  • Bypass delivery policy based on the usage (I/O operation) of caching memory storage in CDN
    Patent number: 11297155
    Abstract: A request router is disclosed for a multi-tier Content Delivery Network (CDN), each tier corresponding to a hierarchical layer of the CDN. The request router includes processing circuitry configured to: receive, from a first delivery node of a hierarchical layer of the CDN, a routing request to bypass the first delivery node for content delivery to a user equipment; and as a result of receiving the routing request to bypass the first delivery node for the content delivery to the user equipment, select at least a second delivery node for the content delivery to the user equipment.
    Type: Grant

  • Multicast group reuse in cellular network multicase transport
    Patent number: 9456315
    Abstract: For transmission of multicast data in a cellular network, a gateway (200) allocates a set of multicast sessions (111, 112) to a single Internet Protocol Multicast group (110). For each of the multicast sessions (111, 112), the gateway indicates an Internet Protocol Multicast address of the Internet Protocol Multicast group to one or more radio access network nodes (100) of the cellular network. For each of the multicast sessions (111, 112), the gateway (200) indicates a different identifier to the radio access network nodes (100), e.g., in the form of a Tunnel Endpoint Identifier. The gateway (200) sends multicast data of the multicast sessions (111, 112) in one or more Internet Protocol Multicast data packets addressed to the Internet Protocol Multicast address of the Internet Protocol Multicast group. The multicast data of each of the multicast sessions (111, 112) include the respective identifier to allow identification of the multicast session (111, 112) at the radio access network node (100).
