Abstract:
A Layer 2 packet return mechanism in a proxy, such as a web cache, operatively associated with a redirecting router. In a particular embodiment, the present invention provides a Layer 2 packet return mechanism in a Web Cache Communication Protocol (WCCP) network environment. In one embodiment, the present invention provides an efficient mechanism allowing a proxy or web cache to recognize WCCP redirected packets, forwarded using Layer 2 forwarding mechanisms, and subsequently to return unprocessed packets to the original forwarding WCCP router using a Layer 2 packet return mechanism.
