The method includes acquiring a test configuration for executing a multi-node performance validation test, wherein the test configuration identifies: a multi-node network performance test, carried out by an application layer, that specifies a technology-independent test script that is generic to particular technologies for providing performance validation-related services, and a node group upon which the multi-node network performance test is to be performed. The method further includes executing the multi-node network performance validation test by the application layer issuing requests to a core layer comprising a set of technology-specific services that issue, in accordance with the application layer requests, technology-specific commands to external services during performance validation of nodes within the node group. ## Claims ### Claim 1 A method, carried out by a network automation system platform, for automated multi-node performance validation testing on a communications network, the method comprising: acquiring a test configuration for executing a multi-node performance validation test, wherein the test configuration identifies: a multi-node network performance test, carried out by an application layer, that specifies a technology-independent test script that is generic to particular technologies for providing performance validation-related services, and a node group upon which the multi-node network performance test is to be performed; and executing the multi-node network performance validation test by the application layer issuing requests to a core layer comprising a set of technology-specific services that issue, in accordance with the application layer requests, technology-specific commands to external services during performance validation of nodes within the node group; and receiving, by the core layer, a set of responses from the external services corresponding to execution of the set of technology-specific commands by the external services during performance validation testing of the node group. ### Claim 2 (depends on 1) The method of claim 1 further comprising: issuing, by the core layer in accordance with commands received from the application layer after the receiving, a set of technology-specific network production state restoration commands. ### Claim 3 (depends on 1) The method of claim 1 further comprising: issuing, by an application layer application, requests to a common services layer service callable by a multitude of application layer applications. ### Claim 4 (depends on 1) The method of claim 1 wherein the technology-specific commands comprise calls invoking performance validation testing performed by an external testing service. ### Claim 5 (depends on 1) The method of claim 1 wherein the network automation system platform implements a representational state transfer (REST) interface architecture for interfacing the application layer to the external services via the core layer. ### Claim 6 (depends on 1) The method of claim 1 wherein the application layer comprises a Y.1564 application for carrying out performance validation on a backhaul network node. ### Claim 7 A network automation system platform on a computer system including a processor and a non-transitory computer-readable medium including computer-executable instructions that, when executed by the processor, facilitate the computer system carrying out a method for automated multi-node performance validation testing on a communications network, the method comprising: acquiring a test configuration for executing a multi-node performance validation test, wherein the test configuration identifies: a multi-node network performance test, carried out by an application layer, that specifies a technology-independent test script that is generic to particular technologies for providing performance validation-related services, and a node group upon which the multi-node network performance test is to be performed; and executing the multi-node network performance validation test by the application layer issuing requests to a core layer comprising a set of technology-specific services that issue, in accordance with the application layer requests, technology-specific commands to external services during performance validation of nodes within the node group; and receiving, by the core layer, a set of responses from the external services corresponding to execution of the set of technology-specific commands by the external services during performance validation testing of the node group. ### Claim 8 (depends on 7) The network automation system platform of claim 7, wherein the method further comprises: issuing, by the core layer in accordance with commands received from the application layer after the receiving, a set of technology-specific network production state restoration commands. ### Claim 9 (depends on 7) The network automation system platform of claim 7, wherein the method further comprises: issuing, by an application layer application, requests to a common services layer service callable by a multitude of application layer applications. ### Claim 10 (depends on 7) The network automation system platform of claim 7 wherein the technology-specific commands comprise calls invoking performance validation testing performed by an external testing service. ### Claim 11 (depends on 7) The network automation system platform of claim 7 wherein the network automation system platform implements a representational state transfer (REST) interface architecture for interfacing the application layer to the external services via the core layer. ### Claim 12 (depends on 7) The network automation system platform of claim 7 wherein the application layer comprises a Y.1564 application for carrying out performance validation on a backhaul network node.
