Candela solutions include both network emulator LANforge ICE and traffic generator LANforge FIRE. LANforge ICE can add impairments in a controlled and reproducible manner to aid in testing applications and network equipment that must operate over a network. LANforge supports many impairments: latency, bandwidth, jitter, packet loss, packet reordering and more. It can act as a layer-2 pass-through device for easy insertion into the system under test. It also supports 802.1Q VLANs, router emulation, bridges and other network elements for more advanced emulation needs. Emulation speeds range from 10bps to 5Gbps, and some systems support more than 48 concurrent emulations. LANforge FIRE generates and receives various network protocols. It is used to create load on a network 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.
