A cost-aware auto-scaling approach using the workload prediction in service clouds
Jingqi Yang,Chuanchang Liu,Yanlei Shang,Bo Cheng,Zexiang Mao,Chunhong Liu,Lisha Niu,Junliang Chen +7 more
TL;DR: A novel service cloud architecture is presented, and an auto-scaling mechanism is proposed to scale virtual resources at different resource levels in service clouds that can satisfy the user Service Level Agreement (SLA) while keeping scaling costs low.
Proceedings ArticleDOI
Workload Predicting-Based Automatic Scaling in Service Clouds
TL;DR: A linear regression model is used to predict the workload and an auto-scaling mechanism is proposed to scale virtual resources at different resource levels in service clouds, which can satisfy the user SLA while keeping scaling costs low.
Proceedings ArticleDOI
A low latency scheduling approach for high definition video streaming over heterogeneous wireless networks
TL;DR: A novel scheduling approach named SFL is proposed, which deliberately splits large-size video frames into sub-frames and dispatches each of them onto a different wireless network to the multihomed client to improve the frame-level delay performance for enhancing video quality.
Journal ArticleDOI
SPMLD: Sub-packet based multipath load distribution for real-time multimedia traffic
TL;DR: The Sub-Packet based Multipath Load Distribution model aims to minimize total packet delay by effectively aggregating multiple parallel paths as a single virtual path and outperforms previous flow and packet based load distribution models in total packets delay, end-to-end delay and seldom induces packet reordering.
Proceedings ArticleDOI
A Game Theory of Cloud Service Deployment
TL;DR: A game theoretic method is proposed to optimize both the overall cost and quality of the service deployment in cloud as a congestion game and efficient algorithms are proposed to achieve the equilibrium in polynomial time.
