The Virtual Stations may be configured with all of the virtual interfaces on the same subnet, or different subnets, depending on the testing requirements. When used with something like VoIP, it allows all of the VoIP calls to use the standard IP ports (with one call per virtual interface). The CT521-400 has one small and quiet fan and 6 antenna. It will fit into a small travel bag or briefcase for easy portability. No additional hardware or software is required, but it is suggested that you manage the system using the LANforge-GUI on a separate machine. The CT521-400 can also be managed over a serial console in text mode or through directly connected VGA monitor and keyboard.

Supports up to 1000 concurrent TCP connections with base license package.
The CT521-400 is able to push up to 345Mbps through an AP, depending on the protocols mix, wireless mode and environment, and speed of the network under test. Supports at least 20 VoIP (SIP, RTP) calls if appropriate licenses are purchased. More powerful systems are also available.
Supports real-world compliance with ARP protocol.
Supports ToS (QoS) settings for TCP/IP and UDP/IP connections.
Uses publicly available Linux, Windows and Solaris networking stack for increased standards compliance.
Utilizes libcurl for FTP, HTTP and HTTPS (SSL), TFTP and SCP protocols.
Supports file system test endpoints (NFS, CIFS, and iSCSI file systems, too!). File system mounts can use the virtual interface feature for advanced testing of file server applications.
Supports custom command-line programs, such as telnet, SMTP, and ping.
Comprehensive traffic reports include: Packet Transmit Rate, Packet Receive Rate, Packet Drop %, Transmit Bytes, Receive Bytes, Latency, Jitter, various Ethernet driver level counters, and much more.
Supports generation of reports that are ready to be imported into your favorite spread-sheet.
Allows packet sniffing and network protocol decoding with the integrated Wireshark protocol sniffer.
GUI runs as Java application on Linux, Solaris and Microsoft Operating Systems (among others).
GUI can run remotely, even over low-bandwidth links to accommodate the needs of the users.
Central management application can manage multiple units, tests, and testers simultaneously.
Includes easy built-in scripting for iterating through rates and packet sizes, with automated reporting. Also supports scriptable command line interface (telnet) which can be used to automate test scenarios. Perl libraries and example scripts are provided!
Automatic discovery of LANforge data generators simplifies configuration of LANforge test equipment.
LANforge traffic generation/management software is supported on Linux, Solaris and MS Windows.
