Network Slice Sharing of Resource Objects

A method implemented by a target forwarding device and comprising:

• obtaining first information about a first network slice, wherein the first information indicates a first resource object associated with the first network slice and comprising a resource, wherein the resource is a network topology resource or a forwarding resource;
• obtaining second information about a second network slice, wherein the second information indicates a second resource object associated with the second network slice and comprising the resource;
• forwarding a first data packet to the first network slice using the first resource object;
• and
• forwarding a second data packet to the second network slice using the second resource object.

A controller comprising:

• a processor configured to:
• generate first information about a first network slice, wherein the first information indicates a first resource object associated with the first network slice and comprising a resource, wherein the resource is a network topology resource or a forwarding resource;
• and
• generate second information about a second network slice, wherein the second information indicates a second resource object associated with the second network slice and comprising the resource;
• and
• a transceiver coupled to the processor and configured to send the first information and the second information to one or more target forwarding devices.

A target forwarding device comprising:

• a transceiver configured to:
• obtain first information about a first network slice, wherein the first information indicates a first resource object associated with the first network slice and comprising a resource, wherein the resource is a network topology resource or a forwarding resource;
• obtain second information about a second network slice, wherein the second information indicates a second resource object associated with the second network slice and comprising the resource;
• forward a first data packet to the first network slice using the first resource object;
• and
• forward a second data packet to the second network slice using the second resource object.
