چکیده

For efficently caching mixed-media, this paper discusses several network-adaptive cache management schemes. Considering the characteristics of different types of media, we first proposed a multi-level page-size management scheme. Then, a media-characteristic-weighted replacement policy is presented to improve the hit ratio of mixed media including continuous and non-continuous media. Lastly, a network-conditionand media-quality-adaptive resource management mechanism is described to dynamically re-allocate cache resource for different types of media according to their request patterns. Simulation results demonstrate effectiveness of our propsoed approaches.

QoS-adaptive proxy caching for multimedia streaming over the Internet

This paper proposes a QoS-adaptive proxy-caching scheme for multimedia streaming over the Internet. Considering the heterogeneous network conditions and media characteristics, we present an end-to-end caching architecture for multimedia streaming. First, a media-characteristicweighted replacement policy is proposed to improve the cache hit ratio of mixed media including continuous and non-conti...

Adaptive per-user per-object cache consistency management for mobile data access in wireless mesh networks

We propose and analyze an adaptive per-user per-object cache consistency management (APPCCM) scheme for mobile data access in wireless mesh networks. APPCCM supports strong data consistency semantics through integrated cache consistency and mobility management. The objective of APPCCM is to minimize the overall network cost incurred due to data query/update processing, cache consistency managem...

Intelligent Buffer Cache Management in Multimedia Data Retrieval

In this paper, we present an intelligent buffer cache management algorithm in multimedia data retrieval called Adaptive Buffer cache Management (ABM). The proposed ABM scheme automatically detects the reference pattern of each file and intelligently switches between different buffer cache management schemes on per-file basis. According to our simulation based experiment, the ABM scheme yields b...

Client-Driven Joint Cache Management and Rate Adaptation for Dynamic Adaptive Streaming over HTTP

Due to the fact that proxy-driven proxy cache management and the client-driven streaming solution of Dynamic Adaptive Streaming over HTTP (DASH) are two independent processes, some difficulties and challenges arise in media data management at the proxy cache and rate adaptation at the DASH client.This paper presents a novel client-driven joint proxy cache management andDASH rate adaptationmetho...

ABM: Looping Reference-Aware Cache Management Scheme for Media-on-Demand Server

Legacy buffer cache management schemes for multimedia server are grounded at the assumption that the application sequentially accesses the multimedia file. However, user access pattern may not be sequential in some circumstances, for example, in distance learning application, where the user may exploit the VCR-like function(rewind and play) of the system and accesses the particular segments of ...
