Abstract
The swift acceptance and the widespread use of virtual

environments has substantially increased the stress on networks

as each of the operating systems running in parallel sends out

packets over the same network. As an increased number of

packets traverse a network, the importance to continuously

monitor whether the network is providing satisfactory service

has increased. The metrics for such analyses includes delay,

jitter, packet loss and available path capacity. The basic

parameter required to quantify these metrics is the timestamping

values of the packets. The purpose of this research

work is to characterize the impact of virtualization on a... (More)

values of the packets. The purpose of this research

work is to characterize the impact of virtualization on a PC's

time-stamping process. Operating system virtualization is

employed where the time-stamping is done by the operating

system kernel. CPU load and packet generating parameters are

varied in order to study about the effect of virtualization on the

time-stamping process under different operating conditions. (Less)
