Paper Abstract:
|
We propose a life cycle-based dynamic virtual network monitoring system that focuses on the varying failure rate in the
life cycle of the VM and selects the target device for dynamic and continuous network monitoring. When using a
combination of server monitoring with ping and network connection check with Ethernet OAM, the system sets higher
priorities to the port connected to a long running server, and the port within a certain time after the connection change or
virtual machine addition is set. The system then selects the ports from the higher priority port to be monitored by Ethernet
OAM. As a result of the evaluation by the simulation, by dynamically selecting the port to be monitored for Ethernet OAM
using the proposed method, it was confirmed that the average locating time of the VM failure is reduced by 2.2% compared
to the conventional method. In the data center for cloud services running many VMs, it is possible to shorten the recovery
from VM failure while suppressing the number of objects monitored by Ethernet OAM by using this method. |
