Network device manufacturers and end users desire stateful network traffic generators to test devices and associated configurations. Packets, specifically defined for the test, are sent from end points through the device or network under test, and results are recorded on throughput, packet loss and latency between the end points. High levels of traffic generation can be used to stress and load test the devices or network under test. Traffic Generator’s may be deployed in the field for throughput testing or troubleshooting.

Candela Technologies LANforge Fire and ICE, are ideal for field or lab, and use a common GUI to provide both network traffic generation and impairment (WAN Emulation).

LANforge Fire generates traffic for network testing, validation and audit

Traffic Genertaion for 100Mbps, 1 Gigabit and 10 Gigabit

LANforge Traffic Generation simulates the edge of the network under test. LANforge FIRE can generate FTP, HTTP, VoIP (SIP, RTP, RTCP), TCP/IP, UDP/IP, Ethernet and custom payloads. It supports 802.1Q VLANs, and can also emulate 250 to several thousand Ethernet interfaces with unique MAC and IP addresses, allowing a single LANforge machine to appear as an entire subnet of machines.

With the Armageddon feature, LANforge can generate and receive traffic up to 99% of the interface (100Mbps, 1 Gig and 10 Gig).

For VoIP testing, LANforge generates SIP messaging protocol, and can generate the RTP media stream traffic as well.

The WiFi testing solution can emulate from 31 to 400 802.11a/b/g/n wireless stations.

LANforgeF40AA - WAN SIP Call Generator(Up to 10 call pairs $1,189.00)

The LANforgeF40AA solution comes with a pair of low-power and affordable appliances, each with a single 10/100 Ethernet port, and together capable of up to 40Mbps of bi-directional traffic. It is targeted at users who wish to test between WAN connections or two end points on a network with up to 40Mbps of bi-directional traffic. Also capable of testing QoS and generating IP port specific traffic.

The LANforgeF40AA is based on the Raspberry PI B platform, running the Linux Raspbian OS. The LANforgeF40AA has no moving parts and is about the size of a deck of cards. It has HDMI, Keyboard, and Mouse interfaces for easy console/desktop access to the system. Also required is a separate PC running the LANforge GUI on the same network to manage the LANforge systems.

Single units may be purchased for additional end point locations. Product code no. is LANforgeF40ME

Network Traffic Generator

LANforge Fire Configuration

LANforge Fire

Network traffic on business networks includes multi-tier applications, user loads from the web, e-mail, web conferencing, streaming media and VoIP. Network devices such as switches or routers are called upon to support increasing traffic with a wide array of protocols, packet sizes, addresses, traffic patterns, VLAN segmentation and QOS.

LANforge Fire provides a test solution to generate traffic to validate that the devices will be able to perform when making configuration changes, adding users or applications.

  • Validates stability and data throughput on devices under evaluation.
  • Useful for testing any network - Ethernet, Wireless and VoIP
  • Cost effective solution for testing efforts requiring many data-generating ports or simulation of multiple mIP's and protocols.
  • Turn key solution. The LANforge systems can come pre-installed and configured to customer requirements.
  • Modular architecture allows you to leverage existing LANforge investment as your need for capacity increases.
  • Ease of use - Manage entire LANforge installation through one interface, from anywhere on the network.
