The first network device may determine a restricted interface bandwidth of the first network device based on a remaining interface bandwidth of the second network device and a configured bandwidth of a second interface. Subsequently, the first network device may limit a user traffic rate based on the restricted interface bandwidth. The first network device and the second network device are configured to perform load balancing on user traffic, and the restricted interface bandwidth is determined by the first network device based on the remaining interface bandwidth of the second network device, i.e., a bandwidth occupation status of the second network device. The first network device can limit the user traffic rate based on the restricted interface bandwidth.

The present application provides a channel type used to support user QoE expectations, which is, in particular, a QoS and QoE guaranteed channel (QQGC). Also provided is a related method and system for providing a QQGC. Effective bit rate (EBR), average bit rate, and maximum bit rate, are determined and used to support the channel. The EBR can be determined based on QoE reports. An application function, such as a network data analytics function provides the indication of effective bit rate. One or more portions of the application function can be provided in potentially different locations of a communications network and operatively coupled. Alternatively, application function portions can be co-located. The EBR is provided to and used by devices in the network to reserve user plane resources to support data flows at the EBR. The EBR can also be used for admission or rejection of requests for a QQGC channel.

A system, method and computer program of upspeeding a media stream transmitted over a communication link from a sender device to a receiving device.

In one example, a base station entity, for a mobile wireless network, obtains an indication of a first potential Guaranteed Bit Rate (GBR), a first unique identifier associated with the first potential GBR, a first priority level associated with the first potential GBR, a second potential GBR, a second unique identifier associated with the second potential GBR, and a second priority level associated with the second potential GBR. Based on the first priority level being associated with a higher priority than the second priority level, the base station entity determines whether the first potential GBR can be supported. If so, the base station entity provides an indication of the first unique identifier to a core network associated with the mobile wireless network, wherein the indication of the first unique identifier prompts the core network to enforce the first potential GBR.

Data-driven intelligent networking systems and methods are provided. The system can accommodate dynamic traffic while applying injection limits to different traffic classes at an ingress edge port. The system can maintain state information of individual packet flows, which can be set up or released dynamically based on injected data. Each flow can be provided with a flow-specific input queue upon arriving at a switch. Packets of a respective flow can be acknowledged after reaching the egress point of the network, and the acknowledgement packets can be sent back to the ingress point of the flow along the same data path. Furthermore, an edge switch can dynamically allocate the ingress port bandwidth among the traffic classes that are active at a given moment.

Example embodiments provide apparatus, systems and methods to optimise a multicasting operation used to transmit data packets in a communication network.

A system and method is provided for sending congestion notification messages through L3 networks. For example, a data packet is received at a first switch in a first fabric block of an L3 network, and the first switch performs source MAC tagging of the data packet. The data packet is then forwarded to a second switch in a second fabric block of the L3 network, and the source MAC tag is maintained by the second switch and any intermediate switches. The second switch determines, in response to receiving the data packet, whether it is congested, and generates a notification message if it is congested. The notification message is L2 forwarded to the first fabric block, and further forwarded from the first switch to a source of the data packet using ACL matching.

A method for communication includes transmitting data packets from a communication device to a network. Upon receiving in the communication device a congestion notification from the network, a rate of transmission of the data packets from the communication device to the network is reduced. While transmitting the data packets, after reducing the rate of transmission, the rate of transmission is increased incrementally when a predefined volume of data has been transmitted since having made a previous change in the rate of transmission.
