The present work briefly introduces media format interchange and proceed to explain the media-aware network enabled by 3D Streaming and Intelligent Buffering. Section 2 presents current bandwidth challenges to immersive media streaming to a host of different immersive platforms of varying screen sizes. Section 3 explains the 3D Streaming network architecture and Intelligent Buffering over a 10G network, along with a heuristic implementation of asset scheduling contained within the client-side logic. Section 4 evaluates bandwidth usage savings of queue-forming traffic flows of vectorized asset streaming over non-queue forming streaming of rendered frames. Latency measurements on the client-side demonstrate asset scheduling effectiveness in gaining maximum concurrency while fetching assets from remote asset servers. The conclusive sections describe algorithmic improvements made to asset scheduling and integration of current 10G capabilities into the existing network architecture.
