A method for method for managing a computer network is proposed, which comprises: performing data collection configuration for at least one network node of the computer network belonging to a set of one or more network nodes corresponding to a first depth level of a routing tree, the data collection configuration comprising: receiving respective first configuration data from at least one child node in the routing tree of the at least one network node of the computer network, wherein the at least child node corresponds to a second depth level of the routing tree which immediately follows the first depth level in a sequence of depth levels of the routing tree, and generating second configuration data based on the received first configuration data.

Aspects described herein relate to resource allocation in an integrated access and backhaul (IAB) system. In an example, the aspects include determining, by a central unit (CU), a configuration of not-available (NA) resources for a parent node, wherein the NA resources of the parent node correspond to a set of one or more resources configured at the parent distributed unit (DU) as being unavailable for uplink and downlink communications between the parent DU and a child node; and modifying, by the CU, the first child DU resource configuration to create a modified child DU resource configuration.

A method of managing a computer network is described. The method comprising: identifying a characteristic of data traffic being sent over the computer network; and applying a policy to at least part of the network, the policy defining the operation of at least part of the network in event of a failure within the network and being defined on the basis of the characteristic of the data traffic.

A method for processing data packets in a communication network includes establishing a path for a flow of the data packets through the communication network. At a node along the path having a plurality of aggregated ports, a port is selected from among the plurality to serve as part of the path. A label is chosen responsively to the selected port. The label is attached to the data packets in the flow at a point on the path upstream from the node. Upon receiving the data packets at the node, the data packets are switched through the selected port responsively to the label.

Systems and methods to reserve resources is provided. In exemplary embodiments, a selection of a profile from a user is received. A dynamic graphical user interface is generated, using one or more processors. The dynamic graphical user interface allows the user to configure a topology based on the selected profile. The dynamic graphical user interface provides input fields in which the user may select a resource. An indication of the selected applicable topology property for configuring the topology is received. A topology is automatically generating based in part on the selected applicable topology property.

In one embodiment, a method includes determining, by one or more processors, a weight of a link between a first node and a second node of a network, wherein the weight is proportional to a probability value of forwarding a probe packet from the first node to the second node of the network. The method also includes adjusting, by the processors, the weight of the link between the first node and the second node using binary exponential backoff. The method further includes determining, by the processors, to forward the probe packet to the second node of the network based on the adjusted weight of the link and one or more field values of the probe packet.

Various embodiments are provided for using pessimistic scheduling for topology optimized workload placement by a processor in a computing environment. An excessive amount of computing resources may be requested (e.g., a pessimistic request) to execute a workload as compared to a required amount of the computing resources to execute the workload. The workload may be assigned to a selected configuration of the excessive amount of computing resources and releasing a remaining amount of the excessive amount of computing resources.

This application discloses a packet processing method and a related apparatus, applied to a network slice. The method includes: A first network device obtains a first packet, where the first packet includes a first slice identifier, the first slice identifier includes a plurality of consecutive sub-identifiers, the plurality of sub-identifiers indicate different attributes of a first network slice, and the first slice identifier identifies the first network slice to which the first packet belongs. The first network device forwards the first packet based on the first slice identifier. In this solution, a slice identifier including a plurality of sub-identifiers is carried in a packet. Different sub-identifiers indicate different attributes of a network slice.

Systems and methods for automated failure recovery of subsystems of a management system are described. The subsystems are built and modeled as services, and their management, specifically their failure recovery, is done in a manner similar to that of services and resources managed by the management system. The management system consists of a microkernel, service managers, and management services. Each service, whether a managed service or a management service, is managed by a service manager. The service manager itself is a service and so is in turn managed by the microkernel. Both managed services and management services are monitored via in-band and out-of-band mechanisms, and the performance metrics and alerts are transported through an event system to the appropriate service manager. If a service fails, the service manager takes policy-based remedial steps including, for example, restarting the failed service.

A method for processing low-rate service data, an apparatus, and a system, where the method includes: mapping low-rate service data into a newly defined low-rate data frame, where a rate of the low-rate data frame matches a rate of the low-rate service data, the data frame includes an overhead area and a payload area, the payload area is used to carry the low-rate service data, a rate of the payload area in the low-rate data frame is not less than the rate of the low-rate service data, and the rate of the low-rate service data is less than 1 Gbps; mapping the low-rate data frame into one or more slots in another data frame, where a rate of the slot is not greater than 100 Mbps; mapping the other data frame into an optical transport unit (OTU) frame; and sending the OTU frame.
