VoIP/RTP Connections


VoIP Create/Modify Screen

  • Software Features
  • Hardware Features
SIP protocol used for call management.
  • SIP over UDP is supported on both Windows and Linux.
  • Can use directed mode, where VoIP phones call directly to themselves.
  • Can also use Gateway mode where the VoIP phones register with a SIP gateway.
  • SIP authentication is supported.
RTP protocol used for streaming media transport, and supports the following CODECS. More codecs may be supported in the future.
  • G.711u: 64 kbps data stream, 50 packets per second.
  • Speex: 16 kbps data stream, 50 packets per second, (Linux ONLY).
  • G.726-16: 16 kbps data stream, 50 packets per second.
  • G.726-24: 24 kbps data stream, 50 packets per second.
  • G.726-32: 32 kbps data stream, 50 packets per second.
  • G.726-40: 40 kbps data stream, 50 packets per second.
  • G.729a: 8 kbps data stream, 50 packets per second.
  • NONE: A messaging-only configuration is supported.
Supports PESQ automated voice quality testing.
RTCP protocol used for streaming media statistics (SIP only).
Each LANforge VoIP/RTP endpoint can play from a wav file and record to a separate wav file. Almost any sound file can be converted to the correct wav file format with tools bundled with LANforge. Sample voice files are included.
Current benchmarks show support for 280 or more emulated VoIP phones per high-end machine.
LANforge VoIP/RTP endpoints can call other LANforge endpoints or third party SIP phones like Cisco and Grandstream. Third party phones can also call LANforge endpoints and hear the WAV file being played.
Supports real-world protocols:
  • Layer 2: Raw-Ethernet.
  • 802.1Q VLANs.
  • PPPoE: Integrated PPPoE support.
  • Layer 3: IPv4, IPv6, UDP/IP, IGMP Multicast UDP, TCP/IP.
  • Layer 4: VOIP Call Generator (SIP, RTP, RTCP).
  • Layer 4: TELNET, PING, DNS, SMTP, NMAP (via add-on script).
  • File-IO: NFSv3, NFSv4, CIFS, iSCSI.
Supports up to 1000 concurrent TCP connections with base license package.
The CT505 is able to support 35 calls and 1Gbps or more of regular network traffic, depending on protocol mix and speed of the network under test. The portable chassis configurations may run at different speeds than the 1U rackmount systems.
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.
Mid-Range 1U rackmount server.
