A system for simulating a network includes a request processor operably connected to a simulation engine. The request processor receives a request for network simulation data and input data relating to a topology of a network including node data and relationship data with relationship parameters. The simulation engine outputs a stream of event data based on the relationship data to the request processor and generates respective events by determining a source node and a destination node and corresponding relationship parameters, determining an event time, and determining a transfer value. The simulation engine also, in response to a determination that the transfer value does not exceed a current resource level of the source node, decrements the current resource level of the source node by the transfer value, increments a current resource level of the destination node by the transfer value, generates event data, spawns an event generation process, transmits update data, spawns at least one additional event generation process, and streams the event data to the request processor for transmission to a user device.
