| dc.description.abstract | This thesis investigates the use of packet header information in trace files derived from Internet measurements at MAWI from the years 2020, 2021, and 2022 and scrutinizes these information to report the key changes in the Internet header fields over time. That is, by observing how certain header fields are used, we can determine whether or not the Internet is using newly developed network mechanisms. To do this, we parse the trace files and gather all the unusual data that was discovered in the packets to search for atypical data in the packets. Our research shows that there are no recognizable patterns in the data, confirming no significant changes in the header fields throughout the years. However, we get some exciting findings which leave room for future deep analysis, and the tool we implemented to carry out the analysis have a good chance for further development. | eng |
