Analysis of Internet Backbone Traffic and Header Anomalies Observed

The dominating Internet protocols, IP and TCP, allow some flexibility in implementation, including a variety of optional features. To support research and further development of these protocols, it is crucial to know about current deployment of protocol specific features and accompanying anomalies. This work is intended to reflect the current characteristics of Internet backbone traffic and point out misbehaviors and potential problems. On 20 consecutive days in April 2006 bidirectional traffic was collected on an OC-192 backbone link.
