3. What is DPDK? – Overview Definition Overview of DPDK
A set of libraries and drivers for fast packet processing on x86 platform
Working in Linux user-land
Open source project
Overview of DPDK

4. What is DPDK? – Overview
Comparison between previous network driver and DPDK
Typical network driver
DPDK

5. What is DPDK? – Features DPDK libraries Buffer management
Reducing a significant amount of the time to allocate or de-allocate buffers in memory pools
Queue/Ring functions
Safe lockless queues to allow different software components for packet processing
To avoid unnecessary wait times
Packet flow classification
To provide efficient mechanism to process packets
NIC poll mode library
No asynchronous, interrupt-based signaling mechanisms  polling based
Memory manager
Responsible for allocating pools of objects in memory
Pool: huge page memory space

6. What is DPDK? – Supported NICs

8. What is FD.io? – Overview Definition of FD.io
Fast Data – input/output
Collection of several projects and libraries to support flexible, programmable, and composable services on a generic hardware
To develop Software-Defined Infrastructure
FD.io uses DPDK for network IO Layer getting packets to/from NICs and cores

9. What is FD.io? – Features
Projects of FD.io

10. What is FD.io? – Features VPP Heart of FD.io
Vector Packet Processing technology
Rapid packet processing development platform highly performing network applications
Runs on commodity CPUs and leverages DPDK
Run as a user-space application
VPP creates a vector of packet
VPP processes them using a directed graph of nodes
Vector-level processing through graph node before moving on to next graph node

11. What is FD.io? – Features Honeycomb CSIT Java-based agent
VPP management agent
Providing RESTCONF and NETCONF interfaces
CSIT
Continuous system integration and testing
Test automation
