Internet2 Technology Evaluation Center Department of Telecommunications Texas A&M University, College Station, TX ADEC VoIP Beta Testing Contact: Walt Magnussen Tachyon Satellite Indoor UnitsLab Testing Setup Tachyon Satellite Antenna Graduate student Karthik Kannan places a call from the satellite phone to the local network phone. Packetized voice conversation travels to Tachyon indoor units. Packetized voice conversation is converted to an RF signal to be transmitted over the satellite antenna. Lab Implementation

37 37 VoIP Phone Codec Testing Internet2 Technology Evaluation Center Department of Telecommunications Texas A&M University, College Station, TX Contact: Walt Magnussen Goals and Objectives Evaluate various VoIP codecs Compare various vendor implementations of the codecs Research Codec Testing Algorithms

38 38 VoIP Phone Codec Testing Internet2 Technology Evaluation Center Department of Telecommunications Texas A&M University, College Station, TX Contact: Walt Magnussen Ixia traffic generator loads one side of the network with generic TCP traffic. Call is placed from one IP phone to the other. Anritsu Data Quality Analyzer measures packet loss between the two phones. Agilent VQT transmits audio file though one IP phone and receives the audio file with potential missing packets though the other IP phone. VQT then compares the two audio files and returns a call quality score (MOS). Network Lab Setup Above: Graduate students Clark Xu Yang and Karthik Kannan analyze results from voice quality test. Design and Implementation Network Diagram

39 39 VoIP Phone Codec Testing Internet2 Technology Evaluation Center Department of Telecommunications Texas A&M University, College Station, TX Contact: Walt Magnussen Results and Conclusions G.711 codec provided acceptable audio quality (MOS >3.0) up to 5% packet loss. GIPS codec significantly outperformed G.711 before declining in audio quality at 15%packet loss. G.729 codec degraded at a faster rate when packet loss exceeded 5% Higher bandwidth applications such as LANs or MANs should use G.711 as default
