Q1 2022
 

• Web Reduction in RAM and CPU usage (cross browser)
  
  
• Web Improvements of CDN offload on live content (Expect up to 5 points)
  
  
• Web Better trade-off between QoS and CDN offload

• Web Better monitoring of CDN requests: Full XHR response is now forwarded as data for non-successful queries to allow additional custom process
  
  
• Android iOS major release of native SDKs
  
  
  • Reduced footprint
    
            We have designed Mesh Delivery to be unintrusive and lightweight on user devices. Compared to devices not using Mesh:
    
    
    • Additional battery usage over 5 minutes: ~0.9%**
      
      
    • RAM usage: ~17 MB
      
      
    • Storage usage: total bundle 14-17 MB***, comparable to other native SDKs with similar source code size 
      
      Compared to previous versions of Mesh Delivery, this translates to 2x less average CPU use, 4x less average RAM usage, as well as low-end device hardware compatibility (e.g. 4 cores CPU, 1 GB RAM).
       
  • QoS and integration advantages
    
    This release also comes with other benefits, including:
    
    
    • Potential increase in CDN offload: +5-20%
      
      
    • Improved reaction to network speed changes
      
      
    • Smoother integration with ABR decisions
      
      
    • Easier SDK integration thanks to 10x fewer lines of source code (new integration requires just one class and ~30 SLOC)
      
      
    • Additional client-side debugging tools with real-time information like Mesh & CDN volume, offload, connected peers, peer-to-peer cache size, video latency, bandwidth, current video track, etc.
