#### What is the average packet rate (in packets per second to two decimal places) of the trace (as Avg packet rate:)?
Le taux de paquets de la trace est 0.0014 paquet par seconde.
#### What is the packet protocol distribution? (A table showing the 5 top protocols and their respective contributions is fine.)
94.39% des paquets sont des paquets TCP. Les autres paquets n'ont pas d'entête IPv4.

#### Which source sent the most bytes (as Source with most bytes:)?
#### Which source sent the most packets (as Source with most packets:)? Based on your analysis of the trace:
#### List 3 characteristics of the traffic that seem unusual to you.
#### Provide a reasonable explanation for what traffic the trace represents, taking into account the unusual characteristics you have identified.
