Consider the timeline below with four nodes A, B, C, and D. A B D a S 9 h I 'm n C d e u List the Lamport timestamps for each event shown in the timeline. Assume that each process maintains a logical clock as a single integer value starting at 0 as a Lamport clock. Provide timestamps for each labeled event a..u in the table below. Event Lamport ts Event Lamport ts Event Lamport ts Event Lamport ts b d a e j n g 09 k 0 S h 1 P t i m 9 u List the Vector timestamps for each event shown in the timeline in the table below. Assume that each process maintains a logical clock as a four-element vector starting at (0, 0, 0, 0) as a vector clock. Event a e j n r Vector ts Event Vector ts b g k 0 S Event Vector ts h 1 P Event d i m q Vector ts Recall that we can detect a causality violation using vector timestamps by comparing the timestamp of a newly received message to the local time. If the message's timestamp is less than the local time vector, a (potential) causality violation has occurred. In this timeline, did any causality violations occur? If so, which event(s) do these correspond to?
