6WINDGate - Architecture Overview NE 6W-08-188 v1.0
6WINDGate Fast Path Modules implement a large set of networking features for MC.
Model v1.1
Page 24
To achieve the highest level of performance, these modules can run in the MCEE (6WINDGate SDS).
Thus they are therefore independent from the selected Operating System.
Fast Path Modules can also be implemented as Linux kernel modules located between the drivers and the
Linux Networking Stack (6WINDGate EDS). This solution is well-suited for small MC configurations or if
no specific MCEE is available for the selected MC (refer section 3.5).
For each networking feature, a 6WINDGate Fast Path Module has been designed, having in mind the
following design rules:
• Fast Path Module shall be simple and efficient,
• Fast Path Module shall be easily integrated with a Linux-based Slow Path and Control Plane
through simple APIs,
• Fast Path Module shall be portable.
The following 6WINDGate Fast Path Modules have been developed:
• Fast Path – IPv4 Forwarding (This module includes the Fast Path Manager module, refer section
5.3)
• Fast Path – IPsec
• Fast Path – L2 (This module is based on VNB framework, refer section 4.3.1)
• Fast Path – QoS
• Fast Path – Reassembly
• Fast Path – NAT & Filtering
• Fast Path – IPv6 Forwarding and Transition
• Fast Path – ROHC
• Fast-Path – IPv4 Multicast
• Fast-Path – IPv6 Multicast
• Fast Path – TCP Offload
To scale on distributed architectures, 6WINDGate Fast Path also includes a specific module:
• Fast Path – Multi-instance
