The Spread Toolkit provides tools for developing reliable and robust distributed applications ranging from collaboration tools to fault-tolerant database servers to replicated Web servers. It consists of a daemon which provides multicast messaging, reliability, ordering, and membership services, and a library which applications link with. Spread provides a simple API for writing group applications and is designed to provide high performance for local and wide area networking applications.
Unison is a file-synchronization tool for Unix and Windows. It allows two copies of a collection of files and directories to be stored on different hosts (or different disks on the same host), modified separately, and then brought up to date by propagating the changes in each replica to the other. Unison can deal with updates to both replicas of a distributed directory structure. Updates that do not conflict are propagated automatically. Conflicting updates are detected and displayed. Unison can communicate through a direct socket link or through an rsh/ssh tunnel. It uses network bandwidth efficiently.
Pen is a load balancer for "simple" TCP-based protocols such as HTTP or SMTP. It allows several servers to appear as one to the outside. It automatically detects servers that are down and distributes clients among the available servers. This gives high availability and scalable performance.
Remote Methode Call is a project to enable calls to methods in remote C++ classes. The transport is implemented as a library, and is free from dealing with the internal RMC stuff, so any C/C++ programmer is able to write a transport for his own purpose. RMC(2) currently has a sockets transport library as reference implementation. It is developed on Linux, and supports Linux on iX86 and PPC. RMC should also work on BeOS. Testers and developers are welcome to the project.
GNUnet is a peer-to-peer framework with focus on providing security. All peer-to-peer messages in the network are confidential and authenticated. The framework provides a transport abstraction layer and can currently encapsulate the network traffic in UDP, TCP, HTTP, HTTPS, or direct 802.11 (WLAN). GNUnet supports accounting to provide contributing nodes with better service. The services built on top of the framework include anonymous file sharing and a virtual network providing IPv4-IPv6 transition via protocol translation over the P2P network.
AutoNOC is a high performance, production integrated, peer-to-peer network operations management platform for Windows and Linux. It provides real-time historical analysis, root cause, fault detection, reporting, alerts and alarms, and no-nonsense correlation. It is an interoperable vendor independent solution with built-in support for Microsoft, Cisco, Linux, IBM, and other major technologies. Additionally it offers many novel capabilities, including end user personalization, easy scalability, compressed historical databases, infinite histories, event archiving (it works as a syslog server), and multi-language support.
Platform Independent Petri Net Editor (PIPE) creates and analyses Petri Nets quickly, efficiently, and effectively. A key design feature is the modular approach adopted for analysis, enabling new modules to be written easily and powerfully, using built-in data layer methods for standard calculations. Six analysis modules are provided, including Invariant Analysis, State-Space Analysis (deadlock, etc.), and Simulation Analysis and Classification. PIPE adheres to the XML Petri net standard (PNML). The file format for saving and loading Petri Nets is extensible through the use of XSLT, the default being PNML.
GNU VPE creates a virtual ethernet by creating host-to-host tunnels between multiple endpoints. Unlike other virtual private "network" solutions which merely create a single tunnel, it creates a real network with multiple endpoints. It is designed to be conceptually simple and straightforward to setup (assuming prior IP routing knowledge) without sacrificing flexibility. It is designed to sit on the gateway machines of company branches to connect them, but it can also be used to tunnel into a VPN with a variety of protocols (RAW IP, ICMP, UDP, TCP, HTTPS-Proxy, DNS).
