METHOD AND SYSTEM FOR CROSS-STRATUM OPTIMIZATION IN APPLICATION-TRANSPORT NETWORKS

摘要

An apparatus comprising an application cross-stratum optimization (CSO) gateway (ACG) configured to communicate with a plurality of servers at an application layer, and a network CSO gateway (NCG) coupled to the ACG via an application-network interface (ANI) and configured to communicate with a plurality of network nodes at a plurality of network layers below the application layer, wherein the ANI allows joint application-network resource allocation, provisioning, and optimization. Also disclosed is a network apparatus implemented method comprising receiving at a service controller in a service plane a resource reservation request from an application controller coupled to an application plane to enable an application for a user, computing a path for the application, allocating the resource for the path at a network plane using network maintained databases, and forwarding a response with the allocated resource to the application plane via the service controller and the application controller.
