Multicast Streaming
Multicast streaming is a network transmission method that delivers data, such as video or audio, from a single source to a selected group of recipients efficiently, rather than to everyone or just one. This approach minimizes bandwidth usage by sending one stream that multiple devices can tap into, making it ideal for applications like live webinars or online gaming where scalability is key.
Did you know?
Multicast streaming can reduce network traffic by up to 95% compared to traditional unicast methods during large-scale events, as demonstrated in the 2012 London Olympics where it helped stream live feeds to millions without crashing the infrastructure. This efficiency has also enabled cost-effective delivery of educational content, like massive open online courses (MOOCs) that reach thousands of students simultaneously.
