications, services and products sensitive to various real conditions.

Product overview

NetDisturb is an IP network emulation software tool that can generate impairments (latency, delay, jitter, limited bandwidth, lost packets) over IP networks. NetDisturb allows the user to disturb flows on an IP network and to study the behavior of applications, devices or services in a disturbed network environment.

NetDisturb is inserted between two Ethernet segments (on the same IP network or different IP networks) and operates bi-directional packet transfer on Ethernet, Fast Ethernet and Gigabit network interface cards.

Disturbance may be generated by mathematical loss and delay laws which are applied to a flow defined by the user (generation and/or response).

Key Features

  • Client-Server Architecture based on the SOAP mechanism which uses the HTTP protocol and the XML format for the exchanges between the client and the server.
  • Netdisturb is an Ethernet bridge to avoid any network configuration.
  • Impairments: latency, loss, duplication, bandwidth limitation, delay and jitter, content impairment (mathematical laws and user-defined files).
  • 16 configurable IP flows per direction with optional trigger condition.
  • Aggregates of IP flows can be defined (set of IP flows sharing the same delay & jitter law).
  • Unidirectional or bi-directional packet impairments.
  • Change the law and mask on the fly.
  • Connections per IP flow: impairments are applied to the IP flow or to each connection of the IP flow.
  • Ethernet / Internet modes (packets out of sequence).
  • Easy to use and intuitive Graphical User Interface.
  • Statistics display and export detailed statistics in a file.
  • Command Line Interface (CLI) to use Netdisturb in test beds.
  • Ability to handle Ethernet Jumbo frames (payload up to 17976 bytes).
  • Ability to impair the remaining network traffic that could be either just the IP packets or all the Ethernet frames.

Configuration Options

Based on a Client-Server architecture, the NetDisturb software comprises of two parts, Server and Client, where the Server handles the impairment characteristics and the Client manages the Server using a simple graphical interface.

This allows two configurations where the Server and Client parts may be installed on the same PC host (local control) or the Server part resides on one PC and the Client part resides on a second PC (remote control). In this second configuration, the Client dialogs with the Server by using a WAN (for example: PSTN or ISDN) or LAN link. Both configurations require two identical Ethernet Cards for the Server.
