The Application Switch sits between applications and service providers, allowing a central location for configuration instead of requiring the user to configure each application separately. The switch also allows mutliple services to be combined and appear as a single service to applications.
Hydro is an independent implementation of ICE, the object-oriented RPC protocol by ZeroC, for the O'Caml programming language. Hydro (like ICE) allows you to bridge language barriers by letting components written in different programming languages communicate with each other. ZeroC's ICE product currently includes implementations for C++, Java, C#, Python, Ruby, VB, and PHP. Hydro adds support for O'Caml. Hydro includes an asynchronous runtime and a generator called hydrogen.
PMS/PyPubSub (short for Python Message Service / Python based Publish Subscribe) is a framework for implementing a publish subscribe mechanism into a Python application. A python process somewhere in the network publishes one or more topics which consist of Python objects. Multiple processes in the network can subscribe to fresh updates of the published topics. A publisher and its subsribers are fully decoupled. The datatype of a topic can be freely defined and changed at runtime. New publishers and subscribers can easily be added at runtime.
TIDorb C++ is a CORBA 2.6 ORB with a high level of stability and performance. It fully implements Portable Object Adapter (POA), IIOP protocol (versions 1.0, 1.1, and 1.2), including bi-directional communications, MIOP protocol (IIOP over udp/multicast), ZIOP (zipped IIOP), SSLIOP (SSL over IIOP), CSIv2, the Dynamic Anys API, DII dynamic invocation interface, and DSI dynamic skeletons APIs, the static invocation API, OBV (object by value passing), and some CORBA messaging QoS policies, and it partially implements RealTime functionalities and Codecs.
The Simple components for Ada library provides implementations of smart pointers for automatically collected objects (using reference counting), object persistence, unbounded and bounded arrays of smart pointers, generic unbounded arrays of private objects and plain pointers, generic sets, maps, directed graphs, directed weighted graphs, stacks, and storage pools. It also includes table management, string editing, IEEE 754 support, and infix expression parsing tools. Implementations of some lock-free shared data structures are provided.
TAO is a standards-compliant, real-time implementation of CORBA that provides efficient, predictable, and scalable quality of service (QoS) end-to-end. Unlike conventional implementations of CORBA, which are inefficient, unpredictable, non-scalable, and often non-portable, TAO applies the best software practices and patterns to automate the delivery of high-performance and real-time QoS to distributed applications.
xmlrpc-c is a programming library for writing an XML-RPC server or client in C or C++. XML-RPC is a standard network protocol to allow a client program to make a simple remote procedure call (RPC) type request of a server. It's like SOAP or CORBA, but much simpler. This library speaks the same XML-RPC as similar libraries for lots of other programming languages, with most of the popular extensions. The client library uses either w3c libwww or Curl for HTTP. The server library contains a complete lightweight HTTP (Web) server and also facilities for running with CGI under any Web server.
