Consider the token ring network in Figure below. Token is circulating between stations in the following sequence: A- B- C- D E- F A. Single token operation is implemented and 8 priority levels supported, with level 0 the highest priority while level 7 is the lowest. The following data frames will be delivered by this network: Frame 1 from Node B, at priority level 4; Frame 2 from Node C at priority level 2, Frame 3 from Node D at priority level 1, Frame 4 from node F, at priority level 4. At the beginning, a free token with priority level 3 and reservation level 7 is released by node A. What is the sequence these four frames will be delivered? Justify your
