Existing techniques for caching Web objects are not appropriate for the multimedia streaming service. In this paper, the authors focus on the proxy caching problem specifically for multimedia streaming objects. A prototype design and implementation of a proxy caching system – HUSTProxy is proposed. The main contribution of HUSTProxy is its ability of partial video caching, sending rate control ...

Caching as a concept has been highly successful in various aspects of computer system design. Examples of cache memory abound in contemporary designs: a disk buffer cache is a small amount of buffer memory present on a hard drive to speed up the access to the disk; a web cache provides a mechanism for temporary storage of web documents to improve user experience; a DNS cache stores queried resu...

The enterprise information system (EIS) contains databases and other data sources in multiple data centers. Users query the EIS via clients. The client has a working space in the cloud. Caching data in client space will reduce the total execution time of the query. However, the client space has limited resources to store data. There are two options for caching data at the client space: caching ...

We consider the problem of caching with lifetimes, where a lifetime is specified whenever a page is loaded into the cache. The copy of a page loaded into the cache may be used to serve requests to the same page, only until its expiration time. We present a generic method to get an algorithm for caching with lifetimes, from an algorithm for caching without lifetimes. This method works for any co...

Response time is a key differentiation point among electronic commerce (e-commerce) applications. For many e-commerce applications, web pages are created dynamically based on the current state of a business stored in database systems. To improve the response time, many e-commerce websites deploy caching solutions for acceleration of content delivery. There are multiple tiers in the content deli...

This paper investigates a cellular edge caching problem under a very large number of small base stations (SBSs) and users. In this ultra-dense edge caching network (UDCN), conventional caching algorithms may crumble in effectiveness as their complexity increases with the number of SBSs. Furthermore, the performance of a UDCN is highly sensitive to the dynamics of user demand and inter-SBS inter...

Caching is considered widely as an efficient way to reduce access latency and network bandwidth consumption. En-route caching, where caches are associated with routing nodes in the network, is proposed in the context of Web cache to exploit fully the potential of caching. To make sensible replacement and placement decision for en-route caching, traditional caching schemes either engage computat...

Caching dynamic web content is an appealing approach to reduce Internet latency and server load. In aspect-oriented programming, caching is usually presented as an orthogonal aspect that could be automatically integrated to an application. A classical AOP motivating example is adding caching of static data with no underlying consistency. But what about caching dynamic data? In this paper, we ex...

Recent trends show that Internet traffic is increasingly dominated by content, which is accompanied by the exponential growth of traffic. To cope with this phenomena, network caching is introduced to utilize the storage capacity of diverse network devices. In this paper, we first summarize four basic caching placement strategies, i.e., local caching, Device-to-Device (D2D) caching, Small cell B...

Disk caches are employed in distributed le systems to avoid network accesses at clients and to compensate for the speed diierential between main memory and disk at le servers. Because of concerns about volatility, however, write requests have typically not beneetted from the presence of caches. Instead, they have been processed with some sort of write-through or periodic write-back approach to ...
