THE LINK EMULATION IS ACHIEVED BY INTERPOSING THE NETPATH MACHINE EITHER PHYSICALLY OR VIRTUALLY BETWEEN A PAIR OF HOST MACHINES. NETPATH CAN BE CONFIGURED IN THREE DIFFERENT OPERATIONAL MODES: DIRECT INTERPOSITION (MODE 0), VIRTUAL INTERPOSITION, WHICH MAY EITHER BE BETWEEN ROUTERS (MODE 1) OR END HOSTS (MODE 2), AND A LAYER 3 (IP ROUTED) INTERPOSITION MODE.

MGEN

http://cs.itd.nrl.navy.mil/work/mgen/index.php

MGEN PROVIDES THE ABILITY TO PERFORM IP NETWORK PERFORMANCE TESTS AND MEASUREMENTS USING UDP/IP TRAFFIC (TCP IS CURRENTLY BEING DEVELOPED). THE TOOLSET GENERATES REAL-TIME TRAFFIC PATTERNS SO THAT THE NETWORK CAN BE LOADED IN A VARIETY OF WAYS. THE GENERATED TRAFFIC CAN ALSO BE RECEIVED AND LOGGED FOR ANALYSES. SCRIPT FILES ARE USED TO DRIVE THE GENERATED LOADING PATTERNS OVER THE COURSE OF TIME. THESE SCRIPT FILES CAN BE USED TO EMULATE THE TRAFFIC PATTERNS OF UNICAST AND/OR MULTICAST UDP/IP APPLICATIONS. THE RECEIVE PORTION OF THIS TOOL SET CAN BE SCRIPTED TO DYNAMICALLY JOIN AND LEAVE IP MULTICAST GROUPS. MGEN LOG DATA CAN BE USED TO CALCULATE PERFORMANCE STATISTICS ON THROUGHPUT, PACKET LOSS RATES, COMMUNICATION DELAY, AND MORE. MGEN CURRENTLY RUNS ON VARIOUS UNIX-BASED (INCLUDING MACOS X) AND WIN32 PLATFORMS.

MULTICAST BEACON V1.3

http://dast.nlanr.net/projects/Beacon/

THE NLANR/DAST MULTICAST BEACON IS A MULTICAST DIAGNOSTIC TOOL WRITTEN IN PERL WHICH USES THE RTP PROTOCOL (RFC3550) TO PROVIDE USEFUL STATISTICS AND DIAGNOSTIC INFORMATION ABOUT A GIVEN MULTICAST GROUP'S CONNECTIVITY CHARACTERISTICS.
MULTICAST IS A WAY OF DISTRIBUTING IP PACKETS TO A SET OF MACHINES WHICH HAVE EXPRESSED AN INTEREST IN RECEIVING THEM. IT IS A ONE-TO-MANY DISTRIBUTION MODEL SUITABLE FOR VIDEO CONFERENCING AND OTHER FORMS OF DATA SHARING OVER THE NETWORK.
TEAMED UP WITH THE ACCESS GRID, THE MULTICAST BEACON PROVIDES MEASUREMENT DATA FOR THE CURRENT MULTICAST TRAFFIC IN A GROUP. THE ACCESS GRID IS A PROJECT LED BY ANL TO IMPLEMENT LARGE-SCALE DISTRIBUTED COLLABORATION OVER THE NETWORK. IT RELIES ON MULTICAST FOR DISTRIBUTING AUDIO, VIDEO, AND OTHER DATA ACROSS THE NETWORK.
THE MULTICAST BEACON CAN ALSO BE USED AS A GENERAL-PURPOSE MULTICAST MEASUREMENT TOOL AS WELL.

MHEALTH

http://imj.ucsb.edu/mhealth/

MHEALTH, THE MULTICAST HEALTH MONITOR, IS A GRAPHICAL, NEAR REAL-TIME MULTICAST MONITORING TOOL.

THERE IS ALSO A ONE-FLOPPY VERSION OF FREEBSD WHICH INCLUDES DUMMYNET AND A LOT OF OTHER GOODIES, SEE BELOW. IT WORKS BY INTERCEPTING PACKETS IN THEIR WAY THROUGH THE PROTOCOL STACK, AND PASSING THEM THROUGH ONE OR MORE PIPES WHICH SIMULATE THE EFFECTS OF BANDWIDTH LIMITATIONS, PROPAGATION DELAYS, BOUNDED-SIZE QUEUES, PACKET LOSSES, ETC.

MODELNET

http://modelnet.ucsd.edu/

MODELNET IS A LARGE-SCALE NETWORK EMULATOR THAT ALLOWS USERS TO EVALUATE DISTRIBUTED NETWORKED SYSTEMS IN REALISTIC INTERNET-LIKE ENVIRONMENTS. MODELNET ENABLES THE TESTING OF UNMODIFIED PROTOTYPES RUNNING OVER UNMODIFIED OPERATING SYSTEMS ACROSS VARIOUS NETWORKING SCENARIOS. IN SOME SENSE, IT COMBINES THE REPEATABILITY OF SIMULATION WITH THE REALISM OF LIVE DEPLOYMENT. THE MODELNET USER COMMUNITY HAS DEPLOYED IT TO AID IN THE DESIGN AND TESTING OF NOVEL CONTENT DISTRIBUTION NETWORKS, PEER-TO-PEER SYSTEMS, TRANSPORT-LAYER PROTOCOLS, CONTENT-BASED SWITCHES, DISTRIBUTED STREAM PROCESSORS, DISTRIBUTED FILE SYSTEMS, AND NETWORK MEASUREMENT TOOLS.

USERS DEPLOY MODELNET ON THEIR LOCAL-AREA CLUSTER.  EACH INSTANCE OF YOUR APPLICATION RUNS ON A VIRTUAL NODE; MODELNET MULTIPLEXES VIRTUAL NODES ACROSS A SET OF PHYSICAL MACHINES THAT WE CALL EDGE NODES. THE SYSTEM CONFIGURES THE EDGE NODES TO ROUTE THEIR PACKETS THROUGH A MODELNET CORE (CONSISTING OF ONE OR MORE PHYSICAL MACHINES).  THIS CORE SUBJECTS EACH PACKET TO THE DELAY, BANDWIDTH, AND LOSS SPECIFIED IN A TARGET TOPOLOGY.  MODELNET SUPPORTS HOP-BY-HOP EMULATION, CAPTURING THE EFFECTS OF CROSS TRAFFIC AND CONGESTION WITHIN THE NETWORK.
