== Description ==
VSAP(VPP Stack Acceleration Project) is to establish an industry user space application ecosystem based on VPP host stack. VSAP is to integrate existing open source projects, e.g.,  Nginx and Envoy, with VPP host stack and plan to upstream if possible. The project will benefit both VPP host stack and the applications. Firstly, VSAP can help stabilize VPP host stack through community effort. Secondly, VSAP aims to performance tuning from both VPP host stack and application side. VSAP will firstly focus on Nginx VPP host stack acceleration, and then cover more projects in the long term.

The initial code is contributed by Intel and Shanghai Jiaotong University. POC code is ready, and we can achieve around 100% RPS improvement for 1KB Nginx requests. Below is the performance test result for reference.

== Scope ==
VSAP's main goal is to adapt existing popular open source projects to work with VPP's host stack and, whenever possible, to upstream such changes to their respective projects. Additionally, VSAP will provide necessary configuration parameters and test scripts to help users easily start from scratch or to automate testing. 
* Integrated/adapt Projects
** Start from Nginx, and will cover more projects such as Envoy, gRPC etc.
* Environment 
** Adapt to all environment such as bare mental, containers and VMs. 
* Performance tuning
** Add CSIT tests
** Find VCL bottlenecks
