Abstract: A method and system for distributing messages sent from senders to receivers in a reliable and real-time manner. Some of the receivers are designated as recording receivers that are responsible for recording each message that it receives so it can provide to other receivers messages they have missed. When a sender distributes a message, it waits for an acknowledgement from a recorder that it received and recorded the message. If an acknowledgement is received, then the sender knows at least one recorder has a copy of the message that that recorder can provide to other receivers that missed the message. When a receiver detects that it missed a message, it then initiates a “hole filling” process that distributes a request for the missing message to the recorders. A recorder who can provide the missing message sends to the requesting receiver a response indicating it can provide the missing message.
