NetworkTrafficView is a network monitoring tool that captures the packets pass through your network adapter, and displays general statistics about your network traffic. The packets statistics is grouped by the Ethernet Type, IP Protocol, Source/Destination Addresses, and Source/Destination ports. For every statistics line, the following information is displayed: Ethernet Type (IPv4, IPv6, ARP), IP Protocol (TCP, UDP, ICMP), Source Address, Destination Address, Source Port, Destination Port, Service Name (http, ftp, and so on), Packets Count, Total Packets Size, Total Data Size, Data Speed, Maximum Data Speed, Average Packet Size, First/Last Packet Time, Duration, and process ID/Name (For TCP connections).
Except of a capture driver needed for capturing network packets, NetworkTrafficView doesn’t require any installation process or additional dll files. In order to start using it, simply run the executable file – NetworkTrafficView.exe

After running NetworkTrafficView in the first time, the ‘Capture Options’ window appears on the screen, and you’re requested to choose the capture method and the desired network adapter. In the next time that you use NetworkTrafficView, it’ll automatically start capturing packets with the capture method and the network adapter that you previously selected. You can always change the ‘Capture Options’ again by pressing F9.

After choosing the capture method and network adapter, NetworkTrafficView starts to display your current network traffic, grouped by the Ethernet Type, IP Protocol, Source/Destination Addresses, and Source/Destination ports.

You can press F6 to stop the network traffic capture, F5 to start it again, or Ctrl+X to clear the current network traffic statistics.
Versions History
Version 2.42:
Fixed the default columns size in high DPI mode.
Version 2.41:
Added option to change the sorting column from the menu (View -> Sort By). Like the column header click sorting, if you click again the same sorting menu item, it’ll switch between ascending and descending order. Also, if you hold down the shift key while choosing the sort menu item, you’ll get a secondary sorting.
Version 2.40:
Added ‘SACK Permitted’ column (‘Yes’ or ‘No’ values), which shows whether the source address allows to use TCP SACK (TCP Selective Acknowledgments).
Added ‘TCP SACK’ column, which shows the number of TCP SACK packets sent by the source address.
These options are available only for TCP items and only when the selected options are ‘Display the 2 packet directions in 2 separated lines’ and ‘Group by combination of Ethernet Type, IP Protocol, Addresses, and TCP/UDP Ports’.
Updated to work properly in high DPI mode.
