A network device includes a plurality of ports; a switch configured to switch data frames between the plurality of ports; and a processor configured to obtain one or more measurement values based on network traffic associated with the data frames, responsive to detection of a threshold-crossing event of a measurement value, wherein the threshold-crossing event is one of an indication and a precursor of one or more of an abnormal and unexpected event associated with the network traffic, cause collection of a plurality of time series of measurement values of the network traffic by one or more components in the network device, and send a combination of the plurality of time series as a telemetric data stream for analysis by a network management system related to the abnormal/unexpected event.

A network device predicts end-to-end channel capacity entropy to permit use of optimal throughput settings in a network. The network device stores class definitions for a network condition; identifies multiple input features to correlate with the class definitions; generates a multiclass classification model that produces an importance score for each of the multiple input features, wherein the importance score reflects the contribution of an input feature to the network condition; selects two or more of the multiple input features with highest importance scores as influential features; predicts the behavior of the influential features to identify a current class, from the class definitions, for the network condition over an end-to-end communication channel; and sends an estimated network condition, based on the current class, to a device for traffic optimization.

This disclosure provides methods, apparatuses, and computer-readable mediums for managing network devices in a telecommunication network using dynamically modifiable graph data schema. The method may be executed by one or more processors and may include creating an entity model specification file; validating a syntax of the entity model specification file based on parsing the entity model specification file; based on the syntax being valid, validating the entity model specification file, wherein validating the entity model specification file comprises converting the entity model specification file into a graph data schema; and initiating the graph data schema associated with the entity model specification file, wherein the initiating comprises changing the graph data schema to a ready state.

Methods, systems, and computer-readable storage media for network subscription management. An example method includes receiving a request, from a collaboration network, for sub-network subscription offerings that are available for a user of the collaboration network. The user is identified in the collaboration network using a collaboration network identifier and is currently subscribed to a first subscription plan offering of a first sub-network. Compatible sub-network subscription offerings that are available for the user of the collaboration network that are compatible with the first subscription plan offering are determined and provided to the collaboration network. An indication of a selected second subscription plan offering for a second sub-network is received. Subscription service interface information for connecting to the second sub-network is determined and a connection is established to the second sub-network using the subscription service interface information.

A method for monitoring a network. The method includes generating a measurement value of network traffic processed by a component of a number of components of a network device. Based on the measurement value meeting a pre-determined criterion, a threshold-crossing event of the component is detected. In response to the threshold-crossing event, a number of time series of measurement values of the network traffic are generated. In particular, each time series is generated by one of the number of components. Accordingly, a combination of the number of time series is sent as a telemetric data stream by the network device to a network management system of the network.

A method implemented by a service rendezvous point (SRP) comprises receiving, by a receiver of the SRP, a plurality of register messages from a plurality of service switch points (SSPs), each of the register messages comprising at least one of resource information or service information, each of the SSPs being associated with a different network domain, sending, by a transmitter of the SRP, a plurality of report messages to the plurality of SSPs, each of the report messages comprising resource allocation information for each of the network domains for a service, the resource allocation information including an amount of resources to be allocated at the each of the network domains for the service, and maintaining, at a memory of the SRP, a SSP database storing at least one of the resource allocation information of each of the network domains, the resource information of each of the network domains, and the service information of each of the network domains.
