The main goal of Linux Layer7 Switching is to
provide a fast framework for Layer 7 switching.
Layer 7 switching is driving a low-level engine
using networking design to speed up forwarding of
the data stream. The implementation in this
project is split into a userspace daemon and a
low-level kernelspace forwarding engine. The
userspace daemon is responsible for scheduling and
switching decisions. The kernelspace forwarding
engine is responsible for forwarding the stream
and using a TCP splicing scheme. TCP splicing is
the postponement of the connection between the
client and the server in order to obtain
sufficient information to make a routing decision.
