Abstract
Reconfiguration of a continuously available routing network of a publish/subscribe system is achieved by quiescing data messages and control messages within the routing network to preserve first-in first-out ordering thereof, and then, reconfiguring the quiesced routing network. This reconfiguration technique is particularly applicable to a routing network having at least one special node comprising one of a logger node or a sequencer node, wherein the logger node is used to store a message to persistent storage within the routing network prior to delivery of the message to one or more clients, and the sequencer sequences a message with other messages received by the network prior to delivery thereof for ordered delivery of the messages to one or more clients of the network.
