Virtualization

Dynamic Migration of Computation Through Virtualization of the Mobile Platform

Free registration required

Executive Summary

Virtualization and live migration techniques have long been used in the enterprise server space and have been tuned to address data center usages. These capabilities are now expanding to personal computers including desktops and laptops and more recently into smaller mobile devices such as Netbooks and Mobile Internet Devices (MID). Hardware support for virtualization in these platforms, such as that offered by Intel Atom processor, enables the use of existing operating systems and virtualization software. The experiments demonstrate that live migration can be used to dynamically offload computation to a nearby desktop computer from a Netbook, taking only 25 seconds over a 100Mbps Ethernet network and approximately 100 seconds over an 802.11n interface with a measured throughput of 70Mbps.
