When verifying that FlowView is identifying flows with the correct application, we use tcpreplay to send traffic from packet capture files into an appliance capture interface. The packet captures can be homemade by us or from our customers. These packet captures are typically recorded without filtering, so naturally they will contain extraneous protocols and many mid-conversation sessions that happened to...
