  • Method for handling of an inbound SCTP packet at an SCTP load balancer and tunneling methodology
    Patent number: 11973822
    Abstract: Methods and systems for handling of an inbound Stream Control Transmission Protocol (SCTP) packet at an SCTP load balancer (SCTP LB) are described. In one embodiment a method includes receiving, at the SCTP LB, an SCTP packet; determining, by the SCTP LB, which tunneling mechanism to use for the SCTP packet; and tunneling the SCTP packet to a correct back-end server for further processing of the SCTP packet.

  • Slow eNodeB/HNB identification and impact mitigation
    Patent number: 11611898
    Abstract: A method and computer readable medium for identifying slow base stations and providing impact mitigation are described. In one embodiment, the method includes detecting that a first base station, using a first queue, is slow, wherein a slow base station is a base station that that cannot keep up with the rate at which a core node is generating update messages over a prolonged period; providing a slow base station queue; and moving the first base station from the first queue to the slow base station queue.

  • Methodology for Achieving Highly Scalable and Distributed Secured Connectivity per IPSEC Tunnel
    Publication number: 20230029064
    Abstract: Methods, systems and computer readable media are disclosed for providing scalable and secured connectivity per Internet Protocol Security (IPSEC) tunnel. In one embodiment a method includes spreading Encapsulating Security Payload (ESP) encryption for a same IPSEC tunnel across multiple backend application servers; and processing application flows using decrypted packets by embedding the Application Server instance-id in ESP and application packets for correlation with application packet flows.

  • Handling of SCTP Packets with T-bit Set at SCTP Load Balancer
    Publication number: 20220217225
    Abstract: Systems, methods and computer software are disclosed for handling Stream Control Transmission Protocol (SCTP) packets with T-bit set at an SCTP load balancer. In one embodiment a method is disclosed, the method including embedding bits in an SCTP verification tag during SCTP association to identify a correct backend-server instance; parsing the verification tag to obtain an embedded instance number of the backend server; and routing, based on the embedded instance number, the SCTP packets to a correct backend server for further processing.
