  50. in the pcap format back onto the wire for testing NIDS and other passive
  51. devices. Over time, it was enhanced to be able to test in-line network
  52. devices. However, a re-occurring feature request for tcpreplay is
  53. to connect to a server in order to test applications and host TCP/IP
  54. stacks. It was determined early on, that adding this feature to tcpreplay
  55. was far too complex, so I decided to create a new tool specifically
  56. designed for this.</SPAN>

  58. <SPAN ID="hue52">Flowreplay is designed to replay traffic at Layer
  59. 4 or 7 depending on the protocol rather then at Layer 2 like tcpreplay
  60. does. This allows flowreplay to connect to one or more servers using
  61. a pcap savefile as the basis of the connections. Hence, flowreplay
  62. allows the testing of applications running on real servers rather
  63. then passive devices. </SPAN>
