Cons of the Bully algorithm
- Inefficient in large networks: The bully algorithm can introduce message overhead and delays in larger distributed systems.
- Risk of starvation: Lower-ranked nodes may never become leaders in some cases.
- Initialization challenges: The bully algorithm requires accurate Process rankings, which can be difficult to achieve in practice.
- Lack of preemption: The bully algorithm is non-preemptive, meaning that the current leader cannot be preempted by a higher-ranked Process.
Bully Algorithm in Distributed System
Operating Systems play a critical role in managing and coordinating the activities of a computer system. In distributed systems, where multiple computers work together to achieve a common goal, the issue of node/process failure becomes a significant concern. To ensure the reliability and fault tolerance of a distributed system, leader election algorithms come to the rescue. In this article, we will discuss the leader election algorithm (Bully algorithm) and understand how it guarantees the election of a new coordinator when the current coordinator fails.
