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.

Network slices for time sensitive networking

A method includes deploying a network device within a fabric having a management network by attaching the network device through the management network to a port of a role allocator, wherein the role allocator includes one or more ports designated as first level port connections and one or more other ports designated as second level port connections. If the deployed network device is attached to one of the ports designated as first level port connections, the deployed network device is configured as a first level device. If the deployed network device is attached to one of the ports designated as second level port connections, the deployed network device is configured as a second level device.

Configuration for multi-stage network fabrics

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.

Virtual port group

Techniques are described for detecting failure of one or more virtual computing environments and causing a migration of workloads. In some examples, a computing system includes a storage medium and processing circuitry having access to the storage medium. The processing circuitry is configured to communicate with a plurality of virtual computing environments (VCEs), including a first VCE and a second VCE, wherein each of the plurality of VCEs is operated by a different public cloud provider. The processing circuitry is further configured to deploy a group of workloads to the first VCE, detect a failure of at least a portion of the first VCE, and output, to the first VCE and responsive to detecting the failure, an instruction to transfer a set of workloads of the group of workloads to the second VCE to thereby cause a migration of the set of workloads to the second VCE.

Migrating workloads in multicloud computing environments

A system for configuring a data center includes a fabric management server coupled to a management switch. A provisional Software Defined Networking (SDN) controller executing on the fabric management server can discover physical servers coupled to the management switch, receive network interface configuration information from the physical servers, and use the discovered network interface configuration information to determine a configuration for switches and servers coupled to an IP fabric. The configuration can be migrated to a full functionality SDN controller.

Initializing server configurations in a data center

An example method includes determining, by a network controller, based on a high-level data model, vendor-agnostic device information for a first network device, translating the vendor-agnostic device information into vendor-specific device information, sending, to the first network device, first configuration information included in the vendor-specific device information to cause the first network device to switch into a maintenance mode and enable diversion of network traffic from the first network device to a second network device, responsive to verifying that the first network device has diverted the traffic, initiating maintenance procedures on the first network device while the first network device is in the maintenance mode, and sending, to the first network device, second configuration information included in the vendor-specific device information to cause the first network device to switch out of the maintenance mode and enable reversion of network traffic from the second device to the first network device.

Automation of maintenance mode operations for network devices

An example method includes identifying, based on a received indication, at least a first network device that is to be placed in the maintenance mode, determining device information for the first network device, sending, to the first network device, first configuration information included in the device information to cause the first network device to switch into a maintenance mode and enable diversion of network traffic from the first network device to a second network device, responsive to verifying that the first network device has diverted the traffic, initiating maintenance procedures on the first network device while the first network device is in the maintenance mode, and sending, to the first network device, second configuration information included in the device information to cause the first network device to switch out of the maintenance mode and enable reversion of network traffic from the second device to the first network device.

Reduced configuration for multi-stage network fabrics

In one embodiment a method includes at first a network device, identifying an attribute of the first network device, selecting a function that defines how the attribute is to be summarized together with a same attribute of a second network device, generating a message that comprises a set of information comprising an identification of the attribute and the function, and sending the message to, e.g., a next higher node in a network hierarchy of which the network device is a part. 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.

Extensible attribute summarization

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.

Active load distribution for control plane traffic using a messaging and presence protocol

In one embodiment, a method comprises receiving a request for a distributed service, the distributed service offered by a service provider via a data communications network having service delivery locations reachable via a prescribed physical topology; identifying the service delivery locations within a prescribed logical topology overlying the prescribed physical topology, the prescribed logical topology segregating the distributed service from other network traffic on the prescribed physical topology; and identifying one or more of the service delivery locations optimized for providing the distributed service to at least one service consumption location in the prescribed logical topology according to a prescribed service level agreement with the service provider.

Placement of service delivery locations of a distributed computing service based on logical topology

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.
