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. - -vCGNAPT Graphical Overview -========================== -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. - -.. code-block:: console - - +------------------+ - | +-----+ - | Private consumer | CPE |---------------+ - | IPv4 traffic +-----+ | - +------------------+ | - +------------------+ v +----------------+ - | | +------------+ | | - | Private IPv4 | | vCGNAPT | | Public | - | access network | | NAT44 | | IPv4 traffic | - | | +------------+ | | - +------------------+ | +----------------+ - +------------------+ | - | +-----+ | - | Private consumer| CPE |-----------------+ - | IPv4 traffic +-----+ - +------------------+ - Figure 1: vCGNAPT deployment in Service provider network - - - -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.
