Abstract

Massive Open Online Courses (MOOCs) have made education easily accessible, but the inter-university credit transfer process that is both scalable and policy compliant is difficult to implement. This research work presents a novel DFA-based Policy Validation in BGP-Routed Credit Transfer Networks approach using BGP-based routing combined with DFA-based policy validation. Here, Universities will be treated as autonomous systems forming part of a distributed academic federation system, where routing identifies optimal routes for credit transfer based on course equivalency and credit weight. A multi-stage DFA engine checks the satisfaction of prerequisites, accreditation compliance, and credit equivalence. JDBC-SQL integration along with two-phase commit mechanism is used to maintain database consistency. The proposed implementation using Java, MySQL, JDBC, ANTLR4, and FRR was tested on 100 interconnected university nodes. It showed 96.3% of validation efficiency, 99.7% of transaction consistency, 23.4 ms average latency, and 812 requests per second, which indicates superior performance of the proposed method against the traditional centralized and blockchain-based methods.
