Observing all outgoing/incoming network connections, sorted by process .exe

Question

What Windows 7 tool (possibly portable freeware, with a GUI) allows to show a list of network outgoing/incoming connections, sorted by process? Something similar to the usual Task manager (taskmgr.exe) but for networking:

Example:

chrome.exe                                 [X] Click to block
      + 198.237.216.12:80    
      + 198.237.216.11:1827                 (collapsable list that we can open/close)
      ...
avastservice.exe                           [X] Click to block
      + 118.237.216.47:9173
blahblah.exe                               [X] Click to block
      + 122.222.116.11:13
      => this one looks suspicious, we never asked this software to 
         have connections, let's block it!

Answer 1

I finally found the solution: CurrPorts is perfect for this!
