The specialized networking and application system includes an enforcer configured to intercept the signaling messages and select an optimal SGW, PGW, SMF/UPF and application servers in real time. More specifically, the enforcer intercepts and generates GSM MAP, Diameter, GTP-C and HTTP2/JSON signaling messages. The enforcer executes a policy to force the user devices to re-establish the data connection, thus anchoring at different SGW, PGW, SMF/UPF and application server to keep end-to-end routing path optimal, when the impacting factor changes. The enforcer can further feed its performance data and decision matrix into the analyzer and database to further optimize the decision process. Analyzer and KPI metrics databases are installed at central data centers to collect the KPI data from different probes and enforcer, calculate in real-time the optimal routing path with different decision factors considered, and interact with enforcer to update the latest optimal path status based on the data collected.
