Abstract

A lost contact policy response system and related method for adjusting the operation of one or more network infrastructure devices upon detection of a loss of contact with a policy server function. The response system includes a policy enforcement function (“PEF”), a policy manager function, and either or both of policy set(s) and policy enforcement rule (“PER”) set(s). The PEF implements stored or generated PER set(s). The policy manager function includes a monitoring function and an analysis function. The monitoring function monitors for continuing connectivity or signal exchange contact with a network policy server function. The analysis function selects a designated policy, policy set, PER or PER set, and instructs the PEF to implement the selected policy, PER or set. The policy and/or PER sets may be pre-installed, updated, re-installed, revised, or otherwise changed when and as desired. The related method includes corresponding steps for implementing the operations of the functions described.
