The apparatus includes persistent storage to store raw binary data transformable into messages associated with simulation of the asset, and a random access memory (RAM) to store a protocol name, sender identifier and message type of the messages in respective hash tables. These hash tables further include a fourth hash table that maps times of the messages to the raw binary data in the persistent storage. In response to a request for playback of messages from a selected time, the apparatus locates the raw binary data for a message chronologically last in time before the selected time using the four nested hash tables in the RAM, retrieves the raw binary data for the message from its location in the persistent storage medium, and transforms the raw binary data into the message for presentation."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Simulation of an asset including message playback using nested hash tables","description":"An apparatus is provided for simulation of an asset to train a user to use the asset.
