PcapFileEx.Flows.Summary (pcap_file_ex v0.5.7)

View Source

Aggregated traffic summary for network topology analysis.

Provides a network-administrator view of captured traffic, grouping flows by:

  • UDP: destination service (IP:port) with per-client statistics
  • HTTP/1: server service (IP:port) with per-client request/response metrics
  • HTTP/2: server service (IP:port) with per-client stream statistics

This summary is used by the Diagram API for clean topology rendering.
