Abstract
In general, techniques are described for decentralizing handling of subscriber sessions within a gateway device of a mobile network. A mobile network gateway comprises a data plane having a plurality of forwarding components to receive session requests from a mobile service provider network in which the mobile network gateway resides. A control plane comprises a plurality of distributed subscriber management service units coupled by a switch fabric to the data plane. Each of the subscriber management service units serve as anchors for communication sessions for mobile devices that are accessing one or more packet data network by the mobile service provider network. A request delegation module within each of the forwarding components directs the session requests to the subscriber management service units unit to provide management services for the sessions requested by the mobile device.
