Actually I was somewhat inaccurate here as our filters only work on sync connections, but the concept is applicable. its not much different, except it can be done on a per line or DLCI basis, which means that the overhead is restricted to incoming or outgoing traffic on a particular connection. You can also set specific data types to "low priority", which can be made to be discarded first when the system hits a backup threshold or to be transmitted with the DE bit enabled on a frame relay link.
