Abstract: A traffic generator generates a plurality of traffic flows, with each of the traffic flows being associatable with one or more of a plurality of output interfaces of the traffic generator. In an illustrative embodiment, each of the output interfaces may have any desired combination of the traffic flows associated therewith. The traffic flows may be generated based on user selection of at least one of a protocol encapsulation, a packet size distribution model, a packet arrival time distribution model, a traffic model, and a packet payload description. Information characterizing one or more of the traffic flows may be stored as a traffic file in a memory associated with the traffic generator.

Abstract: A software-based development tool is operative to automatically determine an appropriate simulation configuration for a multistage switch fabric or other multiple circuit element electronic system. The development tool includes an interface permitting user control of one or more configurable parameters of the electronic system, and automatically generates a simulation configuration for the electronic system based on current values of the configurable parameters. The simulation configuration is advantageously generated without requiring further user input, and specifies interconnections between the circuit elements which satisfy the current values of the configurable parameters.

Abstract: A method and apparatus are disclosed for generating a graphical interface for software applications having a command line interface to enable local or remote access of such software applications in a uniform manner without regard to the location of the remote application. The location and syntax of a new software application, and any required environment settings, are specified in response to a sequence of queries. The specifications for each software application is parsed to generate a graphical client interface listing the available software applications and enabling remote access to such software applications. A desired software application is selected by a user from the client interface and the user specifies any necessary parameters for the selected software application. An input file is transferred from the client to the remote server where the selected software application is located. Any output or log files are returned to the client, for example, using the FTP protocol.
