Abstract

Network resources are provisioned within an application broker according to aggregated requests in an optical network. Resource requests are sorted to form sorted resource requests. The sorted resource requests are sorted according to destinations of the resource requests. The sorted resource requests are aggregated to form aggregated resource requests. Resource allocation is requested for each of the aggregated resource requests from a network border controller based on requirements of the set of set of aggregated resource requests. A set of allocated resources is received from the network border controller. The set of allocated resources is based on requirements of the aggregated resource requests. For each of the aggregated resource requests, network transmissions network receptions are executed utilizing associated allocated resources.
