- question: How does Delivery Optimization deal with congestion on the router from peer-to-peer activity on the LAN?
answer: |
Starting in Windows 10, version 1903, Delivery Optimization uses LEDBAT (server-side LEDBAT) and rLEDBAT (receiver-side LEDBAT) to relieve such congestion. In Delivery Optimization, LEDBAT is specifically used for P2P connections, while rLEDBAT is utilized for HTTP and Connected Cache connections, particularly for background downloads.
