A paravirtualized operating system is an operating system (OS) that is modified to run in a paravirtualized environment that provides a software interface to virtual machines, similar but not identical to that of the underlying hardware. In paravirtualized mode, the guest OS is explicitly ported for the para application programming interface (API)...
The advantages of Internet exchange points include:

The traffic exchange is managed through a mutual peering agreement conformed to by all ISPs. The ISPs normally specify the routes through the peering relationship. They may choose to route the traffic through their own addresses or addresses of other providers in the network. In some scenarios, the IXP serves as a backup link to allow traffic to pass through in case of a direct link failure.
