Patent ID: 7356609

Claim:
An optimized interface for handling non-routed point-to-point (PPP) sessions, comprising: control logic configured to link to an interface module, the interface module having information relating to a client and a PPP session, wherein the interface module is created after the PPP session is established; control logic configured to use the information in the interface module to facilitate communications with the client for duration of the PPP session, wherein the interface module comprises information describing a physical interface associated with the client and the PPP session; and control logic configured to remove the link to the interface module when the PPP session is terminated; and a routing table, wherein the routing table is optimized by including only subnet routes associated with corresponding non-routed PPP sessions, wherein the subnet routes point to the optimized interface; wherein the optimized interface is configured to receive data packets for a client routed to the optimized interface and to forward the data packets to the client over a physical interface corresponding to a linked interface module associated with the client; wherein the client is interfaced to one of a plurality of physical interfaces; and wherein the optimized interface is able to handle communications with the client for the duration of the PPP session regardless of which one of the plurality of physical interfaces the client is interfaced to.
