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.
netscript is a portable/multi-platform, lightweight TCP/UDP socket scripting system. It is intended to automate situations, built on a word-to-word ruleset response system. It includes wildcard support, character replacement, random replacement, argument inclusion, server timeout, initial send, display altering, multiple character dump formats, telnet protocol support, logging, program to socket dumping, executable ruleset support, reverse binding, module support, data truncation, data formatting, permission options, virtual hosting support, history storage, dynamic storage variables, directory placement, character omitting, timed rules, background support, syslog support, routing support, socket options, interactive mode, and graphical user interface support.
uvlan is a User-space Virtual Local Area Network. In other words, uvlan peers act as nodes on a network switch. Ethernet traffic is routed between peers intelligently. This allows for multiple networks to share resources and even IP address space. Some may call it a VPN (Virtual Private Network) application, but it's much more powerful: it is peer-to-peer, is much simpler, and operates at layer 2 (ethernet). VPNs generally operate at layer-3 (IP), and layer 2 applications like gaming can't be supported with layer 3 tunneling.
