Abstract: A wireless network may include a base station and user equipment (UE). The UE and base station may perform initial access operations at frequencies greater than or equal to 57 GHz without the use of transmit power control (TPC) signals. The UE devices and the base station may also perform connected mode operations at these frequencies without the use of TPC signals. The UE may perform power saving operations without the use of TPC signals. The base station may handle communications for multiple UE devices in its cell by partitioning the UE into groups based on the estimated path loss for each UE. The base station may perform TDMA, OFDMA, or a combination of TDMA/OFDMA scheduling for the UE devices. Performing these communications without TPC signaling maximizes the amount of network resources available for other purposes, simplifies communication scheduling, and maximizes the efficiency of the network.

Abstract: Some embodiments of the invention provide a method for micro-segmenting traffic flows in a software defined wide area network (SD-WAN). At a first edge forwarding node of a first multi-machine site in the SD-WAN, the method receives, from a particular forwarding element, a first packet of a packet flow originating from a second multi-machine site that is external to the SD-WAN, the packet flow destined for a particular machine at the first multi-machine site. The method uses deep packet inspection (DPI) on the first packet to identify contextual information not provided by the particular forwarding element about the first packet and the packet flow. Based on the identified contextual information, the method applies one or more policies to the first packet before forwarding the first packet to the particular machine.

Abstract: Techniques for using global virtual network instance (VNI) labels in a multi-domain network to route network data with a multi-tenant network overlay are described herein. A routing device provisioned in a network domain of the multi-domain network may register with a service discovery system of the network domain for use of network configuration data to establish routes through the multi-domain network with network nodes. Each network domain of the multi-domain network may include an application programming interface (API) server for processing API requests to make changes to configurations of a network domain.

A service chain may be signaled by global VNI labels to route network traffic through various services prior to reaching a destination endpoint.

Other receiving devices may be configured to receive the unicast transmission as sent to the selected receiving device and to process the transmission as a multicast transmission. Alternatively, a multicast transmission may be sent to all of the receiving devices, and the selected receiving device may be configured to process the multicast transmission as a unicast transmission for the purpose of sending retransmission requests indicating packet loss. Backup packets may be generated and sent to all of the receiving devices to improve content output quality.
