Messenger port 1900 to my router

I am not very familiar with the Messenger protocol but I am seeing a constant traffic from my windows machines to port 1900 of my routers internal interfaces. It is always the default gateway address of the windows machines. From what I could tell Messenger should be sending to a multicast address not the unicast address of the gateway. Is something going on here?
