transmit from the head of the active queue corresponding to VC i at time n. This will be modi ed below after the basic algorithm is presented. The scheduler is activated on every new frame activation, that is, on a frame clock. Let the new frame activation be at time n. (See Fig. 19.5(b).) Let the corresponding VC be i, the frame length (jitter bound) be Mi , the number of cells in the current active frame be mi , and the minimum number of cells guaranteed to be transmitted from this VC in this frame be Ci . Channel_image records the action to be taken by the transmitter in future slots. The scheduler either marks the slots in channel_image with a VC identi er or leaves them empty. If it does mark a slot, it also records whether the transmission is to be guaranteed or not-guaranteed. If a slot is marked not-guaranteed, it may be reclaimed at some point in the future to serve a different VC (as described in Section 19.2.3.1). The scheduler's task is as follows. Assume that it is activated on VC i's frame clock. The time window in the future over which the mi active cells need to be transmitted is n 1, n Mi ]. (The nth slot is kept aside for the transmission to begin transmitting.) The scheduler follows the following algorithm. (a) Beginning with n Mi , going down to n 1, the scheduler attempts to nd the largest ki mi slots that are empty in channel_image n Mi through channel_image n 1 , and marks each with the current VC, i. (b) If (ki Ci) { guaranteed_cells[i]=ki; not_guaranteed[i]=0; }else{ guaranteed_cells[i]=Ci; not_guaranteed[i]=ki-Ci; }

writePointer = (++writePointer) % size;

(c) If ki mi , the scheduler's allocation task for this frame is done Else, it needs to pick at most mi ki slots and at least Ci ki slots in channel_ image n 1 through channel_image n Mi that are marked, but not necessarily guaranteed, and overwrite them with i Each slot overwritten represents a cell loss for the corresponding VC Since this would give priority to some VCs over others when the number of active cells exceeds the capacity available (for meeting deadlines), the policy used must balance from fairness and cell-loss commitments The dropping policy is described below 19231 Dropping Policy Let the negotiated mean cell-loss ratio of VC i be Ei , ^ and the estimated cell-loss ratio at time n be Ei n Let Si n Ei =^ i n .

Hi guys, so I have been given a project to do that uses OCR to read some text from images. I've never used an OCR library so this is something very new to me.

Yang and Pan E [24] have proposed a dropping policy where, if an incoming cell arrives to a full buffer (in our case, full channel_image), the scheduler will search the buffer for the VC j that has the largest Sj n and discard one of its cells If the arriving cell belongs to VC j itself, then that cell will be dropped The authors show that using the largest Sj n is optimal in bandwidth utilization among all stationary, spaceconserving loss-scheduling schemes It is also optimal among all stationary scheduling strategies when cell-loss requirements of all VCs are equal (see Yang and Pan [24]) We modify this strategy to guarantee a minimum Ci cells=frame for individual VCs and replace negotiated mean cell-loss ratio with negotiated over ow probability.

Continuing from the point just after (c) in the cell-dispatcher's algorithm: (d) If k1 < Ci , the scheduler needs to overwrite at least Ci ki cells belonging to other VCs in channel_image It selects VCs fjg with (not_guaranteed[j]> 0 , starting with the largest Sj n , and updating Sj n as described in Yang and Pan [24] In all cases, the number of erased cells is decremented from not_guaranteed[j] guaranteed_cells[i] is incremented by the corresponding amount The latter should be equal to Ci at the end of this step This is because P equivalent bandwidth the algorithm described in Sectin 19412 ensures that i Ci is always less than or equal to available capacity Therefore, if a cell is to be dropped, P.

(e) If mi > Ci , then from the previous step, Ci cells have been scheduled. An additional li cells 0 li mi Ci may be scheduled, in which case not_guaranteed[i] will be set to li . The scheduler schedules these cells only if there exists a j such that (not_guaranteed[j]> 0) and Sj n > Si n . (f) Si n is updated with the number of dropped cells in this fame, if any, that is, with mi Ci li .
