Centralized management is mentioned in the paper.
I am not clear about how to do that.
Which CLI(command line interface) can do that ?
Would you show me an example?
Extending Networking into the Virtualization
> *Centralized management.* The interfaces for configuration
management and asynchronous notification can
be used to create a single logical switch image across
multiple Open vSwitches running on separate physical
servers (similar to [7, 20]). In essence, a global management
process synthesizes a logical view of the switches
and their configuration declarations and lets admins
operate on that view instead of individual switches.
Therefore, as VMs join, leave, and migrate, it is the
responsibility of this management process to ensure any
configuration state remains coupled to the logical entities
for which it was declared.
We have used this interface to build a full CLI for
configuring the network as a whole. The CLI presents
the abstraction of a virtual port to which network configuration
state can be applied (e.g., VLANs, RSPAN, QoS
policies, or ACLs). Each virtual port then corresponds
to a unique VM and follows the VM throughout the
network. As a result, it is possible to query and configure
a collection of virtual switches as if they were a single
