Cross-stratum optimization protocol

摘要

An apparatus comprising an application cross-stratum optimization (CSO) gateway (ACG) coupled to an application layer that handles a plurality of servers, a network CSO gateway (NCG) coupled to a network layer that handles a plurality of network nodes and configured to communicate with the ACG using a CSO protocol (CSOP), and a CSO interface established between the ACG and the NCG that enables the exchange of a plurality of CSOP messages to allow joint application-network resource allocation, provisioning, and optimization. Also disclosed is a network apparatus implemented method comprising sending a user profile from a user plane to an application plane, sending an application profile from the application plane to a network plane via a CSO interface between an ACG and a NCG, and sending network capability information from the network plane to the application plane via the CSO interface.

1. An apparatus comprising an application cross-stratum optimization (CSO) gateway (ACG) comprising:
at least one processor configured to:
process application stratum communications from a plurality of server processes configured to operate in an application stratum and not in a network stratum; andgenerate profiles based on the application stratum communications that can be interpreted by components operating in a network stratum; and at least one transmitter and at least one receiver coupled to the processor and configured to establish a CSO interface with a network CSO gateway (NCG) operating in the network stratum and not the application stratum using a CSO protocol (CSOP), wherein the CSO interface enables an exchange of a plurality of CSOP messages to support joint application-network resource allocation, provisioning, and optimization, and wherein the ACG is further configured to transmit a duration of service profile to the NCG via the CSOP interface to indicate a requested service time of an application, wherein a first of the plurality of CSOP messages comprises a CSOP message header with one or more objects, and wherein the CSOP message header comprises a version field, a message type field, and a message length field, wherein the objects comprise an authentication profile object at the end of the objects in the first CSOP message, wherein the authentication profile object comprises an authentication object class field, a length field, a sub-type field, a Security Parameter Index (SPI) field, and a token, wherein the objects comprise a virtual network topology (VNT) object that comprises a location profile (L) field, a number of sources field, a number of destinations field, a version (V) of Internet Protocol (IP), a plurality of flags, a service request identifier (ID) number, and one of more optional Type/Length/Values (TLVs), and wherein the L field is set to 0 to indicate a point-to-point (P-P) connectivity, 1 to indicate a point-to-multipoint (P-MP) connectivity, 2 to indicate a multipoint-to-point (MP-P) connectivity, 3 to indicate multipoint-to-multipoint (MP-MP) connectivity, or 4 to indicate any-cast connectivity for multi-destination.
