Hi, I am trying to make an ActiveMQ network of brokers work over different subnetworks. Inside the subnetworks I use multicast for auto discovery between the brokers, but this isn't an option for connecting brokers in different subnets. The requirements are that each subnet can have publishers and subscribers and that subscribers can subscribe to topics produced in a a different subnet. I am not concerned with queues at the moment. To provide communication across subnets, in each subnet, I use two special brokers that are supporting the communication with the other subnet. One broker is just for receiving and the other is just for sending. The configuration for the brokers is like this:
1. Broker inside each subnet: <networkConnectors> <networkConnector uri="multicast://default" dynamicOnly = "true" prefetchSize = "1" /> <networkConnector uri="static://(tcp://OutHost:61617)" name = "toOutside" duplex = "false" dynamicOnly = "false" networkTTL = "1"/> <networkConnector uri="static://(tcp://InHost:61618)" name = "fromOutside" duplex = "true" dynamicOnly = "false" networkTTL = "3"> <excludedDestinations> <topic physicalName = "MyTopic" /> </excludedDestinations> </networkConnector> </networkConnectors> <transportConnectors> <transportConnector uri="tcp://0.0.0.0:61616?transport.keepAliveResponseRequired=true" discoveryUri="multicast://default" /> </transportConnectors> 2. Broker that is sending to the other subnetwork(OutHost): <networkConnectors> <networkConnector uri="static://(tcp://OutsideHost:61619)" duplex = "false" dynamicOnly = "false" networkTTL = "2"/> </networkConnectors> <transportConnectors> <transportConnector uri="tcp://0.0.0.0:61617?transport.keepAliveResponseRequired=true" /> </transportConnectors> 3.Broker that is receiving from the other subnetwork(InHost): <networkConnectors/> <transportConnectors> <transportConnector name="Subnet" uri="tcp://0.0.0.0:61618?transport.keepAliveResponseRequired=true" /> <transportConnector name="Outside" uri="tcp://0.0.0.0:61619? transport.keepAliveResponseRequired=true" /> </transportConnectors> I've run some tests with 2 subnetworks, 2 non-special brokers on each subnetwork and 2 clients on each broker. One of these clients publishes on its own topic and the other client subscribes to all four topics. All the brokers are configured with the persistent attribute set to false and all consumers are not durable. There are several problems that I cannot figure out. 1.Unless I start clients that subscribe to the topics on OutHost for subnet1 and on InHost for subnet2 messages are not passing from subnet1 to subnet2, and vice versa. As long as the chain of connections between a inner broker on subnet1 and a inner broker on subnet2 contains only connections with dynamicOnly set to false shouldn't this not happen? 2.Sometimes I am receiving duplicate messages on the final clients(those on the brokers inside the subnets) or sometimes messages on this clients are missing. The duplicated messages are coming from the other subnet. Maybe my broker topology is too complicated and all I want to achieve can be done in a simpler way. Any advice would be very helpful.
