  • Distributed transmission of messages in a communication network with selective multi-region replication
    Patent number: 11323538
    Abstract: To distribute messages to subscribers that are located in multiple regions, a data center will receive messages that to be published to the subscribers. For each message, the data center will determine a channel on which the message is to be published. For any given channel, the data center will then perform a limited replication process to other data centers in other regions by accessing an interest map indicating additional data centers at which subscribers to the channel have recently expressed interest. The data center will transmit the messages that are associated with the channel to only that group of additional data centers for replication but not to other data centers at which no interest has been recently expressed.
