IP网络干扰抖动时延模拟器 —— NetDisturb


NetDisturb software is a network emulator software (IPv4 & IPv6) generating user-defined impairments: latency, delay, jitter, bandwidth limitation, loss, duplication, modification of the packet content and more…

NetDisturb allows disturbing flows over IP networks helping to study the behavior of applications, devices or services in a “disturbed” network environment. NetDisturb is inserted between two Ethernet segments acting as a bridge and operates bi-directional packet transfer on Ethernet, Fast Ethernet and Gigabit network interface cards.

No need to buy expensive hardware, use NetDisturb software such as hundreds customers around the globe!


Development assistance and debug of automatons for IP equipments: particularly for Set-Top Boxes operating in cable or telecom environments.



Performance & Acceptance Tests: Qualify and evaluate the behavior of IP equipments (phone, fax, gateway, set-top box, IMS core, call server, application server, residential gateway, ADSL wireless router and more…), and etc.) and applications (audio and video streaming) over IP networks.





Configuration and control of IP Equipments for product verification and test: Define different QoS levels in an Intranet or Internet environment to configure terminals, gateways and routers.



Test Laboratories: NetDisturb provides repeatable QoS on different flows using configuration mode and values (loss, duplicate, delay, packet content impairment) defined by the user, and so re-create real world problems in the lab.



Applications test: NetDisturb allows testing applications such as Voice over IP, Fax over IP, audio and video streaming, and other distributed applications.



Emulation of symmetric or asymmetric network conditions found on the Internet and enterprise networks (LAN, MAN, WAN): latency, jitter, packet loss, bandwidth limitation, and more… to test IP applications (VoIP, audio & video streaming, etc.), services and products sensitive to various real conditions.



Simulation of satellite links with important delays and limited bandwidth

and more…
