Overview

Objective:

• Generate a network consisting of 16 nodes running simultaneously where one node can at maximun know only three other nodes and disseminate broadcast message using gossip protocol.

Methodology:

• Each node has two API methods submit_message and get message. They can be viewed in Gossip.py

• UDP for communication

• Every node will receive the message, a node transmits using gossip dissemination.

• Figure of gossip dissemination shown below

Instructions

Step 1: Start the Gossip Nodes

#TODO(Koushikg): dockerize nodes so it is easier to setup env

• start nodes separately in each terminal

python Gossip_node_7000.py

Step 2: Enter a message

• Enter a message from any node and view other node's terminal as the message is received

Node started on port 7000
Susceptible nodes => [7010, 7020]
Enter a message to send:

hello from 7000
