LiveTcpUdpWatch is another portable Nirsoft utility that permits you to retrieve real-time TCP and UDP activity on your system.

This portable utility will feel similar to other Nirsoft apps like CurrPorts and NetTrafficView and does operate much in the same way but uses different techniques for gathering the details it presents. For instance, LiveTcpUdpWatch uses event tracing API to pull live information from the Windows Kernel for every TCP/UDP packet sent/received on your system. As opposed to CurrPorts, LiveTcpUdpWatch captures all the UDP activity with process information without using a network sniffer.

You will be provided with the TCP/UDP/IPv4/IPv6 protocol, local/remote IP address/port, the total number of sent/received bytes and packets, the connect/disconnect times (For TCP only), as well as the process (ID and path) responsible for this activity. All the details are displayed from the clean and easy-to-navigate Nirsoft interface making it usable for all user types.
