SmartCast Ensures Highest Video Quality, Enables Wireless IPTV
Ruckus patent-pending SmartCast technology combines innovative multicast traffic handling techniques, smart QoS and
application-aware traffic classification capabilities to ensure the highest quality video transmissions over Wi-Fi.
SmartCast differentiates and manages multicast video frames separately from all other traffic types to provide a robust
wireless transport for IPTV streams from the broadband gateway to the set-top-box. SmartCast detects a receiver tuning to
an IPTV channel and then directs the associated multicast video packets to each receiver using the optimum data rate and
signal path for that receiver. This ensures optimum performance while enabling reliable delivery of IPTV packets.
Multimedia optimized traffic management algorithms guarantee performance for multiple broadcast quality video streams
while maintaining adequate bandwidth for data applications. SmartCast automatically classifies all traffic based on
UDP/TCP port and other application attributes, and manages each traffic type (voice, video, data) according to its classified
priority and characteristics. Automatic Type-of-Service (TOS) tagging eliminates complex QoS configurations, while
automatic management of lower-speed 802.11b devices assures bandwidth availability for prioritized video applications.
Four priority queues per-station result in high prioritization granularity and precision for multiple concurrent video streams.
All packets are queued/de-queued by specialized schedulers optimized for the corresponding traffic type. Each scheduler
takes into account the delay/jitter tolerance and bandwidth requirements of the traffic and the changing performance
characteristics of each station on the WLAN to ensure the best end-user experience.
