BalanceNG is a modern, IPv6 capable software IP load balancing solution. It is small, fast, and easy to use and set up. It offers session persistence, different distribution methods (Round Robin, Random, Weighted Random, Least Session, Least Bandwidth, Hash, Agent, and Randomized Agent) and a customizable UDP health check agent in source code. It supports VRRP to set up high availability configurations on multiple nodes. It supports SNMP, integrating the BALANCENG-MIB with Net-SNMPD. It implements a very fast in-memory IP-to-location database, allowing powerful location-based server load-balancing.
Flowgrind is a tool similar to iperf or netperf. It measures throughput and other metrics for TCP and other protocols. It features some unique characteristics: a distributed architecture, sophisticated flow scheduling, Linux kernel TCP statistics, the Anderson-Darling statistical test, rate-limited flows with uniform or Poisson distribution, and separation between control and test traffic.
MammothCopy is a simple, Java-based tool to copy large or many files from one computer on the Internet directly to another. This is also possible with tools like WinSCP and an SSH server, but those are too complex for normal users. MammothCopy is geared towards parents wanting to send photos to their kids, or professionals who want to transfer huge files (only limited to the receiving end’s hard disk space).
RT-Thread RTOS is a real-time operating system for 16-bit to 32-bit microcontrollers, with components which include a hard real-time kernel, a command line shell, a device virtual file system, and a graphic user interface. RT-Thread/GUI is a graphic user interface integrated with RT-Thread. It provides a multi-window, multi-thread graphic user interface. Rich widgets are implemented in RT-Thread/GUI, such as label, button, checkbox, textbox, etc. The typical RAM usage of RT-Thread/GUI is less than 20kB RAM.
Syslog4j provides Java components for client and server implementations of the syslog protocol (RFC 3164). UDP/IP, TCP/IP, TCP/IP over SSL/TLS, Unix Syslog, and Unix Socket Logging are supported. Advanced options are provided, including cryptographic message signatures and hashes. It is heavily tested with JUnit and Emma code coverage.
TML/SIDEX is a BEEP (Block Entensible Exchange Protocol) based SDK for implementing peer to peer and/or client/server communication on various platforms and target languages. It provides type safe data modelling with a simple XML based format that minimizes errors, and its synchronous, asynchronous, and multithreaded interfaces guarantee performance.
libnodelay is an LD_PRELOAD library for disabling Nagle's algorithm. Disabling Nagle's algorithm can result in a performance improvement for latency-sensitive applications that use TCP. Using the library may be easier than digging through a mess of code and confusing or obscure configuration options.
