Triple Play Test Suite

Transcription

1 Triple Play Test Suite Triple Play is a general term referring to the delivery of Voice, Video, and Data services to an end-user as a unified service. From the end-user's perspective, triple play services are typically delivered as Voice over IP (VoIP), Video on Demand (VoD), and High Speed Internet (HSI) over DSL (Digital Subscriber Line) or Cable connections. IxAutomate s Triple Play test suite is designed to determine the performance characteristics of triple play access or backbone networks.

2 GUI Based Configuration Client traffic is emulated by selecting a DSLAM option or an ncpe option depending on whether you want aggregated versus individual client streams of traffic. xdsl subscribers are emulated with any mixture of internet, voice, and video traffic. QinQ, DHCP, PPP and DSCP service levels are supported with complete flexibility. On the server side the following emulations are supported: HSI (High Speed Internet)- Layer 2-3 stateless HTTP emulation, or Layer 4-7 stateful Premium, silver, or bronze marked HTTP traffic P/N: Rev A July Page 2 of 6

3 VoIP- Layer 2-3 basic stateless voice emulation, or Layer 4-7 stateful SIP call setup/teardown and voice emulation. Video- Layer 2-3 stateless IPTV-A, IPTV-D, or IPTV-V emulation, or Layer 4-7 stateful IPTV-AD or IPTV-V emulation Triple Play Suite Description Triple Play Tests: P/N: Rev A July Page 3 of 6

4 Scalability The Scalability test is designed to be a Proof of Concept test which varies the traffic and service (HSI, voice, video) characteristics from the starting values, during test interval 1, to the end values, during test interval N, to be able to find the limits of the network. There is an N+1 interval that uses the same traffic characteristics as interval 1, in order to test if the network recovers from possible overload conditions generated during the interval N. Results include: General- throughput, goodput, misdirected flows, delay, jitter, out of order packets HSI- HTTP requests successful and failed, latency, goodput VOIP- MOS scores, Jitter, successful versus failed calls, SIP Invite transaction failures Video- successful zapping rate, zapping failure rate, total zaps, simultaneous BTV viewers, channel switching latency, RTSP setup/play failures, Media Delay Index (MDI), Media Loss Rate (MLR) Video Statistics: P/N: Rev A July Page 4 of 6
