How Does Ring Election Algorithm Work?
Below is how the ring election algorithm works:
- Step 1: Initialization: Each node in the network is assigned a unique identifier or priority.
- Step 2: Message Passing: The algorithm begins when a node initiates an election process. It sends a special message, often called an “election message” or “token,” containing its identifier, to its neighboring node(s) in the ring.
- Step 3: Comparison and Forwarding: Upon receiving the election message, each node compares the identifier in the message with its own. If the received identifier is greater than its own, it forwards the message to the next node in the ring. If the received identifier is smaller than its own, it discards the message.
- Step 4: Propagation: This process continues until the message returns to the initiating node. As the message travels around the ring, each node updates its state to reflect the highest identifier it has encountered.
- Step 5: Leader Election: Once the message returns to the initiating node, it knows it has the highest identifier in the network. It declares itself as the leader.
What is Ring Election Algorithm?
In distributed systems where computers work smoothly together, having a leader is crucial. Think of a group of friends in a circle, each with unique skills. How do they choose who leads their discussion? That’s where the Ring Election Algorithm comes in handy. It’s like a smart method for these friends, who are like computers, to independently select their leader.
