I could use some hints.
      
      
        I have a single link between host router/switches and host with 
        several miles between the routers (fiber optic). This is TCP/IP data. 
        I'd like to measure or analyze the quality of the link. I could mirror 
        a port with Wireshark on each router for both ends.
      
      
        After reviewing Wireshark some notions I had are:
      
      
        A) Checksum: Run applications from host, capture all data and analyse 
        captured data at far end for "Checksum" errors to create a close 
        estimate of Bit Error Rate by counting total packets to packets 
        w/Checksum errors. This with checksum offloading off.
      
      
        B) Round Trip Time (RTT): Send continuous ping from host, capture lots 
        of data and analyze RTT times. I could do this by exporting data and 
        using a spreadsheet to analyze. Does Wireshark do this already? It 
        doesnt look like the Service Response Time feature would do this.
      
      
        Any thought would be greatly appreciated
