Method and system to represent the impact of load variation on service outage over multiple links

摘要

Increased resource utilization efficiency can be improved by modeling path costs during admission and path-selection. Specifically, path costs for candidate paths are modeled based on load characteristics (e.g., current load, load variation, etc.) of links in the candidate paths. Path costs can represent any quantifiable cost or liability associated with transporting a service flow over the corresponding path. For example, path costs can correspond to a probability that at least one link in the path will experience an outage when transporting the service flow, a price charged by a network operator (NTO) for transporting the traffic flow over the candidate path, or a total network cost for transporting the flow over a candidate path. The candidate path having the lowest path cost is selected to transport a service flow.

1. A method for resource provisioning, the method comprising:
identifying, by a controller, one or more candidate wireless paths for carrying a service flow to a destination, the one or more candidate wireless paths including at least a first wireless path comprising a first set of links connected in series; obtaining load characteristics associated with the first set of links; determining a first cost for carrying the service flow over the first wireless path in accordance with the load characteristics associated with the first set of links; and prompting establishment of the first wireless path when the first cost for carrying the service flow over the first wireless path is less than a threshold, wherein the first cost includes a component corresponding to a probability that one or more links in the first set of links will experience an outage if the service flow is carried over the first wireless path.
