 Our
patent-pending SmartCast technology combines innovative
multicast traffic handling techniques, smart QoS, and
application-aware traffic classification capabilities, for
top-quality Wi-Fi video transmissions. SmartCast
differentiates and manages multicast video frames separately
from all other traffic types, for robust wireless transport
for IPTV streams.
When SmartCast detects a wireless client subscribing to a
multicast streaming application, such as IPTV or a VOIP
call, it directs the associated multicast packets to each
subscriber, using the optimum data rate and signal path. To
ensure peak performance, all packets are queued/de-queued by
specialized schedulers, optimized for the corresponding
traffic type, the delay/jitter tolerance and bandwidth
requirements of the traffic, and the changing
characteristics of each station on the WLAN.
SmartCast features:
- Multimedia-optimized traffic management algorithms, which guarantee performance for multiple broadcast
quality voice or video streams, while maintaining adequate bandwidth for data applications
- Automatic classification of all traffic, based on UDP/TCP port and other application attributes, and
managed according to the traffic's classified priority and characteristics
- Automatic Type-of-Service (TOS) tagging, which eliminates complex QoS configurations, with automatic
management of lower-speed 802.11 devices, to assure bandwidth availability for prioritized video applications
- Four priority queues per station, for high prioritization granularity and precision for multiple concurrent
multicast streams
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.
