Difference between PCAP, PCAPNG and CANoe Specific BLF Logging Format

Question:
What is the difference between PCAP, PCAPNG and the CANoe specific BLF logging format?
Answer:

The PCAP format has been defined to capture network traffic. A PCAP file only contains Ethernet frames.

A PCAPNG file that has been recorded with CANoe/CANalyzer additionally contains the channel number that received/sent the Ethernet frame.

BLF files contain additionally:

  • link status 
  • erroneous Ethernet packages
  • frames of other bus systems (CAN, LIN, …)
  • specific information of Vector Network Interfaces (Ethernet checksum, direction, frame duration, HW channel number...), if the Extended Ethernet Logging CANoe option has been previously selected:
