Abstract: Systems and methods for protecting external memory resources to prevent bandwidth collapse in a network processor. One embodiment is a network processor including an input port configured to receive packets from a source device, on-chip memory configured to store packets in queues, an external memory interface configured to couple the on-chip memory with an external memory providing a backing store to the on-chip memory, and bandwidth monitor configured to measure a bandwidth utilization of the external memory. The network processor also includes a processor configured to apply the bandwidth utilization of the external memory to a congestion notification profile, to generate one or more congestion notifications based on the bandwidth utilization applied to the congestion notification profile, and to send the one or more congestion notifications to the source device to request decreasing packet rate for decreasing the bandwidth utilization of the external memory.

Abstract: According to an aspect, there is provided a local diagnosis system comprising means for performing the following. The local diagnosis system detects one or more anomaly events associated with a communications network. Each anomaly event defines an anomaly pattern describing a data point in a performance indicator space. Then, the local diagnosis system updates one or more local cluster models to incorporate the one or more anomaly patterns within complexity constraints. Each of the one or more local cluster models corresponds to a different diagnosis label defining a diagnosis. In response to failing according to one or more per-defined criteria to incorporate, in the updating, the one or more anomaly patterns to the one or more local cluster models, the local diagnosis system forwards at least the one or more local cluster models and one or more associated diagnosis labels to a central diagnosis system for further diagnosis.

Abstract: The present disclosure relates generally to the field of wireless communications, and in particular to techniques for efficiently transferring, among network nodes, an access context required to initiate data transfer when a user equipment (UE) is in an active or suspended Radio Access Network (RAN) connection state. The techniques disclosed herein involve identifying, based on UE-specific data (such, for example, as mobility information, a traffic profile), one or more relevant network nodes where the UE in the suspended RAN connection state could be located at the time when next data transfer needs to be initiated. After that, the access context is sent from an anchor network node to said one or more relevant network nodes. By sending the access context in this manner, network signalling overhead and storage capacity overhead may be significantly reduced.

Abstract: According to an example embodiment, a device is configured to a deep reinforcement learning, DRL, agent to simulate the behaviour of a network component. The DRL agent takes the network state and user traffic as inputs. It generates the next network state and user performances. A training algorithm of the simulator is configured for the DRL agents and it is derived to deal with the property of time-correlation in network components. The simulator uses a training algorithm so that it enables robust inference under a limited number of transitions collected with the real network components and users. It is derived with state augmentation by using an autoencoder architecture. It is also configured by a reward estimation algorithm by using local regression, for example with a Gaussian Process.
