Description
VPP's host stack is a user space implementation of a number of transport, session and application layer protocols that leverages VPP's existing protocol stack. It roughly consists of four major components:
- Session Layer that accepts pluggable transport protocols
- Shared memory mechanisms for pushing data between VPP and applications
- Transport protocol implementations (e.g. TCP, SCTP, UDP)
- Comms Library (VCL) and LD_PRELOAD Library
Applications can link against the following APIs for host-stack service:
- Builtin C API. It can only be used by applications hosted within VPP
- "Raw" session layer API
- VCL API that offers a POSIX-like interface
- POSIX API through LD_PRELOAD
