Method and Apparatus for Initiating Routing Messages in a Communication Network

A system, comprising:

• a processor;
• and
• a memory device, the memory device storing code, the code when executed causing the processor to perform operations, the operations comprising:
• comparing an amount of available bandwidth to a threshold value, the amount of available bandwidth associated with a communications link in a communications network;
• determining the amount of available bandwidth exceeds the threshold value;
• sending a message via the communications link, the message specifying the amount of available bandwidth;
• periodically generating a periodic update to the amount of available bandwidth associated with the communications link;
• and
• periodically sending advertising messages via the communications link, each one of the advertising messages specifying the periodic update to the amount of available bandwidth.

A memory device storing instructions that when executed cause a processor to perform operations, the operations comprising:

• comparing an amount of available bandwidth to a threshold value, the amount of available bandwidth associated with a communications link in a communications network;
• determining the amount of available bandwidth exceeds the threshold value;
• sending a message via the communications link, the message specifying the amount of available bandwidth;
• periodically generating a periodic update to the amount of available bandwidth associated with the communications link;
• and
• periodically sending advertising messages via the communications link, each one of the advertising messages specifying the periodic update to the amount of available bandwidth.
