The FD.io VPP packet processing pipeline is decomposed into a ‘packet processing
graph’. This modular approach means that anyone can ‘plugin’ new graph
-nodes. This makes VPP easily exensible and means that plugins can be
+nodes. This makes VPP easily extensible and means that plugins can be
customized for specific purposes. VPP is also configurable through it's
Low-Level API.
