(OCI) announces the availability of commercial products for The ACE ORB (TAO), an open source, real time, high performance, implementation of CORBA 2.2. The popular open source Linux operating system is among the platforms supported. St. Louis Mo. September 30, 1999:OCI announced today that it is accepting orders for immediate shipment of CD-ROMs and documentation kits for TAO. This highly rated object request broker (ORB) has been developed over the last few years to meet the challenging needs of high-performance and real-time distributed applications. It already has a large user base, and this is expected to expand rapidly as OCI's commercial support model is implemented. The hallmark of TAO is its conformance to standards, superior efficiency, predictability scalability, wide platform support and absence of license fees. Many of TAO's hundreds of users have been reluctant to progress beyond the evaluation stage until they could be sure of quality commercial support. This announcement meets that need. OCI's E-Commerce site at www.theaceorb.com offers easy and fast ordering for customers from around the world. Dr. Moshiri the CEO of OCI commented that since OCI decided to support TAO as an open source product several months ago there has been an explosion of interest. "This is an exceptional time to enter the market with product," he said. "Standards based, open source middleware can do a lot towards encouraging open systems, especially in the case of TAO, which has undergone extensive use and testing by industry. OCI has been developing infrastructure software for large distributed OO applications since 1993. This is a natural extension to our core competencies." About TAO and ACE TAO, an open source implementation of the Object Management Group's (OMG) Common Object Request Broker Architecture (CORBA) specification, was developed by the Distributed Object Computing (DOC) Group at Washington University in St. Louis under the direction of Dr. Douglas Schmidt. Dr. Schmidt is an internationally recognized expert in patterns and framework components for real-time middleware. Version 1.0 of TAO is designed to be compliant with CORBA 2.2 and includes some aspects of CORBA 2.3. Although initially targeted for real-time environments, TAO is also well suited for general purpose environments where TAO provides better, more consistent performance than the traditional "best effort" service of other ORBs. Thus, all applications can benefit from the same characteristics that make TAO attractive for real-time developers. TAO's second generation ORB design, with its up front consideration of real-time requirements, is particularly well suited for use in demanding environments. Such considerations must include: avoiding end-to-end priority inversion; maintaining upper bounds on latency and jitter; and providing bandwidth guarantees. These combine to ensure predictable behavior. TAO enables applications to obtain specified levels of what is called Quality of Service (QoS). In addition, because TAO is flexible and open source, it is also suitable for embedded application environments that typically demand small footprint and low cost, as well as good performance. Traditionally, the barrier to viable real-time CORBA has been that many real-time challenges are associated with end-to-end system design aspects. Challenges that transcend the layering boundaries traditionally associated with CORBA. TAO's design provides for the integration of network interfaces, OS I/O subsystems, ORB, and middleware services, in order to provide an end-to-end solution, should the developer require it. TAO, by virtue of the underlying ACE (ADAPTIVE Communications Environment) C++ framework, supports a wide range of platforms and operating systems. ACE is a pioneering open source middleware framework that provides a rich set of reusable C++ wrapper fašades and components that encapsulate common communication software tasks across many OS platforms. ACE provides TAO with exceptional extensibility and the ability to span many platforms. ACE mitigates the maintenance issues that normally arise when trying to support multiple diverse operating system environments. ACE is a critical layer in TAO's ladder of abstraction between the implementation of the specifics of operating and communication systems and the high level of abstraction afforded by CORBA. By leveraging ACE's abstraction layer at the systems level, TAO's design is platform neutral and devoid of the architectural biases that follow when the ORB design is targeted to specific operating systems. Supported Platforms TAO runs on most major platforms, such as UNIX vendor variants and Win 32. (It even runs on MVS Open Edition.). TAO also runs on Linux, FreeBSD and NetBSD UNIX, all of which are free and provide developers with unusually cost-effective options. Distributed applications written using CORBA are usually easier to move from platform to platform. For real time environments TAO supports the major RTOSs such as Lynx, VxWorks, and Chorus ClassiX (from Sun). It is presently being tested on WindowsCE, the operating system targeted at portable consumer embedded products. OCI's initial double disk distribution on CD-ROM covers HP-UX, Solaris on both SPARC and Intel, Linux and NT on Intel. It includes all source code, test cases, examples, benchmark code, and an IDL compiler, as well as binaries for various build configurations for the platforms noted. The distribution features an easy to use installation program that enables routine installations in10 to 20 minutes. Documentation Set TAO is a feature rich ORB providing seven standard CORBA services and two additional services specifically designed to meet those real time needs that are not currently addressed in the CORBA specification. Developers will find they can now take full advantage of these features with this extensive documentation package. Users who are familiar with CORBA will find getting started with the TAO quite easy. As they begin to understand TAO's depth and configurability, they will appreciate its conformance to the CORBA standard and its ability to address complex performance and scalability issues.
