nexB OpenAssets is a tool for inventorying, managing, and monitoring applications, software, hardware, networks, and generally any IT asset. It is designed so that system administrators, IT, and finance can determine what they have, how it is configured, what it is used for, and how much it is being used, so that informed decisions can be made. It complements existing network management software, integrates with a growing number of protocols and tools, and features no-agent discovery and inventory, configuration management including dependencies and correlation, monitoring, and reporting. It makes extensive and innovative use of XML, Xpath, and Xquery.
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.
LFT (Layer Four Traceroute) is a sort of "traceroute" that often works much faster than the commonly-used Van Jacobson method and goes through many configurations of packet-filter based firewalls. More importantly, LFT implements numerous other features, including TCP, UDP, or ICMP-based traces, AS number lookups through several reliable sources, loose source routing, netblock name lookups, and more. LFT also distinguishes between layer-4 protocols, which make its statistics slightly more realistic, and gives a savvy user the ability to trace protocol routes, not just layer-3 hops.
