Abstract
A router device has a line relay processing unit including a PUSH processing unit for adding a label to a frame and forwarding the frame and a POP processing unit for removing the label from the frame and forwarding the frame, and a relay processing unit including a SWAP processing unit for swapping the label of the frame and forwarding the frame.
Claims15
A router device for relaying a frame in an MPLS (Multi Protocol Label Switching) network, comprising:
- a line relay processing unit including a PUSH processing unit which adds a label to the frame and forwards the frame, and a POP processing unit which removes the label from the frame and forwards the frame;
- and
- a relay processing unit including a SWAP processing unit which swaps the label of the frame and forwards the frame.
A scalability improvement method for use in a router device for relaying a frame in an MPLS (Multi Protocol Label Switching) network, comprising the steps of:
- providing a line relay processing unit including a PUSH processing unit which adds a label to the frame and forwards the frame, and a POP processing unit which removes the label from the frame and forwards the frame;
- and
- providing a relay processing unit including a SWAP processing unit which swaps the label of the frame and forwards the frame.
A router device for relaying a frame in an MPLS (Multi Protocol Label Switching) network, comprising:
- a line relay processing means including a PUSH processing unit for adding a label to the frame and forwarding the frame, and a POP processing means for removing the label from the frame and forwarding the frame;
- and
- a relay processing means including a SWAP processing unit for swapping the label of the frame and forwarding the frame.
