+
+Manual Build:
+=============
+1. Download DPDK supported version from dpdk.org
+
+   - http://dpdk.org/browse/dpdk/snapshot/dpdk-$DPDK_RTE_VER.zip
+2. unzip  dpdk-$DPDK_RTE_VER.zip and apply dpdk patches only in case of 16.04
+   (Not required for other DPDK versions)
+
+   - cd dpdk
+
+         - patch -p1 < VNF_CORE/patches/dpdk_custom_patch/i40e-fix-link-management.patch
+         - patch -p1 < VNF_CORE/patches/dpdk_custom_patch/i40e-fix-Rx-hang-when-disable-LLDP.patch
+         - patch -p1 < VNF_CORE/patches/dpdk_custom_patch/i40e-fix-link-status-change-interrupt.patch
+         - patch -p1 < VNF_CORE/patches/dpdk_custom_patch/i40e-fix-VF-bonded-device-link-down.patch
+         - patch -p1 < $VNF_CORE/patches/dpdk_custom_patch/disable-acl-debug-logs.patch
+         - patch -p1 < $VNF_CORE/patches/dpdk_custom_patch/set-log-level-to-info.patch
+
+   - build dpdk
+
+        - make config T=x86_64-native-linuxapp-gcc O=x86_64-native-linuxapp-gcc
+        - cd x86_64-native-linuxapp-gcc
+        - make
+
+   - Setup huge pages
+
+        - For 1G/2M hugepage sizes, for example 1G pages, the size must be specified
+          explicitly and can also be optionally set as the default hugepage size for
+          the system. For example, to reserve 8G of hugepage memory in the form of
+          eight 1G pages, the following options should be passed to the kernel:
+          * default_hugepagesz=1G hugepagesz=1G hugepages=8  hugepagesz=2M hugepages=2048
+        - Add this to Go to /etc/default/grub configuration file.
+        - Append "default_hugepagesz=1G hugepagesz=1G hugepages=8 hugepagesz=2M hugepages=2048"
+            to the GRUB_CMDLINE_LINUX entry.
+
+3. Setup Environment Variable
+
+   - export RTE_SDK=<samplevnf>/dpdk
+   - export RTE_TARGET=x86_64-native-linuxapp-gcc
+   - export VNF_CORE=<samplevnf>
+     or using ./tools/setenv.sh
+
+4. Build vCGNAPT VNFs
+
+   - cd <samplevnf>/VNFs/vCGNAPT
+   - make clean
+   - make
+
+5. An vCGNAPT executable will be created at the following location
+
+   - <samplevnf>/VNFs/vCGNAPT/build/vCGNAPT

+vCGNAPT - Readme
+========================================================
+
+Introduction
+==============
+This application implements vCGNAPT. The idea of vCGNAPT is to extend the life of
+the service providers IPv4 network infrastructure and mitigate IPv4 address
+exhaustion by using address and port translation in large scale. It processes the
+traffic in both the directions.
+
+It also supports the connectivity between the IPv6 access network to IPv4 data network
+using the IPv6 to IPv4 address translation and vice versa.
+
+About DPDK
+----------
+The DPDK IP Pipeline Framework provides set of libraries to build a pipeline
+application. In this document, CG-NAT application will be explained with its
+own building blocks.
+
+This document assumes the reader possess the knowledge of DPDK concepts and IP
+Pipeline Framework. For more details, read DPDK Getting Started Guide, DPDK
+Programmers Guide, DPDK Sample Applications Guide.
+
+Scope
+==========
+This application provides a standalone DPDK based high performance vCGNAPT
+Virtual Network  Function implementation.
+
+Features
+===========
+The vCGNAPT VNF currently supports the following functionality:
+  • Static NAT
+  • Dynamic NAT
+  • Static NAPT
+  • Dynamic NAPT
+  • ARP (request, response, gratuitous)
+  • ICMP (terminal echo, echo response, passthrough)
+  • ICMPv6 and ND (Neighbor Discovery)
+  • UDP, TCP and ICMP protocol passthrough
+  • Multithread support
+  • Multiple physical port support
+  • Limiting max ports per client
+  • Limiting max clients per public IP address
+  • Live Session tracking to NAT flow
+  • NAT64
+  • PCP Support
+  • ALG SIP
+  • ALG FTP
+
+High Level Design
+====================
+The Upstream path defines the traffic from Private to Public and the downstream
+path defines the traffic from Public to Private. The vCGNAPT has same set of
+components to process Upstream and Downstream traffic.
+
+In vCGNAPT application, each component is constructed as IP Pipeline framework.
+It includes Master pipeline component, load balancer pipeline component and vCGNAPT
+pipeline component.
+
+A Pipeline framework is collection of input ports, table(s), output ports and
+actions (functions). In vCGNAPT pipeline, main sub components are the Inport function
+handler, Table and Table function handler. vCGNAPT rules will be configured in the
+table which translates egress and ingress traffic according to physical port
+information from which side packet is arrived. The actions can be forwarding to the
+output port (either egress or ingress) or to drop the packet.

+==========================
+The idea of vCGNAPT is to extend the life of the service providers IPv4 network infrastructure
+and mitigate IPv4 address exhaustion by using address and port translation in large scale.
+It processes the traffic in both the directions.

+
+Components of vCGNAPT
+=====================
+
+In vCGNAPT, each component is constructed as a packet framework. It includes Master pipeline
+component, driver, load balancer pipeline component and vCGNAPT worker pipeline component. A
+pipeline framework is a collection of input ports, table(s), output ports and actions
+(functions).
+
+Receive and transmit driver
+----------------------------
+Packets will be received in bulk and provided to load balancer thread. The transmit takes
+packets from worker thread in a dedicated ring and sent to the hardware queue.
+
+ARPICMP pipeline
+------------------------
+ARPICMP pipeline is responsible for handling all l2l3 arp related packets.
+
+This component does not process any packets and should configure with Core 0,
+to save cores for other components which processes traffic. The component
+is responsible for:
+1. Initializing each component of the Pipeline application in different threads
+2. Providing CLI shell for the user
+3. Propagating the commands from user to the corresponding components.
+4. ARP and ICMP are handled here.
+
+Load Balancer pipeline
+------------------------
+Load balancer is part of the Multi-Threaded CGMAPT release which distributes
+the flows to Multiple ACL worker threads.
+
+Distributes traffic based on the 2 or 5 tuple (source address, source port,
+destination  address, destination port and protocol) applying an XOR logic
+distributing the  load to active worker threads, thereby maintaining an
+affinity of flows to  worker threads.
+
+Tuple can be modified/configured using configuration file
+
+vCGNAPT - Static
+====================
+The vCGNAPT component performs translation of private IP & port to public IP &
+port at egress side and public IP & port to private IP & port at Ingress side
+based on the NAT rules added to the pipeline Hash table. The NAT rules are
+added to the Hash table via user commands. The packets that have a matching
+egress key or ingress key in the NAT table will be processed to change IP &
+port and will be forwarded to the output port. The packets that do not have a
+match will be taken a default action. The default action may result in drop of
+the packets.
+
+vCGNAPT - Dynamic
+===================
+The vCGNAPT component performs translation of private IP & port to public IP & port
+at egress side and public IP & port to private IP & port at Ingress side based on the
+NAT rules added to the pipeline Hash table. Dynamic nature of vCGNAPT refers to the
+addition of NAT entries in the Hash table dynamically when new packet arrives. The NAT
+rules will be added to the Hash table automatically when there is no matching entry in
+the table and the packet is circulated through software queue. The packets that have a
+matching egress key or ingress key in the NAT table will be processed to change IP &
+port and will be forwarded to the output port defined in the entry.
+
+Dynamic vCGNAPT acts as static one too, we can do NAT entries statically. Static NAT
+entries port range must not conflict to dynamic NAT port range.
+
+vCGNAPT Static Topology
+------------------------
+
+::
+
+  IXIA(Port 0)-->(Port 0)VNF(Port 1)-->(Port 1) IXIA
+  operation:
+  Egress --> The packets sent out from ixia(port 0) will be CGNAPTed to ixia(port 1).
+  Igress --> The packets sent out from ixia(port 1) will be CGNAPTed to ixia(port 0).
+
+vCGNAPT Dynamic Topology (L4REPLAY)
+------------------------------------
+
+::
+
+  IXIA(Port 0)-->(Port 0)VNF(Port 1)-->(Port 0)L4REPLAY
+  operation:
+  Egress --> The packets sent out from ixia will be CGNAPTed to L3FWD/L4REPLAY.
+  Ingress --> The L4REPLAY upon reception of packets (Private to Public Network),
+  will immediately replay back the traffic to IXIA interface. (Pub -->Priv).
+
+How to run L4Replay
+--------------------
+After the installation of samplevnf:
+
+::
+
+ go to <samplevnf/VNFs/L4Replay>
+ ./buid/L4replay -c  core_mask -n no_of_channels(let it be as 2) -- -p PORT_MASK --config="(port,queue,lcore)"
+     eg: ./L4replay -c 0xf -n 4 -- -p 0x3 --config="(0,0,1)"
+
+Installation, Compile and Execution
