Abstract: A router encapsulates a payload of a packet in a generic routing encapsulation (GRE) header that defines a connectionless GRE tunnel. The router also encapsulates the payload and the GRE header in one or more reliable transport headers associated with a connection formed using a reliable transport layer. The router conveys the packet via the connectionless GRE tunnel over the reliable transport layer. In some cases, the GRE header is a network virtualization using GRE (NVGRE) header that allows multiple NVGRE overlays to be multiplexed onto a single IP underlay tunnel. The reliable transport layer can be implemented as Transmission Control Protocol (TCP) layer, a QUIC protocol, a Stream Control Transmission Protocol (SCTP) or a QUIC protocol to establish a set of multiplexed sub-connections or streams over a single connection between two endpoints of the tunnel, or a transport layer security (TLS) cryptographic protocol.

The second packet header includes the plurality of second-type identifiers. The segment routing device sends the second packet to the second network.

Abstract: Systems, apparatuses, and methods are described for automatically establishing a virtual private network (VPN) based on detecting a connection to a public network. A computing device may detect a connection to a public network. The computing device may determine whether the connection to the public network is secured and/or may determine a quality of that connection. If the connection is unsecure and/or if the quality satisfies a quality threshold, the computing device may establish a VPN session.

Abstract: A base station (BS) and a method for wireless communication are provided. The method includes transmitting a first radio resource control (RRC) configuration that configures a radio link monitoring configuration that includes a beam failure detection (BFD) timer and a beam failure indication (BFI) count threshold. The first RRC configuration enables a user equipment (UE) to: start or restart the BFD timer by a medium access control (MAC) entity of the UE each time a BFI is received from a lower layer; and initiate a beam failure recovery (BFR) procedure upon determining that the number of the received BFIs is greater than or equal to the BFI count threshold. The method further includes transmitting a second RRC configuration that reconfigures the radio link monitoring configuration. The second RRC configuration enables the UE to set the BFI counter to zero in response to receiving the second RRC configuration.

Abstract: Techniques for integrating disparate headend traffic ingress services with disparate backend services are disclosed herein. The techniques may include receiving, at a classification and forwarding node of a networked computing environment, a data packet encapsulated according to a first encapsulation protocol that is supported by the classification and forwarding node. The techniques may also include determining, by the classification and forwarding node, that the data packet is to be sent to a service from among a group of services associated with the networked computing environment. The classification and forwarding node may also determine whether the first encapsulation protocol is supported by the service. Based at least in part on determining that the service supports a second encapsulation protocol different than the first encapsulation protocol, the classification and forwarding node may encapsulate the data packet according to the second encapsulation protocol and send the data packet to the service.

Abstract: Systems, apparatuses, and methods are described for wireless communications. A wireless device may inform a base station of a failure of a beam failure recovery procedure for a secondary cell. The wireless device may include an indicator of the failure in a report providing, or configured to provide, values for signal strength or other characteristic of a downlink signal. The indicator may be in addition to, and/or may replace, one or more indicators of signal strength or other characteristic.

Abstract: Methods, systems, and devices for wireless communication are described. Wireless communications systems may support beamformed transmissions between devices (e.g., to improve coverage range). The beamformed transmissions may depend on discovery and maintenance of receive and transmit beams over which a given device may communicate with another device. Various receive and transmit beams for a given device may be compared using reference signals. As the number of devices attempting to access a cell increases, the number of reference signals to be transmitted may scale proportionally. Large numbers of reference signals may flood time-frequency resources of the system and/or require excessive processing at a mobile device. Scrambling sequences for reference signals may be employed to improve efficiency of resource usage. In aspects, the scrambling sequences may be implicitly determined (e.g., based on resources over which the access request was transmitted).

Abstract: A terminal is disclosed, which is capable of appropriately determining a resource to which a DCI is mapped. A DCI receiver (203) receives first and second downlink (DL) control signals, and a signal demultiplexer (202) demultiplexes a DL data signal from a received signal, using the first and the second DL control signals. The DCI receiver (203) identifies a resource for the second DL control signal based on information on the first DL control signal, or information on the DL data signal, indicated by the first DL control signal.

Abstract: A system for multicast traffic management in an overlay tunnel fabric is provided. The system can operate a first switch and a second switch of the fabric as part of a virtual switch. The virtual switch can operate as a gateway for the fabric. The system can efficiently deploy a rendezvous point (RP) for a multicast group at the first switch. During operation, the system can determine whether to synchronize a registration packet associated with the multicast group with the second switch based on a type of a first ingress connection associated with the registration packet. The system can then determine whether to receive subsequent registration packets for the multicast group based on the type of the first ingress connection and reception of a join request for the multicast group. The type of a respective connection indicates whether the connection includes an overlay tunnel.

Abstract: A radio network device is operative to transmit uplink data on a physical uplink shared channel aggregating two or more contiguous slots. The device is further operative to transmit, in addition to the uplink data, Uplink Control Information (UCI) in at least one of the aggregated slots. The UCI may comprise a HARQ ACK/NACK. The UCI is configured in response to Downlink Control Information (DCI) received from a serving network node. The DCI also includes a UL scheduling grant for the physical uplink channel. The UCI may be configured in the physical uplink channel transmission in a variety of ways. Various amounts of frequency resource (e.g., subcarriers) may be allocated to UCI. The subcarriers may be non-contiguous. In slot aggregation, the UCI subcarriers may frequency hop from slot to slot. The UCI may be encoded differently in different slots, to facilitate early decoding by a receiver (which may, for example immediately prepare a re-transmission in the case of a NACK).

Abstract: A network device can automatically select an execution plan from a set of possible execution plans that cause a first set of traffic assignments in a network to be changed to a second set of traffic assignments. A traffic assignment indicates assignments of the traffic to one or more tunnels, internal routes and/or peer links to be utilized for routing traffic received at provider edge routers through a network to prefixes. A traffic assignment can have various parameters such as bandwidth, transmission costs etc. Each execution plan has one or more steps, and each step has one or more traffic assignment changes progressing from the first set of traffic assignments to the second set of traffic assignments. The network device can automatically select an execution plan based on an evaluation metric determined for each execution plan. The evaluation metric can be a cost based metric or a quality based metric.
