Abstract: Performance metrics related to the processing and propagation of messages related to select applications are collected during a simulation of a network. Each message associated with an application is tagged, and each simulated packet that contains some or all of a tagged message is correspondingly tagged to facilitate the creation of transmit records and receive records. A post processor is configured to collate transmit and receive records of each tagged message to identify delays associated with each node that processes the message, and each link that propagates the message from node to node within the network. The processed timing information is provided to the user via an interactive user interface that allows the user to view the timing information from an application layer perspective.

Abstract: Generating a user interface for debugging a network simulation based on modeled network behavior by providing a user interface (UI) to depict both of a high level element and a low level element based on the simulation. The high level element may be presented in a hierarchical view representing a hierarchy of elements. The hierarchical view may be provided in a tree-view based on one of a topology or taxonomy of elements within the simulated network or the hierarchy of elements may be based on a simulation hierarchy of elements within the simulated network. An invoking element may be depicted higher in the hierarchical view than an element invoked by the invoking element. Both high and low level commands may be issued from an integrated command line.
