Abstract

A device for processing network access requests responsive to more than one network access protocol comprises a protocol layer responsive to a client access request based on a first protocol, a gateway layer in communication with the protocol layer including at least one protocol handler for processing access requests and a state manager having more than one set of process states required for each network access method, and an inbound filter state object in communication with the gateway layer that is responsive to at least one protocol handler and is invoked to filter attribute data in the access request packets. A method for dynamic, scaleable attribute filtering in a multiple-protocol compatible network access environment comprises receiving an access request which is based upon a first supported network access protocol, processing the access request as a task, processing the task at a protocol handler to verify user identity; checking the access request at the protocol handler for an inbound filter attribute, retrieving a state interface pointer from a state manager based upon an inbound filter being found in the access request and invoking an inbound filter state object to filter the first access request in accordance with the first state interface pointer.
