A method for reducing communication network performance degradation using in-band telemetry data includes (a) adding in-band telemetry data to one or more data structures flowing through a network element of a communication network, (b) updating a telemetry table according to first telemetry data that is based on the in-band telemetry data, (c) selecting one of a plurality of paths in the communication network at least partially based on data in the telemetry table, and (d) causing a data structure to be routed through the selected one of the plurality of paths in the communication network.

Systems and methods for reducing communication network performance degradation using in-band telemetry data

A system for managing a core network is provided. The system includes a first computing device including at least one processor in communication with at least one memory device. The first computing device is in communication with a core network. The at least one memory device stores a plurality of instructions, which when executed by the at least one processor cause the at least one processor to store a plurality of historical data associated with the core network, receive current state data from the core network, compare the plurality of historical data with the current state data to determine at least one future state of the core network, and adjust the operation of the core network based on the at least one future state.

Systems and methods for advanced core network controls

A method for scheduling data transmission in a communication network includes (1) using a first scheduler module, scheduling first data packets for transmission via a first communication medium, (2) using a second scheduler module, scheduling second data packets for transmission via the first communication medium, and (3) using a coordinator, allocating transmission resources of the first communication medium among at least the first and second scheduler modules.

Modular schedulers and associated methods

A method for reducing communication network performance degradation using in-band telemetry data includes (1) receiving, at an analytics engine of a communication network, first telemetry data from a first network element of the communication network, the first telemetry data being based on in-band telemetry data at the first network element; (2) determining from the first telemetry data that there is performance degradation in at least a portion of the communication network; and (3) in response to determining that there is performance degradation in at least the portion of the communication network, sending a message from the analytics engine to a second network element of the communication network.

A software defined networking (SDN) controller for a communication network is provided. The SDN controller includes a northbound interface, a southbound interface, and a database as a service (DBaaS) layer. The northbound interface includes an application layer having one or more independent SDN applications. The southbound interface includes an adapter layer having one or more independent device adapters. The DBaaS layer includes a persistent DBaaS unit and a state DBaaS unit.
