Reliable Multicast Architecture Design

Introduction

The current NodeHandler code works satisfactorily on the small grid and the sandboxes. But this same code fails to work correctly on the big grid. This is due to the fact that in the current grid consisting of 400 nodes, packet loss is a major problem. And this problem escalates sharply with the increase in the no. of nodes. Specifically, when trying to image more than 150 nodes in a single attempt, the high packet loss prevents successful completion. To alleviate this problem, it has been decided to explore the use of a reliable multicast protocol. The implementation being considered here is MCLv3, which is an Open Source Implementation of the ALC and NORM Reliable Multicast Protocols.
