If I want to connect to a SMSC over 5 binds (smpp sessions) what I am doing is this:
public void configure(MessageForwardingService messageForwardingService,
MessageLoggingService messageLoggingService) {
int sessionNum = connectionProperties.get(ConnectionConstants.OPERATOR_CONNECTION_SESSION_NUMBER, 0);
final SmppClientMessageService smppClientMessageService = new CommXPSmppClientMessageService(operatorName,
messageForwardingService, messageLoggingService, applicationEventPublisher);
for (int i = 0; i < sessionNum; i++) {
OutboundClient client = new OutboundClient(
connectionProperties.get(ConnectionConstants.OPERATOR_CONNECTION_ENQUIRELINK_TIMER, 10000),
connectionProperties.get(ConnectionConstants.OPERATOR_CONNECTION_ENQUIRELINK_TIMER, 30000));
client.initialize(getSmppConnectionConfiguration(i), smppClientMessageService);
balancedList.set(client, 1);
}
}
public OutboundClient(final Integer endquireLinkPeriod, Integer enquireLinkTimeout) {
this.enquireLinkPeriod = endquireLinkPeriod;
this.enquireLinkTimeout = enquireLinkTimeout;
this.enquireLinkExecutor = Executors.newScheduledThreadPool(1, new ThreadFactory() {
@Override
public Thread newThread(Runnable r) {
Thread t = new Thread(r);
String name = config.getName();
t.setName("EnquireLink-" + name);
return t;
}
});
monitorExecutor = (ScheduledThreadPoolExecutor) Executors.newScheduledThreadPool(1, new ThreadFactory() {
private AtomicInteger sequence = new AtomicInteger(0);
@Override
public Thread newThread(Runnable r) {
Thread t = new Thread(r);
t.setName("SmppClientSessionWindowMonitorPool-" + sequence.getAndIncrement());
return t;
}
});
NioEventLoopGroup group = new NioEventLoopGroup(1);
clientBootstrap = new DefaultSmppClient(group, monitorExecutor);
}
public void initialize(SmppSessionConfiguration config, SmppClientMessageService smppClientMessageService) {
this.config = config;
logger = LoggerFactory.getLogger(OutboundClient.class.getCanonicalName() + config.getName());
//
// setup configuration for a client session
//
sessionHandler = new ClientSmppSessionHandler(this, smppClientMessageService);
}`
Then I get each of the balancedList sessions and I submitMessages.
To my mind this is creating 5 different DefaultClients with 1 thread each. Somehow though this seems counter intuitive and I am not sure it is correct.
It works and I had great success submitting with over 200 TPS but I am worried since I started facing an issue with very heavy load for incoming messages. Is the problem related to using the sessions incorrectly or should I look elsewhere for the issue?
I know that opening an issue might not be ideal but given the limited documentation I have found on cloudhopper I thought this could be a good opportunity to add some explanation to the code samples.
