Abstract:
When a new broker is connected to a network, a loop detection message is sent over the new connection created by the new broker. The loop detection message includes topics. At each receiving broker, topics that cannot be propagated to a neighbor broker are removed. If the loop detect message contains no topics, the loop detect message is not propagated further. If the loop detection message returns to the new broker, a loop is detected.
