= OTG -- ORBIT Traffic Generator =

'''OTG (ORBIT Traffic Generator)''' software is designed for in NSF '''[http://www.orbit-lab.org ORBIT ]''' Testbed Project. It is a typical application to inject packets into the network and test the link performances, similar to [http://www.netperf.org/netperf/NetperfPage.html Netperf]. ORBIT Traffic Generator is a special tool for ORBIT experimenters
to generate traffic for testing network performance.  Its primary focus is to
generate bulk data of various characteristics and use either TCP or UDP protocol
to transport data. 

'''ORBIT Traffic Generator''' Software consists of two components. 
One is the '''OTG (ORBIT Traffic Generator)'''; the other is '''OTR (Orbit Traffic Receiver)'''.
They are used in pair to transmit and receive data respectively. The '''OTG''' software
has a flexible design to support various configuration of generators such as 
''CBR'' and ''exponential on/off'' traffic. 

'''OTG''' is also integrated with [wiki:Documentation/OML OML] component for
providing real-time measurements for network applications.
