The Arakhnê.org Network Editor (NetEditor) is a Java component that permits you to edit and show connected graphs. The graph defines the constructs of a visual language, and NetEditor is able to render associated figures. NetEditor is based on a metamodel composed of the node, edge, and anchor (or ports) constructs. It has a strong separation of the visual-language constructs and the drawings. It provides tools to code graph-drawing layout algorithms. Two algorithms are provided: Ganswer-Sugiyama and Coulomb-Hooke force-based algorithms. Standard UI features are provided: graphical editing of the graph structure, depth levels for nodes and edges, undo, and redo, clipboard, and drag and drop management. The NetEditor API is able to export the graphs to GIF, JPEG, PNG, BMP, SVG, PDF, EPS, PDF, Graphviz DOT, GXL and GraphML. The document file formats used by NetEditor are GXL, GraphML, or NGR files (zipped GXL/GraphML).
JASocket is a lock-free, scalable, and robust server framework with no single point of failure. Servers are run on a cluster of nodes. Servers interact with other servers using mobile agents, which reduces the number of messages and thus reduces the overall system latency. Administration is handled via ssh.
Java Gearman Service is a Java implementation of the gearman service, which provides a generic application framework that farms work out to other machines or processes that are better suited to do the work. It allows you to do work in parallel, to load balance processing, and to call functions in other languages. It can be used in a variety of applications, from high-availability Web sites to the transport of database replication events.
JAConfig implements an eventually consistent distributed key/value database for managing a JASocket cluster. Also included are Quarum for tracking when a quorum of hosts is present, Ranker for determining which nodes are least loaded, ClusterManager for starting up other servers, and Kingmaker, which decides which node is to run ClusterManager. JAConfig is lock-free, actor-based, and has no single point of failure.
Unlike other Java to Objective-C solutions, Java-Objective-C Bridge doesn't require any code generation of class stubs. It allows you to use any Objective-C libraries and frameworks from Java without having to write any native code. In addition to being able to use Objective-C objects, it allows you to pass Java objects to the objective-c runtime as delegates, so that you can write an entire Cocoa application in Java. The bridge provides 3 levels of abstraction. At the lowest level, it provides wrappers around the Objective-C runtime functions. At a slightly higher level of abstraction, it provides a procedural API to send messages to the Objective-C runtime. At the highest level of abstraction, it provides a Proxy class that serves as a wrapper around any Objective-C object that allows you to work with it in Java almost the same as if you were in Objective-C.
MuLaNEO implements algorithms to design and provision resilient multi-layer networks, or hierarchies of technologies (IP/MPLS, Carrier Ethernet, SDH/SONET, etc.). It includes modelling of these technologies, visualizes their interrelations, and allows the dynamic provisioning of the resulting networks on the basis of path computation elements (PCE).
