Abstract: An enclosure of a mobile terminal and a sputter coating apparatus for making the same are provided. The enclosure includes a substrate and a composite film layer coated onto the substrate. The composite film layer has a thickness changing along a first direction. A difference in thickness between any two regions arranged along the first direction of the composite film layer is less than or equal to 350 nanometers. The enclosure has a spatially varying color corresponding to a wavelength between 400 nanometers and 760 nanometers.

Abstract: The disclosure provides a method for upgrading components of a container-based cluster. The method generally include receiving, at the container-based cluster, an indication of one or more pods and one or more nodes in the cluster to upgrade, adding an annotation to each of the one or more nodes having at least one of the one or more pods running thereon, performing a pod upgrade, and performing a node upgrade, wherein performance of the pod upgrade and the node upgrade overlap at least partially in time, and wherein performing the node upgrade comprises: selecting a first node, determining at a first time that the first node includes an annotation, refraining from upgrading the first node at the first time, determining at a second time after the first time that the first node does not include the annotation, and upgrading the first node at the second time.

Abstract: Example methods and systems for cloud native network function deployment are described. One example may involve a computer system obtaining cluster configuration information associated with multiple single node clusters (SNCs). Based on the cluster configuration information, the computer system may configure (a) a first SNC on a first node and (b) a second SNC on a second node. The computer system may configure (a) a first virtual agent associated with the first SNC, and (b) a second virtual agent associated with the second SNC. In response to receiving a deployment request to deploy a first pod and a second pod, the computer system may process the deployment request by (a) deploying, using the first virtual agent, the first pod on the first SNC, and (b) deploying, using the second virtual agent, the second pod on the second SNC.

Abstract: The disclosure provides a method for preparing a simulation system to simulate upgrade operations for a distributed container orchestration system. The method generally includes monitoring, by a simulation operator of the simulation system, for new resources generated at a management cluster in the distributed container orchestration system, based on the monitoring, discovering, by the simulation operator, a new resource generated at the management cluster specifying a version of container orchestration software supported and made available by the management cluster, and triggering, by the simulation operator, a creation of a new mock virtual machine (VM) template in the simulation system specifying the version of the container orchestration software, wherein the simulation system is configured to use the new mock VM template for simulating mock VMs in the simulation system that are compatible with the version of the container orchestration software supported and made available by the management cluster.

Abstract: The present disclosure provides example computer-implemented method, medium, and system for managing IP addresses for DPDK enabled network interfaces for cloud native pods. One example method includes creating a pod of one or more containers, where the pod connects to multiple networks through multiple network interfaces. A poll mode driver (PMD) is attached to a first network interface of the multiple network interfaces, where the PMD enables one or more data plane development kit (DPDK) applications inside the pod to manage the first network interface. A first container network interface (CNI) is created to handle the DPDK enabled first network interface. A first Internet protocol (IP) address is allocated to the first network interface using the first CNI. The first IP address is passed to the one or more DPDK applications using the first CNI.

Abstract: A computer-implemented method, medium, and system for upgrade of telco node cluster running cloud-native network functions are disclosed. In one computer-implemented method, a worker node group that includes a plurality of worker nodes is determined in a container orchestration platform. A first node to upgrade is determined within the worker node group. All pods in the first node are deactivated by a high availability as a service (HAaaS) module. Standby pods in a second node are activated by the HAaaS module and as active pods. All network traffic associated with all the pods in the first node is migrated to the active pods. The first node is deleted from the worker node group. Hardware resources associated with running the first node are released. A third node is generated as a new worker node in the worker node group and uses the released hardware resources.

Abstract: The current document is directed to methods and subsystems that instantiate and manage mobile-network computational infrastructure. The currently disclosed improved mobile-network-computational-infrastructure orchestration system employs several layers of containerized-application orchestration and management systems. For increased efficiency and security, mobile-network-specific operators are added to the containerized-application orchestration layers in order to extend the functionalities of the containerized-application orchestration layers and move virtualization-layer dependencies from the mobile-network-computational-infrastructure orchestration system down into the containerized-application orchestration layers.
