Exponential growth of video traffic challenges the current paradigm to stream large amounts of video contents to end users. Cloud computing with elastic resource allocation supported enables cost-effective video streaming with desired QoE requirements. We abstract a new theoretical model from real systems for elastic media streaming by introducing a virtual content service provider that rents c...

Virtual maintenance has emerged as one such technology which has attained maturity and gained acceptance in industry. The key contribution of virtual maintenance is to reduce the design cost and cycle. Currently, virtual maintenance verification focuses on these statically qualitative contents, and there is a big gap between virtual maintenance simulation time and actual maintenance time. This ...

Virtual Trees are source-rooted trees in ATM networks in which VCs originating at the source but going to diierent destinations can share some of the bandwidth pre-allocated to the VT, thus providing an additional multiplexing advantage over Virtual Paths. Non-ATM protocols such as MIL-STD-188-220A can also take advantage of Virtual Trees because source concatenation provides a beneet very simi...
