Managing data in a mobile computing environment invariably involves caching or replication. In many cases, a mobile device has access only to data that is stored locally, and much of that data arrives via replication from other devices, PCs, and services. Given portable devices with limited resources, weak or intermittent connectivity, and security vulnerabilities, data replication serves to in...

Private caching and shared caching are the two conventional approaches to managing distributed L2 caches in current multicore processors. Unfortunately, neither shared caching, nor private caching guarantees optimal performance under different workloads, especially when many processor cores and cache slices are provided on a switched network. This paper takes a very different approach from the ...

Replicating Web documents reduces user-perceived delays and wide-area network traffic. Numerous caching and replication protocols have been proposed to manage such replication, while keeping the document copies consistent. We claim however that Web documents have very diverse characteristics, and that no single caching or replication policy can efficiently manage all documents. Instead, we prop...

Data caching is a well-understood technique for improving the performance and availability of wide area distributed applications. The complexity of caching algorithms motivates the need for reusable middleware support to manage caching. To support diverse data sharing needs effectively, a caching middleware must provide a flexible consistency solution that (i) allows applications to express a b...

This memo describes research challenges for Information-Centric Networking. Information-Centric Networking is an approach to evolve the Internet infrastructure to directly support information distribution by introducing uniquely named data as a core Internet principle. Data becomes independent from location, application, storage, and means of transportation, enabling in-network caching and repl...

Live streaming services have gained extreme popularity in recent years. Due to the spiky traffic patterns of live videos, utilizing distributed edge servers improve viewers' quality experience (QoE) has become a common practice nowadays. Nevertheless, current client-driven content caching mechanism does not support pre-caching from cloud edge, resulting considerable amount cache misses video de...

As computers become pervasive in the home and community and homes become better connected, new applications will be deployed over the Internet. Interactive Distributed Applications involve users in multiple locations, across a wide area network, who interact and cooperate by manipulating shared objects. A timely response to user actions, which can potentially update the state of the objects, is...

The tremendous growth of the mobile users' population coupled with the bandwidth requirements of new cellular services are in contrast to the limited spectrum resources that have been allocated for mobile communications. Three caching strategies have been discussed in this paper. One uses Bit sequence, an adaptive cache invalidation algorithm for client/server mobile environments; the next appr...
