  === Purpose of this guide
  
  This guide explains the use of TRex internals and the use of TRex together with Cisco ASR1000 Series routers. The examples illustrate novel traffic generation techniques made possible by TRex. 
  
  == Download and installation
  
  === Hardware recommendations
  
  TRex operates in a Linux application environment, interacting with Linux kernel modules. 
  TRex curretly works on x86 architecture and can operate well on Cisco UCS hardware. The following platforms have been tested and are recommended for operating TRex.
