Patent ID: 7565436

Claim:
A method of implementing Quality of Service (QoS) across Frame Relay and Ethernet networks to enable similar QoS to be provided to packets in both the Frame Relay and Ethernet networks as the packets pass from one network to the other, the method comprising the steps of: receiving a packet from the Ethernet network; identifying the packet according to an Ethernet protocol for servicing; determining an Ethernet QoS metric for the identified packet, the QoS metric being associated with the packet on the Ethernet network, said determining an Ethernet QoS metric includes considering Ethernet information, wherein said Ethernet information includes p-bits information; and based upon the determined Ethernet QoS metric, determining a corresponding Frame Relay QoS metric; and servicing the identified packet for transmission on the Frame Relay network in accordance with the determined corresponding Frame Relay QoS metric protocol to thereby enable similar QoS to be provided to the packet in the Frame Relay network as was provided to the packet in the Ethernet network, wherein said servicing the identified racket further includes assigning a drop precedence to the packet based on the p-bits information.
