Unformatted text preview: and may give a better performance comparing with multicast algorithm as its number of message for synchronization is similar. Discuss the main performance tradeoffs between the use of central server and the multicast method. Question 2 Why deadlock is possible in the Maekawas algorithm but not possible in the multicast algorithm? Give an example deadlock case using the Maekawas algorithm. Question 3 Explain the main differences in mechanisms between the Maekawas algorithm and the multicast algorithm. Question 4 What are the assumptions of the Bully algorithms? Question 5 What are the requirements the consensus problem?...
