Hardware acceleration for unified IPSec and L2TP with IPSec processing in a device that integrates wired and wireless LAN, L2 and L3 switching functionality

摘要

An apparatus provides an integrated single chip solution to solve a multitude of WLAN problems, and especially Switching/Bridging, and Security. In accordance with an aspect of the invention, the apparatus is able to terminate secured tunneled IPSec and L2TP with IPSec traffic. In accordance with a further aspect of the invention, the architecture can handle both tunneled and non-tunneled traffic at line rate, and manage both types of traffic in a unified fashion. The architecture is such that it not only resolves the problems pertinent to WLAN, it is also scalable and useful for building a number of useful networking products that fulfill enterprise security and all possible combinations of wired and wireless networking needs.
