Block-oriented network simulator (BONeS)

Provides an overview of the BONeS network modelling philosophy and structure. BONeS can be viewed as an integrated system that provides a complete graphical environment for the description and simulation of communications networks. The integrated environment of BONeS includes the capability to describe protocol functions, layers of the ISO Open Systems Interconnection model, and network transmission effects in a hierarchical fashion using block diagrams; configure and execute a discrete-event simulation of the network; perform design iterations; and analyze the system performance. Each of these capabilities is provided through a consistent user interface that relies on the extensive use of graphics, windows, and consistency checking to provide a visual environment for describing networks and their protocols
