LANforge supports Linux, Microsoft Windows and Solaris operating systems. LANforge on Linux is still the most precise, featureful and highest performing option.

LANforge FIRE Stateful Network Traffic Generator

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.

The LANforge system consists of a single manager process, and one or more traffic generator machines (resources). The resources are connected to the manager over a management network. Devices under test are connected to the non-management ports of LANforge systems. If needed, LANforge can also generate traffic on the management network.

The LANforge GUI may run on the LANforge machines or on the customer's PCs. The GUI should connect to the manager machine. Multiple GUIs can be used concurrently.

LANforge supports Linux, Microsoft Windows and Solaris operating systems. LANforge on Linux is still the most precise, featureful and highest performing option.

LANforge ICE is a network emulator. It 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.

Some users may want to simulate an entire LAN or WAN network. LANforge ICE supports this with it's Netsmith feature. Netsmith is a click-and-drag virtual network builder. It supports Bridges (switches) including spanning tree protocol, as well as OSPF, BGP, RIP and multicast routers. IPv4 and IPv6 routing protocols are supported, and the bridge will handle any Ethernet frame. LANforge is running real router and bridge software, so it can exchange messages with external equipment to populate routes and set up spanning trees. A screenshot from a Netsmith virtual router & emulation setup is found here.

LANforge ICE Use Cases

• Verify applications can run over WAN (wide area network) before migrating applications to remote data center. For a small cost up front, serious problems can be found in the lab before the customer sees them. Typical impairments would be delay (latency), bandwidth constraint, jitter and packet loss. Corruptions, packet reordering and complete link loss can also be applied.
• Affordably test multi-player games and other interactive real-time group applications. 48-port systems are available for around $1000 per port. Impairments include packet loss, delay, jitter, bandwidth constraint, and NAT (network address translation) emulation.
• Test streaming media CODECs and network stacks in a controllable manner. LANforge can emulate delay, jitter, packet loss, packet duplication, packet reordering and corruptions. All of these must be handled for streaming media based on UDP, for instance.
• Test LAN (local area network, typically Ethernet) based applications for adverse network conditions. LANs are normally fast and clean, but that just makes it harder to test for rare network problems. LANforge can drop, reorder, duplicate and corrupt packets. It can also generate realistic background traffic with the LANforge FIRE feature set.
• Verify data-replication services can function properly over degraded networks. LANforge can drop, reorder, and corrupt packets.
• Verify WAN accelerators and other data-compression tools provide the advertised improvements for your particular data flows. LANforge can limit bandwidth, add delay, and display actual throughput.
• Simulate large complicated networks. LANforge supports virtual routers, switches, multi-hop networks and more. Protocols supported include spanning-tree for switches and OSPF, BGP, RIP, IGMP, an PIM (Multicast) for routers.
• Do specific application testing by impairing only a certain subset of packets using the WanPath feature. Filters can be applied to almost any type of packet, including ARP, SIP, DNS, etc.

Standard Features

• General purpose WAN and Network impairment emulator: Validates stability and functionality of devices and programs over a wide variety of network conditions.
• Able to simulate DS1, DS3, OC-3, OC-12, OC-24, OC-48, GigE, DSL, CableModem, Satellite links and other rate-limited networks, from 10bps up to 5 Gbps speeds (full duplex).
• Can modify various network attributes including: network-speed, latency, jitter, packet-loss, packet-reordering, and packet-duplication.

Advanced Features

• Supports Packet corruptions, including bit-flips, bit-transposes and byte-overwrites.
• Supports WanPath feature to allow configuration of specific behaviour between different IP subnets or MAC addresses using a single pair of physical interfaces. *
• WanPaths can also impair packets based on an arbitary filter that is created using the powerful and well documented tcpdump filter syntax. *
• Supports WAN emulation across virtual 802.1Q VLAN interfaces for more efficient use of valuable physical network interfaces.
• Supports routed and bridged mode for more flexibility in how your configure your network and LANforge ICE. Virtual routers can be configured with the Netsmith tool. Supported routing protocols include: static, OSPF, RIP, OLSR, BGP, and Multicast (PIM, IGMP). Most protocols support both IPv4 and IPv6. LANforge ICE on Windows and Solaris supports only bridged mode currently.
• Supports 'WAN-Playback' allowing one to capture the characteristics of a live WAN and later have LANforge ICE emulate those captured characteristics. The playback file is in XML format, and can be easily created by hand or with scripts. The LANforge ICEcap tool can be used to probe networks and automatically create the XML playback file.
• Allows packet sniffing and network protocol decoding with the integrated Wireshark protocol sniffer.
