CANDELA社10/100/1000Mbps対応ネットワーク・エミュレータ “ LANforge-ICE ”

L4-L7トラフィックテスタ の視点ではなく、ネットワークエミュレータの視点での、障害の再現になります。
Candela Technologies suggests NetEqualizer for automated traffic shaping applications.

◆ LANforge ICEcap Network Probe Feature Highlights

The LANforge-ICEcap tool can probe a network and
save the probed latency, packet loss and other values to an XML file that can be replayed by
the LANforge-ICE WAN emulator.
This allows for realistic WAN emulations based on real-world networks.

◆ 添付ソフトウェア ICECap を利用して、実環境のネットワーク特性を記録し、LANforge-ICEでネットワーク挙動の動作再現が可能。

無料のICEcapソフトを使って、実際の障害網をキャプチャして、LANforge-ICEに読み込ませて再現が可能です。
「ICEcap (添付SW)を利用して、Windows/LinuxPC からIPアドレスを指定し、擬似Pingデータ送受からネットワークの遅延/パケットロス/伝送帯域の状態を時系列データとして、XML形式のプロファイルとして保存可能。
このXMLファイルに基づき、LANforge-ICE で状況の再現が行なえます」

◆ LANforge Netsmith: Virtual Network Builder

2ポート以上の複数ポートを接続可能ですので、バーチャルルータのように複数IP網を擬似できます。

• Supports Packet corruptions, including bit-flips, bit-transposes and byte-overwrites.
• Supports WanPath feature to allow configuration of specific behavior between different IP subnets, MAC addresses or other packet filters using a single pair of physical interfaces. WanPath support may require purchase of additional WanPath licenses, please ask your sales contact for more information.
• Supports routed and bridged mode for more flexibility in how your configure your network and LANforge-ICE.
• 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 free 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.
• Includes easy built-in scripting to automatically iterate through bandwidth, latency and other settings. Advanced programatic scripting over a tcp socket also supported and example perl libraries and scripts are included.
