Mosquitto is an open source (BSD licensed) message broker that implements the MQ Telemetry Transport protocol versions 3.1 and 3.1.1. MQTT provides a lightweight method of carrying out messaging using a publish/subscribe model. This makes it suitable for "machine to machine" messaging such as with low power sensors or mobile devices such as phones, embedded computers or microcontrollers like the Arduino.

A sample implementaiton set of "L2TP-IPv6PD" client using mpd. "OCN IPv6", provided by NTT Communications Corp, was the first commercial tunnel service using "L2TP-IPv6PD".

MPICH is an implementation of the Message-Passing Interface (MPI) standard. The goal of MPICH is to provide an MPI implementation that supports different computation and communication platforms including commodity clusters, high-speed networks and proprietary high-end computing systems. It also enables cutting-edge research in MPI through an easy-to-extend modular framework for other derived implementations.

Netembryo is a network abstraction library plus some misc utility functions used as foundation for feng, libnemesi, felix.

MPICH2 is an implementation of the Message-Passing Interface (MPI). The goals of MPICH2 are to provide an MPI implementation for important platforms, including clusters, SMPs, and massively parallel processors. It also provides a vehicle for MPI implementation research and for developing new and better parallel programming environments

Mping is a system for collecting packet delay and loss statistics in a TCP/IP network using ICMP echo. Mping is based on original ping(8) with following new features: - Ability to ping multiple hosts simultaneously - Prints 10/50/90-percentile as well as min/avg/max.

mrouted is an implementation of the DVMRP multicast routing protocol. It turns a UNIX workstation into a DVMRP multicast router with tunnel support, in order to cross non-multicast-aware routers.

netselect is an ultrafast intelligent parallelizing binary-search implementation of "ping." netselect determines several facts about all of the hosts given on the command line, much faster than you would if you tried to use ping and traceroute. For example, if I type: netselect -v ftp.fceia.unr.edu.ar \ ftp.kulnet.kuleuven.ac.be \ ftp.cdrom.com ftp.debian.org \ ftp.de.debian.org It tells me statistics about each of the hostnames I provided, in much less time than doing a whole bunch of traceroutes.

Msend is an implementation of the RFC1312 message protocol. It can be used as a network aware replacement for write and wall. This package contains the client "msend" and the server "mesgd".

The nettest and nettestd commands invoke client and server programs that are used for timing data throughput of vari- ous methods of interprocess communication. For TCP and OSI connections, the nettest program establishes a connec- tion with the nettestd program, and then it does count writes of size bytes, followed by count reads of size bytes. For UDP, the nettest program performs only writes; reads are not performed. The nettestd program, if used with UDP connections, reads the data packets and prints a message for each data packet it receives. The number and size of the reads and writes may not correlate with the number and size of the actual data packets that are trans- ferred; it depends on the protocol that is chosen. If you append an optional k (or K) to the size, count, or bufsize value, the number specified is multiplied by 1024.
