modules to integrate and synchronise Fast Path processing and Slow Path / Control Plane in a
transparent manner. 6WINDGate SDS delivers the highest possible performance MC
architectures can sustain.
Control Plane Modules are the same for all 6WINDGate Profiles.
6WINDGate EDS/SDS Linux Networking Stacks includes 6WINDGate ADS Linux Networking Stack plus
the Cache Manager module required to synchronise Fast Path processing and Slow Path / Control Plane.
Figure 4 shows how the different 6WINDGate Profiles can be used to offer the required level of
performance according to the number of available cores.

3.3 FAST PATH LESS SOLUTION - 6WINDGATE ADS
6WINDGate ADS (Figure 5) is targeted for low-end applications. Control Plane and Data Plane are colocalized
and the entire 6WINDGate software runs in Linux environment. Forwarding is performed at
the Linux Networking Stack level.
To build this profile, the following 6WINDGate building blocks are required:
• 6WINDGate ADS Linux Networking Stack
• 6WINDGate Control Plane Modules
6WINDGate ADS architecture can be used for single-core processors or MC processors. For MC
architectures, it means that Linux kernel with a dedicated optimized SMP networking stack is running on
all the cores according in order to process many packets simultaneously. 6WINDGate ADS Linux
Networking Stack has been enhanced compared to a standard Linux stack (refer section 4.3).
6WINDGate Control Plane offering is modular and modules can be selected according to requirements.
6WINDGate XML-based Management Plane is provided to deliver a complete solution.
