Abstract: Systems and methods for routing traffic through a network along Label-Switched Paths (LSPs) that may extend across multiple autonomous systems include performing Internet Protocol (IP) routing lookups as a packet is transmitted along the LSP. In one implementation, a packet having a predetermined value (which may be inserted by an upstream network device) is received at a network device after travelling along a first segment of an LSP. In response to identifying the predetermined label value of the packet, the network device may perform an IP routing lookup using IP routing information included in the packet to identify a next hop for the packet. The network device may then update a label of the packet such that the packet is routed along a second segment of the LSP and transmit the communication packet to the next hop.

Abstract: Uplink signaling in unlicensed or shared spectrum may be subject to listen before talk procedures resulting in failed signaling transmissions. A user equipment (UE) may perform uplink signaling using a configuration based on whether a base station has entered a channel occupancy time (COT) shared with the UE. A UE may determine that the UE has an uplink transmission for a base station. A UE may determine whether the base station has entered a channel occupancy time that is shared with the UE. A UE may determine configured random access or scheduling request transmission resources based on the channel occupancy time, wherein a density of transmission opportunities is greater outside of the shared channel occupancy time than within the shared channel occupancy time. A UE may transmit a random access message or the scheduling request on selected configured resources.

Abstract: Some embodiments provide a novel method for deploying different virtual networks over several public cloud datacenters for different entities. For each entity, the method (1) identifies a set of public cloud datacenters of one or more public cloud providers to connect a set of machines of the entity, (2) deploys managed forwarding nodes (MFNs) for the entity in the identified set of public cloud datacenters, and then (3) configures the MFNs to implement a virtual network that connects the entity's set of machines across its identified set of public cloud datacenters. In some embodiments, the method identifies the set of public cloud datacenters for an entity by receiving input from the entity's network administrator. In some embodiments, this input specifies the public cloud providers to use and/or the public cloud regions in which the virtual network should be defined. Conjunctively, or alternatively, this input in some embodiments specifies actual public cloud datacenters to use.

Abstract: Embodiments provide popularity-based adaptive bitrate management of linear programming over constrained communications links. Embodiments can operate in context of a communications network communicating with multiple mobile client devices disposed in one or more transport craft. A number of channel offerings, including channels providing linear programming, can be made available via the communications network for consumption by the client devices. Embodiments can compute channel popularity scores for the channel offerings based on a predicted popularity, an estimated popularity, a measured popularity, etc. A bitrate can be determined for each (some or all) of the channel offerings based at least in part on its channel popularity score, so that more popular channel offerings can be communicated at higher bitrates. Determined-bitrate instances of the channel offerings can be obtained and/or generated, and delivered via the communications network, to the client devices for consumption.
