-Introduction
-===============
-The virtual firewall (vFW) is an application implements Firewall. vFW is used
-as a barrier between secure internal and an un-secure external network. The
-firewall performs Dynamic Packet Filtering. This involves keeping track of the
-state of Layer 4 (Transport)traffic,by examining both incoming and outgoing
-packets over time. Packets which don't fall within expected parameters given
-the state of the connection are discarded. The Dynamic Packet Filtering will
-be performed by Connection Tracking component, similar to that supported in
-linux. The firewall also supports Access Controlled List(ACL) for rule based
-policy enforcement. Firewall is built on top of DPDK and uses the packet library.
-
-----------
-About DPDK
-----------
-The DPDK IP Pipeline Framework provides a set of libraries to build a pipeline
-application. In this document, vFW 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 vFW Virtual
-Network Function implementation.
-
-Features
-===========
-The vFW VNF currently supports the following functionality:
-  • Basic packet filtering (malformed packets, IP fragments)
-  • Connection tracking for TCP and UDP
-  • Access Control List for rule based policy enforcement
-  • SYN-flood protection via Synproxy* for TCP
-  • UDP, TCP and ICMP protocol pass-through
-  • CLI based enable/disable connection tracking, synproxy, basic packet
-    filtering
-  • 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 Firewall performs basic filtering for malformed packets and dynamic packet
-filtering incoming packets using the connection tracker library.
-The connection data will be stored using a DPDK hash table. There will be one
-entry in the hash table for each connection. The hash key will be based on source
-address/port,destination address/port, and protocol of a packet. The hash key
-will be processed to allow a single entry to be used, regardless of which
-direction the packet is flowing (thus changing the source and destination).
-The ACL is implemented as libray stattically linked to vFW, which is used for
-used for rule based packet filtering.
-
-TCP connections and UDP pseudo connections will be tracked separately even if
-theaddresses and ports are identical. Including the protocol in the hash key
-will ensure this.
-
-The Input FIFO contains all the incoming packets for vFW filtering.  The vFW
-Filter has no dependency on which component has written to the Input FIFO.
-Packets will be dequeued from the FIFO in bulk for processing by the vFW.
-Packets will be enqueued to the output FIFO.
-The software or hardware loadbalancing can be used for traffic distribution
-across multiple worker threads. The hardware loadbalancing require ethernet
-flow director support from hardware (eg. Fortville x710 NIC card).
-The Input and Output FIFOs will be implemented using DPDK Ring Buffers.
-
-Components of vFW
-====================
-
-In vFW, each component is constructed using packet framework pipelines.
-It includes Rx and Tx Driver, Master pipeline, load balancer pipeline and
-vfw 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 vFW support both hardware and software balancing for load balancing of
-traffic across multiple VNF threads. The Hardware load balancing 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 load balancing 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 vFW 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.
-
----------------
-vFW Pipeline
----------------
-The vFW performs the basic packet filtering and will drop the invalid and
-malformed packets.The Dynamic packet filtering done using the connection tracker
-library. The packets are processed in bulk and Hash table is used to maintain
-the connection details.
-Every TCP/UDP packets are passed through connection tracker library for valid
-connection. The ACL library integrated to firewall provide rule based filtering.

-------------------------
-vFW Topology
-------------------------
-
-::
-
-  IXIA(Port 0)-->(Port 0)VNF(Port 1)-->(Port 1) IXIA
-  operation:
-  Egress --> The packets sent out from ixia(port 0) will be Firewalled to ixia(port 1).
-  Igress --> The packets sent out from ixia(port 1) will be Firewalled to ixia(port 0).
-
-------------------------------------
-vFW Topology (L4REPLAY)
-------------------------------------
-
-::
-
-  IXIA(Port 0)-->(Port 0)VNF(Port 1)-->(Port 0)L4REPLAY
-  operation:
-  Egress --> The packets sent out from ixia will pass through vFW 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
-====================================
-Plase refer to <samplevnf>/docs/vFW/INSTALL.rst for installation, configuration,
-compilation and execution.
