Unformatted text preview: CNT 3004 Chapter 11 Homework 6 1. In VARIABLE-SIZE framing, we need a delimiter (flag) to define the boundary of two frames. 2. In CHARACTER-ORIENTED protocols, we use BYTE STUFFING 3. Flow control mechanisms with sliding windows have control variables at: BOTH SENDER AND RECEIVER SITES 4. FLOW CONTROL enables a receiver to regulate the flow of data from a sender so that the receiver's buffers do not overflow. 5. The time it takes for a station to emit all of the bits of a frame onto the medium is the TRANSMISSION time. 6. A sender send a series of packets to the same destination using 5-bit sequence numbers. If the sequence number starts with 0, what is the sequence number to be used after sending 100 packets? 4 7. Bit-stuf the data given in the following figure 0001111111001111101000111111111100011111 000111110110011111001000111110111110000111110 8. For Stop-and-Wait ARQ, for 10 data packets sent, EXACTLY 10 acknowledgments are needed 9. If two stations exchange data, each needs to maintain two windows, one for transmit and one for...
