Abstract:
Methods, apparatuses, and systems are presented for conducting a point-to-point (PPP) session relating to establishing a PPP session involving at least a local node and a remote node, wherein the local node comprises a data plane for handling transfer of data for the PPP session at the local node, and wherein the local node comprises a first control plane for controlling operations of the data plane, replicating at least one portion of information accessed by the first control plane, such that the at least one portion of information may be accessed by a second control plane, and switching from the first control plane to the second control plane, such that the second control plane controls operations of the data plane, wherein the second control plane accesses the at least one portion of information replicated from the first control plane, wherein the data plane is capable of continuing to handle transfer of data for the PPP session during switching from the first control plane to the second control plane.
