text: Before proceeding, look at the second largest component of your RTT, which is*serialization*
  *delay*. Serialization delay is the amount of time that is required to move a packet of data of a 
  specific size across a network link of a certain bandwidth. The required time to move a 
  specific amount of data decreases as the data transmission rate increases. 
  
  Figure 11-155 shows the orders of magnitude of difference between the link bandwidths. It is 
  easy to see how 1920 errors can arise when your bandwidth is insufficient. Never use a 
  TCP/IP ping to measure RTT for FCIP traffic.
