 Data Plane Development Kit (DPDK) on Azure offers a faster user-space packet processing framework for performance-intensive applications. This framework bypasses the virtual machine’s kernel network stack.
 
-In typical packet processing that uses the kernel network stack, the process is interrupt-driven. When the network interface receives incoming packets, there is a kernel interrupt to process the packet and a context switch from the kernel space to the user space. DPDK eliminates context switching and the interrupt-driven method in favor of a user-space implementation that uses poll mode drivers for fast packet processing.

 DPDK consists of sets of user-space libraries that provide access to lower-level resources. These resources can include hardware, logical cores, memory management, and poll mode drivers for network interface cards.

 ## Prerequisites
 
-Accelerated networking must be enabled on a Linux virtual machine. The virtual machine should have at least two network interfaces, with one interface for management. Enabling Accelerated networking on management interface is not recommended. Learn how to [create a Linux virtual machine with accelerated networking enabled](create-vm-accelerated-networking-cli.md).
