NetDisturb - Enhanced Impairment Simulator

Simulate impairments like jitter, latancy, delay and L7 protocols

NetDisturb is an IP network emulator software that can generate impairments over IP networks (IPv4 and IPv6) such as: latency, delay, jitter, bandwidth limitation, loss, duplication and modification of the packets. packets) and more...

  • Features
  • 16 configurable flows per direction
  • Ability to impair the remaining network traffic that could be either only the IP packets or all the Ethernet frames
  • Accuracy = 1 millisecond resolution
  • Aggregates of flows can be defined (set of flows sharing the same Delay and Jitter characteristics
  • ARP (ARP Operation Code)
  • Change the impairment law on-the-fly for a flow
  • 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
  • Command Line Interface (CLI) to use NetDisturb in test beds
  • Connections per flow: impairments are applied to the flow or to each connection of the flow
  • DHCP (DHCP Message Type)
  • DNS (DNS Message Type, DNS Message Operation)
  • Ethernet / Internet modes (Out-of-Sequence packets)
  • Ethernet Jumbo frames supported (payload up to 17,976 bytes)
  • FTP (FTP Command, FTP Returned Status)
  • Impairments based on protocol primitives:
  • Impairments: Latency, Loss, Duplication, bandwidth limitation, Delay and Jitter, Content impairment (mathematical laws or user-defined files)
  • NetDisturb is an Ethernet bridge to avoid any network configuration
  • pattern trigger
  • Predefined filter parameters based on the main protocol header fields (MAC, MPLS, VLAN, IP, TCP and UDP headers) and user-defined pattern filter
  • Simultaneous support of IPv4 and IPv6
  • Specific Key Features
  • starting time after delay or number of packets received
  • Statistics display and export detailed statistics into a file
  • stop impairments after number of received packets or elapsed time,loops and more...
  • Symmetric or Asymmetric bandwidth limitation with router simulation
  • Unidirectional or bi-directional packet impairments
  • use of standard Ethernet Network Interface Cards up to 1 Gbps
  • User-defined rules for disturbances:
  • Very easy to use and intuitive Graphical User Interface
  • Applications
