Transparent Video Caching Reduces the Overwhelming Growth in DSL Network Traffic
Network operators are being forced to add capacity to meet the tremendous growth in network demand from video services (e.g. YouTube), file sharing, and software updates. Josh Adelson of Peerapp explained to me at the TelcoTV trade show that inserting smart video storage and distribution services (transparent caching) into DSL networks can dramatically reduce the capacity needs on the network. Without video caching, network operators will have excessive cost and complexity of adding capacity or provide a poor quality of service resulting in higher support costs or customer churn. The solution is to add transparent caching servers that can automatically identify and store popular video content. Transparent caching helps to reduce network capacity load, minimizes the capacity need (and cost) for Internet transit links, and increases customer satisfaction (higher video quality levels). Transparent caching automatically identifies popular content and stores the content as close to the subscriber as possible. The PeerApp Ultraband Transparent cache can be inserted almost anywhere within the IP portion of a DSL network. When caches are placed close to the edge, the network capacity savings increases because the transport is reduced over larger parts of the network. Transparent caching is simple to install and additional caching servers can be installed as the need increases (easily scalable).
