Abstract: A method of multicasting packets by a forwarding element that includes several packet replicators and several egress pipelines. Each packet replicator receives a data structure associated with a multicast packet that identifies a multicast group. Each packet replicator identifies a first physical egress port of a first egress pipeline for sending the multicast packet to a member of the multicast group. The first physical egress port is a member of LAG. Each packet replicator determines that the first physical egress port is not operational and identifies a second physical port in the LAG for sending the multicast packet to the member of the multicast group. When a packet replicator is connected to the same egress pipeline as the second physical egress, the packet replicator provides the identification of the second physical egress port to the egress pipeline to send the packet to the multicast member. Otherwise the packet replicator drops the packet.

Abstract: This application provides a channel access indication method and device. The method includes: receiving, by a first communications device, a channel synchronization request sent by a second communications device, where the channel synchronization request is used to request the first communications device to send a synchronization frame to the second communications device, and a wake-up receiver is configured for the second communications device; and according to the channel synchronization request and a time at which the second communications device is woken up and that is learned by the first communications device based on preset signaling, sending, by the first communications device when a channel is idle, the synchronization frame to the woken-up second communications device, where the synchronization frame is used to instruct the woken-up second communications device to access the channel after receiving the synchronization frame.

Abstract: In one embodiment, a method comprises: generating, by a constrained low power and lossy network (LLN) device that is localized within a subregion of an LLN, a thin destination oriented directed acyclic graph (DODAG) having up to a prescribed limit of attached LLN devices at each hop of the thin DODAG based on generating a DODAG information object (DIO) message specifying an instruction for limiting attachment at each hop of the thin DODAG to the prescribed limit; and causing, by the constrained LLN device, multicast-only transmissions via the thin DODAG based on inserting into the DIO message a multicast-only transmission mode via the thin DODAG and outputting the DIO message, the DIO message causing each neighboring LLN device to selectively attach to the constrained LLN device as an attached child LLN device based on the instruction and execute the multicast-only transmissions via the thin DODAG.

Abstract: Computing systems and methods for facilitating mobile transactions are disclosed. An example method includes: detecting, via a hardware communication interface, a user check-in request based at least on a communication exchange between a user device and a signaling device at a location. The communication exchange corresponds to a proximity of the user device to the signaling device. The method further includes: determining a user identifier associated with the user device based at least on the user check-in request; and transmitting one or more promotional items to the user device based at least on the user identifier.

Abstract: A network includes a mobile network node (MNN) that includes a mobile node communications manager (MNCM) to facilitate wireless communications to a plurality of stationary network nodes (SNNs) in a wireless network via a wireless network protocol. The MNCM utilizes a multicast address received over the wireless network. The multicast address is assigned to a predetermined network time slot to communicate uplink data from the MNN to the SNNs. The MNN receives downlink data via a separate predetermined network address and time slot assigned to a given SNN.

Abstract: The present disclosure provides systems, methods and computer-readable media for maintaining network connectivity, in a LISP based network, when one or more network edge nodes lose connectivity to a LISP control plane of the network, using multicast messaging. In one example, a method includes receiving a connection request from a first endpoint to a second endpoint communicatively coupled to a second edge node; determining, by the first edge node, that a connection session to a control plane for locating the second endpoint has failed; querying one or more available edge nodes for locating the second endpoint using a multicast message; locating the second endpoint based on at least one query response received from the one or more available edge nodes, at least one query response including an identifier of the second endpoint; and establishing the connection request between the first endpoint and the second endpoint upon locating the second endpoint.
