autoVoIP™ Traffic Simulator

autoVoIP™Traffic Simulator provides an unrivaled tool to simulate traffic and stress test the limits on all types of VoIP networks.

The advanced technology helps for example a consultant or an organization to prevent unnecessary project delays and future maintenance costs, as well as customer or client dissatisfaction.

autoVoIP™Traffic Simulator can be used pre- and post deployment with any type of VoIP network.

autoVoIP™ Traffic Simulator measures the QoS achievable over time at different points on the network by simulating traffic.

In addition, Traffic Blaster stress tests the network to identify network limits by monitoring the impact on the QoS as it gradually increases the loading of VoIP and non VoIP Traffic.

The unique Pre Deployment Report provides a Microsoft® Word document that automatically includes the test results, making recommendations on phone limits and showing the impact of using different Codecs.

autoVoIP™ Report Browser supplies valuable SLA information, reporting on the QoS and historical data.

autoVoIP™ Traffic Simulator is easy to install and deploy. Users need only purchase licenses for the autoVoIP™ Traffic Simulator Host PC as free software is provided for the remote ends of the link that can be downloaded and installed on local PCs, the free Sink system and the Traffic Blaster target system.The free software can be installed on lower specified PC Platforms, making it more cost effective to deploy.

The free Sink system can be installed on lower specified PC Platforms, making it more cost effective to deploy.

By using Traffic Blasters in multiple autoVoIP™ Traffic Simulators, system fully shows the impact of adding groups of phones for example at different points on the network.

Since autoVoIP™ Traffic Simulator has the capability to re-size screen formats, users can continue to use their existing equipment.

autoVoIP™ Traffic Simulator is created with the trademarks of Codima Toolbox, easy-to-use, cost efficient and highly visual.

• This is a true simulator using real RTP frames, sent at standard frame rates over UDP with RTP ports. That ensures the QoS engineering in the network will treat the stream the same as normal VoIP Traffic - a more effective approach for checking QoS than using for example an ICMP Pinger.
• Easy to install and deploy - free downloads of remote end software for autoVoIP™ Traffic Simulator Sink system and the Traffic Blaster target system on local PCs
• autoVoIP™ Report Browser produces reports in htm format covering the simulations, they are automatically created daily, weekly and monthly and can be customized to local languages and include company logos.
• The Pre-Deployment Test Report provides results on what the phone limits are and what the impact would be when using different Codecs

• Prevents unnecessary project delays
• Prevents future maintenance costs, keeping IT budgets on schedule
• Prevents customer or client dissatisfaction with the start up of the VoIP network

• A minimum of three Host PCs are needed:

One to run the Traffic Simulator
One to respond to the traffic, i.e., send back RTCP reports on the received traffic
One to be the target for Traffic Blaster

• The autoVoIP™ Traffic Simulator Sink system reports back using RTCP, in the same way a phone would. This method allows autoVoIp™ Traffic Simulator (and if required a third party) to measure jitter and frame loss
• Access Automated Correlation Engine (ACE) via the History Chart to find root causes
• Access report facility via the History Chart
• Multiple simulators may be defined to check multiple paths, such as remote sites on an occasional or continuous basis
• Can simulate multiple Codecs from one generator test stream
• Supports a number of Codecs, including:
• PCMu
• PCMa
• G723-8k
• G726-16
• G728
• G729 - 8k
• Build traffic simulators - view the results associated with running the simulators
• Simulators provide user control of :
• Target address
• Priority (DiffServ)
• Simulated phone jitter buffer
• Codec used in statistics calculation show the impact on QoS when the Codec is changed

• Three Host PCs to provide platforms for :
• One PC used to run autoVoIP™ Traffic Simulator
• Processor: 2 GHz or faster


• Memory: 1Gb minimum


• Operating System: Microsoft Windows XP Professional, Microsoft 2003 Server or Windows Vista


• Disk space: 30 Gb for live system


• Monitor resolution: 1240 x 1024 (minimum)



Two PCs for the remote ends of the links
- one for Simulator and one for Traffic Blaster

• Processor: 1 GHz


• Memory: 512 mb RAM


• Operating System: Microsoft Windows XP Professional, Microsoft 2003 Server or Windows Vista


• Monitor resolution: 1280 x 1024 (recommended), 1240 x 768 (minimum)

• Can be used to measure the effect of adding more phones to an existing VoIP system


• Multiple Traffic Simulators/Traffic Blaster systems can be used to emulate groups of phones at different locations on the network and monitor the QoS


• QoS is measured in parallel for all simulation sites on the network giving a true indication of the behavior of the whole phone deployment

• Quality of Service (QoS) analysis - at a glance, see if VoIP is within safe limits, marginal or likely to be seriously degraded (6 color bands used)


• Sends out competitive traffic and non competitive traffic - to see what the QoS would be for a single user when different levels of VoIP and non VoIP traffic are present


• Safety facility, to ensure it does not send traffic out indefinitely - runs for 8 hours unmanned, stops and can be restarted manually, locally or remotely, for another 8 hours run


• Distributed loading can be used to match the exact phone deployment together with independent QoS monitoring at each deployment cluster site


• Automatically explores the limits of the network, using autoCheck Mode it shows the QoS degradation as traffic patterns are automatically explored


• Automatically checks the QoS engineering using a sophisticated load generation algorithm


• Load specified by phone/codec using easy to understand phone counts


• Supports a number of Codecs, including:


• G711 - 64k
• G723 - 6.3k
• G729 - 8k

Additional ones can be added
• Traffic loading may also be specified as bandwidth or frame loading


• The Automated Correlation Engine (ACE) provides an expert system to analyze the QoS graphs


• Results can be exported to HTML Reports and to the Microsoft® Word Pre- Deployment Test Report.
