Smart Multi-CDN Switching for Video Streaming
NPAW’s CDN Balancer helps streaming services improve QoE and optimize their video delivery, automatically selecting the best CDN based on perceived quality and business needs
What is smart multi-CDN switching?
NPAW’s CDN Balancer is a smart multi-CDN switching and monitoring tool built for video streaming. It tracks CDN performance in real- time at the end-user level to choose the optimal CDN to deliver a smooth viewing experience and meet your needs. CDN Balancer can select the best CDN at the start of the stream or change CDNs mid-stream to avoid outages and prioritize quality or business goals.
Improve Quality of Experience and Service
Ensure a seamless streaming experience by minimizing buffering and video start issues, switching to the CDN offering the best quality and lowest latency for each user
Adapt video delivery to your business needs
Identify the best M-CDN strategy for your business goals and easily define custom decision-making progress by setting up security, business, and performance rules
Optimize delivery for costs while protecting quality
Leverage cost-effective CDN providers without risking service quality or availability. Use the most cost-effective CDN while it ensures your target video quality: if it goes below your goal, automatically switch to other CDNs.
Active mid-stream CDN switching
Take your QoE to the next level by automatically selecting the best-performing CDN for every chunk of video
Automated chunk-level CDN selection
Download in parallel video chunks from different CDNs, with real-time and bidirectional communication between the client-side plugin and the server-side platform
CDN Balancer not only helps us tailor our CDN consumption to each of our audience segments’ needs, but it also lets us control costs and allocate our infrastructure resources in a way that’s not only beneficial for us, but gives our end users a better streaming experience.
