OPNET Technologies, Inc.

OPNET Modeler is the industry’s leading environment for network modeling and simulation, allowing you to design and study communication networks, devices, protocols, and applications with unmatched flexibility and scalability. Modeler is used by the world’s most prestigious technology organizations to accelerate the R&D process. Modeler’s object-oriented modeling approach and graphical editors mirror the structure of actual networks and network components, so your system intuitively maps to your model. Modeler supports all network types and technologies, allowing you to answer the most difficult questions with confidence.

Using OPNET Modeler, your organization will benefit by: Boosting Network R&D Productivity: Leverage the specialized editors, analysis tools, and off-the-shelf models provided with Modeler to focus your time on the unique parts of your project. Improving Product Quality: Test technology or network designs in realistic scenarios before production. Reducing Time-to-Market: Develop and validate your designs ahead of the competition. Use your models to demonstrate the value of your approach to management, partners, and customers.

Modeler Key Features Originally developed at MIT, and introduced in 1987 as the first commercial network simulator, OPNET Modeler continues to define the state of the art with the following features:

Most scalable and efficient simulation engine, enabling the fastest simulation runtimes using advanced acceleration techniques for wired and wireless models. For example, simulate thousands of wireless nodes in a terrainrich environment, with dynamic application and routing behavior, at faster-than-realtime speed on standard workstations. Hierarchical network models Manage complex network topologies with unlimited subnetwork nesting. Object-oriented modeling Nodes and protocols are modeled as classes with inheritance and specialization. Clear and simple modeling paradigm Model the behavior of individual objects at the “Process Level” and interconnect them to form devices at the "Node Level;" interconnect devices using links to form networks at the "Network Level." Organize multiple network scenarios into “Projects” to compare designs. Finite state machine modeling of protocols and other processes. Simulate any required behavior with C/C++ logic in FSM states and transitions. You control the level of detail.

Comprehensive support for protocol programming. Over 400 library functions simplify writing protocol models. Wireless, point-to-point, and multipoint links Link behavior is open and programmable. Accurately account for delay, availability, bit errors, and throughput characteristics of links. Incorporate physical layer characteristics and environmental effects using a library that includes enhanced TIREM, Longley-Rice, and Free Space, or interface with custom propagation models. Most advanced modeling platform, with highly optimized sequential and fully parallel discrete event simulation, hybrid and analytical simulation, as well as HLA and co-simulation technologies. Total openness APIs for program-driven construction or inspection of all models and result files. Easily integrate existing code libraries into your simulations. Source code provided for all standard models. Users can encrypt models to protect intellectual property. Integrated debugger Quickly validate simulation behavior or track down problems.

OPNET Modeler is based on a series of hierarchical editors that directly parallel the structure of real networks, equipment, and protocols. Network model

The Project Editor graphically represents the topology of a communications network. Networks consist of node and link objects, configurable via dialog boxes. Drag and drop nodes and links from the editor's object palettes to build the network, or use import and rapid object deployment features. Use objects from OPNET's extensive Model Library, or customize palettes to contain your own node and link models. The Project Editor provides geographical context, with physical characteristics reflected appropriately in simulation of both wired and mobile/wireless networks. Use the protocol menu to quickly configure protocols and activate protocol specific views. The Node Editor captures the architecture of a network device or system by depicting the flow of data between functional elements, called "modules." Each module can generate, send, and receive packets from other modules to per form its function within the node. Modules typically represent applications, protocol layers, algorithms and physical resources, such as buffers, ports, and buses. Modules are assigned process models (developed in the Process Editor) to achieve any required behavior. The Process Editor uses a powerful finite state machine (FSM) approach to support specification, at any level of detail, of protocols, resources, applications, algorithms, and queuing policies. States and transitions graphically define the progression of a process in response to events. Each state of a process model contains C/C++ code, supported by an extensive library of functions designed for protocol programming. Each FSM can define private state variables and can make calls to code in user-provided libraries. FSMs are dynamic and can be spawned (by other FSMs) during simulation in response to specific events. Dynamic FSMs dramatically simplify specification of protocols that manage a scalable number of resources or sessions, such as TCP or ATM. Use the Process Editor to develop entirely new process models, or use the models in OPNET Technologies’ Model Library as a starting point. OPNET’s process modeling framework supports full multithreading and use of parallel computing architectures.

Integrated analysis tools Comprehensive tools to display simulation results. Easily plot and analyze time series, histograms, probability functions, parametric curves, and confidence intervals. Export to spreadsheets or use XML. Animation Animate model behavior, either during or after simulation, and graphically monitor statistic values during simulation execution. Leverage interfaces for 3D visualization. Import data from text files, XML, and popular tools from Cisco, HP, NetScout, BMC, Concord, Sniffer, Infovista, MRTG, cflowd, tcpdump, and others. Financial cost attribute for devices Export network costs to spreadsheets for a financial bottom line. Comprehensive library of detailed protocol and application models… Including Multi-Tier Applications, Voice, HTTP, TCP, IP, OSPF, BGP, EIGRP, RIP, RSVP, Frame Relay, FDDI, Ethernet, ATM, 802.11 Wireless LANs, MPLS, PNNI, DOCSIS, UMTS, IP Multicast, Circuit Switch, MANET, Mobile IP, IS-IS, and many more. Provided as FSMs with open source code.
