%T Virtualized Cache Placement in an SDN/NFV Assisted SAND Architecture
%U https://discovery.ucl.ac.uk/id/eprint/10051477/
%X Web-caches play an important role in the architecture  of a Dynamic Adaptive Streaming over HTTP (DASH)  system, which can bring video files near to the clients. In such  systems, the placement of the caches affects the performance  of the video streaming applications. In this paper we select  the optimal network nodes for cache placement by taking into  account characteristics such as the bandwidth of the paths, the  places, and the number of the online clients, for a given network  graph. For this purpose, we use a placement algorithm which is  enhanced version of the Pressure algorithm proposed by Clegg  which we call PressureCache, in an implementation of virtualized  DASH Aware Network Elements (vDANEs). The results show  that the proposed approach gives better performance in terms  of received quality than random cache placement.
