DATA SHEETIxLoad TM HTTP Live Streaming (HLS)Player Client EmulationHTTP Live Streaming (HLS) is a media streaming specification developed byApple®, which uses HTTP as the transport protocol. The streamingtechnology works for on-demand streaming as well as live streaming. TheHLS specification is documented in the following draft RFC: draft-pantoshttp-live-streaming-04,available at http://tools.ietf.org/html/draft-pantos-httplive-streaming-04.IxLoad emulates essential HLS® media player capabilities, allowing thecreation of thousands of interactive on-demand and live streaming usersessions for realistic load testing of HLS compatible media platforms anddelivery architectures.The HLS Player emulationoffers:• High performance clientemulation to scale andemulate behavior ofthousands of iOS baseddevices• Dynamic parsing of static,secondary and dynamicPlaylist files• Support for playback of ondemandand live mediastreams• Full support to follow HTTPredirection to receive contentfrom streamers and originservers• Adaptive algorithm modelsupshifts and downshiftsbased on network conditions• Real-time assessment ofquality levels duringplayback• Buffer configuration inseconds and fragmentrequests to fill the buffer• HTTP proxy support to testcontent cache systemsHLS MediaServerHTTPIxLoad HLS PlayersProxyDistributionOriginFigure 1: Delivering media with HTTP Live Streaming (HLS) Technology26601 Agoura Road | Calabasas, CA 91302 USA | Tel + 1-818-871-1800 | | www.ixiacom.comDocument No.: 915-1781-01 Rev C December 2013 - Page 1

DATA SHEETThe HLS Player emulation can be used to:• Use in conjunction with HLS compatible media servers, content replication, and proxy devices, and contentload balancers.• Create large-scale HLS Player user sessions for load testing of devices and networks in order to measurethroughput capacity with reliable delivery of streams.• Emulate adaptive streaming behavior that dynamically up-shifts or down-shifts the media stream in order todeterministically playback streams of different quality.• Determine the optimal user session limits of edge and origin media servers, content proxy, caching systems,and media load balancers.• Determine the total number of streams a content delivery network (CDN) can handle with consistent andreliable stream deliveryHLS Player Emulation FeaturesIP SupportEmulationInteroperabilityStream HandlingUser PlaybackFile playbackCommandConfigurationMedia NameBufferPerformanceMetricsIPv4HLS Basic Media Player functionalityAll messages sent over HTTPWowza Media Server 3.0 and other HLS compatible media delivery platformsPlayback of recorded and live streamsPLAYAny media delivered using HLS technologyDestination Server: IP:PORT, FQDN, HostnamePlay Duration: Automatic (until end), or user configurable rangeConfigurable on a per playback command basisConfigurable on a per HLS emulation basis, in seconds• Active stream count• Throughput (RX, TX)• HTTP connection and transaction level statistics• HTTP Error Response tracking (e.g. 404, 503)• Playlist Requests• Segment for Audio and Video Requests• Bit-rate Shift RequestsObjectives • Total user sessionsPage 2
