+- DPDK supported versions ($DPDK_RTE_VER = 16.04, 16.11, 17.02 or 17.05): Downloaded and installed via vnf_build.sh or manually from [here] (http://fast.dpdk.org/rel/)
+- libpcap-dev
+- libzmq
+- libcurl
+
+---------------------
+Environment variables
+---------------------
+Apply all the additional patches in 'patches/dpdk_custom_patch/' and build dpdk
+
+::
+
+ export RTE_SDK=<dpdk directory>
+ export RTE_TARGET=x86_64-native-linuxapp-gcc
+
+This is done by vnf_build.sh script.
+
+Auto Build:
+===========
+$ ./tools/vnf_build.sh in samplevnf root folder
+
+Follow the steps in the screen from option [1] --> [9] and select option [8]
+to build the vnfs.
+It will automatically download selected DPDK version and any required patches
+and will setup everything and build vACL VNFs.
+
+Following are the options for setup:
+
+::
+
+ ----------------------------------------------------------
+ Step 1: Environment setup.
+ ----------------------------------------------------------
+ [1] Check OS and network connection
+ [2] Select DPDK RTE version
+
+ ----------------------------------------------------------
+ Step 2: Download and Install
+ ----------------------------------------------------------
+ [3] Agree to download
+ [4] Download packages
+ [5] Download DPDK zip
+ [6] Build and Install DPDK
+ [7] Setup hugepages
+
+ ----------------------------------------------------------
+ Step 3: Build VNFs

+
+ [9] Exit Script
+
+An vACL executable will be created at the following location
+samplevnf/VNFs/vACL/build/vACL
+
+
+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

+
+ - 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 vACL VNFs
+
+ - cd <samplevnf>/VNFs/vACL
+ - make clean
+ - make

+vACL - Readme
+========================================================
+
+Introduction
+=================
+This application implements Access Control List (ACL). ACL is typically
+used for rule based policy enforcement. It restricts access to a destination
+IP address/port based on various header fields, such as source IP address/port,
+destination IP address/port and protocol. It is built on top of DPDK and
+uses the packet framework infrastructure.
+
+
+----------
+About DPDK
+----------
+The DPDK IP Pipeline Framework provides a set of libraries to build a pipeline
+application. In this document, vACL will be explained in detail with its own
+building blocks.
+
+This document assumes the reader possesses the knowledge of DPDK concepts and
+packet 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 vACL Virtual
+Network Function implementation.
+
+Features
+===========
+The vACL VNF currently supports the following functionality
+ • CLI based Run-time rule configuration.(Add, Delete, List, Display, Clear, Modify)
+ • Ipv4 and ipv6 standard 5 tuple packet Selector support.
+ • Multithread support
+ • Multiple physical port support
+ • Hardware and Software Load Balancing
+ • L2L3 stack support for ARP/ICMP handling
+ • ARP (request, response, gratuitous)
+ • ICMP (terminal echo, echo response, passthrough)
+ • ICMPv6 and ND (Neighbor Discovery)
+
+High Level Design
+====================
+The ACL Filter performs bulk filtering of incoming packets based on rules in current ruleset,
+discarding any packets not permitted by the rules. The mechanisms needed for building the
+rule database and performing lookups are provided by the DPDK API.
+http://dpdk.org/doc/api/rte__acl_8h.html
+
+The Input FIFO contains all the incoming packets for ACL filtering. Packets will be dequeued
+from the FIFO in bulk for processing by the ACL. Packets will be enqueued to the output FIFO.
+The Input and Output FIFOs will be implemented using DPDK Ring Buffers.
+
+The DPDK ACL example: http://dpdk.org/doc/guides/sample_app_ug/l3_forward_access_ctrl.html
+#figure-ipv4-acl-rule contains a suitable syntax and parser for ACL rules.
+
+Components of vACL
+=======================
+In vACL, each component is constructed using packet framework pipelines.
+It includes Rx and Tx Driver, Master pipeline, load balancer pipeline and
+vACL worker pipeline components. 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 LoadBalancer(LB) thread.
+Transimit takes packets from worker threads in a dedicated ring and sent to
+hardware queue.
+
+---------------------------
+Master Pipeline
+---------------------------
+The Master component is part of all the IP Pipeline applications. This component
+does not process any packets and should configure with Core 0, to allow
+other cores for processing of the traffic. This component is responsible for
+1. Initializing each component of the Pipeline application in different threads
+2. Providing CLI shell for the user control/debug
+3. Propagating the commands from user to the corresponding components
+
+---------------------------
+ARPICMP Pipeline
+---------------------------
+This pipeline processes the APRICMP packets.
+
+---------------------------
+TXRX Pipelines
+---------------------------
+The TXTX and RXRX pipelines are pass through pipelines to forward both ingress
+and egress traffic to Loadbalancer. This is required when the Software
+Loadbalancer is used.
+
+---------------------------
+Load Balancer Pipeline
+---------------------------
+The vACL support both hardware and software balancing for load blalcning of
+traffic across multiple VNF threads. The Hardware load balncing require support
+from hardware like Flow Director for steering of packets to application through
+hardware queues.
+
+The Software Load balancer is also supported if hardware loadbalancing can't be
+used for any reason. The TXRX along with LOADB pipeline provides support for
+software load balancing by distributing the flows to Multiple vACL worker
+threads.
+Loadbalancer (HW or SW) distributes traffic based on the 5 tuple (src addr, src
+port, dest addr, dest port and protocol) applying an XOR logic distributing to
+active worker threads, thereby maintaining an affinity of flows to worker
+threads.
+
+---------------------------
+vACL Pipeline
+---------------------------
+The vACL performs the rule-based packet filtering.
+
+vACL Topology
+------------------------
+
+::
+
+ IXIA(Port 0)-->(Port 0)VNF(Port 1)-->(Port 1) IXIA
+ operation:
+
+ Egress --> The packets sent out from ixia(port 0) will be sent through ACL to ixia(port 1).
+
+ Igress --> The packets sent out from ixia(port 1) will be sent through ACL to ixia(port 0).
+
+vACL Topology (L4REPLAY)
+------------------------------------
+
+::
+
+ IXIA(Port 0)-->(Port 0)VNF(Port 1)-->(Port 0)L4REPLAY
+
+ operation:
+
+ Egress --> The packets sent out from ixia will pass through vACL 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)"
+
