Abstract:
Data centers have become the nextgeneration
computing platforms for enterprises
and Internet users. This is primarily due to the
economic and technical advantages of resource
sharing in data centers. By sharing computing
and storage resources through services such as
cloud computing or software-as-a-service (SaaS),
users can amortize the cost of hardware and
software. Because of the virtualization of
resources, a new virtualized network access layer
has been introduced to interconnect VMs within
the data centers. In data center, hosts have been
recently employed virtual switch to interconnect
virtual machines (VMs) within data center
networks. Virtual Switch is essential to control
and manage VM within the hosts. Open vSwitch,
a network switch specifically built for Xen
virtualization environment is presented. The
design and advantages of Open vSwitch is
described. And then secure VM networking is
proposed by using Open vSwitch. By combining
Intrusion Detection System with Open vSwitch,
more secure virtual networking can be
established because Open vSwitch can get inter
VM traffic logs directly and can perform more
controls VM communication.
