Abstract: A communication system is disclosed in which a ProSe Relay UE allows a remote UE to connect to a base station and core network through the Relay UE. The base station broadcasts that it is capable of supporting ProSe Relay UEs. UEs that are in poor coverage areas can identify that the base station supports ProSe Relaying and can search for a relay UE with which to connect prior to trying to establish a direct connection with the base station. The Relay UE and the base station maintain context information for the relayed UE so that messages can be properly routed through the network and through the Relay UE.

Abstract: Systems and methods are described for automatically controlling network routing between downstream side and upstream side of a communication network to enforce symmetric routing. According to one embodiment, a Software-Defined Wide Area Network (SDWAN) controller of a network device associated with a spoke site of an SDWAN manages links forming the SDWAN. The controller receives information regarding route maps, including a preferred route-map and an un-preferred route-map. Further, the controller configures a local BGP daemon with the route maps to exchange routing information including a BGP attribute with the BGP peers and selects a link on which network traffic is to be transmitted. The controller causes the BGP daemon to (i) use the preferred route-map to advertise the routing information to the BGP peer associated with the selected link, and (ii) use the un-preferred route-map to advertise the routing information to a remainder of the BGP peers.

Abstract: Methods, systems, and devices for wireless communications are described. A first device may identify that a first set of transmission resources in a transmission time interval (TTI) has a higher priority at a second device than a second set of transmission resources in the TTI. The first device may identify that a message is to be transmitted from the first device to the second device via the TTI and process the message into a bit sequence based on the identification of the second set of transmission resources in the TTI, where the processing increases a likelihood that systematic bits of the message are received at the second device despite presence of the second set of transmission resources in the TTI. The first device may transmit the bit sequence to the second device via the TTI.

Abstract: Techniques are described for managing a split-brain scenario in a multihomed environment by exchanging isolation information between a leaf device and two or more spine devices to which the leaf device is multihomed via a link aggregation group (LAG). The techniques include selecting one of the spine devices as a primary spine device and determining, based on the isolation information, whether the spine devices are isolated from each other. In the split-brain scenario in which all of the spine devices are isolated from each other, the primary spine device is configured to maintain the LAG with the leaf device while the other spine devices mark the LAG with the leaf device as down. In this way, in the split-brain scenario, the leaf device may continue to send traffic to other leaf devices in the leaf layer using the LAG to the primary spine device.
