  1. PESQ|Server

  2. Who is Nextragen? • Provider of software-based measurement solutions to test and ensure the quality of Next Generation Networks • VoIP • Video • IPTV • Modular portfolio • Continuous and flexible end-to-end quality testing in networks • Testing, Monitoring and Analysing the network quality from the • technician's point of view − Quality of Service (QoS) • user‘s point of view − Quality of Experience (QoE) • 100 per cent“Made in Germany“ • Global sales through a network of certified partners

  3. NEXTRAGEN Solutions Secure NGN Investments! Monitoring Testing Analysing • Monitoring of NGN infrastructures for constant testing, reporting and securing of SLA quality • Proactive detection and notification of network errors • Active alert in case of network problems to avoid failures at user level • Readiness checks to prepare and secure investments into NGN • Testing and analysis ofNGN infrastructures after implementation • Quick analysis of errors und quality shortcomings during operation • Precise identification and localisation of network problems • Immediate restoration of QoS Avoid follow-up costs Plan and secure network quality Secure network performance

  4. PESQ|Server – Active Traffic Emulation in NGN and VoIP PESQ|Server runs PESQ-based measurements during field service using • Nextragen’s eVT • hand-held testers (certified by Nextragen) PESQ|Server tests and analyses the end-to-end voice quality of • hybrid VoIP infrastructures • NGN connections

  5. PESQ|Server – Next Generation Network Test Solution • PESQ│Server provides valuable insights into the network capacity of existing networks • Software licences are provided centrally via the PESQ│Server. All devices connected to the network under test run on the same license. • PESQ-based measurements using eVT or hand-held testers certified by Nextragen • Remote station for end-to-end voice quality testing via PESQ • Easy and intuitive user interface • Storage, documentation and reporting of all measured connections

  6. PESQ|Server – Visibility into Network Performance Optimization • PESQ│Server stores, documents and illustrates all test results using • Tables • Graphics • Evaluation of RTP sessions via R-factor/MOS in accordance with the E-model (ITU-T Rec. G.107) • Testing of network performance based on PESQ (ITU-T Rec. P.862) • PESQ│Server sends PESQ values directly to the testing device. All information is mirrored back to the centralised PESQ│Server for support, planning and analysis. • PESQ│Server’sReportingTool • Output of measuring results in PDF • Creating of user-specific reports • Technical data • Service-related data for the management

  7. PESQ|Server Features VoIP codecs • G.711 a-/µ-law • G.721 • G.723.1 • G.726 16/24/32/40 • G.729a • GSM • iLBC Measured network parameter • DeltaT (min/avg/max) • Jitter (min/avg/max) • Packetloss • Delay Evaluation models • E-model (ITU-T Rec. G.107) • R-factor / MOS-CQE • PESQ (ITU-T Rec. P.862)* • PESQ / MOS-LQO VoIP protocols • RTP • RTCP • SIP • SDP • STUN Static jitter buffer * Optional in connection with PESQ|Server

  8. PESQ|Server in a Nutshell • Centralised PESQ-lisence via the PESQ|Server • Individual testing devices (eVT or hand-held tester) use centrally provided licence • Possible to use alternative testing devices for end-to-end voice-quality testing of network connections PESQ|Server is ideal to control and remotely manage Nextragen’s eVT or hand-held testers including configuration, monitoring, data collection, processing test results and report generation
