Joint Storage-Network Resource Management for Super High-Definition Video Delivery Service

A novel all-optical CDN network model based on mini-control plane for high-definition VoD service

“…Content delivery network has been accepted and widely studied as one of the methods that can be used to achieve higher user capabilities and lower network transmission cost in VoD network. To the best of our knowledge, most studies [2][3][4] concerning content delivery network focus on the strategic placement video content in distributed storage and some control and management strategies, very few consider that the network model for the dynamic interaction between storages which has became a potential issue for the High-Definition video and its increasing requirement. For example, not all the storage devices will have the same replica of large video file, so it will be inevitably occurred files exchanging between the storage as frequently as they need.…”

Towards large-capacity, energy-efficient, and sustainable communication networks

“…For the operation and management of DOPN, a new integrated resource management technology is necessary where not only the network resources (bandwidth) but also the storage resources (content) are comprehensively controlled. [12] The resource management system automatically selects the network to use according to the application. For example, the conventional IP router network can be used for the conventional service such as web or mail, while the DOPN can be used for a large-capacity service such as high definition video on demand (VOD) or teleconferencing (Fig.…”
