RealNetworks this week plans to announce RealSystem iQ, an architecture for delivering streaming media to a variety of devices. RealSystem iQ, which will be deployed by content delivery network providers such as Akamai, Mirror Image, and Digital Island, consists of distributed, self-aware servers that can talk to each other to find the best path for sending media and to share information about network capacity or server outages. The system also lets content be injected into any point in the network, which improves reliability and scalability of media streams, RealNetworks officials said.
