the ability to discover services in mobile ad hoc network (manet) is a major prerequisite. cluster basedcross layer intelligent service discovery for manet (cbisd) is cluster based architecture, caching ofsemantic details of services and intelligent forwarding using network layer mechanisms. the cluster basedarchitecture using semantic knowledge provides scalability and accuracy. also, the mini...

As ever more big data computations start to be in-memory, I/O throughput dominates the running times of many workloads. For distributed storage, the read throughput can be improved using caching, however, the write throughput is limited by both disk and network bandwidth due to data replication for fault-tolerance. This paper proposes a new file system architecture to enable frameworks to both ...

Coda is a scalable distributed Unix1 file system that provides high availability through the use of two distinct but complementary mechanisms. One mechanism, server replication, stores copies of a file at multiple servers. The other mechanism, disconnected operation, is a mode of execution in which a caching site temporarily assumes the role of a replication site. Disconnected operation is part...

With the increasing demand for document transfer ser vices 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 re...

Component-based programming is a promising approach to distributed application development. It encourages software reuse and promotes the separation (as in aspect-oriented programming) between the components' business implementations and the code managing the used system services. One system service, of particular importance to the distributed computing domain, is replication. It is actually us...

This technical report describes a replicated object store designed to support typically asynchronous collabo-rative activities in mobile environments. The system allows the definition of type-specific data management solutions using an object framework that includes awareness management. High data availability is provided in mobile environments relying on server replication and client caching a...

The expiration-based caching model of the web is generally considered irreconcilable with the dynamic workloads of cloud database services, where expiration dates are not known in advance. In this paper, we present the Cache Sketch data structure which makes expiration-based caching of database records feasible with rich tunable consistency guarantees. The Cache Sketch enables database services...

For many distributed data intensive applications, the default remote invocation of CORBA objects to a server is not acceptable because of performance degradation. Caching can improve performance and scalability of such applications by increasing the locality of data. This paper proposes a caching approach that optimises the default remote invocation behaviour of CORBA clients. Efficient fine-gr...

Initial implementations of Middleware based on standards such as CORBA have concentrated on host and language transparency issues in order to demonstrate interoperability. They have largely adopted a No-Replication approach and have frequently neglected performance-at-scale issues. This has lead to a continuing deployment of either non-scalable Full-Replication approaches or ad-hoc messaging-ba...

AbsfmdI n this paper we discuss the delivery of cacheable streaming content in a network with mobile nodes. Caching and regional replication are important techniques for traffic localizatioo and reduction in load on the network and the content sewer. However traditional caching schemes alone cannot suffice for localization of streaming multimedia traffic in oetworlw with mobile nodes. This is m...
