In mobile environment, enhancing data consistency among data caches by mobile clients and data residing in a server is a big problem due to the mobility of nodes. Many updating schemes have been proposed to solve this problem. However, these updating schemes produce a high updating cost which consumes most of the limited resources of mobile clients as battery power. In this paper, to solve this...

Cache depot is a performance enhancement technique on cache-coherent non-uniform memory access (CCNUMA) multiprocessors, in which nodes in the system store extra memory blocks on behalf of other nodes. In this way, memory requests from a node can be satisfied by nearby depot nodes without going all the way to the home node. This not only reduces memory access latency and network traffic, but al...

Patching and transition patching are two techniques proposed to build efficient video-on-demand (VoD) systems. Patching works by allowing a client to playback video data from a patching stream while caching video data from another multicast video stream for later playback. The patching stream can be released once video playback reaches the point where the cached data begins, and playback contin...

This paper is the first analysis of caching architectures for Question Answering (QA). We introduce the novel concept of multi-layer collaborative caches, where: (a) each resource intensive QA component is allocated a distinct segment of the cache, and (b) the overall cache is transparently spread across all nodes of the distributed system. We empirically analyze the proposed architecture using...

Today, the internet requires many additional mechanisms or protocols to support various ever-growing applications. As a future architecture candidate, Named Data Network (NDN) offers solution that naturally fulfills this need. One of critical components in NDN is cache. Caching solves bandwidth usage, server load, and service time. Some research about caching has been conducted, but improvement...

Information-Centric Networking with caching is a very promising future network architecture. The research on its cache deployment strategy divided into three categories, namely, noncooperative cache, explicit collaboration and implicit cache. Noncooperative can cause problems such as high content repetition rate in the web space. Explicit generally reflects best effect but requires lot of commu...

We improve the performance of main-memory binary search trees (including AVL and red-black trees) by applying cache-sensitive and cacheoblivious memory layouts. We relocate tree nodes in memory according to a multi-level cache hierarchy, also considering the conflict misses produced by set-associative caches. Moreover, we present a method to improve onelevel cache-sensitivity without increasing...

B-Trees have been traditionally optimized for I/O performance with disk pages as tree nodes. Recently, researchers have proposed new types of B-Trees optimized for CPU cache performance in main memory environments, where the tree node sizes are one or a few cache lines. Unfortunately, due primarily to this large discrepancy in optimal node sizes, existing disk-optimized B-Trees su er from poor ...

Dynamic Adaptive Streaming over HTTP (DASH) has prevailed as the dominant way of video transmission Internet. This technology is based on receiving small sequential segments from a server. However, one challenge that not been adequately examined obtainment in serves both needs network and improvement Quality Experience (QoE) users. One effective to achieve this implement study caching DASH tech...
