....parts 3 of the ORB architecture have seen huge changes. The core development team did not fear applying these huge changes. Examples of where the team showed courage are: Reimplementing the TAO Real time Event Service . Restructuring the ORB Core [6] Adding support for pluggable protocols [7] . Large refactorings on the code generation for implied IDL [8] A good development process supports courage; you can always easily step back from something that proved to not work. Furthermore, a good development process is well defined and documented yet adaptable. We discuss development ....

....of machines using TCP IP. The messaging protocol for CORBA is specified by General Inter ORB Protocol (GIOP) which is a family of protocols that define standard message types and formats. The methods supporting the GIOP messaging protocol can be a significant contributor to memory footprint size [8]. A time and space efficient implementation of GIOP messaging protocols is therefore desirable to reduce footprint without unduly affecting operational throughput between ORB endsystems. This paper discusses the design and performance of dynamically configurable GIOP messaging protocols for an ....

.... also have been explicitly designed using patterns like Virtual Component [11] Acceptor Connector, and Active Object [19] CORBA pluggable protocol frameworks: The architecture of ZEN s pluggable GIOP messaging framework is based on ideas learned from the pluggable protocol frameworks used in TAO [8]. TAO s GIOP messaging is implemented in the monolithic design and therefore each message type marshaler demarshaler consumes memory footprint whether or not they are needed and used by an application. By extensive application of the Virtual Component pattern, we improved the design of GIOP ....

Our prior research on CORBA middleware has explored the efficiency, predictability, scalability and dependability aspects of ORB endsystem design, including static [25] and dynamic [26] scheduling, event processing [9] I O subsystem [27] and pluggable protocol [28] integration, synchronous [29] and asynchronous [30] ORB Core architectures, systematic benchmarking of multiple ORBs [31] and optimization principle patterns for ORB performance [32] This paper extends our previous work by focusing on the following dimensions in the ORB endsystem design space: ....

....that work together to enhance the reliability of an application through both active and passive replication. The DOORS [16] framework described in this paper is another example of a service based approach to fault tolerance. Our recent work on DOORS [17, 18] and TAO s pluggable protocols framework [28] has focused on a service strategy that also allows application developers to select the protocol(s) used to communicate between collaborating ORB endsystems. The CORBA specification defines a standard transport protocol, IIOP, which runs atop TCP. There are many use cases, however, particularly ....

.... protocols and (2) produce a minimal footprint, fault tolerant ORB that can be embedded in network elements, as described in the following steps: Step 1: Define IDL interfaces that map application level QoS requirements to underlying network and platform mechanisms, using pluggable protocols [8] as an enabling technology. Step 2: Make TAO comply to the Minimum CORBA specification [12] and embed it in the network elements as an agent, as well as on client hosts and the signaling processors to provide an open network element management and control framework for high speed networks, such ....

Task 3: Port TAO to a Cisco Network Element and Implement an Optimal IOP Activities: In this task, we will embed TAO in a Cisco network element and integrate the features from Task 2 using TAO s pluggable protocols framework [8]. The specific steps involved in this task include the following: Step 1 Network element evaluation: This step involves the following three activities: 1. Acquire Cisco network element hardware software and verify operation in our environment. 2. Evaluate the configurability of the network ....
