PeerNet helps broadband operators to minimize network traffic by making better use of the existing infrastructure. Large and popular content files are temporarily stored and distributed from local P2P-caches in the access networks, reducing peak traffic loads on weak links further up in the network. Product features: Content type agnostic. Dynamic traffic detection; Caching content with largest network traffic impact. Fault tolerant: P2P caching nodes can fail without damaging QoS. Cost efficient: Caching on inexpensive consumer grade hardware. Diagram 2. Decrease in link load from using locality aware P2P. (Source: H. Xie, A.
