  • Patent number: 11228937
    Abstract: Embodiments concern managing traffic in a radio device. While classifying user-plane packets from multiple applications according to quality of service requirements, a specific user-plane packet is classified as/determined to be a predetermined special-type packet (e.g., the special-type packets establish a new TCP/IP connection for a newly activated application). Based on that, that specific user-plane packet is mapped to a pre-defined radio bearer associated with a preconfigured priority, for example a highest priority among all bearers to which any of these user-plane packets from the multiple applications are mapped. Then all the mapped user-plane packets are scheduled for transmission according to their respective priorities. For example, the specific user-plane packet could be a SDU having a SYN, SYN-ACK or ACK, and the network convergence sub-layer (NCS) constructs a L2 NCS PDU using a designated format with the SDU in the payload and context information in the header.

  • Patent number: 11223565
    Abstract: MPTCP connections and their corresponding TCP subfiows are routed by a load balancer toward backends. Each MPTCP connection is routed to a single backend and is able to include primary and secondary TCP subfiows. Routing includes performing, responsive to setting up a primary TCP subflow of an MPTCP connection, load balancing of the connection to select a backend for the connection. The MPTCP connections and their TCP subflows are tracked by the load balancer to route the MPTCP connections and their corresponding TCP subfiows to corresponding selected backends. A backend determines whether a request by a client to set up a primary TCP subflow of an MPTCP connection already includes a key used to generate a token used to uniquely identify the MPTCP connection from other MPTCP connections. The backend generates the token based on the key. The backend uses the token to distinguish subsequent communications for the MPTCP connection.
