    Abstract: Embodiments herein describe a host that polls a network adapter to receive data from a network. That is, the host/CPU/application thread polls the network adapter (e.g., the network card, NIC, or SmartNIC) to determine whether a packet has been received. If so, the host informs the network adapter to store the packet (or a portion of the packet) in a CPU register. If the requested data has not yet been received by the network adapter from the network, the network adapter can delay the responding to the request to provide extra time for the adapter to receive the data from the network.

    Abstract: A network device transmits, to a server, information of an event that has occurred in the network device, compares, with each of a first threshold and a second threshold greater than the first threshold, a metric that corresponds to a state of the network device pertaining to the event, and switches a method of communicating with the server based on the comparison. When the metric exceeds the first threshold while communicating with the server in a polling method with first communication intervals and is smaller than the second threshold, the method of communicating with the server switches to a polling method with second communication intervals that are shorter than the first communication intervals, and when the metric exceeds the second threshold while communicating with the server in the polling method with the second communication intervals, the method of communicating switches with the server to a push method.

    Abstract: Techniques for using traceroute with tunnels and cloud-based systems for determining measures of network performance are presented. Systems and methods provide adaptive probing of a service path in a network, wherein the service path includes a plurality of legs. The systems and methods include, for one or more legs of the plurality of legs, sending a number of probes using one of a plurality of protocols; responsive to receiving a response from the number of probes, determining the one of the plurality of protocols is successful and storing this protocol the one or more legs; and, responsive to failure to receive the response, sending a number of probes using another one of the plurality of protocols and continuing until a successful protocol is determined or all of the plurality of protocols fail.

    Abstract: Disclosed is a method for optimizing a polling of location information of a terminal device, the method, performed by a network node, including: receiving, from the terminal device, data indicative of a movement of the terminal device, the data is received in a payload traffic on a user plane; detecting that the movement of the terminal device is within a reference range, a detection is based on data received from the terminal device; generating a first control signal for re-defining a first polling frequency to occur at a second polling frequency, the second polling frequency being less than the first polling frequency.

    Abstract: Determining a bit rate at which to deliver a packet stream over a network link. An origin device transmits over the network link unsolicited data packets to a destination device while contemporaneously transmitting over the network link a first packet stream encoded at an initial bit rate to the destination device. The origin device may be, but need not be, a content delivery network (CDN) edge node and the destination device may be, but need not be, a cable modem (CM). The origin device determines whether the network link supports delivering a second packet stream in lieu of the first packet stream encoded at a higher bit rate based, at least in part, on an amount of retransmission requests the origin device receives for packets in the first packet stream from the destination device.
