Consider the token ring network in Figure. Token is circulating between stations in the following

sequence: A$,$B$,$C$,$D$,$E$,$A$.$ Single token operation is implemented and $8$ priority levels are

supported, with level $0$ is the highest priority while level $7$ is the lowest. The following data

frames are ready to be delivered by this network: Frame $1$ from Node B$,$ at priority level $5$;

Frame $2,$ from Node C$,$ at priority level $3$; Frame $3,$ from Node D$,$ at priority level $1$; Frame $4,$

from node E$,$ at priority level $3.$ At the beginning, a free token with priority level $5$ and

reservation level $7$ arrives at node $A.$

What is the sequence these four frames will be delivered? Justify your answer.
