Abstract: A method of deploying a network service across a plurality of data centers, includes the steps of: in response to a request for or relating to a network service, identifying virtual network functions associated with the network service and determining network connectivity requirements of the virtual network functions, issuing commands to provision a virtual link between at least two of the data centers in which the virtual network functions are to be deployed.

Abstract: A computer-implemented method, medium, and system for implementing a pluggable diagnostic tool for Telco radio access network (RAN) troubleshooting are disclosed. In one computer-implemented method, one or more containerized network function (CNF) instances are generated in a container orchestration platform by a test system and by using a telecommunication cloud automation (TCA) platform executed in the container orchestration platform, where the test system is onboarded to the TCA platform, and the one or more CNF instances are associated with 5G RAN. A customer resources (CR) file is received by the test system, where the CR file defines multiple test cases associated with validation of the TCA platform. The CR file is transmitted to a cluster of nodes in the container orchestration platform. The validation of the TCA platform is executed at the cluster of nodes based on the one or more CNF instances and the CR file.

Abstract: System and method for performing diagnostics in a multi-cloud system triggers a diagnostic workflow in a first cloud computing environment of the multi-cloud system in response to an event in the multi-cloud system and execute the diagnostic workflow in the first cloud computing environment by identifying components in the multi-cloud system that are affected by the event and obtaining probes for the identified components. For each component of the identified components, a sub-flow of the diagnostic workflow is started to run at least one probe of the obtained probes to generate a diagnostic result of the component. A diagnostic report is generated based on the diagnostic result of each component of the identified components.

Abstract: Some embodiments provide a method that generating a host profile for deploying a first network function. the method uses a virtual machine configuration operator in a remote data center to configure one or more virtual machines implementing a workload cluster to perform the first network function based on the host profile. The method uses the virtual machine configuration operator to configure one or more virtual machines implementing a management cluster based on the host profile. The workload cluster is managed by the management cluster.

Abstract: Described herein are systems, methods, and software to manage the encapsulation of layer two communications across computing sites. In one example, a gateway at a first computing site may receive an encapsulated packet from a second gateway at a second computing site. After receiving the encapsulated packet, the gateway decapsulates the encapsulated packet and determines that the decapsulated packet satisfies MSS criteria. The gateway further, in response to determining that the decapsulated packet satisfies the MSS criteria, modifies an MSS option associated with the decapsulated packet to a maximum value and forwards the decapsulated packet to a destination virtual node in the first computing site.
