Challenges, design and analysis of a large-scale p2p-vod system
TLDR
The challenges and the architectural design issues of a large-scale P2P-VoD system based on the experiences of a real system deployed by PPLive are discussed and a number of results on user behavior, various system performance metrics, including user satisfaction, are presented.
An Efficient Partitioning Algorithm for Distributed Virtual Environment Systems
TLDR
An efficient partitioning algorithm is proposed that addresses the scalability issue of designing a large scale DVE system by dynamically divide the virtual world into different partitions and then efficiently assign these partitions to different servers.
Performance Analysis of Disk Arrays under Failure
TLDR
A new variation of the RAID organization is proposed that has significant advantages in both reducing the magnitude of the performance degradation when there is a single failure and can also reduce the mean time to system failure.
A Simple Model for Analyzing P2P Streaming Protocols
TLDR
A simple stochastic model is described that can be used to compare different data-driven downloading strategies based on two performance metrics: continuity (probability of continuous playback), and startup latency (expected time to start playback).
DCAR: Distributed Coding-Aware Routing in Wireless Networks
TLDR
DCAR, the distributed coding-aware routing mechanism which enables the discovery for available paths between a given source and destination and the detection for potential network coding opportunities over much wider network region, is proposed and implemented.
Secure Overlay Cloud Storage with Access Control and Assured Deletion
TLDR
This work design and implement FADE, a secure overlay cloud storage system that achieves fine-grained, policy-based access control and file assured deletion, and associates outsourced files with file access policies, and assuredly deletes files to make them unrecoverable to anyone upon revocations of fileAccess policies.
Optimal recovery of single disk failure in RDP code storage systems
TLDR
This paper proposes an optimal and efficient disk recovery scheme, Row-Diagonal Optimal Recovery (RDOR), for single disk failure of RDP code that has the following properties: it is read optimal in the sense that it issues the smallest number of disk reads to recover the failed disk.
Online Robust Subspace Tracking from Partial Information
This paper presents GRASTA (Grassmannian Robust Adaptive Subspace Tracking Algorithm), an ecient and robust online algorithm for tracking subspaces from highly incomplete information. The algorithm
TaintART: A Practical Multi-level Information-Flow Tracking System for Android RunTime
TLDR
A multi-level information-flow tracking system for the new Android system called TaintART, which employs a multi- level taint analysis technique to minimize the taint tag storage and implements amulti-level privacy enforcement to prevent sensitive data leakage.
DCAR: Distributed Coding-Aware Routing in Wireless Networks
TLDR
DCAR, the distributed coding-aware routing mechanism which enables the discovery for available paths between a given source and destination and the detection for potential network coding opportunities over much wider network region, is proposed and implemented.
