Rapid channel failure detection and recovery in wireless communication networks is needed in order to meet, among other things, carrier class Ethernet channel standards. Thus, resilient wireless packet communications is provided using a physical layer link aggregation protocol with a hardware-assisted rapid channel failure detection algorithm and load balancing, preferably in combination. This functionality may be implemented in a Gigabit Ethernet data access card with an engine configured accordingly. In networks with various topologies, these features may be provided in combination with their existing protocols.

Methods, systems, and computer programs are presented for processing Ethernet packets at a Field Programmable Gate Array (FPGA). One programmable integrated circuit includes: an internal network on chip (iNOC) comprising rows and columns; clusters, coupled to the iNOC, comprising a network access point (NAP) and programmable logic; and an Ethernet controller coupled to the iNOC. When the controller operates in packet mode, each complete inbound Ethernet packet is sent from the controller to one of the NAPs via the iNOC, where two or more NAPs are configurable to receive the complete inbound Ethernet packets from the controller. The controller is configurable to operate in quad segment interface (QSI) mode where each complete inbound Ethernet packet is broken into segments, which are sent from the controller to different NAPs via the iNOC, where two or more NAPs are configurable to receive the complete inbound Ethernet packets from the controller.

Some embodiments provide a method for performing data traffic monitoring. For each packet processing stage of a set of packet processing stages in a packet processing pipeline, the method determines whether a packet received by the packet processing pipeline specifies a set of monitoring actions to be performed on the packet. When the packet specifies a set of monitoring action, the method determines whether the monitoring actions in the set are supported by the packet processing stage. The method executes the supported monitoring actions on the packet in addition to processing the packet according to configuration data for the stage.

A method and an apparatus of establishing dual-connectivity to transmit data are disclosed. A PCell of the UE carries out a mapping function and realizes a PDCP layer, a RLC layer, a MAC layer and a physical layer, and a SCell of the UE carries out quality packet data to data radio bearer mapping and realizes a PDCP layer, a MAC layer and a physical layer, in which a core network transmits data of the UE to the PCell, the PCell maps a QoS Flow of the data of the UE which is quality packet data to a data radio bearer on a mapping layer, performs path split, transmits data of respective paths to the UE through the PCell and SCell of the UE, and the UE regroups the data of the respective paths on the PDCP layer, and transmits the regrouped data to an application layer.

Embodiments include methods for a user equipment (UE) to perform quality of experience (QoE) measurements configured by a wireless network. Such methods include receiving, from a radio access network node (RNN) in the wireless network, a QoE measurement configuration for one or more services provided by the UE application layer. Such methods include performing application-layer QoE measurements for the one or more services according to the QoE measurement configuration and sending, to or via the RNN in accordance with QoE measurement configuration, one or more messages comprising: one or more QoE measurement reports comprising results of the QoE measurements; and network assistance information (NAI) related to one or more paths that carry data associated with the one or more services. Other embodiments include complementary methods for RNNs and measurement functions, as well as UEs, RNNs, and measurement functions configured to perform such methods.

In some examples, a source device categorizes a plurality of messages for transmission to a recipient device, the plurality of messages comprising vehicle-related information. Based on the categorizing, the source device identifies selected messages of the plurality of messages to be aggregated. The source device aggregates the selected messages into a single transmission from the source device to the recipient device.
