autoVoIP™ Simulator

Used essentially post deployment, the VoIP monitoring tool tracks the QoS 24/7 week in week out. This identifies time-based variations in the VoIP QoS as well as ensures that suitable Codec are used.

autoVoIP™ Simulator can be used with any type of VoIP network to measure QoS over time at user selected key points on the network by simulating synthetic phone traffic.

A true VoIP simulator, using real RTP frames, autoVoIP™ Simulator uses identical frames and sends them consistently at same frame rate.

autoVoIP™ Simulator focuses on monitoring QoS between two points on the network, simulating the media (RTP) and reporting on QoS using RTCP signaling, hence it can be used on all types of VoIP networks to provide a 24/7 analysis of the actual QoS achieved.

autoVoIP™ Simulator can be used to monitor QoS in situations where the phones may not be in use or where the Phones are not capable of providing QoS.

The VoIP testing tool is easy to install and deploy. A Simulator Host PC and Simulator Sink PC are needed.

A single Simulator Host PC and multiple free Simulator Sink systems can be deployed to monitor the QoS for several paths on the network simultaneously.

Codima offers free downloadable software for the Simulator Sink PC that can be installed on lower specified PC Platforms, making it more cost effective to deploy.

An empowering function is the web based Report Browser that supplies valuable SLA information. It provides History charts/HTML Reports covering QoS, percentage of lost frames and jitter and automatically creates daily, weekly and monthly reports covering the simulation results.

autoVoIP™ Simulator can be deployed as a standalone or the Simulator Host can be integrated with other tools from Codima Toolbox

• Use of real RTP frames when running the Simulation function, sent at a standard frame rates over UDP using RTP ports. This ensures that 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 enables users to deploy as many Simulator Sink Systems as needed
• QoS is measured in parallel for all simulation sites on the network giving a true indication of the behavior of the whole phone deployment
• The web based Report Browser providing access to automatically created daily, weekly and monthly reports covering the Simulation results - customizable for local languages and display of company logos

• Provides value for money - Quality of Service assurance 24/7
• Prevents customer or client dissatisfaction
• Prevents unnecessary project delays
• Provides QoS analysis at a glance, user can see if VoIP is within safe limits, marginal or likely to be seriously degraded when loading increases (6 color bands used)

• A Simulator Organizer used to build Simulators, which create a stream of RTP frames addressed to a Simulator Sink system, and display the QoS achieved between the two points on the network. Simulators give the user control of:
• Target address
• Priority (DiffServ)
• UDP Port
• Simulated phone jitter buffer
• Simulator Sink systems - free software for installation at the destination address (remote end). Sink Systems reports back using RTCP, in the same way a phone would. This method allows the autoVoIP™ Simulator (and if required a third party) to measure jitter and frame loss
• Simultaneous Simulations - a single autoVoIP™ Simulator can be used to build multiple Simulators, providing a central point to monitor QoS simultaneously for multiple paths through the network on an occasional or continuous basis
• Codec comparisons - shows what the QoS would have been if different Codecs has been used in the simulation. Codecs supported include:
• PG711 PCMu
• G711 PCMa
• G723 - 8k
• GG726 -16
• G728
• G729 - 8k
• History graphs - displays the long term QoS statistics for each simulation
• Automated Correlation Engine (ACE) analysis of History graphs - finds root causes
• Reporting facilities include
• Quick reports generated from the History graphs associated with the simulations
• The web based Report Browser used to review long term reports covering simulations

• A minimum of two PC platforms are required to operate autoVoIP™ Simulator:
• Host PC used to send out RTP frames based on user input to the Sink PCs IP address
• Processor : 2 GHz or faster
• Memory: Minimum 1Gb
• Graphics Card: Minimum 16Mb
• Operating System: Microsoft® Windows XP, Windows Server 2003, Windows Vista or Windows 7
• Screen resolution: 1280x1024 (recommended), 1024 x768 (minimum)
• Basic Sink PC the remote end used to respond, i.e., send back RTCP reports to the Host PC:
• Processor : 1 GHz or faster
• Memory: Minimum 512Mb
• Graphics Card: Minimum 16Mb
• Operating System: Microsoft® Windows XP, Windows Server 2003, Windows Vista or Windows 7

• Add Pre Assessment Stress Testing to stress test any VoIP network - identify the phone loading levels where QoS is not acceptable
