JXTA technology is a set of open protocols that allow any connected device on the network ranging from cell phones and wireless PDAs to PCs and servers to communicate and collaborate in a P2P manner. JXTA peers create a virtual network where any peer can interact with other peers and resources directly even when some of the peers and resources are behind firewalls and NATs or are on different network transports. The project goals are interoperability across different peer-to-peer systems and communities, platform independence, multiple/diverse languages, systems, and networks, and ubiquity: every device with a digital heartbeat.
UPNPLib is a Java library for the UPNP protocol. It features an easy programming interface for developers as well as an HTTP-based console for end users or developers, so that they can control the UPNP devices residing on their network. It implements all UPNP features like discovery and eventing. The library also provides integration with JMX management (by exposing UPNP devices as MBeans) and RMI through transparent NAT/firewall traversal.
State is a suite of tools for monitoring a network of machines. You tell State how your network looks and should behave, and State warns you when things start to deviate from that rhythm. Many different aspects of a network can be monitored, from disk space and load average to machine connectivity and service availability.
apt-got is a customizable mirror engine. It works like a highly specialized proxy. It employs several pluggable modules that are customized for specific jobs. The first available module builds and supervises a partial (or full) Debian mirror which is populated on-the-fly by apt-get requests. There is also a simple mirror module that can be used to mirror source directories or even (static) Web pages. For increased performance on already-cached files, it employes its own Apache module. It supports customized mirroring algorithms.
mod_backhand is a load balancing module for Apache. It provides per-request HTTP redirection within a heterogeneous Apache server cluster. Each request is processed and run through a set of "candidacy functions" to determine which server is best suited to respond. The request is then proxied to that server. Facilities are in place to allow you to write your own dynamically loadable decision making algorithms. Everything about the request and the current availability of resources can be used in the decision-making process.
LogiTest is a Java application for functional and regression testing of Web sites. It currently supports GET and POST methods, HTTPS, cookies, browser history, XML formatted tests, simple Testlet API for writing new tests, user-defined HTTP headers and parameters, and regular expressions. Tests are recorded and played back through a easy-to-use GUI and can be stored and loaded from XML files.
