As everyone else has said, this is normal for a shared access netowrk. Look for routing protocol updates and other things as well . On ATT's cable-modem network you can see the ospf hello updates, who the DR and BDR is and other things. It can be fun. Try dsniff or some other program and you can see all the traffic on that network :) Be careful though because you will probably get slammed and don't forget to reroute the traffic back out or else someone will know something is wrong.
