    Abstract: A network device includes ingress queues for storing data units while the data units are being processed by ingress packet processors, and a plurality of egress buffer memories for storing data units received from the ingress queues while the data units are being processed by the egress packet processors. First circuitry controls respective rates at which data units are transferred from ingress queues to egress buffer memories. Second circuitry monitors the egress buffer memories for congestion and sends, to the first circuitry, flow control messages related to congestion resulting of egress buffer memories. The first circuitry progressively increases over time a rate at which data from each ingress queue are transferred to an egress buffer memory in response to receiving a flow control message that indicates that congestion corresponding to the egress buffer memory has ended.

    Abstract: A method for optimizing Control Unit (CU)-Distributed Unit (DU) flow control to detect congestion over midhaul and take corrective action to reduce packet dropping in the midhaul includes: computing, by DU, desired data rate (DDR) for each data radio bearer (DRB); and sending, by the DU, the DDR every time when desired buffer size (DBS) is sent from DU to CU user plane (CU-UP), along with Downlink Data Delivery Status (DDDS). DU computes DDR for a DRB as follows: DDR=TBS(MCS″, prb″, rank)*(number of slots/subframe in 1 sec)*(beta)*(beta_drb), with TBS being the Transport block size computation, and MCS″=min {(current MCS+MCS_step), MCSmax}.

    Abstract: Embodiments of a secure communication network are disclosed. To implement the embodiments, an ingress core node that includes a processor and a memory storing computer-executable instructions, is presented. The instructions, when executed, cause the processor to receive a data packet. The instructions further cause the processor to compare a slice identifier (ID) associated with the received data packet with one or more slice IDs in an access control list (ACL). The instructions further cause the processor to filter the received data packet based on the comparison indicating an occurrence of a match between the slice ID associated with the data packet and one of the one or more slice IDs in the ACL. The instructions further cause the processor to transmit the filtered data packet to an egress core node of the core network via one or more intermediate core nodes of the core network.

    Abstract: Some embodiments provide a method of reducing network congestion in a virtual network. The method, at a first CFE of the virtual network, receives multiple encapsulated data packets of a data stream. The encapsulated data packets having been encapsulated by a second CFE, operating on a server of the virtual network. The second CFE identifies a load percentage of the server, sets explicit congestion notification (ECN) bits on a percentage of the data packets based on the load percentage of the server, and encapsulates each data packet. The first CFE determines whether to forward a new connection to the second CFE based at least on the percentage of data packets from the first CFE with the ECN bits set.

    Abstract: The present application discloses a method, an apparatus, a device for controlling traffic limitation and a storage medium, and belongs to the field of data processing. The method for controlling traffic limitation includes: acquiring, in response to a present request, a first timestamp of the present request; acquiring a pre-created traffic limitation instance, the traffic limitation instance including N storage blocks, a total number of instance requests, a traffic limitation request threshold number, an identifier of a storage block for a previous request, a second timestamp of the previous request and request waiting time; updating the traffic limitation instance based on a time interval between the first timestamp and the second timestamp, the unit time length, and the traffic limitation request threshold number; and determining whether to perform traffic limitation based on the request waiting time in the updated traffic limitation instance.

    Abstract: A method including activating, by a virtual private network (VPN) server, a first exit internet protocol (IP) address for communicating data associated with a user device having an established VPN connection with the VPN server; deactivating, by a VPN server, the first exit IP address from communicating the data associated with the user device based at least in part on determining that an amount of data communicated utilizing the first exit IP address satisfies a data threshold; and reactivating, by the VPN server at a later time, the first exit IP address for communicating the data associated with the user device based at least in part on determining that the amount of data communicated utilizing the first exit IP address fails to satisfy the data threshold is disclosed. Various other aspects are contemplated.

    Abstract: A network congestion control method includes, during transmission of a first service flow, a first network device that obtains a measurement packet including groups of measurement results corresponding to the first service flow, and each group includes an identifier of a forwarding device on a forwarding path of the first service flow and a measurement value corresponding to the forwarding device. The first network device determines, based on the groups, a congested second network device on the forwarding path. The first network device determines a control policy based on location information of the second network device, where the control policy resolves congestion of the first service flow.
