Candela LANforge-ICE: Network Emulator
Candela LANforge-ICE is able to emulate networks of various latency, throughput, and packet degradation. The feature highlights include being able to set the throughput, latency, jitter, packet loss, packet duplication, and packet reordering characteristics. LANforge-ICE can also apply these characteristics to particular packet flows using the WanPath feature. LANforge-FIRE and LANforge-ICE can be used as a single integrated product and can run on the same machine at the same time. It is easy to add new machines to a LANforge system allowing it to scale to meet your growing needs!

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 9.8Gbps, and some systems support more than 48 concurrent emulations. Some users may want to simulate an entire LAN or WAN network. LANforge ICE 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.
  • Allows users to create several virtual routers and paths between two physical ports
  • Various router protocols like OSPF, RIP, BGP and others can programmed
  • Various impairments can be created on the virtual router links and the router protocols can be tested
  • Simulate DS1, DS3, OC-3, OC-12, GigE, DSL, Cable-Modem, Satellite links and other rate-limited networks, from 10bps up to 10Gbps speeds (full duplex)
  • Can modify various network attributes including: line-speed, latency, jitter, packet-loss, packet-reordering and packet-duplication
  • Supports Ethernet packet corruption with option to recalculate IP, UDP, and TCP checksums. Corruptions include bit flip, bit transpose, and byte over-write
  • Supports 'WAN-Playback' allowing capture and replay
