OPNET Technologies Delivers IP-Service Design and Optimization Solution for Internet, Application Service Providers.Business & High Tech Editors WASHINGTON--(BUSINESS WIRE)--May 1, 2000 Software Helps Reduce Application Response Times by Graphically Identifying Sources of Delay and Predicting Application Performance over Proposed Network Designs OPNET OPNET Operations Network OPNET Olympic Peninsula Narcotics Enforcement Team OPNET Operational New Equipment Training OPNET Optimized Network Evaluation Tool OPNET SMDPS Phase III Operational Network Technologies, Inc., a developer of predictive network-management software, today announced the availability of the Application Characterization Environment (ACE) for IT DecisionGuru 7.0. Paired with IT DecisionGuru, ACE provides application service providers (ASPs) and Internet service providers Internet service provider (ISP) Company that provides Internet connections and services to individuals and organizations. For a monthly fee, ISPs provide computer users with a connection to their site (see data transmission), as well as a log-in name and password. (ISPs) with a virtual proving ground for end-to-end infrastructure design and optimization, with visual auto-analysis of the factors affecting end-user service levels. With IT DecisionGuru, network planners and operations staff can evaluate the performance of existing infrastructures, predict the impact of proposed modifications, and validate new service proposals before committing to a plan of action. IT DecisionGuru data provides ASPs and ISPs with an understanding of key operational parameters, such as network capacity, the interaction of multiple communications protocols Hardware and software standards that govern data transmission between computers. The term "protocol" is very generic and is used for hundreds of different communications methods. A protocol may define the packet structure of the data transmitted or the control commands that manage the , and the actual reliability of "failure-resistant" infrastructures. ACE extends this core capability by enabling service providers to visualize application packet flows in order to understand the root causes of slow response times. If the analyses uncover possible performance issues, ACE proposes remedies automatically. "Businesses and consumers alike expect their application, Internet and hosting services to be as reliable as the public telephone system," said Marc Cohen PERSONAL Marc Cohen lives in the San Fernando Valley and attended Cal State Northridge University He is married with two children. Marc was formerly President of the Starlight Childrens Foundation. , Chairman and CEO (1) (Chief Executive Officer) The highest individual in command of an organization.

"IT DecisionGuru helps ASPs and ISPs meet stringent service-level demands by predicting future performance. Service providers now have the means to conduct proactive planning in an orderly fashion, weighing the price/performance tradeoffs of alternative solutions and validating those solutions under a wide variety of possible conditions." Software That Understands Networks ACE enables service providers to determine how individual applications are likely to perform under a wide range of loading conditions. ACE acquires a "fingerprint" of an application by importing traces from network analyzers A specialized hardware device or software in a desktop or laptop computer that captures packets transmitted in a network for routine inspection and problem detection. Also called a "sniffer," "packet sniffer," "packet analyzer," "traffic analyzer" and "protocol analyzer," the network . ACE graphically breaks down the response time into delays resulting from protocol effects, link throughput, network latency See latency. , processing at each tier (e.g., client, Web server, database server) and inefficient application code. ACE, used in conjunction with ITDG ITDG Intermediate Technology Development Group , can then simulate the performance of that application when deployed over any infrastructure, and forecast end-to-end service performance. This detailed understanding of application performance accelerates problem isolation and simplifies the task of designing or re-designing the network infrastructure. ACE can be used repeatedly on the resulting packet traces from simulations to gain further insight into how the application would perform on the proposed network. AppDoctor(TM), a key feature of ACE, analyzes packet traces and provides an immediate diagnosis of poor application performance. Based on the diagnosis, AppDoctor provides a number of remedies that can be easily explored via simulation. "IP services are growing in importance among many service providers," said Cohen cohen or kohen (Hebrew: “priest”) Jewish priest descended from Zadok (a descendant of Aaron), priest at the First Temple of Jerusalem. The biblical priesthood was hereditary and male. . "AppDoctor offers an advanced capability to help service providers streamline and optimize their offerings by isolating specific, difficult-to-diagnose, application-performance problems. This can reduce time to resolution considerably, minimizing disruptions of service and helping service providers build more cost-effective delivery systems." New Models Strengthen QoS, Application Traffic Simulations IT DecisionGuru 7.0 includes additions to the OPNET Model Library intended to assist service providers in delivering consistent QoS levels. One such example is the ability to build models of specific user types and groups of users. An ASP, for example, could create an accounting-user model or an HR-user model to simulate the type and quantity of network traffic generated by that user community. The result is a realistic usage scenario with which to evaluate the performance of new or modified service proposals. The library has also been expanded with new models for IP quality-of-service specifications CAR, CQ, RED and WRED WRED Weighted Random Early Detection WRED Weighted Random Early Discard WRED Women and Rural Economic Development . In addition to the new QoS models, wireless LAN A local area network that transmits over the air typically in the 2.4 GHz or 5 GHz unlicensed frequency band. It does not require line of sight between sender and receiver. Wireless base stations (access points) are wired to an Ethernet network and transmit a radio frequency over an area and virtual LAN Also called a "VLAN," it is a logical subgroup within a local area network that is created via software rather than manually moving cables in the wiring closet. It combines user stations and network devices into a single unit regardless of the physical LAN segment they are attached to and models have been added to help service providers model and simulate business-critical networks that extend beyond traditional, wired LAN (Local Area Network) A communications network that serves users within a confined geographical area. The "clients" are the user's workstations typically running Windows, although Mac and Linux clients are also used. implementations. About OPNET Technologies, Inc.
