Telnet Networks Inc. - Candela Technologies LANforge Fire Network Traffic Generation

LANforge Fire Traffic Generator

Network traffic on business networks includes multi-tier applications, user loads from the web, e-mail, web conferencing, streaming media and VoIP. Network devices such as switches or routers are called upon to support increasing traffic with a wide array of protocols, packet sizes, addresses, traffic patterns, VLAN segmentation and QOS. LANforge Fire provides a test solution to generate traffic to validate that the devices will be able to perform when making configuration changes, adding users or applications.

LANforge Fire - The Business Case

Validates stability and data throughput on devices under evaluation.
Useful for testing any network - Ethernet, Wireless and VoIP
Cost effective solution for testing efforts requiring many data-generating ports or simulation of multiple mIP's and protocols.
Turn key solution. The LANforge systems can come pre-installed and configured to customer requirements.
Modular architecture allows you to leverage existing LANforge investment as your need for capacity increases.
Ease of use - Manage entire LANforge installation through one interface, from anywhere on the network.

LANforge VoIP/RTP Call Generator Feature Highlights

SIP and/or H.323 protocol used for call management.
- SIP and H.323 are now supported on both Windows and Linux.
- SIP/UDP supported, H.323 uses both UDP and TCP.
- Can use directed mode, where VoIP phones call directly to themselves.
- Can also use Gateway mode where the VoIP phones register with a SIP or H.323 gateway.
- SIP authentication is supported.
RTP protocol used for streaming media transport, and supports the following CODECS. More codecs will be supported in the future.
- G.711u: 64kbps data stream, 50 packets per second (SIP, H.323)
- Speex: 16kbps data stream, 50 packets per second (SIP on Linux ONLY)
- G.726-16: 16kbps data stream, 50 packets per second (SIP ONLY)
- G.726-24: 24kbps data stream, 50 packets per second (SIP ONLY)
- G.726-32: 32kbps data stream, 50 packets per second (SIP ONLY)
- G.726-40: 40kbps data stream, 50 packets per second (SIP ONLY)
- G.729a: 8kbps data stream, 50 packets per second (SIP ONLY)
- NONE: A messaging-only configuration is now supported (SIP ONLY)
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 140 or more emulated VoIP phones per machine.
LANforge VoIP/RTP endpoints can call other LANforge endpoints or third party SIP or H.323 phones like Cisco and Grandstream. Third party phones can also call LANforge endpoints and hear the WAV file being played.
