| 4 | The Vector Packet Processor (VPP) |
| 5 | ================================= |
| 6 | |
| 7 | This section describes some of the core concepts and features of FD.io VPP. |
| 8 | |
| 9 | To start with FD.io VPP uses a technique called Vector Packet Processing. |
| 10 | This gives FD.io VPP a siginficant performance improvement over packet |
| 11 | processing applications that use scalar processing. |
| 12 | |
| 13 | Also, At the heart of Fd.io VPP's modular design is a 'Packet Processing Graph'. |
| 14 | This makes FD.io VPP scalable and easily extensible. |
| 15 | |
| 16 | The FD.io software also includes a feature rich network stack. This includes |
| 17 | a TCP host stack that utilizes VPP’s graph based forwarding model and vectorized |
| 18 | packet processing. |
| 19 | |
| 20 | FD.io VPP is tested nightly for functionality and performance with the |
| 21 | CSIT project. |
