Odd network traffic - what is it

I use Zone Alarm Pro as my firewall, and recently I've noticed that
it's icon in the system tray (the traffic bar meter thingy) has been
showing a continuous activity which I don't understand. I've tried
closing all programs (except firewall and virus checker - Avast) to no
avail.

I've now tried using Nirsofts Smartsniff utility, and this shows up
the traffic quite nicely, but I still can't work out what's causing
it.

Here's an extract from the log file (it just shows the header and then
the first packet, following packets are just a repeat of the first).
The IP addresses and Local Host have been grunged before posting this.
Any ideas what's causing this?

I assume the "XXX.YYY" are actually "192.168", right? If so then that
means that you're constantly communicating with your own network router.
Nothing to worry about.
