With GBN, it is possible for the sender to receive an ACK for a packet that falls outside of its current window. c. The alternating-bit protocol is the same as the SR protocol with a sender and receiver window size of 1. d. The alternating-bit protocol is the same as the GBN protocol with a sender and receiver window size of 1.

WebA sliding window protocol is a feature of packet-based data transmission protocols. Sliding window protocols are used where reliable in-order delivery of packets is required, such as in the data link layer ( OSI layer 2) as well as in the Transmission Control Protocol (TCP). They are also used to improve efficiency when the channel may include ... WebDraw the operations of the three protocols, GBN, SR, and TCP. For each segment sent, labeled it with the sequence number; and for each acknowledgement, labeled it with the sequence number too. You can assume that for TCP, the initial sequence number is 120, and the each segment contains 1000 bytes of data.
