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)" - -Installation, Compile and Execution -======================================= -Plase refer to <samplevnf>/docs/vACL/INSTALL.rst for installation, configuration, compilation -and execution. diff --git a/docs/vACL/RELEASE_NOTES.rst b/docs/vACL/RELEASE_NOTES.rst deleted file mode 100644 index c947a371..00000000 --- a/docs/vACL/RELEASE_NOTES.rst +++ /dev/null @@ -1,81 +0,0 @@ -..
