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 paths for carrying a service flow to a destination, the one or more candidate paths including at least a first path extending from a core network to a user equipment (UE) accessing a radio access network (RAN), the first path including a first set of links connected in series, wherein at least one link in the first set of links is a wireless link in the RAN; obtaining load parameters associated with one or more links that either are included in the first set of links or interfere with one or more with wireless links in the first set of links; determining a network cost for carrying the service flow over the first path in accordance with the load parameters and at least one cost function associated at least one link in with the first set of links; and prompting establishment of the first path when the network cost for carrying the service flow over the first path is less than a threshold.
