Abstract: Systems, methods, and computer-readable storage media for multi-destination TCP communications using bit indexed explicit replication (BIER). In some examples, a system can generate a TCP packet associated with a TCP session involving a set of destination devices, and encode an array of bits into the TCP packet to yield a TCP multicast packet. The array of bits can define the destination devices as destinations for the multicast packet. The system can transmit the TCP multicast packet towards the destination devices through a BIER domain. The system can receive acknowledgements from a first subset of the destination devices. Based on the acknowledgements, the system can determine that the first subset of the destination devices received the multicast packet and a second subset of the destination devices did not receive the multicast packet. The system can then retransmit the multicast packet to the second subset of the destination devices.

Abstract: A method comprises: obtaining, at an apparatus, first voice data from a first user device associated with a first speaker participant in a communication session; detecting voice data loss or degradation in the first voice data; determining whether prediction probability of correctly compensating for the voice data loss or degradation is greater than a predetermined probability threshold; if the prediction probability is greater than the predetermined probability threshold, first compensating for the voice data loss or degradation using historical voice data received by the apparatus prior to receiving of the first voice data, the first compensating producing first compensated voice data; if the prediction probability is not greater than the predetermined probability threshold, second compensating for the voice data loss or degradation by inserting noise to the first voice data to produce second compensated voice data; and outputting the first compensated voice data or the second compensated voice data.

Abstract: In one embodiment, a supervisory device in a network forms a virtual access point (VAP) for a node in the network whereby a plurality of access points (APs) in the network are mapped to the VAP as part of a VAP mapping. The node treats the APs in the VAP mapping as a single AP for purposes of communicating with the network. The supervisory device determines a data traffic management strategy for the node based on traffic associated with the node. The supervisory device instructs the APs in the VAP mapping to implement the data traffic management strategy for the node.

Abstract: In one embodiment, a supervisory device in a network forms a virtual access point (VAP) for a node in the network. A plurality of access points (APs) in the network are mapped to the VAP as part of a VAP mapping and the node treats the APs in the VAP mapping as a single AP for purposes of communicating with the network. The supervisory device determines a traffic type of traffic associated with the node. The supervisory device assigns the node to a selected wireless channel based in part on the traffic type of the traffic associated with the node. The supervisory device controls the VAP to use the channel assigned to the node.

Abstract: In one embodiment, a splitting device in a computer network transmits to a combining device first and second portions of a data stream via first and second tunnels, respectively, where packets of the data stream indicate a time of transmission of the packets from the splitting device, a first and second transmission rate of the packets on a respective one of the first and second tunnels, and sequencing information of the packets within the data stream. The splitting device receives from the combining device a first and second receive rate of the packets for each of the first and second tunnels, respectively. In response to the first receive rate being less than the first transmission rate, the splitting device reduces the first transmission rate and increases the second transmission rate.

Abstract: In one embodiment, a server instructs one or more networking devices in a local area network (LAN) to form virtual network overlay in the LAN that redirects traffic associated with a particular node in the LAN to the server. The server receives the redirected traffic associated with the particular node. The server determines a node profile for the particular node based in part on an analysis of the redirected traffic. The server configures the particular node based on the determined node profile for the particular node.

Abstract: In one embodiment, a device in a network receives data associated with a particular location. The device determines when the device is at the particular location by monitoring a local position of the device relative to the particular location. The device identifies a node in the network as being co-located with the device at the particular location. The device shares the data with the identified node based on the device and the node being co-located at the particular location.

Abstract: In one embodiment, a device in a network identifies a node in the network that is not synchronized to a network time synchronization mechanism. The device determines a scheduled reception time for a particular deterministic traffic flow at which the device is to receive the traffic flow from the node. The device sends, prior to the scheduled reception time, a request to the node for the particular deterministic traffic flow. The request identifies the particular deterministic traffic flow and causes the node to send the traffic flow to the device. The device receives the particular deterministic traffic flow from the node at the scheduled reception time.
