Abstract: An example network system includes In one example, a network system includes a service orchestrator for managing a mobile network. The service orchestrator is configured to: receive, from a centralized network controller (CNC) for a time sensitive networking (TSN) application, TSN configuration data for a TSN flow between two end station devices for the TSN application; generate, based on the TSN configuration data, an intent to create a network slice in the mobile network to transport packets for the TSN flow; provision the network with the network slice based on the intent, wherein the network slice is associated with slice identification data; and output the slice identification data to cause a user equipment (UE) device attached to the mobile network to map packets for the TSN flow, received from one of the two end station devices, to the network slice.

Abstract: A virtual port group abstraction can facilitate automated configuration of devices in a data center. For example, a data center administrator can define a virtual port group to include a set of logical and physical interfaces for devices allocated to a particular department or other group within a company. An administrator for the department can then utilize a user interface to perform actions with respect to the virtual port group. The actions can include configuration actions, modeling actions and/or deployment actions. An action received by a network management controller such as a Software-Defined Networking (SDN) controller can be converted into the appropriate actions for the relevant logical and physical interfaces that are configured to be part of the virtual port group.

Multiple such messages may be received at an aggregation node that then summarizes the attributes according to respective functions, and sends or publishes a summarized version of the attributes to a still next higher node in the network hierarchy.

Abstract: Techniques are provided herein for a device in a network to receive information configured to indicate a control plane traffic load level for one or more server devices that are configured to manage traffic for messaging and presence clients communicating via a messaging and presence protocol. The control plane traffic is associated with the messaging and presence protocol. A determination is made as to when the control plane traffic load level has become unbalanced among the two or more server devices and in response to determining that the control plane traffic load level has become unbalanced, sending a transfer message to one or more clients comprising information configured to initiate migration of one or more clients from a server device that is relatively overloaded to a server device that is relatively underloaded in order to balance the control plane traffic load level among the two or more server devices.

Abstract: Techniques are described for selecting an optimal data center for instantiating a first cloud service. Embodiments of the invention receive a request specifying a topology of a first cloud service to be hosted by one of a plurality of data centers which provide computing resources to host a plurality of cloud services. A suitability value is then determined for each of the data centers which measures a fitness of the data center for instantiating the first cloud service. In one embodiment, the suitability value is determined by calculating a plurality of metric values for the data center, normalizing the metric values and calculating a weighted average of the normalized values. One of the data centers is then selected for instantiating the first cloud service, based at least in part on the determined suitability values.

Abstract: Techniques are provided to move the services performed on one device to another device in a cloud computing system for a variety of reasons including failure, maintenance or upgrade of the device. A notification is received that services performed by an impacted device in a domain of a plurality of hierarchical domains need to be moved. A determination is made as to whether there are replacement resources available in the domain to perform the services, and if so, the replacement resources are automatically rendered to perform the services. The process continues to higher level domains that have a view into the capabilities of subordinate domains in order to determine where to move the services within the cloud computing system.
