 /*
  * Perform analysis on a series of event pairs.
  *
- * If one event pair is a packet, an exchange is composed of at least two
- * packets, one in each direction. There should be a non-negative minimum
- * "round trip time" (RTT) between the first and last event of the exchange.
- * This RTT should be as small as possible so these packets should be closely
- * related in time like a data packet and an acknowledgement packet. If the
- * events analyzed are such that the minimum RTT can be zero, there's nothing
- * gained in analyzing exchanges beyond what can already be figured out by
- * analyzing packets.
- *
- * An exchange can also consist of more than two packets, in case one packet
- * single handedly acknowledges many data packets.
- *
  * Args:
  *   syncState     container for synchronization data
- *   packet        structure containing the many events
+ *   exchange      structure containing the many events
