One of the challenges faced by data-intensive computing is the problem of stragglers, which can significantly increase the job completion time. Various proactive and reactive straggler mitigation techniques have been developed to address the problem. The straggler identification scheme is a crucial part of the straggler mitigation techniques, as only when stragglers are detected not only correctly...
The Dedicated Short Range Communication (DSRC) technology has been used in Vehicular communication to enable short-lived safety and non-safety applications based on Vehicle to Vehicle (V2V) communications over the Control Channel (CCH) and Vehicle to Infrastructure (V2I) communications over the Service Channels (SCHs) in Vehicular Ad hoc Networks (VANETs). With the under-utilized advanced computation,...
Virtualization technology has played an increasingly important role in modern datacenters and cloud computing. With the rapid development of hardware, the capability of single physical server has become more and more powerful. So it has been a trend that deploying multiple VMs (Virtual Machines) on a single physical host, which is so called virtual machine consolidation. High degree of VM consolidation...
Quality of Resilience (QoR) is natively connected to cloud computing to enable high-availability of services and secure access to information. QoR, in such dynamic contexts, cannot simply rely on reactive protection models, such as the primary-backup model supported by the Stream Control Transport Protocol (SCTP). Indeed, proactive mechanisms are required to enable an optimal QoR. In this paper we...
With the increasingly widespread application of cloud computing, multiple cloud storage platforms have emerged, such as Dropbox, GoogleDrive, OneDrive, etc. These synchronization technology tools are based on specific platform and vary in time synchronization, bandwidth, file types and working offline synchronization capabilities. Most of them are facing time delay, bandwidth overhead problems. Based...
Our paper presents solutions using erasure coding, parallel connections to storage cloud and limited chunking (i.e., dividing the object into a few smaller segments) together to significantly improve the delay performance of uploading and downloading data in and out of cloud storage. TOFEC is a strategy that helps front-end proxy adapt to level of workload by treating scalable cloud storage (e.g....
