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.

1. An apparatus comprising:
an application cross-stratum optimization (CSO) gateway (ACG) configured to:
communicate with a plurality of servers at an application layer to obtain application resource information; andrequest virtual network topology information from a network layer via a network CSO gateway (NCG); and the 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 to obtain the virtual network topology information, wherein the ANI supports transmission of virtual network topology information to the ACG for optimized server selection based on the application resource information and the virtual network topology information.
