LANforge VoIP/RTP Call Generator Feature Highlights


  • SIP protocol used for call management.
  • SIP/UDP supported.
  • 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: 64kbps data stream, 50 packets per second (SIP, H.323)
    • G.729a: 8kbps data stream, 50 packets per second (SIP ONLY)
    • Speex: 16kbps data stream, 50 packets per second (SIP on Linux ONLY)

LANforge WiFIRE 802.11a/b/g/n/AC Stateful Traffic Generator


  • Useful for testing Wireless Access Points and deployments.
  • Can emulate up to 200 802.11a/b/g/n wireless client stations (Virtual STAs) per a/b/g/n radio, and up to 64 per /a/b/g/n/AC radio.
  • Each radio can run on only a single frequency at a time. So, all stations on a radio must be able to connect to an AP on the same channel.
  • Each Virtual STA can be associated with a particular Access Point (AP).
  • Each Virtual STA can be set to a specific protocol (/a, /b, /g, /n, /AC) or be told to use the best option available.
  • For 802.11n and AC, HT-40 can be disabled.
  • For all protocols, the rates can be specified or left auto.
  • AMPDU density and factor can be modified for 802.11n stations.
  • Each Virtual STA has unique MAC address, IP address and routing table.
  • 128bit WEP, WPA, WPA2 (PSK) and related wpa_supplicant authentication methods supported.
  • Advanced authentication support includes: 802.1x, 802.11u, HotSpot 2.0/HS2.0, EAP-TLS, EAP-TTLS with MSCHAPv2, EAP-SIM, EAP-AKA, etc.
  • Automated captive portal login support for Virtual STAs.
  • Supported standards include: 802.11r (OTA and over DS), 802.11w
  • Supports all LANforge FIRE stateful traffic generation features, including HTTP, TCP, UDP, TCPv6, UDPv6, VOIP (SIP, RTP) * and more.
  • Supports bridge mode where wired Ethernet traffic can connect to the wired port on the LANforge an have their traffic sent onto the wireless network. This allows third-party traffic generators to be used. Each MAC address is associated with a single WiFi station in LANforge. With release 5.2.2, traffic can be bridged by IP address as well.


LANforge NetReplay & Backtrack Feature Highlights
