    Description: 
broker network setup with mqtt enabled.

scenario:

Client (C1) connects to MQ1
C1 publishes message M1 to topic T1

C1 publishes message M2,M3 to topic T1 and disconnects.

  was:
broker network setup with mqtt enabled.

scenario:

Client (C1) connects to MQ1
Client (C2) sends a message (M1) to C1
Mq1 receives the message M1. 
Mq1 initiates publishing of M1 to C1.
In between the publish process (PUB/PUB REC/PUB REL/PUB COM) , C1 disconnects
C1 connects back to MQ2
C2 sends a message (M2) . M2 reaches MQ2 and MQ2 immediately starts the publish process 
MQ1 starts the process of publishing  M1, which now gets routed to MQ2 and then get published to C1
C1 receives M2 and then M1.
