(c) opnfv, national center of scientific research "demokritos" and others. + +======================================================== +Virtual ACL - vACL +======================================================== + +1. 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. + +2. Scope +========== +This application provides a standalone DPDK based high performance vACL Virtual +Network Function implementation. + +3. 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) + +4. 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. + +=================== +5. 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: +-------------------- +:: + 1. After the installation of samplevnf: + go to <samplevnf/VNFs/L4Replay> + 2. ./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)" + +6.
