Abstract: The disclosure provides an approach for deploying an software defined networking (SDN) solution for overlay routing of traffic on a host with colocated a workload virtual machine (VM), addressable on an overlay network and VM addressable on an underlay network.

The base station may receive the group-based beam report from the UE based on the indication, and the base station may configure communication with the UE on a joint channel based on the group-based beam report.

Abstract: Peer devices may wirelessly communicate with each other over a bidirectional sidelink logical channel (LCH) through an established bidirectional sidelink radio bearer. An initiating device of the peer devices may dynamically select a logical channel ID for establishing a fully bidirectional or semi-bidirectional SLRB. At least two alternative sidelink radio resource control (PC5-RRC) procedures may ensure the SLRB parameters are configured correctly in the established logical channel. The procedures also allow the network to configure a limited SLRB which is used to couple the SLRB configuration in the direction in which limited traffic (e.g. feedback information such as robust header compression feedback and/or status reports) is transmitted.

Abstract: Methods, systems, and computer readable media described herein can be operable to facilitate an IGMP fastleave using a listener reference count. A gateway proxy saves each listener for every specific multicast group, thus the gateway knows if a listener is the last one in the group when it receives a leave report from a listener. The gateway leaves the group immediately without sending specific query if the leave report comes from the last listener of the current group, thereby significantly reducing the leave latency. Otherwise, the standard procedure wins, and the gateway sends out a specific query when the leave report is not from the last listener.

Abstract: In a connected vehicle environment, network connection parameters such as a network congestion window and bit rate are automatically adjusted dependent on a location of a vehicle in order to optimize network performance. A geospatial database stores learned relationships between network performance of a connected vehicle at different physical locations when configured in accordance with different network parameters. The vehicle can then adjust its network parameters dynamically dependent on its location. A vehicle may maintain multiple connections to different networks concurrently for transmitting duplicate data of a data stream, with the vehicle independently adjusting parameters associated with different networks to optimize performance.
