SIGAR (System Information Gatherer and Reporter) is a cross-platform, cross-language library and command-line tool for accessing operating system and hardware level information in Java, Perl and .NET.

Nepxion Discovery is a solution for Spring Cloud with blue green, gray, route, blacklist, limitation, circuit breaker, degrade, isolation, monitor, tracing, dye, failover, async agent. Only one or more services are upgraded at a time, the upgrade is completed and monitored and observed, and this process is performed continuously until all the old versions in the cluster are upgraded to the new version. In the process of stopping the old version, it is impossible to accurately calculate whether the old version has completed the work it is performing, and it needs to be judged by the business itself. Full-link custom gateways, service filters, and load balancing strategies trigger blue-green grayscale release. Full link local and remote, local and global non-parameterized rule-driven strategy. Full-link blue-green-gray release scheduling modeling and traffic detection.

A software toolkit for using the EPCglobal Low Level Reader Protocol (LLRP) to communicate with conforming RFID readers.

JPPF makes it easy to parallelize computationally intensive tasks and execute them on a Grid.

RealPeer is a Java framework for the simulation-based development of P2P systems. Utilising this framework a developer can build a P2P application that can be both: executed as a simulation model and as a real P2P application on a real network.

The purpose of the project is to develop a portable programming framework that facilitates distributed and multi-threaded programming for C++, Java, and Python. MADARA was originally developed as an agent-based middleware specifically for real-time, distributed artificial intelligence, but is now more general purpose for distributed timing, control, knowledge and reasoning, and quality-of-service. MADARA is composed of several tools and middleware, and the main entry point into the system is the Knowledge and Reasoning Language (KaRL) Engine, which provides a real-time scripting language for nanosecond execution times hooked into a flexible transport layer for distributed reasoning. The KaRL engine also supports object-oriented C++, Java, and Python programming through Containers, classes that provide abstractions and references for variable location within the KaRL Knowledge Base. This project is currently in process of being ported from http://madara.googlecode.com.

QuickServer is an open source Java library/framework for quick creation of robust and multi-threaded, multi-client TCP server applications. With QuickServer one can just concentrate on just the application logic/protocol on hand.

Calimero is a Java library for embedded/workstation-based KNX applications. The minimum JVM requirements are either Java ME/CDC 1.4 (Foundation Profile), or Java SE 8 (profile compact1). The library provides remote access and control, supporting KNXnet/IP, KNX IP, FT1.2, TP-UART, and KNX USB. Data exchange is supported on link layer using EMI 1/2 and cEMI, KNX data point types, application/management layer, as well as message buffering.

DotNetOpenServer SDK is an open source lightweight fully extendable TCP socket client/server application framework enabling developers to create highly efficient, fast, secure and robust cloud based smart mobile device and desktop applications. Why? Unlike most application server frameworks, which are implemented over slow inefficient stateless protocols such as HTTP, REST and SOAP that use bulky ASCII data formats such as JSON and XML, DotNetOpenServer has been built from the ground up with highly efficient stateful binary protocols.

DNA is an open, flexible and extensible deep network analyzer software server and software architecture for gathering and analyzing network packets, network sessions and applications protocols, passively off enterprise class networks.

The Plugin Framework for Java is a distributed Plugin framework. It will enable users to write distributed application by just writing simple Plugins. It will come with Plugin clustering, central plugin registry and load balancing.

SAP-JCO Support is a mapping framework for Java applications requiring SAP access. You can easily define your SAP BAPI call in XML and map the SAP fields to java value object fields. Included features are SearchHelp support and an SQL-ish query language.

!EOF is not EOF. EOF is an acronym for Easy Open Framework. The framework offers a flexible but simple client/server fundament for variable network applications. Goal ist creating a really easy to use but hopefully even potent framework like others.

Apache Dubbo is a high performance, lightweight, open source RPC framework written in Java. It offers three key functionalities: interface based remote call, load balancing and fault tolerance, and automatic service registration and discovery. Apache Dubbo is built to support multiple service registries and load balancing strategies right out of the box. Due to its micro-kernel and plugin design it can also be easily extended through third-party implementations. Plenty of companies are using Dubbo, and are helping to continually improve it through Dubbo’s improvement initiative, “Wanted: who’s using dubbo”.

Argus is a JMX browser and instrument panel viewer designed for the Argos project. Argus is however a generic JMX browser and will work with all JMX enabled systems.

Bonswing is a library/framework that uses Java Swing components to list updates to services in the network using Apple's Bonjour. By using Bonswing components, the developer does not have to worry about service discovery and can focus on the application

Alternative implementation of Spring framework remoting subsystem that supports different schemes of remote communication between client and server (1-1, 1-many, dynamic services discovering).

Distributed Computing Over P2P Networks(DisCo) is focused to provide a java framework for programmers to develop distributed software application with lesser or no time spent on distributed computing part.

Etch is a cross-platform, language- and transport-independent framework for building and consuming network services. With Etch, service development and consumption becomes no more difficult than library development and consumption.

GroundWork Foundation is an IT management data abstraction layer and development platform.The Foundation data model allows the integration of any state, event, and performance data running in a Web container.It comes with an XML enabled feeder framework.

Helen provides a Java Programming Language framework for generating UDP network traffic and a standard format for that traffic.

Hermes is a P2P middleware. It's not a framework, but it's a shell over the existing frameworks. This shell is made in such a fashion that it's possible to the app developer to change the underlying framework without any changes to his app code.

btp2p stands for Bluetooth p2p and it is a collection of java classes for p2p networks over Bluetooth. Useful for CLDC multiplayer games and other applications with extendable design for layered protocols. HuNt is a chatroom midlet based on btp2p.
