Policy based routing system and method for caching and VPN tunneling
First Claim
1. A system for redirecting network traffic to a target route comprising:
- a public network regional router for routing data packets according to a gateway routing protocol;
a router interface device dedicated to an enterprise, the router interface device comprising;
an interface for sending and receiving a data packet to and from the public network regional router wherein the public network regional router routes-data packets destined for the enterprise network to the router interface device; and
logic for redirecting the data packet via the target route to a special purpose data packet device, wherein the special purpose data packet device comprises;
communication logic for sending and receiving a data packet to and from the router interface device;
logic for analyzing and modifying the data packet;
logic for inserting policy based management instruction within the public network regional router; and
logic for processing the data packet for one hop delivery wherein the policy based management instruction supersedes the gateway routing protocol.

Abstract
An enterprise network router interface communicates with a public regional Autonomous System Border Router (ASBR). The ASBR only forwards the enterprise network traffic to the router interface. The router interface redirects data packets to data highly specialized packet processing appliances for parallel processing of VPN and cache application traffic. Policy based routing instructions are imposed on the ASBR for subsequent secure, tunneled transmission. This enterprise routing system and method used within an enterprise imposes routing instructions superseding gateway protocol routing thus allowing VPN and content caching applications to be run efficiently and securely without resort to an enterprise dedicated backbone.
