Diagnosis of Communication Problems in Captured Network Traffic

Abstract

This thesis deals with a system for measuring the quality of captured data on the network. The focus is mainly on packet loss caused by insufficient capture rate. The quality of captured network traffic is evaluated on TCP protocol, which implements sequence and acknowledgment numbers. Based on these numbers, we can detect data, that has been correctly transmitted, but we do not see them in the capture. Existing tools, such as capTCP or Wireshark, are not suitable for this analysis because they cannot comprehensively analyze the quality of captured communication, filter communication flows according the metrics and do not fit into system DISTANCE. This thesis is also focused on configuration problems of DHCP protocol.

Keywords

quality of captured communication, not captured segments, sequence and acknowledgment numbers, DHCP configuration problems diagnosis, TCP, UDP, PCAP, Wireshark, RocksDB, system DISTANCE
