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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Layer-2 packet return in proxy-router communication protocol environments","description":"A Layer 2 packet return mechanism in a proxy, such as a web cache, operatively associated with a redirecting router.
