LDOP-Edge Architecture for Distributed Data Processing and Sharing in E-Government

Abstract

E-government systems use growing volumes of data across agencies and administrative levels. In a fully centralized model, each local request traverses a wide-area network (WAN), which may increase latency, consume bandwidth, and interrupt point-of-service operations during outages. This design paper proposes LDOP-Edge, a governed edge layer integrated with the National Data Platform (NDOP), secure connection points (AGN), local data platforms (LDOP), and authoritative source systems. LDOP distributes machine-enforceable policies for cache eligibility, time-to-live (TTL), permitted degraded-mode operations, access control, retention, synchronization, and evidence logging. Edge Nodes store only approved minimum data and never become authoritative sources. Cached records carry source, version, update time, validity, integrity protection, and verification status. Offline transactions carry event and idempotency identifiers and remain provisional until central validation. The paper contributes a public-sector architecture mapping, a decision matrix for policy-controlled caching, a transaction state machine, a threat-control model, and a reproducible protocol for comparing centralized, simple-cache, and LDOP-Edge configurations. Because the current work is architectural and no measured prototype results are claimed, expected performance and continuity benefits are stated as hypotheses for controlled validation.
