1. A computer implemented method comprising:

  • sending a resource query from a service stratum gateway with a hardware processor to a transport stratum gateway via a cross-stratum optimization (CSO) interface using a cross-stratum optimization protocol (CSOP) between the service stratum gateway and the transport stratum gateway to enable the different functionalities of the application cross-stratum gateway (ACG) and network CSO gateway (NCG) for related communications, including signaling, messaging, and information exchange,wherein the service stratum gateway collectively handles communications from a plurality of servers managing applications in a service stratum and the transport stratum gateway collectively handles CSOP communications from a plurality of network nodes managing a transport network wherein the CSOP communications include CSO messages that comprise path estimation, path reservation, network topology or virtual machine topology query;

    exchanging status data for monitoring, controlling, and managing the transport network across the cross-stratum optimization (CSO) interface for provisioning application, network congestion, failure information utilizing at least bandwidth profile object used to specify the required bandwidth for a path and comprises a transport layer field, a plurality of flags, an asymmetric bandwidth indicator bit, a reserved field, a downstream of bi-directional bandwidth field, and an upstream bandwidth field; and

    transmitting a reservation request from the service stratum gateway to the transport stratum gateway via the cross-stratum optimization (CSO) interface to reserve a guaranteed bandwidth across the transport network, the service stratum gateway and the transport stratum gateway being at least partially implemented in hardware, the reservation request including a path object having a type length value (TLV) field, the TLV field carrying a path identifier identifying a path to be reserved.
