Abstract

See full text

A method and apparatus allows a switch or other network equipment device to provide Quality of Service information to a router or other user equipment devices using a management interface such as frame relay LMI. The switch and router negotiate the version of the management interface that has the capabilities of the present invention. The router can then request Quality of Service parameters from the switch. The switch provides the parameters and the router can use them to route information via the switch. If the parameters are changed in the switch or other changes occur, the switch notifies the router and the router can then request updated parameters from the switch.
