GroundWork Monitor Community Edition 5.3.0 (GA) (Default branch)
ImageGroundWork Monitor Community Edition can give you insight into your computing infrastructure, allowing you to see the current and historical states of all your computers: servers, desktops, and laptops, all of your network devices, all of your services (like TCP/IP and Web services), and all of your applications (like mail servers and database apps). You can choose to be alerted when something goes awry via pager, SMS, email, or phone, and even set up automatic restarts or fall-overs. License: GNU General Public License v2Changes:
Increased scalability: in lab testing, an approximately 50% increase in the out-of-the-box throughput has been measured. Improved installation: all software prerequisites are now included in a single, graphical, distribution-agnostic download. Updates to Nagios (3), RRDtool, MySQL, BIRT, and PHP. Updated Plugins and Profiles.Image

NAME

     mod_cc -- Modular congestion control

DESCRIPTION

     The modular congestion control framework allows the TCP implementation to dynamically change the congestion control algorithm used by new and
     existing connections.  Algorithms are identified by a unique ascii(7) name.  Algorithm modules can be compiled into the kernel or loaded as
     kernel modules using the kld(4) facility.

     The default algorithm is NewReno, and all connections use the default unless explicitly overridden using the TCP_CONGESTION socket option
     (see tcp(4) for details).	The default can be changed using a sysctl(3) MIB variable detailed in the MIB Variables section below.

MIB Variables
     The framework exposes the following variables in the net.inet.tcp.cc branch of the sysctl(3) MIB:

     available	Read-only list of currently available congestion control algorithms by name.

     algorithm	Returns the current default congestion control algorithm when read, and changes the default when set.  When attempting to change
		the default algorithm, this variable should be set to one of the names listed by the net.inet.tcp.cc.available MIB variable.

ACKNOWLEDGEMENTS

     Development and testing of this software were made possible in part by grants from the FreeBSD Foundation and Cisco University Research Pro-
     gram Fund at Community Foundation Silicon Valley.

HISTORY

     The mod_cc modular congestion control framework first appeared in FreeBSD 9.0.

     The framework was first released in 2007 by James Healy and Lawrence Stewart whilst working on the NewTCP research project at Swinburne Uni-
     versity of Technology's Centre for Advanced Internet Architectures, Melbourne, Australia, which was made possible in part by a grant from the
     Cisco University Research Program Fund at Community Foundation Silicon Valley.  More details are available at:
