such as Protocol Independent Multicast can be used to deliver stream content to multiple Local Area Network segments. Peer-to-peer (P2P) protocols arrange for prerecorded streams to be sent between computers. This prevents the server and its network connections from becoming a bottleneck. However, it raises technical, performance, security, quality, and business issues.
