Reducing bandwidth usage of video traffic

Over-the-top video launches and campaigns can increase traffic and put bandwidth under pressure in a short period of time. In Australia, traffic volumes remained 25% higher 6 weeks after market introduction of Netflix. Network Operators need to be prepared for sudden spikes in their network utilization and be able to protect the quality of traffic for sensitive applications such as Voice over IP, to provide satisfactional quality for the majority of their customers.

Solution

Active traffic management reduces the average bit-rate used per video stream, only in areas where congestion occurs. This ensures that critical communications are secured and continue to function undisturbed - with minimal impact to the video quality. Customers may experience a quality degradation from 1080p to 720p during the time of congestion only.

Impact and Results

Good quality of experience is maintained for critical, sensitive services like VoIP, even under extreme data growth conditions, without significantly reducing the quality delivered to video consumers. This allows investments in network capacity to be delayed - and even OTT video prioritization packages to be created for those consumers requiring maximum video quality.
