This paper performs controlled experiments with two popular virtualization techniques, Linux-
VServer and Xen, to examine the effects of virtualization on packet sending and receiving …

Virtualization is central to cloud computing systems. It abstracts computing resources to be
shared among multiple virtual machines (VMs) that can be easily managed to run multiple …

Most of the work on VM network performance has focused so far on bulk TCP traffic, which
covers classical applications of virtualization. Completely new “paravirtualized …

In this paper, we present the design of a performance isolation benchmark that quantifies the
degree to which a virtualization system limits the impact of a misbehaving virtual machine on …

Currently, there is a strong effort of the research community in rethinking the Internet
architecture to cope with its current limitations and support new requirements. Many …

There have been significant studies on virtual machines (VMs), including their power
consumption in performing different types of tasks. The VM's power consumption with …

Concerns have been raised about the performance of PC-based virtual routers as they do
packet processing in software. Furthermore, it becomes challenging to maintain isolation …

I/O virtualization techniques developed recently have led to significant changes in network
processing. These techniques require network packets go through additional layers of …

In this paper we tackle the problem of providing Quality of Service guarantees to virtualized
applications, focusing on computing and networking guarantees. We propose a mechanism …

Network virtualization stacks are the linchpins of public clouds. A key goal is to provide
performance isolation so that workloads on one Virtual Machine (VM) do not adversely …
