IxLoad: IPTV and Video

IxLoad provides a comprehensive solution for testing IPTV and Video networks and services. IxLoad emulates millions of IPTV Broadcast Video and Video on Demand (VOD) subscribers to assess the true subscriber Quality of Experience (QoE).

 

IxLoad can be used to¹:

• Benchmark the performance of video servers
• Measure the channel change performance of an IPTV deployment
• Measure the ability of a transport network to carry video data in addition to data and voice. Measure the impact of network characteristics on video quality
• Stress test middleware devices such as encoder systems, digital media rights management (DRM) devices, billing systems, ad-insertion devices and conditional access systems
• Measure the perceived quality of the video delivered to the end-user
• Test performance of key IPTV infrastructure services like DHCP, DNS and AAA

Features and Specifications

Emulation

• Emulation of Broadcast IPTV and Video on Demand (VoD) IPTV subscribers
• Simulation of Microsoft TV clients and servers
• Microsoft TV servers including A, D and V-servers
• Support for ICC (Instant Channel change)
• Configurable D to A server stream switch behavior for MS TV clients
• Support for IPv4 using IGMPv1, IGMPv2 and IGMPv3
• Support for IPv6 using MLDv1 and MLDv2

Video codecs

• MPEG2, MPEG4, H.264 and others over MPEG2-TS streams
• MPEG4, H.264 and WM9
• Support for native MPEG4 transport of High definition streams
• Support for single-program (SPTS) and multi-program transport streams (MPTS)

Quality of Experience (QoE)

• Video quality metrics to measure both transmission quality using MDI and perceptual video quality using TVQM
• Video quality metrics on a per-subscriber basis
• Per video stream statistics such as jitter, latency, loss, bit rates
• MPEG level statistics on number of I, B and P frames received per video stream
• Support for jitter buffer emulation to model and characterize STB behavior

Real-world Testing

• Mix IPTV, voice and data traffic in the same test
• Support for RTP/UDP or UDP for video transmission
• Near wire-speed video transmission with very low jitter
• Channel change performance testing with Join and Leave latency measurements on a per-subscriber basis
• Support for interleaving multicast and VoD commands on client
• Support for user-specified video files or synthetic data using IxLoad servers
• Channel viewing sequences such as sequential, concurrent and random for user-realism
• Channel viewing profiles based on statistical distribution models for prime-time emulation
• Support for channel switch delay emulation
• Customizable client headers
• Configurable TOS and DSCP bit settings
