Path load balancing is used for distributing workload across an array of paths to increase network reliability and optimize link utilization. However, it is not easy to realize the load balancing globally in traditional networks as the whole status of the network is difficult to obtain. To address this problem, we propose the Fuzzy Synthetic Evaluation Mechanism (FSEM), a path load balancing solution...
The scale and expense of modern data centers motivates running them as efficiently as possible. This paper explores how virtualized data center performance can be improved when network traffic and topology data informs VM placement. Our practical heuristics, tested on network-heavy, scale-out workloads in an 80 server cluster, improve overall performance by up to 70% compared to random placement in...
The paper describes a service model for cost-effective event reporting to clients over a wide-area network. The service provider (SP) maintains multiple protocol mechanisms to replicate the event pages at different proxy nodes of the distribution network. The mechanisms, which embody server-driven and client-driven replica update schemes to synchronize the page copies, reduce the access latency on...
