Methods and systems to split equipment control between local and remote processing units

Abstract

Techniques for distributing computation and storage tasks between customer premises equipment and a remote vendor computer are disclosed. The techniques include receiving, at a customer premises computer equipment, a TCP-based data flow from a client, rewriting the IP header of the TCP-based data flow, and forwarding the TCP-based data flow to a defined TCP port. The techniques also include a transient termination server process operating in user space of the customer premises equipment to read an application payload sent by the client and sending data to a deep packet inspection engine for classification. The techniques may include identifying, from the client data flow, a protocol associated with the data flow, looking up a handling policy from a policy cache stored in the customer premises equipment, and handling the data flow according to the handling policy.
