When choosing between a piece of cake now versus a slimmer waistline in the future, many of us have difficulty with self-control. Food-caching species, however, regularly hide food for later recovery, sometimes waiting months before retrieving their caches. It remains unclear whether these long-term choices generalize outside of the caching domain. We hypothesized that the ability to save for t...

The popularity of video-on-demand (VoD) streaming has grown dramatically over the World Wide Web. Most users in VoD P2P networks have to wait a long time in order to access their requesting videos. Therefore, reducing waiting time to access videos is the main challenge for VoD P2P networks. In this paper, we propose a novel algorithm for caching video based on peers' priority and video's popula...

With the increasing demand for document transfer services such as the World Wide Web comes a need for better resource management to reduce the latency of documents in these systems. To address this need, we analyze the potential for document caching at the application level in document transfer services. We have collected traces of actual executions of Mosaic, re ecting over half a million user...

While there has been very substantial progress in practical algorithms for satisfiability, there are many related logical problems where satisfiability alone is not enough. One particularly useful extension to satisfiability is the associated counting problem, #SAT, which requires computing the number of assignments that satisfy the input formula. #SAT’s practical importance stems in part from ...

Corvids recognize when their caches are at risk of being stolen by others and have developed strategies to protect these caches from pilferage. For instance, Clark's nutcrackers will suppress the number of caches they make if being observed by a potential thief. However, cache protection has most often been studied using competitive contexts, so it is unclear whether corvids can adjust their ca...

Internet infrastructure is a key enabler of e-business. The infrastructure consists of backbone networks (such as UUNET and AT&T), access networks (such as AOL and Earthlink), content delivery networks (CDNs, such as Akamai) and other caching service providers. Together, all of the players make up the digital supply chain for information goods. Caches provisioned by CDNs and other entities are ...

The explosion of mobile video traffic imposes tremendous challenges on present cellular networks. To alleviate the pressure on backhaul links and to enhance the quality of experience (QoE) of video streaming service, small cell base stations (SBS) with caching ability are introduced to assist the content delivery. In this paper, we present the first study on the optimal caching strategy of scal...
