“…The Rayleigh distribution as defined earlier is related to the exponential distribution so that if Y is exponential with parameter λ, then X = √ Y σλ is Rayleigh with parameter σ. Thus, utilizing (14) and the fact that F (ax 2 ) = 2axf (ax 2 ), we have…”

“…The energy-efficiency of caching placement has been optimized in [13]. Optimal cache sizing has been studied for Peer-to-Peer (P2P) systems with realistic bandwidth and cache storage costs (see, e.g., [14]). Recently, in [15], the authors find the required cache size in backhaul-limited wireless networks, while [16] employs a scheme where the caching probability increases proportionally with file size.…”

Given a statistical model for the request frequencies and sizes of data objects in a caching system, we derive the probability density of the size of the file that accounts for the largest amount of data traffic. This is equivalent to finding the required size of the cache for a caching placement that maximizes the expected byte hit ratio for given file size and popularity distributions. The file that maximizes the expected byte hit ratio is the file for which the product of its size and popularity is the highest -thus, it is the file that incurs the greatest load on the network. We generalize this theoretical problem to cover factors and addends of arbitrary order statistics for given parent distributions. Further, we study the asymptotic behavior of these distributions. We give several factor and addend densities of widely-used distributions, and verify our results by extensive computer simulations.

“…Establishing content distribution structure based on point-to-multipoint and bypassing redundant point-topoint traffics is a feasible solution to provide high quality multimedia service [6] . Based on above principle of proximity deployment with large-scale content distribution, new technologies and equipments have emerged in recent years such as Peer-to-Peer (P2P) distribution [7] , Content Distribution Cloud [8] , Access converging router (ACR) [9] , P2Pcache [10] , iIPTV [11] and so on.

This paper addresses a key challenge in the design and implementation of multimedia distribution systems so that users can experience good performance with minimal operational costs. In current structures, the conflict between network architectures and service provision causes a decline in users' expectations of quality. Network reconfiguration provides a feasible solution for dynamic distribution as a primitive for both quality and efficiency. In this paper, we first present a scheme for a layer-based hybrid multimedia distribution system LHMDS, and then introduce a dynamic sliding push-delivery mechanism based on reconfiguration of the distribution of hotspot files. The LHMDS adopts a unique structure with hybrid channels, including broadcast and unicast ones, and adjusts its distribution topology according to the congestion status, thereby pushing hotspot files dynamically. The mechanism dynamically pushes files to upper or lower network layers depending on the network status while distributing hotspot files by broadcast channels and other files by unicast ones. This guarantees service quality as well as improving resource utilization. Finally, we validate the feasibility and performance of the scheme through a simulation.
