 default, the communication layer will send the message to all the nodes. 
 
-Since, the ACL/LCT implementation is not fully reliable in the sense that it doesn't guarantee
- reliable delivery, is the reason for putting a error correction mechanism on top.
-The NodeHandler will then wait for ACKs from the NodeAgent, which will be received through the 
-TCP socket. The communication server, after a pre-defined interval, will repeatedly send the

+After a message is sent, the communication server will wait for ACKs from the NodeAgent, which

+done by the communication server. Also, it will, after a pre-defined interval, repeatedly send

+This amounts to an error correcting mechanism on top of reliable multicast, but it has been 
+deemed necessary because the ACL/LCT implementation is not fully reliable in the sense that it
+doesn't guarantee reliable delivery,
