DESCRIPTION:Some packet loss is expected\, but how do you define "some"? Th
 is talk examines the characteristics of expected loss due to signal interf
 erence or router queue drops\, versus excessive retransmissions indicating
  deeper issues.\n\n- Practice with a "normal" TCP stream which has slight 
 packet loss. How long should it take\, and what are those darn Dup ACK's?\
 n- Identifying the source of excessive retransmissions - your network or t
 heirs?\n- Retransmissions of specific packet types within TCP streams. Is 
 it always or only sometimes?\n- High retransmission counts in a pcap captu
 red within a building\, yet the switches and routers report no errors. Wha
 t could cause that?\n\nBy analyzing real-world examples\, you'll gain a de
 tailed understanding of TCP retransmission patterns\, learn to distinguish
  "normal" from "excessive"\, and troubleshoot accordingly.
