AQuoSA is an open architecture for the provisioning of adaptive Quality of Service functionality into the Linux kernel. The project features a flexible, portable, and lightweight software architecture for supporting QoS-related services on top of a general-purpose operating system as Linux. The architecture is well founded on formal scheduling analysis and control theoretical results. At the core of the software is an adaptive Resource Reservation layer that is capable of dynamically adapting the CPU allocation for QoS-aware applications based on their run-time requirements.
Qosmos NI_DUMP (“Network Intelligence Dump”) is Linux-based tool inspired by the popular tcpdump, enabling you to read, print, or save packet data related to traffic traveling over your network. Qosmos NI_DUMP is a light and versatile packet capture tool that recognizes 120 of the most commonly used protocols and applications, including SMTP, HTTP, MySQL, and NFs. This represents a small but useful sample of the full Qosmos Protocol Portfolio, comprising over 300 protocols and 4000 metadata. Unlike conventional packet dump tools, Qosmos NI_Dump can identify protocols using non-standard TCP or UDP ports, and incorporates an easy-to-use advanced filter expression language that enables users to zoom in on data of most interest to them, such as FTP transfers matching a particular filename or HTTP requests containing a particular keyword.
Coretrace is a lightweight tool for debugging embedded Linux applications. It works by analyzing core files from crashed applications and outputs a short plain-text backtrace, suitable for putting into logfiles. The basic idea is to let the failing unit do self analysis of core files and report those back home during device maintenance lifetime. Non-interactive small-sized embedded systems are the primary targets, so small footprint is of major concern, since it will be stored on flash. Currently the compiled size is approximately 20 kb.
KEDR is a framework to facilitate dynamic analysis of kernel modules in Linux ("KEDR" is an acronym for "KErnel-mode Drivers in Runtime"). KEDR allows you to intercept the calls that a kernel module makes to the functions exported by other modules and by the kernel proper. The tools provided by the framework can record the arguments and return values of these functions to a trace, perform fault simulation according to user-defined scenarios, and check the kernel modules for memory leaks and some other kinds of problems. Custom data collection and analysis tools for the Linux kernel can also be built on top of KEDR framework.
