PacketScope is a network connection monitor for Mac OS X. It allows you to see incoming and outgoing connections to and from your computer. Is your network or internet connection just slow or down? You can use PacketScope to view activity on any network interface in your system. You can also find out which application is using the connection and how much data is transferred per interface. PacketScope provides graphs that allows you to see how much data is transferred and how many packets per second from selected network interfaces.
