LANforge Product Overview


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. Perform functional, performance (load and stress), interoperability and scalability testing of networks and devices. Or, specify impairments to simulate WAN, Satellite or Wireless connections to understand how devices and applications will perform.


Network Traffic Generator


LANforge FIRE is used for Traffic Generation and 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 hundreds of Ethernet interfaces with unique MAC and IP addresses, allowing a single LANforge machine to appear as an entire subnet of machines.


The WiFi appliance can emulate hundreds of 802.11a/b/g/n/ac wireless stations. Several WiFi appliances will test for the impact of collisions. LANforge also supports the SIP VoIP messaging protocol, and can generate the RTP media stream as well. It can generate and receive traffic up to 999 Mbps per interface.


The 10 gigabit rack-mount appliance can generate and receive 99.8 % 10 Gbps Line Rate to bidirectional (about 40 Gbps total across the backplane). A 40 Gbps solution is also available at lower rates an is ideal for configuration test labs. Additional systems can be clustered for increased traffic generation capacity. 10 to 40 gigabit product details.


WAN Emulator

The LANforge ICE configuration is used to simulate the core of a network, and will be used to test and verify equipment that communicates through the core. The LANforge ICE platform is used to simulate T1, DS3, OC-3, OC-12, GigE, DSL, Satellite, Dial-Up, and other Wide Area Networks (WANs).

The LANforge GUI is a Graphical management interface to the LANforge system. The GUI connects to the LANforge server, which automatically discovers any LANforge Data Generators (also called 'cards') on it's management network. Because the connection to the server is a standard TCP/IP interface, the GUI can access the server remotely, even over a dialup connection.


  • LANforge uses Industry standard PC hardware and can run on Windows and Linux.
  • LANforge can be purchased as software, or it can also be purchased as appliances.
  • LANforge has a distributed architecture. All components can be installed on a single system or the components can be distributed across a number of systems.


The System: GUI, Manager and Resources

LANforge Architecture


The GUI, displays and records data reported by the Resource Manager and, generates control and configuration requests to the Resource Manager.The Resource Manager, only one in a single or clustered system, handles data collection, configuration, control, licensing and can also be a Resource. A Resource is a Network Traffic Generator (LANforge FIRE or Wi-Fire) and/or Network Emulator (LANforge ICE). More Resources = More Capacity.
