LANforge Fire


Candela Technologies LANforge Fire , a network traffic generator, generates traffic for network testing, validation and audit. LANforge FIRE generates stateful network traffic and monitors packets for throughput and correctness.


LANforge FIRE generates and receives various network protocols. It is used to create load on a network or device under test. It reports statistics such as packets sent and received, latency, packet-loss and many other network characteristics.


LANforge supports real protocols and stateful TCP connections, so it can generate load against web servers, VOIP gateways, firewalls, load-balancers and many other network components. LANforge can virtualize network adapters and wifi station interfaces. It can also act as a router or group of routers supporting OSPF, RIP, BGP and Multicast (PIM, IGMP). LANforge supports IPv4 and IPv6.


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. LANforge run on Windows or Linux, with the most extensive feature set running on Linux. Click for a summary of traffic types or a full listing of features.


LANforge Fire can be purchased as software or comes in many configurations from portable to rack-mount appliances.



The WiFire 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.


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). Additional systems can be clustered for increased traffic generation capacity. 40 Gigabit options available.
