Dynamically configured overlay multicast
A participant in a network is configured to query a data storage system to determine whether there have been any changes to a network. The participant receives a response to the query and determines, based at least in part on the response, whether reconfiguration is necessary. If the network has changed (e.g., if the network topology has changed), as indicated in the response, the system performs one or more actions in accordance with the response. Multiple participants in the network may query the data storage system so that, collectively, network updates are initiated by changes to data in the data storage system. The network may be an overlay network that allows communication according to a communication protocol, such as multicast, that may not be completely supported by a physical network substrate.
Systems and methods for dynamically switching between unicast and multicast delivery of media content in a wireless network
Systems and methods for dynamically switching between unicast and multicast delivery of media content are disclosed. An exemplary method includes a user device 1) accessing, over a wireless network, a unicast stream carrying data representative of a media content program, 2) detecting, during the accessing of the unicast stream, an instruction to switch to a multicast stream carrying data representative of the media content program, and 3) switching, in response to the instruction, from the accessing of the unicast stream to accessing the multicast stream by way of the wireless network. Corresponding systems and methods are also disclosed.
Communication control method and user terminal
A communication control method for performing an offload from a cellular RAN to a wireless LAN, includes a step of performing, by a user terminal, a network selection operation to select an appropriate access network with which a traffic of the user terminal is exchanged, from the cellular RAN and the wireless LAN on the basis of determination parameters. The determination parameters comprises at least one of: a cellular network status that is a network status concerning the cellular RAN; a wireless LAN network status that is a network status concerning the wireless LAN; a cellular radio link status that is a radio link status between the cellular RAN and the user terminal; and a wireless LAN radio link status that is a radio link status between the wireless LAN and the user terminal.
Communication control method and user terminal
A method, base station, and device perform an offload from a cellular RAN to a wireless LAN via a network selection operation to select an access network with which user terminal traffic is exchanged from the cellular RAN and the wireless LAN on the basis of parameters transmitted from a first base station to the user terminal. The parameters comprise at least one of a cellular signal strength threshold, a WLAN signal strength threshold, and a WLAN load threshold. After transmitting the parameters, the transmitted parameters are transferred from the first cellular base station to a second cellular base station, in response to the user terminal performing a handover from the first cellular base station to the second cellular base station. The transferred parameters enable the second cellular base station to determine whether there is a need for a change of configuration indicated by the transferred parameters.

Method, electronic device, and computer program product for address encryption
Embodiments of the present disclosure provide a method, an electronic device, and a computer program product that involve address encryption. The method includes: in response to receiving a packet from a source device, extracting a first address representing an address of the source device from the packet. The method further includes: mixing the first address with a random number to generate a mixed address, wherein the number of bits of the first address is the same as the number of bits of the random number. The method further includes: encrypting the mixed address. Moreover, the method further includes: generating a second address representing the address of the source device at least partially based on the encrypted mixed address, wherein the second address includes a prefix field and an interface identifier field. Illustrative embodiments can improve the security of the source device, and reduce computational overhead during address encryption and decryption.
