The drkhtb project was designed with medium to major Internet Service Providers in mind. Featuring extended hashing support, error handling, and simple configuration options, it has proven to be a stable solution for shaping up to 15000 residential clients with both upload and download rules, it is considered stable and is already in use as a production platform in at least one major ISP running 4 shaping bridges, each handling up to 2 Gbit/s, with a total of 48000 active clients and over 60000 filter rules in each direction. At this point there is no reason to believe that further bandwidth cannot be handled by one bridge, but there have not been sufficient resources to extensively test it. It is believed that up to 4 Gbit/s can be shaped on one individual machine serving at least 20000 clients.
MyQoS Free Version is a bandwidth management solution based on FreeBSD 4.X. It provides all the necessary features for a small ISP to do QoS. It is limited to 2Mb/s unless you upgrade to the Standard Version. It is distributed as an appliance image. This image can be burnt to CD for testing before installation.
Panoptes is a scalable, extensible network and host monitoring tool. It includes a dynamic Web management interface based on the Dojo toolkit. It monitors SNMP, TCP port availability, ICMP, HTTP response and content, and SSL certificates internally. It supports monitoring anything else via shell scripts. It also includes a packet capture tool for discovery of hosts, port, and OS.
Meshtool is a mesh network toolkit designed to assist in mesh monitoring, administration, and research. It is Eclipse-based and leverages many Eclipse frameworks such as EMF, GEF, and Teneo. OpenStreetMap is used for 2D map data while 3D geographic data support is in early development stages through the Nasa World Wind. Meshtool is still in an alpha stage, but is being actively developed.
LibreNMS is an autodiscovering PHP/MySQL-based network monitoring system forked from Observium. It aims to be easy to use and painless to deploy, and to support monitoring of a wide range of devices. Observium's license changed to a modified QPL license in May 2012, then was split into free and commercial versions. The aim of LibreNMS is to continue to create a usable NMS, but with a community focus and GPL licensing.
