Abstract
A first and a second switching node establish a tunnel to transport a packet through a multiprotocol label-switching (MPLS) network. The tunnel is associated with a unique tunnel key. One or more virtual ciruit (VC) labels are automatically generated using the tunnel key.
Claims20
In a Multiprotocol Label Switching (MPLS) network environment having a first switching node and a second switching node, a method comprising:
- establishing a tunnel key to identify a tunnel path the tunnel path used to transport a packet from the first switching node and the second switching node;
- and
- automatically generating one or more virtual circuit (VC) labels based on the tunnel key.
A switching node for a Multiprotocol Label Switching (MPLS) network, comprising:
- a routing control module to establish a tunnel key, the tunnel key to identify a tunnel path from the switching node to a second switching node;
- and,
- a VC generator module to automatically generate one or more VC labels based on the tunnel key.
A computer-readable medium, having stored thereon sequences of instructions which are executable by a processor, and which, when executed by the processor, cause the processor to:
- establish a tunnel key identifying a tunnel path, the tunnel path used to transport a packet between a first switching node and a second switching node;
- and
- automatically generate one or more VC labels based on the tunnel key.
A switching node, comprising:
- a routing control means for establishing a tunnel key, the tunnel key to identify a tunnel path from the switching node to a second switching node;
- and,
- a virtual circuit (VC) label generator means for generating one or more VC labels based on the tunnel key.
