More technical details will be introduced in this chapter. + +Overview +======== + +Architecture overview +--------------------- +This project provides a placeholder for various sample VNF (Virtual Network Function) +development which includes example reference architecture and optimization methods +related to VNF/Network service for high performance VNFs. + +The sample VNFs are Open Source approximations* of Telco grade VNF’s using +optimized VNF + NFVi Infrastructure libraries, with Performance Characterization +of Sample† Traffic Flows. + +:: + + * Not a commercial product. Encourage the community to contribute and close the feature gaps. + † No Vendor/Proprietary Workloads + +t helps to facilitate deterministic & repeatable bench-marking on Industry +standard high volume Servers. It augments well with a Test Infrastructure to +help facilitate consistent/repeatable methodologies for characterizing & +validating the sample VNFs through OPEN SOURCE VNF approximations and test tools. +The VNFs belongs to this project are never meant for field deployment. +All the VNF source code part of this project requires Apache License Version 2.0. + +Supported deployment: +---------------------- +* Bare-Metal - All VNFs can run on a Bare-Metal DUT +* Standalone Virtualization: All VNFs can run on SV like VPP as switch, ovs, + ovs-dpdk, srioc +* Openstack: Latest Openstack supported + +VNF supported +------------- + - Carrier Grade Network Address Translation (CG-NAT) VNF + :: + The Carrier Grade Network Address and port Translation (vCG-NAPT) is a + VNF approximation extending 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. + - Firewall (vFW) VNF + :: + The Virtual Firewall (vFW) is a VNF approximation serving as a state full + L3/L4 packet filter with connection tracking enabled for TCP, UDP and ICMP. + The VNF could be a part of Network Services (industry use-cases) deployed + to secure the enterprise network from un-trusted network. + - Access Control List (vACL) VNF + :: + The vACL vNF is implemented as a DPDK application using VNF Infrastructure + Library (VIL). The VIL implements common VNF internal, optimized for + Intel Architecture functions like load balancing between cores, IPv4/IPv6 + stack features, and interface to NFV infrastructure like OVS or SRIOV. + - UDP_Replay + :: + The UDP Replay is implemented as a DPDK application using VNF Infrastructure + Library (VIL).
