Abstract
Switches within a telecommunications network exchange so-called available bandwidth messages, each of which advertises how much bandwidth remains unassigned on a respective link. The network is of a type in which circuits are provisioned with various predefined numbers of time slots (equivalent to bandwidth). The sending of an available bandwidth message for a given link is triggered by a change in the number of time slots available on that link if that change results in a change in the number of circuit bandwidths that can be accommodated by that link for a newly provisioned circuit.
Claims20
A method, comprising:
- determining, by a switch, an available bandwidth associated with a communications link of a communications network;
- determining, by the switch, that the available bandwidth crosses a threshold, the threshold associated with a circuit;
- and
- sending, by the switch, a message via the communications network, the message advertising the available bandwidth in response to the determining that the available bandwidth crosses the threshold associated with the circuit.
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:
- determining an available bandwidth associated with a communications link of a communications network;
- determining that the available bandwidth crosses a threshold, the threshold associated with adding a circuit;
- and
- sending a message via the communications network, the message advertising the available bandwidth in response to the determining that the available bandwidth crosses the threshold.
A memory device storing instructions that when executed cause a processor to perform operations, the operations comprising:
- determining an available bandwidth associated with a communications link, the communications link associated with a switch of a communications network;
- determining that the available bandwidth crosses a threshold, the threshold associated with subtracting a circuit associated with the switch;
- and
- sending a message via the communications link, the message advertising the available bandwidth in response to the available bandwidth crossing the threshold.
