vSphere Network I/O Control version 3 introduces(معرفی می کند) a mechanism to reserve bandwidth for system traffic based on the capacity(ظرفیت) of the physical adapters on a host.

It enables fine-grained resource control(کنترل دقیق منابع) at the VM network adapter level similar to the model that you use for allocating CPU and memory resources.

Version 3 of the Network I/O Control feature offers improved network resource reservation and allocation across the entire switch.
