 Data Plane
 ----------
 
 OPNFV extends Linux virtual networking capabilities by using virtual switching
-and routing components. The OPNFV community proactively engages with these source
+and routing components. The OPNFV community proactively engages with the following open source
 communities to address performance, scale and resiliency needs apparent in carrier
 networks.
 
-* FD.io (Fast data - Input/Output): a collection of several projects and libraries to
-  amplify the transformation that began with Data Plane Development Kit (DPDK) to support
-  flexible, programmable and composable services on a generic hardware platform.
-* Open vSwitch: a production quality, multilayer virtual switch designed to enable
-  massive network automation through programmatic extension, while still supporting standard
-  management interfaces and protocols.
+* OVS (Open vSwitch): a production quality, multilayer virtual switch designed to enable massive

+* FD.io (Fast data - Input/Output): a high performance alternative to Open vSwitch, the core engine of
+  FD.io is a vector processing engine (VPP). VPP processes a number of packets in parallel instead of one at
+  a time thus significantly improving packet throughput.
+* DPDK:  a set of libraries that bypass the kernel and provide polling mechanisms, instead of interrupt based operations,
+  to speed up packet processing. DPDK works with both OVS and FD.io.

+MANO
+----
+
+OPNFV integrates open source MANO projects for NFV orchestration and VNF management.
+New MANO projects are constantly being added, currently OPNFV integrates:
+* OpenBaton: Open Baton is a ETSI NFV compliant Management and Orchestration (MANO) Framework.
+  It enables virtual Network Services deployments on top of heterogeneous NFV Infrastructures.
+  OpenBaton is also used to deploy vIMS (clearwater and openIMS).
