Network control method, apparatus, and system

An apparatus, comprising:

• at least one processor;
• one or more memories coupled to the at least one processor and storing instructions for execution by the at least one processor, the instructions executed by the at least one processor to cause the apparatus to:
• obtain first link state information and second link state information, wherein the first link state information indicates a link state of an Internet Protocol (IP) network, and the second link state information indicates a link state of an optical network;
• and
• determine third link state information based on the first link state information and the second link state information, wherein the third link state information comprises the link state of the IP network and the link state of the optical network;
• and
• compute a path based on the third link state information.

A system, comprising:

• an Internet Protocol (IP) network, comprising IP network elements;
• an optical network, comprising optical network elements;
• a cross-layer link, configured to connect the IP network element and the optical network element;
• and
• a master controller, configured to obtain first link state information and second link state information, wherein the first link state information indicates a link state of the IP network, and the second link state information indicates a link state of the optical network;
• determine third link state information based on the first link state information and the second link state information, wherein the third link state information comprises the link state of the IP network and the link state of the optical network;
• and compute a path based on the third link state information.

A non-transitory storage medium storing a program that is executable by one or more processors, the program including instructions for:

• obtaining first link state information and second link state information, wherein the first link state information indicates a link state of an Internet Protocol (IP) network, and the second link state information indicates a link state of an optical network;
• determining third link state information based on the first link state information and the second link state information, wherein the third link state information comprises the link state of the IP network and the link state of the optical network;
• and
• computing a path based on the third link state information.
