Lamport’s ME Algorithm The context for this question is the same as the previous question. Consider a distributed system with 3 nodes (P1, P2, P3) implementing Lamport’s mutual exclusion algorithm, as shown in the Figure. The boxes represent requests made by a node at a particular timestamp. For example, P1,4 represents a request for the resource made by node P1 at timestamp 4. The red arrows represent requests, and green arrows represent the corresponding acknowledgment messages. c) Suggest a simple method to prevent the algorithm from failing due to message loss.

Spring OS Your coworker is debugging a distributed payment processing service built on Spring OS. Currently, the client process hangs when ‘invoice.submit()’ is called. The client process runs on Node A, but the invoice service object lives on Node B on a LAN. Your coworker would like to better understand the runtime plumbing so they can trace, reproduce, and fix the bug. a) What is a ‘door’ and what is a ‘network proxy’ in this setting, and why are they essential for communication between the client and the invoice service?
