Abstract: In some embodiments, a device in a network receives a packet from a sender that is destined for a receiver. The device forms duplicate packets of the packet. The device assigns a sequence number to the duplicate packets based on an identity of the sender and on a flow identifier associated with the packet. The device sends the duplicate packets with the sequence number via different paths in the network towards the receiver.

Abstract: In one embodiment, a mobile node having a first radio and a second radio applies stateless offline dictionary compression to an uncompressed stream of packets, to form a compressed stream of packets. The first radio of the mobile node communicates with a first access point of a wireless network and the second radio of the mobile node communicates with a second access point of the wireless network. The mobile node selects the first radio to send the uncompressed stream of packets and the second radio to send the compressed stream of packets. The mobile node sends, via the first radio, the uncompressed stream of packets to the first access point over a first wireless path. The mobile node sends, via the second radio, the compressed stream of packets to the second access point over a second wireless path.

Abstract: In one embodiment, a client device enters an area having an overhead mesh of access points, each access point comprising one or more directional transmitters each configured to transmit a beam cone in a substantially downward direction towards a floor of the area. The client device obtains an area-dependent communication schedule for the overhead mesh that is exclusive or partially-exclusive to the client device for the area. The client device sends, during an arbitrary timeslot of the area-dependent communication schedule, a pull request. The client device receives, from a particular access point in the overhead mesh, a packet in response to the pull request.

Abstract: In one embodiment, a controller identifies access points forming an overhead mesh of access points in an area, each access point comprising one or more directional transmitters each configured to transmit a beam cone in a substantially downward direction towards a floor of the area. The controller determines coverage areas on the floor of the area for the one or more directional transmitters of the access points in the overhead mesh. The controller generates, based on the coverage areas, alternating communication schedules for the access points such that a client device at any given location on the floor of the area is within range of a plurality of receiving access points in the overhead mesh and at least one transmitting access point in the overhead mesh at a certain point in time. The controller sends the communication schedules to the access points.
