When Queueing Meets Coding: Optimal-Latency Data Retrieving Scheme in Storage Clouds
Shengbo Chen, Yin Sun, Ulas C. Kozat +5
In this paper, we study the problem of reducing the delay of downloading data from cloud storage systems by leveraging multiple parallel threads, assuming that the data has been en…
On Throughput-Delay Optimal Access to Storage Clouds via Load Adaptive Coding and Chunking
Guanfeng Liang, Ulas C. Kozat
Recent literature including our past work provide analysis and solutions for using (i) erasure coding, (ii) parallelism, or (iii) variable slicing/chunking (i.e., dividing an objec…
On Diagnosis of Forwarding Plane via Static Forwarding Rules in Software Defined Networks
Ulas C. Kozat, Guanfeng Liang, Koray Kokten
Software Defined Networks (SDN) decouple the forwarding and control planes from each other. The control plane is assumed to have a global knowledge of the underlying physical and/o…
TOFEC: Achieving Optimal Throughput-Delay Trade-off of Cloud Storage Using Erasure Codes
Guanfeng Liang, Ulas C. Kozat
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 si…
FAST CLOUD: Pushing the Envelope on Delay Performance of Cloud Storage with Coding
Guanfeng Liang, Ulas C. Kozat
Our paper presents solutions that can significantly improve the delay performance of putting and retrieving data in and out of cloud storage. We first focus on measuring the delay…
Iterative Approximate Byzantine Consensus in Arbitrary Directed Graphs - Part II: Synchronous and Asynchronous Systems
Nitin Vaidya, Lewis Tseng, Guanfeng Liang
This report contains two related sets of results with different assumptions on synchrony. The first part is about iterative algorithms in synchronous systems. Following our previou…
