vSnoop: Improving TCP Throughput in Virtualized Environments via Acknowledgement Offload
By Ardalan Kangarlou, Sahan Gamage, Ramana Rao Kompella, Dongyan Xu
Issue Date:November 2010
Virtual machine (VM) consolidation has become a common practice in clouds, Grids, and datacenters. While this practice leads to higher CPU utilization, we observe its negative impact on the TCP throughput of the consolidated VMs: As more VMs share the same...
VNsnap: Taking Snapshots of Virtual Networked Infrastructures in the Cloud
IEEE Transactions on Services Computing
By Ardalan Kangarlou,Patrick Eugster,Dongyan Xu
Issue Date:September 2012
A virtual networked infrastructure (VNI) consists of virtual machines (VMs) connected by a virtual network. Created for individual users on a shared cloud infrastructure, VNIs reflect the concept of "Infrastructure as a Service” (IaaS) as p...
Protocol Responsibility Offloading to Improve TCP Throughput in Virtualized Environments
Found in: ACM Transactions on Computer Systems (TOCS)
By Ardalan Kangarlou, Dongyan Xu, Ramana Rao Kompella, Sahan Gamage
Issue Date:August 2013
Virtualization is a key technology that powers cloud computing platforms such as Amazon EC2. Virtual machine (VM) consolidation, where multiple VMs share a physical host, has seen rapid adoption in practice, with increasingly large numbers of VMs per machi...
Taking snapshots of virtual networked environments
Found in: Proceedings of the 3rd international workshop on Virtualization technology in distributed computing (VTDC '07)
By Ardalan Kangarlou, Dongyan Xu, Patrick Eugster, Paul Ruth
Issue Date:November 2007
The capture of global, consistent snapshots of a distributed computing session or system is essential to the system's reliability, manageability, and accountability. Despite the large body of work at the application, library, and operating system levels, w...
