Methods and apparatus for enhancing connectivity for a device backhauled by a wireline communication network. In one embodiment, the device comprises a small-cell or other wireless base station that is backhauled by a DOCSIS system within a managed HFC network, and the method and apparatus enable enhanced connection of user devices serviced by the base station (such as 3GPP UE or CBRS FWA) to a core entity for e.g., authentication and packet session establishment. In one implementation, enhanced Cable Termination System (CMTS) and cable modem (CM) devices coordinate to allocate prioritized service flows to traffic sourced from the base station. These service flows can selectively bypass extant DOCSIS protocols which might otherwise increase connection latency (including connection failure) such as AQM (active queue management) and packet dropping algorithms. In some variants, upstream service flow data rates can also be enhanced through temporary utilization of higher-order modulation and/or coding schemes.

Embodiments of this application disclose a data transmission method, to reduce a delay. If a network device receives burst data, the network device preferentially sends the burst data. The burst data may be data whose data amount is greater than a data amount threshold.

Examples described herein relate to an interface and a network interface device coupled to the interface and comprising circuitry. In some examples, the circuitry is to receive packet data to be egressed, wherein the packet data does not specify a destination for the packet data and process the packet data to be egressed to generate a mapping of ingress packet-to-target based on a determination.

A network device includes processing circuitry and a plurality of ports. The ports connect to a communication network. The processing circuitry is configured to receive, via an input port, data packets and probe packets that are addressed to a common output port, to store the data packets in a first queue and the probe packets in a second queue, both the first queue and the second queue are served by the output port, to produce telemetry data indicative of a state of the network device, based on a processing path that the data packets traverse within the network device, to schedule transmission of the data packets from the first queue at a first priority, and schedule transmission of the probe packets from the second queue at a second priority higher than the first priority, and to modify the scheduled probe packets so as to carry the telemetry data.

A network device includes packet processing circuitry and queue management circuitry. The packet processing circuitry is configured to transmit and receive packets to and from a network. The queue management circuitry is configured to store, in a memory, a queue for queuing data relating to processing of the packets, the queue including a primary buffer and an overflow buffer, to choose between a normal mode and an overflow mode based on a defined condition, to queue the data only in the primary buffer when operating in the normal mode, and, when operating in the overflow mode, to queue the data in a concatenation of the primary buffer and the overflow buffer.

A method for aggregating and regulating messages in a network that has a plurality of pairs of nodes and two transmitting/receiving devices communicating via a bidirectional channel. The method is implemented by each of the transmitting/receiving devices. Each received message may be segmented into packets of a predefined size, and each packet may be allocated to a queue that depends on the origin, the destination, and the priority of the message. One or more frames may then be created, and packets of the queues may be inserted into the frames. Frames may then be sent via the bidirectional channel over a predefined time interval, the number of frames sent over the time interval being dependent on the maximum throughput of the channel and on the useful throughput in each of the transport directions of the channel.

Methods, apparatus and articles of manufacture for advertising network layer reachability information specifying a quality of service for an identified network flow are disclosed. Example methods disclosed herein to specify quality of service for network flows include receiving network layer reachability information including a first quality of service class specified for a first network flow, the network layer reachability information having been advertised by a first network element that is to receive the first network flow. Such example methods can also include updating an incoming packet determined to belong to the first network flow to indicate that the incoming packet belongs to the first quality of service class, the incoming packet being received from a second network element. Such example methods can further include, after updating the incoming packet, routing the incoming packet towards the first network element.

Disclosed are various implementations of cluster capacity management for infrastructure updates. In some examples, cluster hosts for a cluster can be scheduled for an update. A component of a datacenter level resource scheduler can analyze cluster specific resource usage data to identify a cluster scaling decision for the cluster. The datacenter level resource scheduler transmits an indication that the resource scheduler is successfully invoked. Cluster hosts can then be updated.

Embodiments are directed to a computer system for managing data transfer. The computer system includes a memory, a processor communicatively coupled to the memory, a send component and a receive component having a message queue and a controller. A link interface communicatively couples the send component to the receive component. The link interface includes a mainline channel and a sideband channel, and the computer system is configured to perform a method. The method includes transmitting mainline channel messages over the mainline channel from the send component to the receive component. The method further includes transmitting sideband channel messages over the sideband channel from the send component to the message queue of the receive component. The method further includes utilizing the controller to control a flow of the sideband channel messages to the message queue without relying on sending feedback to the send component about the flow.

Systems and methods are disclosed herein for reducing storage space used in tracking behavior of a plurality of network endpoints by modeling the behavior with a behavior model. To this end, control circuitry may determine a respective network endpoint, of a plurality of network endpoints, to which each respective record of a plurality of received records corresponds. The control circuitry then may assign a dedicated queue for each respective network endpoint, and transmit, to each dedicated queue, each record that corresponds to the respective network endpoint to which the respective dedicated queue is assigned. The control circuitry may then determine, for each respective network endpoint, a respective behavior model, and may store each respective behavior model to memory.
