Abstract
Methods, systems, and computer products facilitate access to historical data via a real-time tunnel within an architectural framework that encompasses an operational technology (OT) network, a de-militarized zone (DMZ), and an information technology (IT) network. Real-time data is retrieved from a data source using a first connector, which comprises a first tunneler, a first history-writer, and a first history-tunneler. The mechanisms involve interleaving real-time data and historical data over a first tunnel connection, a first firewall, and a second firewall by (a) executing pull replication of the historical data, (b) daisy-chaining the historical data, or (c) a combination of both (a) and (b). The first tunnel connection is established from the first tunneler to a first DMZ tunneler by an outbound connection request from the OT network including the first tunneler to the DMZ including the first DMZ tunneler.
