Multicast and prefix caching are two promising approaches to provide scalable video-on-demand (VoD) services. We contribute to solve the adaptive multicast delivery and the cache allocation problem for VoD services with client caching under asynchronous client requests. We first propose a client caching enabled adaptive multicast delivery scheme, which combines the stream merginglike method with prefix...
The demands of video traffic transmission have grown rapidly in recent years. The emergence of converged network alleviates heavy burden on cellular network by introducing broadcasting. The transmission cost of contents with large demands can be effectively reduced. The content distribution strategy compromising between broadcasting and unicasting plays an important role in improving the performance...
The size and cascadability limits of nodes for Optical Burst Switching, caused by power losses, noise, and crosstalk, are analysed. We show that nodes with 32 fibres and 32 wavelengths per fibre are possible.
